You can then fetch - by index number any permutation of the 10**2500 permutations in a fraction - of a second as well. - - `PermSpace` allows the creation of various special kinds of permutation - spaces. For example, you can specify an integer to `n_elements` to set a - permutation length that's smaller than the sequence length. (a.k.a. - k-permutaions.) This variation of a `PermSpace` is called "partial" and - it's one of 8 different variations, that are listed below. - - - Rapplied (Range-applied): having an arbitrary sequence as a range. - To make one, pass your sequence as the first argument instead of the - length. - - - Dapplied (Domain-applied): having an arbitrary sequence as a domain. - To make one, pass a sequence into the `domain` argument. - - - Recurrent: If you provide a sequence (making the space rapplied) and - that sequence has repeating items, you've made a recurrent `PermSpace`. - It'll be shorter because all of the copies of same item will be - considered the same item. (Though they will appear more than once, - according to their count in the sequence.) - - - Fixed: Having a specified number of indices always pointing at certain - values, making the space smaller. To make one, pass a dict from each - key to the value it should be fixed to as the argument `fixed_map`. - - - Sliced: A perm space can be sliced like any Python sequence (except you - can't change the step.) To make one, use slice notation on an existing - perm space, e.g. `perm_space[56:100]`. - - - Degreed: A perm space can be limited to perms of a certain degree. (A - perm's degree is the number of transformations it takes to make it.) - To make one, pass into the `degrees` argument either a single degree - (like `5`) or a tuple of different degrees (like `(1, 3, 7)`) - - - Partial: A perm space can be partial, in which case not all elements - are used in perms. E.g. you can have a perm space of a sequence of - length 5 but with `n_elements=3`, so every perm will have only 3 items. - (These are usually called "k-permutations" in math-land.) To make one, - pass a number as the argument `n_elements`. - - - Combination: If you pass in `is_combination=True` or use the subclass - `CombSpace`, then you'll have a space of combinations (`Comb`s) instead - of perms. `Comb`s are like `Perm``s except there's no order to the - elements. (They are always forced into canonical order.) - - - Typed: If you pass in a perm subclass as `perm_type`, you'll get a typed - `PermSpace`, meaning that the perms will use the class you provide - rather than the default `Perm`. This is useful when you want to provide - extra functionality on top of `Perm` that's specific to your use case. - - Most of these variations can be used in conjuction with each other, but - some cannot. (See `variation_clashes` in `variations.py` for a list of - clashes.) - - For each of these variations, there's a function to make a perm space have - that variation and get rid of it. For example, if you want to make a normal - perm space be degreed, call `.get_degreed()` on it with the desired - degrees. If you want to make a degreed perm space non-degreed, access its - `.undegreed` property. The same is true for all other variations. - - A perm space that has none of these variations is called pure. - ''' - - __metaclass__ = PermSpaceType - - @classmethod - def coerce(cls, argument): - '''Make `argument` into something of class `cls` if it isn't.''' -

One thing that is allowed - here that `contextlib` doesn't allow is to yield the context manager itself - by doing `yield SelfHook`. - - 3. The third and novel way is by defining a class with a `manage_context` - method which returns a generator. Example: - - class MyContextManager(ContextManager): - def manage_context(self): - do_some_preparation() - with other_context_manager: - yield self - - This approach is sometimes cleaner than defining `__enter__` and - `__exit__`; especially when using another context manager inside - `manage_context`. In our example we did `with other_context_manager` in our - `manage_context`, which is shorter, more idiomatic and less - double-underscore-y than the equivalent classic definition: - - class MyContextManager(object): - def __enter__(self): - do_some_preparation() - other_context_manager.__enter__() - return self - def __exit__(self, *exc): - return other_context_manager.__exit__(*exc) - - Another advantage of this approach over `__enter__` and `__exit__` is that - it's better at handling exceptions, since any exceptions would be raised - inside `manage_context` where we could `except` them, which is much more - idiomatic than the way `__exit__` handles exceptions, which is by receiving - their type and returning whether to swallow them or not. - -These were the different ways of *defining* a context manager. Now let's see -the different ways of *using* a context manager: - - -Using context managers ----------------------- - -There are 2 different ways in which context managers can be used: - - 1.

As a decorator to a function - - @MyContextManager() - def do_stuff(): - pass # doing stuff - - When the `do_stuff` function will be called, the context manager will be - used. This functionality is also available in the standard library of - Python 3.2+ by using `contextlib.ContextDecorator`, but here it is combined - with all the other goodies given by `ContextManager`. - - -That's it.

This class does not rely on -the native control, as it is a full owner-drawn tree control. -Apart of the base functionalities of CustomTreeCtrl (described below), in addition -to the standard `wx.TreeCtrl` behaviour this class supports: - -* CheckBox-type items: checkboxes are easy to handle, just selected or unselected - state with no particular issues in handling the item's children; -* Added support for 3-state value checkbox items; -* RadioButton-type items: since I elected to put radiobuttons in CustomTreeCtrl, I - needed some way to handle them, that made sense. So, I used the following approach: - - - All peer-nodes that are radiobuttons will be mutually exclusive. In other words, - only one of a set of radiobuttons that share a common parent can be checked at - once. If a radiobutton node becomes checked, then all of its peer radiobuttons - must be unchecked. - - If a radiobutton node becomes unchecked, then all of its child nodes will become - inactive. - -* Hyperlink-type items: they look like an hyperlink, with the proper mouse cursor on - hovering; -* Multiline text items (**note**: to add a newline character in a multiline item, press - ``Shift`` + ``Enter`` as the ``Enter`` key alone is consumed by CustomTreeCtrl to finish - the editing and ``Ctrl`` + ``Enter`` is consumed by the platform for tab navigation); -* Enabling/disabling items (together with their plain or grayed out icons); -* Whatever non-toplevel widget can be attached next to an item; -* Possibility to horizontally align the widgets attached to tree items on the - same tree level. -* Default selection style, gradient (horizontal/vertical) selection style and Windows - Vista selection style; -* Customized drag and drop images built on the fly; -* Setting the CustomTreeCtrl item buttons to a personalized imagelist; -* Setting the CustomTreeCtrl check/radio item icons to a personalized imagelist; -* Changing the style of the lines that connect the items (in terms of `wx.Pen` styles); -* Using an image as a CustomTreeCtrl background (currently only in "tile" mode); -* Adding images to any item in the leftmost area of the CustomTreeCtrl client window. - -And a lot more. Check the demo for an almost complete review of the functionalities. - - -Base Functionalities -==================== - -CustomTreeCtrl supports all the wx.TreeCtrl styles, except: - -- ``TR_EXTENDED``: supports for this style is on the todo list (am I sure of this?). - -Plus it has 3 more styles to handle checkbox-type items: - -- ``TR_AUTO_CHECK_CHILD``: automatically checks/unchecks the item children; -- ``TR_AUTO_CHECK_PARENT``: automatically checks/unchecks the item parent; -- ``TR_AUTO_TOGGLE_CHILD``: automatically toggles the item children. - -And a style you can use to force the horizontal alignment of all the widgets -attached to the tree items: - -- ``TR_ALIGN_WINDOWS``: aligns horizontally the windows belongiing to the item on the - same tree level. - - -All the methods available in `wx.TreeCtrl` are also available in CustomTreeCtrl. - - -Events -====== - -All the events supported by `wx.TreeCtrl` are also available in CustomTreeCtrl, with -a few exceptions: - -- ``EVT_TREE_GET_INFO`` (don't know what this means); -- ``EVT_TREE_SET_INFO`` (don't know what this means); -- ``EVT_TREE_ITEM_MIDDLE_CLICK`` (not implemented, but easy to add); -- ``EVT_TREE_STATE_IMAGE_CLICK`` (no need for that, look at the checking events below). - -Plus, CustomTreeCtrl supports the events related to the checkbutton-type items: - -- ``EVT_TREE_ITEM_CHECKING``: an item is being checked; -- ``EVT_TREE_ITEM_CHECKED``: an item has been checked. - -And to hyperlink-type items: - -- ``EVT_TREE_ITEM_HYPERLINK``: an hyperlink item has been clicked (this event is sent - after the ``EVT_TREE_SEL_CHANGED`` event). - - -Supported Platforms -=================== - -CustomTreeCtrl has been tested on the following platforms: - * Windows (Windows XP); - * GTK (Thanks to Michele Petrazzo); - * Mac OS (Thanks to John Jackson). - - -Window Styles -============= - -This class supports the following window styles: - -============================== =========== ================================================== -Window Styles Hex Value Description -============================== =========== ================================================== -``TR_NO_BUTTONS`` 0x0 For convenience to document that no buttons are to be drawn. -``TR_SINGLE`` 0x0 For convenience to document that only one item may be selected at a time. Selecting another item causes the current selection, if any, to be deselected. This is the default. -``TR_HAS_BUTTONS`` 0x1 Use this style to show + and - buttons to the left of parent items. -``TR_NO_LINES`` 0x4 Use this style to hide vertical level connectors. -``TR_LINES_AT_ROOT`` 0x8 Use this style to show lines between root nodes. Only applicable if ``TR_HIDE_ROOT`` is set and ``TR_NO_LINES`` is not set. -``TR_DEFAULT_STYLE`` 0x9 The set of flags that are closest to the defaults for the native control for a particular toolkit. -``TR_TWIST_BUTTONS`` 0x10 Use old Mac-twist style buttons. -``TR_MULTIPLE`` 0x20 Use this style to allow a range of items to be selected. If a second range is selected, the current range, if any, is deselected. -``TR_EXTENDED`` 0x40 Use this style to allow disjoint items to be selected. (Only partially implemented; may not work in all cases). -``TR_HAS_VARIABLE_ROW_HEIGHT`` 0x80 Use this style to cause row heights to be just big enough to fit the content. If not set, all rows use the largest row height. The default is that this flag is unset. -``TR_EDIT_LABELS`` 0x200 Use this style if you wish the user to be able to edit labels in the tree control. -``TR_ROW_LINES`` 0x400 Use this style to draw a contrasting border between displayed rows. -``TR_HIDE_ROOT`` 0x800 Use this style to suppress the display of the root node, effectively causing the first-level nodes to appear as a series of root nodes. -``TR_FULL_ROW_HIGHLIGHT`` 0x2000 Use this style to have the background colour and the selection highlight extend over the entire horizontal row of the tree control window. -``TR_AUTO_CHECK_CHILD`` 0x4000 Only meaningful foe checkbox-type items: when a parent item is checked/unchecked its children are checked/unchecked as well. -``TR_AUTO_TOGGLE_CHILD`` 0x8000 Only meaningful foe checkbox-type items: when a parent item is checked/unchecked its children are toggled accordingly. -``TR_AUTO_CHECK_PARENT`` 0x10000 Only meaningful foe checkbox-type items: when a child item is checked/unchecked its parent item is checked/unchecked as well. -``TR_ALIGN_WINDOWS`` 0x20000 Flag used to align windows (in items with windows) at the same horizontal position. -============================== =========== ================================================== - - -Events Processing -================= - -This class processes the following events: - -============================== ================================================== -Event Name Description -============================== ================================================== -``EVT_TREE_BEGIN_DRAG`` Begin dragging with the left mouse button. -``EVT_TREE_BEGIN_LABEL_EDIT`` Begin editing a label. This can be prevented by calling `Veto()`. -``EVT_TREE_BEGIN_RDRAG`` Begin dragging with the right mouse button. -``EVT_TREE_DELETE_ITEM`` Delete an item. -``EVT_TREE_END_DRAG`` End dragging with the left or right mouse button. -``EVT_TREE_END_LABEL_EDIT`` End editing a label. This can be prevented by calling `Veto()`. -``EVT_TREE_GET_INFO`` Request information from the application (not implemented in `CustomTreeCtrl`). -``EVT_TREE_ITEM_ACTIVATED`` The item has been activated, i.e. chosen by double clicking it with mouse or from keyboard. -``EVT_TREE_ITEM_CHECKED`` A checkbox or radiobox type item has been checked. -``EVT_TREE_ITEM_CHECKING`` A checkbox or radiobox type item is being checked. -``EVT_TREE_ITEM_COLLAPSED`` The item has been collapsed. -``EVT_TREE_ITEM_COLLAPSING`` The item is being collapsed. This can be prevented by calling `Veto()`. -``EVT_TREE_ITEM_EXPANDED`` The item has been expanded. -``EVT_TREE_ITEM_EXPANDING`` The item is being expanded. This can be prevented by calling `Veto()`. -``EVT_TREE_ITEM_GETTOOLTIP`` The opportunity to set the item tooltip is being given to the application (call `TreeEvent.SetToolTip`). -``EVT_TREE_ITEM_HYPERLINK`` An hyperlink type item has been clicked. -``EVT_TREE_ITEM_MENU`` The context menu for the selected item has been requested, either by a right click or by using the menu key. -``EVT_TREE_ITEM_MIDDLE_CLICK`` The user has clicked the item with the middle mouse button (not implemented in `CustomTreeCtrl`). -``EVT_TREE_ITEM_RIGHT_CLICK`` The user has clicked the item with the right mouse button. -``EVT_TREE_KEY_DOWN`` A key has been pressed. -``EVT_TREE_SEL_CHANGED`` Selection has changed. -``EVT_TREE_SEL_CHANGING`` Selection is changing. This can be prevented by calling `Veto()`. -``EVT_TREE_SET_INFO`` Information is being supplied to the application (not implemented in `CustomTreeCtrl`). -``EVT_TREE_STATE_IMAGE_CLICK`` The state image has been clicked (not implemented in `CustomTreeCtrl`). -============================== ================================================== - - -License And Version -=================== - -CustomTreeCtrl is distributed under the wxPython license. - -Latest Revision: Andrea Gavana @ 28 Nov 2010, 16.00 GMT - -Version 2.3 - -""" - -# Version Info -__version__ = "2.3" - -import wx -from wx.lib.expando import ExpandoTextCtrl - -# ---------------------------------------------------------------------------- -# Constants -# ---------------------------------------------------------------------------- - -_NO_IMAGE = -1 -_PIXELS_PER_UNIT = 10 - -# Start editing the current item after half a second (if the mouse hasn't -# been clicked/moved) -_DELAY = 500 - -# wxPython version string -_VERSION_STRING = wx.VERSION_STRING - -# ---------------------------------------------------------------------------- -# Constants -# ---------------------------------------------------------------------------- - -# Enum for different images associated with a treectrl item -TreeItemIcon_Normal = 0 # not selected, not expanded -TreeItemIcon_Selected = 1 # selected, not expanded -TreeItemIcon_Expanded = 2 # not selected, expanded -TreeItemIcon_SelectedExpanded = 3 # selected, expanded - -TreeItemIcon_Checked = 0 # check button, checked -TreeItemIcon_NotChecked = 1 # check button, not checked -TreeItemIcon_Undetermined = 2 # check button, undetermined -TreeItemIcon_Flagged = 3 # radio button, selected -TreeItemIcon_NotFlagged = 4 # radio button, not selected - -# ---------------------------------------------------------------------------- -# CustomTreeCtrl flags -# ---------------------------------------------------------------------------- - -TR_NO_BUTTONS = wx.TR_NO_BUTTONS # for convenience -""" For convenience to document that no buttons are to be drawn.

This is the default. - ``TR_HAS_BUTTONS`` 0x1 Use this style to show + and - buttons to the left of parent items. - ``TR_NO_LINES`` 0x4 Use this style to hide vertical level connectors. - ``TR_LINES_AT_ROOT`` 0x8 Use this style to show lines between root nodes. Only applicable if ``TR_HIDE_ROOT`` is set and ``TR_NO_LINES`` is not set. - ``TR_DEFAULT_STYLE`` 0x9 The set of flags that are closest to the defaults for the native control for a particular toolkit. - ``TR_TWIST_BUTTONS`` 0x10 Use old Mac-twist style buttons. - ``TR_MULTIPLE`` 0x20 Use this style to allow a range of items to be selected. If a second range is selected, the current range, if any, is deselected. - ``TR_EXTENDED`` 0x40 Use this style to allow disjoint items to be selected. (Only partially implemented; may not work in all cases). - ``TR_HAS_VARIABLE_ROW_HEIGHT`` 0x80 Use this style to cause row heights to be just big enough to fit the content. If not set, all rows use the largest row height. The default is that this flag is unset. - ``TR_EDIT_LABELS`` 0x200 Use this style if you wish the user to be able to edit labels in the tree control. - ``TR_ROW_LINES`` 0x400 Use this style to draw a contrasting border between displayed rows. - ``TR_HIDE_ROOT`` 0x800 Use this style to suppress the display of the root node, effectively causing the first-level nodes to appear as a series of root nodes. - ``TR_FULL_ROW_HIGHLIGHT`` 0x2000 Use this style to have the background colour and the selection highlight extend over the entire horizontal row of the tree control window. - ``TR_AUTO_CHECK_CHILD`` 0x4000 Only meaningful foe checkbox-type items: when a parent item is checked/unchecked its children are checked/unchecked as well. - ``TR_AUTO_TOGGLE_CHILD`` 0x8000 Only meaningful foe checkbox-type items: when a parent item is checked/unchecked its children are toggled accordingly. -

This class does -not rely on the native control, as it is a full owner-drawn tree-list control. - -HyperTreeList is somewhat an hybrid between L{CustomTreeCtrl} and `wx.gizmos.TreeListCtrl`. - -In addition to the standard `wx.gizmos.TreeListCtrl` behaviour this class supports: - -* CheckBox-type items: checkboxes are easy to handle, just selected or unselected - state with no particular issues in handling the item's children; -* Added support for 3-state value checkbox items; -* RadioButton-type items: since I elected to put radiobuttons in CustomTreeCtrl, I - needed some way to handle them, that made sense. So, I used the following approach: - - - All peer-nodes that are radiobuttons will be mutually exclusive. In other words, - only one of a set of radiobuttons that share a common parent can be checked at - once. If a radiobutton node becomes checked, then all of its peer radiobuttons - must be unchecked. - - If a radiobutton node becomes unchecked, then all of its child nodes will become - inactive. - -* Hyperlink-type items: they look like an hyperlink, with the proper mouse cursor on - hovering; -* Multiline text items; -* Enabling/disabling items (together with their plain or grayed out icons); -* Whatever non-toplevel widget can be attached next to a tree item; -* Whatever non-toplevel widget can be attached next to a list item; -* Column headers are fully customizable in terms of icons, colour, font, alignment etc...; -* Default selection style, gradient (horizontal/vertical) selection style and Windows - Vista selection style; -* Customized drag and drop images built on the fly; -* Setting the HyperTreeList item buttons to a personalized imagelist; -* Setting the HyperTreeList check/radio item icons to a personalized imagelist; -* Changing the style of the lines that connect the items (in terms of `wx.Pen` styles); -* Using an image as a HyperTreeList background (currently only in "tile" mode); - -And a lot more. Check the demo for an almost complete review of the functionalities. - - -Base Functionalities -==================== - -HyperTreeList supports all the `wx.gizmos.TreeListCtrl` styles, except: - -- ``TR_EXTENDED``: supports for this style is on the todo list (Am I sure of this?). - -Plus it has 3 more styles to handle checkbox-type items: - -- ``TR_AUTO_CHECK_CHILD``: automatically checks/unchecks the item children; -- ``TR_AUTO_CHECK_PARENT``: automatically checks/unchecks the item parent; -- ``TR_AUTO_TOGGLE_CHILD``: automatically toggles the item children. - -And a style useful to hide the TreeListCtrl header: - -- ``TR_NO_HEADER``: hides the HyperTreeList header. - - -All the methods available in `wx.gizmos.TreeListCtrl` are also available in HyperTreeList. - - -Events -====== - -All the events supported by `wx.gizmos.TreeListCtrl` are also available in HyperTreeList, -with a few exceptions: - -- ``EVT_TREE_GET_INFO`` (don't know what this means); -- ``EVT_TREE_SET_INFO`` (don't know what this means); -- ``EVT_TREE_ITEM_MIDDLE_CLICK`` (not implemented, but easy to add); -- ``EVT_TREE_STATE_IMAGE_CLICK`` (no need for that, look at the checking events below). - -Plus, HyperTreeList supports the events related to the checkbutton-type items: - -- ``EVT_TREE_ITEM_CHECKING``: an item is being checked; -- ``EVT_TREE_ITEM_CHECKED``: an item has been checked. - -And to hyperlink-type items: - -- ``EVT_TREE_ITEM_HYPERLINK``: an hyperlink item has been clicked (this event is sent - after the ``EVT_TREE_SEL_CHANGED`` event). - - -Supported Platforms -=================== - -HyperTreeList has been tested on the following platforms: - * Windows (Windows XP); - - -Window Styles -============= - -This class supports the following window styles: - -============================== =========== ================================================== -Window Styles Hex Value Description -============================== =========== ================================================== -``TR_NO_BUTTONS`` 0x0 For convenience to document that no buttons are to be drawn. -``TR_SINGLE`` 0x0 For convenience to document that only one item may be selected at a time. Selecting another item causes the current selection, if any, to be deselected. This is the default. -``TR_HAS_BUTTONS`` 0x1 Use this style to show + and - buttons to the left of parent items. -``TR_NO_LINES`` 0x4 Use this style to hide vertical level connectors. -``TR_LINES_AT_ROOT`` 0x8 Use this style to show lines between root nodes. Only applicable if ``TR_HIDE_ROOT`` is set and ``TR_NO_LINES`` is not set. -``TR_DEFAULT_STYLE`` 0x9 No Docs -``TR_TWIST_BUTTONS`` 0x10 Use old Mac-twist style buttons. -``TR_MULTIPLE`` 0x20 Use this style to allow a range of items to be selected. If a second range is selected, the current range, if any, is deselected. -``TR_EXTENDED`` 0x40 Use this style to allow disjoint items to be selected. (Only partially implemented; may not work in all cases). -``TR_HAS_VARIABLE_ROW_HEIGHT`` 0x80 Use this style to cause row heights to be just big enough to fit the content. If not set, all rows use the largest row height. The default is that this flag is unset. -``TR_EDIT_LABELS`` 0x200 Use this style if you wish the user to be able to edit labels in the tree control. -``TR_ROW_LINES`` 0x400 Use this style to draw a contrasting border between displayed rows. -``TR_HIDE_ROOT`` 0x800 Use this style to suppress the display of the root node, effectively causing the first-level nodes to appear as a series of root nodes. -``TR_COLUMN_LINES`` 0x1000 No Docs -``TR_FULL_ROW_HIGHLIGHT`` 0x2000 Use this style to have the background colour and the selection highlight extend over the entire horizontal row of the tree control window. -``TR_AUTO_CHECK_CHILD`` 0x4000 Only meaningful foe checkbox-type items: when a parent item is checked/unchecked its children are checked/unchecked as well. -``TR_AUTO_TOGGLE_CHILD`` 0x8000 Only meaningful foe checkbox-type items: when a parent item is checked/unchecked its children are toggled accordingly. -``TR_AUTO_CHECK_PARENT`` 0x10000 Only meaningful foe checkbox-type items: when a child item is checked/unchecked its parent item is checked/unchecked as well. -``TR_ALIGN_WINDOWS`` 0x20000 Flag used to align windows (in items with windows) at the same horizontal position. -``TR_NO_HEADER`` 0x40000 Use this style to hide the columns header. -``TR_VIRTUAL`` 0x80000 `HyperTreeList` will have virtual behaviour. -============================== =========== ================================================== - - -Events Processing -================= - -This class processes the following events: - -============================== ================================================== -Event Name Description -============================== ================================================== -``EVT_LIST_COL_BEGIN_DRAG`` The user started resizing a column - can be vetoed. -``EVT_LIST_COL_CLICK`` A column has been left-clicked. -``EVT_LIST_COL_DRAGGING`` The divider between columns is being dragged. -``EVT_LIST_COL_END_DRAG`` A column has been resized by the user. -``EVT_LIST_COL_RIGHT_CLICK`` A column has been right-clicked. -``EVT_TREE_BEGIN_DRAG`` Begin dragging with the left mouse button. -``EVT_TREE_BEGIN_LABEL_EDIT`` Begin editing a label. This can be prevented by calling `Veto()`. -``EVT_TREE_BEGIN_RDRAG`` Begin dragging with the right mouse button. -``EVT_TREE_DELETE_ITEM`` Delete an item. -``EVT_TREE_END_DRAG`` End dragging with the left or right mouse button. -``EVT_TREE_END_LABEL_EDIT`` End editing a label. This can be prevented by calling `Veto()`. -``EVT_TREE_GET_INFO`` Request information from the application (not implemented in `CustomTreeCtrl`). -``EVT_TREE_ITEM_ACTIVATED`` The item has been activated, i.e. chosen by double clicking it with mouse or from keyboard. -``EVT_TREE_ITEM_CHECKED`` A checkbox or radiobox type item has been checked. -``EVT_TREE_ITEM_CHECKING`` A checkbox or radiobox type item is being checked. -``EVT_TREE_ITEM_COLLAPSED`` The item has been collapsed. -``EVT_TREE_ITEM_COLLAPSING`` The item is being collapsed. This can be prevented by calling `Veto()`. -``EVT_TREE_ITEM_EXPANDED`` The item has been expanded. -``EVT_TREE_ITEM_EXPANDING`` The item is being expanded. This can be prevented by calling `Veto()`. -``EVT_TREE_ITEM_GETTOOLTIP`` The opportunity to set the item tooltip is being given to the application (call `TreeEvent.SetToolTip`). -``EVT_TREE_ITEM_HYPERLINK`` An hyperlink type item has been clicked. -``EVT_TREE_ITEM_MENU`` The context menu for the selected item has been requested, either by a right click or by using the menu key. -``EVT_TREE_ITEM_MIDDLE_CLICK`` The user has clicked the item with the middle mouse button (not implemented in `CustomTreeCtrl`). -``EVT_TREE_ITEM_RIGHT_CLICK`` The user has clicked the item with the right mouse button. -``EVT_TREE_KEY_DOWN`` A key has been pressed. -``EVT_TREE_SEL_CHANGED`` Selection has changed. -``EVT_TREE_SEL_CHANGING`` Selection is changing.
