wx.TreeCtrl

Inheritance diagram for wx.TreeCtrl:

Description

A tree control presents information as a hierarchy, with items that may be expanded to show further items. Items in a tree control are referenced by wx.TreeItemId handles, which may be tested for validity by calling wx.TreeItemId.IsOk.

To intercept events from a tree control, use the event table macros described in wx.TreeEvent.

Note

Win32 note: wx.TreeCtrl class uses the standard common treeview control under Win32 implemented in the system library comctl32.dll. Some versions of this library are known to have bugs with handling the tree control colours: the usual symptom is that the expanded items leave black (or otherwise incorrectly coloured) background behind them, especially for the controls using non-default background colour. The recommended solution is to upgrade the comctl32.dll to a newer version: see http://www.microsoft.com/downloads/release.asp?ReleaseID=11916.

Window Styles

Window Style	Description
wx.TR_EDIT_LABELS	Use this style if you wish the user to be able to edit labels in the tree control.
wx.TR_NO_BUTTONS	For convenience to document that no buttons are to be drawn.
wx.TR_HAS_BUTTONS	Use this style to show + and - buttons to the left of parent items.
wx.TR_NO_LINES	Use this style to hide vertical level connectors.
wx.TR_FULL_ROW_HIGHLIGHT	Use this style to have the background colour and the selection highlight extend over the entire horizontal row of the tree control window. (This flag is ignored under Windows unless you specify wx.TR_NO_LINES as well.)
wx.TR_LINES_AT_ROOT	Use this style to show lines between root nodes. Only applicable if wx.TR_HIDE_ROOT is set and wx.TR_NO_LINES is not set.
wx.TR_HIDE_ROOT	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.
wx.TR_ROW_LINES	Use this style to draw a contrasting border between displayed rows.
wx.TR_HAS_VARIABLE_ROW_HEIGHT	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. Generic only.
wx.TR_SINGLE	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.
wx.TR_MULTIPLE	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.
wx.TR_EXTENDED	Use this style to allow disjoint items to be selected. (Only partially implemented; may not work in all cases.)
wx.TR_DEFAULT_STYLE	The set of flags that are closest to the defaults for the native control for a particular toolkit.

Class API

Methods

__init__(parent, id=-1, pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.TR_DEFAULT_STYLE, validator=wx.DefaultValidator, name=wx.TreeCtrlNameStr)

• validator (wx.Validator)
• name (string)

Returns:

---

AddRoot(text, image=-1, selImage=-1, data=None)

Adds the root node to the tree, returning the new item.

The image and selImage parameters are an index within the normal image list specifying the image to use for unselected and selected items, respectively. If image > -1 and selImage is -1, the same image is used for both selected and unselected items.

Parameters:

• text (string)
• image (int)
• selImage (int)
• data (PyObject)

Returns:

wx.TreeItemId

---

AppendItem(parent, text, image=-1, selImage=-1, data=None)

Appends an item to the end of the branch identified by parent, return a new item id.

The image and selImage parameters are an index within the normal image list specifying the image to use for unselected and selected items, respectively. If image > -1 and selImage is -1, the same image is used for both selected and unselected items.

Parameters:

• parent (wx.TreeItemId)
• text (string)
• image (int)
• selImage (int)
• data (PyObject)

Returns:

wx.TreeItemId

---

AssignImageList(imageList)

Sets the normal image list. Image list assigned with this method will be automatically deleted by wx.TreeCtrl as appropriate (i.e. it takes ownership of the list).

Parameters:

• imageList (wx.ImageList)

See also

SetImageList.

---

AssignStateImageList(imageList)

Sets the state image list. Image list assigned with this method will be automatically deleted by wx.TreeCtrl as appropriate (i.e. it takes ownership of the list).

Parameters:

• imageList (wx.ImageList)

See also

SetStateImageList.

---

Collapse(item)

Collapses the given item.

Parameters:

• item (wx.TreeItemId)

---

CollapseAll()

Collapses the root item.

See also

ExpandAll

---

CollapseAllChildren(item)

Collapses this item and all of its children, recursively.

Parameters:

• item (wx.TreeItemId)

See also

ExpandAllChildren

---

CollapseAndReset(item)

Collapses the given item and removes all children.

Parameters:

• item (wx.TreeItemId)

---

Delete(item)

Deletes the specified item. A wx.EVT_TREE_DELETE_ITEM event will be generated. This function may cause a subsequent call to GetNextChild to fail.

Parameters:

• item (wx.TreeItemId)

---

DeleteAllItems()

Deletes all items in the control.

Note

Note that this may not generate wx.EVT_TREE_DELETE_ITEM events under some Windows versions although normally such event is generated for each removed item.

---

DeleteChildren(item)

Deletes all children of the given item (but not the item itself).

If you have called SetItemHasChildren, you may need to call it again since DeleteChildren does not automatically clear the setting.

Parameters:

• item (wx.TreeItemId)

Note

Note that this will not generate any events unlike Delete method.

---

EditLabel(item)

Starts editing the label of the given item. This function generates a wx.EVT_TREE_BEGIN_LABEL_EDIT event which can be vetoed so that no text control will appear for in-place editing.

If the user changed the label (i.e. s/he does not press ESC or leave the text control without changes, a wx.EVT_TREE_END_LABEL_EDIT event will be sent which can be vetoed as well.

Parameters:

• item (wx.TreeItemId)

See also

EndEditLabel, wx.TreeEvent

---

EndEditLabel(cancelEdit)

Ends label editing. If cancelEdit is True, the edit will be cancelled.

Parameters:

• cancelEdit (bool)

Note

This function is currently supported under Windows only.

See also

wx.TreeCtrl.EditLabel

Parameters:

• item (wx.TreeItemId)
• textOnly (bool)

Returns:

wx.Rect

Note

Notice that the rectangle coordinates are logical, not physical ones. So, for example, the x coordinate may be negative if the tree has a horizontal scrollbar and its position is not 0.

---

GetNextChild(item, cookie)

Returns the next child; call GetFirstChild for the first child.

For this enumeration function you must pass in a cookie parameter which is opaque for the application but is necessary for the library to make these functions reentrant (i.e. allow more than one enumeration on one and the same object simultaneously). The cookie returned by GetFirstChild and passed to GetNextChild should be the same.
