List of all members.


Detailed 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 wxTreeItemId handles, which may be tested for validity by calling wxTreeItemId::IsOk().

A similar control with a fully native implemtation for GTK+ and OS X as well is wxDataViewTreeCtrl.

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

Styles:

Events:

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxTreeEvent& event)

Event macros:
See also Window Styles.

Win32 notes:

wxTreeCtrl 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/details.aspx?familyid=cb2cf3a2-8025-4e8f-8511-9b476a8d35d2

Destructor, destroying the tree control.


Member Function Documentation

virtual wxTreeItemId wxTreeCtrl::AddRoot ( const wxString text,
int  image = -1,
int  selImage = -1,
wxTreeItemData data = NULL 
) [virtual]

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.

wxTreeItemId wxTreeCtrl::AppendItem ( const wxTreeItemId parent,
const wxString text,
int  image = -1,
int  selImage = -1,
wxTreeItemData data = NULL 
)

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.

void wxTreeCtrl::AssignButtonsImageList ( wxImageList imageList  ) 

Sets the buttons image list. The button images assigned with this method will be automatically deleted by wxTreeCtrl as appropriate (i.e. it takes ownership of the list).

Setting or assigning the button image list enables the display of image buttons. Once enabled, the only way to disable the display of button images is to set the button image list to NULL.

This function is only available in the generic version.

See also:
SetButtonsImageList().

void wxTreeCtrl::AssignImageList ( wxImageList imageList  ) 

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

See also:
SetImageList().

void wxTreeCtrl::AssignStateImageList ( wxImageList imageList  ) 

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

See also:
SetStateImageList().

virtual void wxTreeCtrl::Collapse ( const wxTreeItemId item  )  [virtual]

Collapses the given item.

void wxTreeCtrl::CollapseAll (  ) 

Collapses the root item.

See also:
ExpandAll()

void wxTreeCtrl::CollapseAllChildren ( const wxTreeItemId item  ) 

Collapses this item and all of its children, recursively.

See also:
ExpandAllChildren()

virtual void wxTreeCtrl::CollapseAndReset ( const wxTreeItemId item  )  [virtual]

Collapses the given item and removes all children.

bool wxTreeCtrl::Create ( wxWindow parent,
wxWindowID  id,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = wxTR_HAS_BUTTONS,
const wxValidator validator = wxDefaultValidator,
const wxString name = "treeCtrl" 
)

Creates the tree control. See wxTreeCtrl::wxTreeCtrl() for further details.

virtual void wxTreeCtrl::Delete ( const wxTreeItemId item  )  [virtual]

Deletes the specified item. A EVT_TREE_DELETE_ITEM() event will be generated.

This function may cause a subsequent call to GetNextChild() to fail.

virtual void wxTreeCtrl::DeleteAllItems (  )  [virtual]

Deletes all items in the control. Note that this may not generate EVT_TREE_DELETE_ITEM() events under some Windows versions although normally such event is generated for each removed item.

virtual void wxTreeCtrl::DeleteChildren ( const wxTreeItemId item  )  [virtual]

Deletes all children of the given item (but not the item itself). Note that this will not generate any events unlike Delete() method.

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

void wxTreeCtrl::EditLabel ( const wxTreeItemId item  ) 

Starts editing the label of the given item. This function generates a 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 EVT_TREE_END_LABEL_EDIT() event will be sent which can be vetoed as well.

See also:
EndEditLabel(), wxTreeEvent

void wxTreeCtrl::EndEditLabel ( bool  cancelEdit  ) 

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

Note:
This function is currently supported under Windows only.
See also:
EditLabel()

virtual void wxTreeCtrl::EnsureVisible ( const wxTreeItemId item  )  [virtual]

Scrolls and/or expands items to ensure that the given item is visible.

virtual void wxTreeCtrl::Expand ( const wxTreeItemId item  )  [virtual]

Expands the given item.

void wxTreeCtrl::ExpandAll (  ) 

Expands all items in the tree.

void wxTreeCtrl::ExpandAllChildren ( const wxTreeItemId item  ) 

Expands the given item and all its children recursively.

bool wxTreeCtrl::GetBoundingRect ( const wxTreeItemId item,
wxRect rect,
bool  textOnly = false 
) const

Retrieves the rectangle bounding the item. If textOnly is true, only the rectangle around the item's label will be returned, otherwise the item's image is also taken into account.

The return value is true if the rectangle was successfully retrieved or false if it was not (in this case rect is not changed) -- for example, if the item is currently invisible.

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.

wxPython Note: The wxPython version of this method requires only the item and textOnly parameters. The return value is either a wxRect object or None.

wxImageList* wxTreeCtrl::GetButtonsImageList (  )  const

Returns the buttons image list (from which application-defined button images are taken).

This function is only available in the generic version.

unsigned int wxTreeCtrl::GetChildrenCount ( const wxTreeItemId item,
bool  recursively = true 
) const

Returns the number of items in the branch. If recursively is true, returns the total number of descendants, otherwise only one level of children is counted.

virtual unsigned int wxTreeCtrl::GetCount (  )  const [virtual]

Returns the number of items in the control.

virtual wxTextCtrl* wxTreeCtrl::GetEditControl (  )  const [virtual]

Returns the edit control being currently used to edit a label. Returns NULL if no label is being edited.

Note:
This is currently only implemented for wxMSW.

wxTreeItemId wxTreeCtrl::GetFirstChild ( const wxTreeItemId item,
wxTreeItemIdValue &  cookie 
) const

Returns the first child; call GetNextChild() for the next 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 passed to GetFirstChild() and GetNextChild() should be the same variable.

Returns an invalid tree item (i.e. wxTreeItemId::IsOk() returns false) if there are no further children.

wxPython Note: In wxPython the returned wxTreeItemId and the new cookie value are both returned as a tuple containing the two values.

See also:
GetNextChild(), GetNextSibling()

virtual wxTreeItemId wxTreeCtrl::GetFirstVisibleItem (  )  const [virtual]

Returns the first visible item.

wxImageList* wxTreeCtrl::GetImageList (  )  const

virtual wxFont wxTreeCtrl::GetItemFont ( const wxTreeItemId item  )  const [virtual]

Returns the font of the item label.

int wxTreeCtrl::GetItemImage ( const wxTreeItemId item,
wxTreeItemIcon  which = wxTreeItemIcon_Normal 
) const

Gets the specified item image. The value of which may be:

  • wxTreeItemIcon_Normal: to get the normal item image.
  • wxTreeItemIcon_Selected: to get the selected item image (i.e. the image which is shown when the item is currently selected).
  • wxTreeItemIcon_Expanded: to get the expanded image (this only makes sense for items which have children - then this image is shown when the item is expanded and the normal image is shown when it is collapsed).
  • wxTreeItemIcon_SelectedExpanded: to get the selected expanded image (which is shown when an expanded item is currently selected).

virtual wxTreeItemId wxTreeCtrl::GetItemParent ( const wxTreeItemId item  )  const [virtual]

Returns the item's parent.

int wxTreeCtrl::GetItemSelectedImage ( const wxTreeItemId item  )  const

Gets the selected item image (this function is obsolete, use GetItemImage( item, wxTreeItemIcon_Selected) instead).

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 passed to GetFirstChild() and GetNextChild() should be the same.

Returns an invalid tree item if there are no further children.

wxPython Note: In wxPython the returned wxTreeItemId and the new cookie value are both returned as a tuple containing the two values.

See also:
GetFirstChild()

const wxTreeItemId previous,
const wxString text,
int  image = -1,
int  selImage = -1,
wxTreeItemData data = NULL 
)

Inserts an item after a given one (previous).

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.

wxTreeItemId wxTreeCtrl::InsertItem ( const wxTreeItemId parent,
size_t  before,

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.

wxPython Note: In wxPython, this form of this method is called InsertItemBefore().

virtual bool wxTreeCtrl::IsBold ( const wxTreeItemId item  )  const [virtual]

Returns true if the given item is in bold state.

See also:
SetItemBold()

bool wxTreeCtrl::IsEmpty (  )  const

Returns true if the control is empty (i.e. has no items, even no root one).

virtual bool wxTreeCtrl::IsExpanded ( const wxTreeItemId item  )  const [virtual]

Returns true if the item is expanded (only makes sense if it has children).

virtual bool wxTreeCtrl::IsSelected ( const wxTreeItemId item  )  const [virtual]

Returns true if the item is selected.

virtual bool wxTreeCtrl::IsVisible ( const wxTreeItemId item  )  const [virtual]

Returns true if the item is visible on the screen.

virtual bool wxTreeCtrl::ItemHasChildren ( const wxTreeItemId item  )  const [virtual]

Returns true if the item has children.

int wxTreeCtrl::OnCompareItems ( const wxTreeItemId item1,
const wxTreeItemId item2 
)

Override this function in the derived class to change the sort order of the items in the tree control. The function should return a negative, zero or positive value if the first item is less than, equal to or greater than the second one.

Please note that you must use wxRTTI macros DECLARE_DYNAMIC_CLASS() and IMPLEMENT_DYNAMIC_CLASS() if you override this function because otherwise the base class considers that it is not overridden and uses the default comparison, i.e. sorts the items alphabetically, which allows it optimize away the calls to the virtual function completely.

See also:
SortChildren()

wxTreeItemId wxTreeCtrl::PrependItem ( const wxTreeItemId parent,
const wxString text,
int  image = -1,
int  selImage = -1,
wxTreeItemData data = NULL 
)

Appends an item as the first child of 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.

virtual void wxTreeCtrl::ScrollTo ( const wxTreeItemId item  )  [virtual]

Scrolls the specified item into view.

virtual void wxTreeCtrl::SelectItem ( const wxTreeItemId item,
bool  select = true 
) [virtual]

Selects the given item. In multiple selection controls, can be also used to deselect a currently selected item if the value of select is false.

void wxTreeCtrl::SetButtonsImageList ( wxImageList imageList  ) 

Sets the buttons image list (from which application-defined button images are taken).

The button images assigned with this method will not be deleted by wxTreeCtrl's destructor, you must delete it yourself. Setting or assigning the button image list enables the display of image buttons. Once enabled, the only way to disable the display of button images is to set the button image list to NULL.

Note:
This function is only available in the generic version.
See also:
AssignButtonsImageList().

virtual void wxTreeCtrl::SetImageList ( wxImageList imageList  )  [virtual]

Sets the normal image list. The image list assigned with this method will not be deleted by wxTreeCtrl's destructor, you must delete it yourself.

See also:
AssignImageList().

Sets the indentation for the tree control.

void wxTreeCtrl::SetItemBackgroundColour ( const wxTreeItemId item,
const wxColour col 
)

Sets the colour of the item's background.

virtual void wxTreeCtrl::SetItemBold ( const wxTreeItemId item,
bool  bold = true 
) [virtual]

Makes item appear in bold font if bold parameter is true or resets it to the normal state.

See also:
IsBold()

virtual void wxTreeCtrl::SetItemData ( const wxTreeItemId item,
wxTreeItemData data 
) [virtual]

Sets the item client data.

wxPython Note:

  • SetPyData( item, obj): Associate the given Python Object with the wxTreeItemData for the given item Id.

void wxTreeCtrl::SetItemDropHighlight ( const wxTreeItemId item,
bool  highlight = true 
)

Gives the item the visual feedback for Drag'n'Drop actions, which is useful if something is dragged from the outside onto the tree control (as opposed to a DnD operation within the tree control, which already is implemented internally).

virtual void wxTreeCtrl::SetItemFont ( const wxTreeItemId item,
const wxFont font 
) [virtual]

Sets the item's font. All items in the tree should have the same height to avoid text clipping, so the fonts height should be the same for all of them, although font attributes may vary.

See also:
SetItemBold()

void wxTreeCtrl::SetItemHasChildren ( const wxTreeItemId item,
bool  hasChildren = true 
)

Force appearance of the button next to the item. This is useful to allow the user to expand the items which don't have any children now, but instead adding them only when needed, thus minimizing memory usage and loading time.

void wxTreeCtrl::SetItemImage ( const wxTreeItemId &
