Event table macros
To process input from a tree control, use these event handler macros to direct input to member functions that take a wxTreeEvent argument.
| EVT_TREE_BEGIN_DRAG(id, func) | The user has started dragging an item with the left mouse button. The event handler must call wxTreeEvent::Allow() for the drag operation to continue. |
| EVT_TREE_BEGIN_RDRAG(id, func) | The user has started dragging an item with the right mouse button. The event handler must call wxTreeEvent::Allow() for the drag operation to continue. |
| EVT_TREE_BEGIN_LABEL_EDIT(id, func) | Begin editing a label. This can be prevented by calling Veto(). |
| EVT_TREE_END_DRAG(id, func) | The user has released the mouse after dragging an item. |
| EVT_TREE_END_LABEL_EDIT(id, func) | The user has finished editing a label. This can be prevented by calling Veto(). |
| EVT_TREE_DELETE_ITEM(id, func) | A tree item has been deleted. |
| EVT_TREE_ITEM_ACTIVATED(id, func) | An item has been activated (e.g. double clicked). |
| EVT_TREE_ITEM_COLLAPSED(id, func) | The item has been collapsed. |
| EVT_TREE_ITEM_COLLAPSING(id, func) | The item is being collapsed. This can be prevented by calling Veto(). |
| EVT_TREE_ITEM_EXPANDED(id, func) | The item has been expanded. |
| EVT_TREE_ITEM_EXPANDING(id, func) | The item is being expanded. This can be prevented by calling Veto(). |
