Detailed Description
A list event holds information about events associated with wxListCtrl objects.
Events using this class
The following event handler macros redirect the events to member function handlers 'func' with prototypes like:
void handlerFuncName(wxListEvent& event)
Event macros:
- EVT_LIST_BEGIN_DRAG(id, func):Begin dragging with the left mouse button.
- EVT_LIST_BEGIN_RDRAG(id, func):Begin dragging with the right mouse button.
- EVT_LIST_BEGIN_LABEL_EDIT(id, func):Begin editing a label. This can be prevented by calling Veto().
- EVT_LIST_END_LABEL_EDIT(id, func):Finish editing a label. This can be prevented by calling Veto().
- EVT_LIST_DELETE_ITEM(id, func):Delete an item.
- EVT_LIST_DELETE_ALL_ITEMS(id, func):Delete all items.
- EVT_LIST_ITEM_SELECTED(id, func):The item has been selected.
- EVT_LIST_ITEM_DESELECTED(id, func):The item has been deselected.
- EVT_LIST_ITEM_ACTIVATED(id, func):The item has been activated (ENTER or double click).
- EVT_LIST_ITEM_FOCUSED(id, func):The currently focused item has changed.
- EVT_LIST_ITEM_MIDDLE_CLICK(id, func):The middle mouse button has been clicked on an item.
- EVT_LIST_ITEM_RIGHT_CLICK(id, func):The right mouse button has been clicked on an item.
- EVT_LIST_KEY_DOWN(id, func):A key has been pressed. GetIndex() may be -1 if no item is selected.
- EVT_LIST_INSERT_ITEM(id, func):An item has been inserted.
- EVT_LIST_COL_CLICK(id, func):A column (m_col) has been left-clicked.
- EVT_LIST_COL_RIGHT_CLICK(id, func):A column (m_col) (which can be -1 if the click occurred outside any column) has been right-clicked.
- EVT_LIST_COL_BEGIN_DRAG(id, func):The user started resizing a column - can be vetoed.
- EVT_LIST_COL_DRAGGING(id, func):The divider between columns is being dragged.
- EVT_LIST_COL_END_DRAG(id, func):A column has been resized by the user.
- EVT_LIST_CACHE_HINT(id, func):Prepare cache for a virtual list control

This method only makes sense for EVT_LIST_END_LABEL_EDIT message and returns true if it the label editing has been cancelled by the user (GetLabel() returns an empty string in this case but it doesn't allow the application to distinguish between really cancelling the edit and the admittedly rare case when the user wants to rename it to an empty string).
