wxTreeListCtrl - How to receive mouse events

[m.a.k.]

Hi.

I'm using the wxTreeListCtrl (http://wxcode.sourceforge.net/components/treelistctrl/).

Everything works fine except of one thing: I don't know how to receive simple mouse events with this control...

I just want to receive an event when the user clicks on an item, but when I try to set an event handler with

Code: Select all

m_treelist->Connect(ID_TREELISTCTRL, wxEVT_LEFT_DOWN, wxMouseEventHandler(MainWindow::OnLeftDown), NULL, this);

and I click somewhere on the tree list control it just happens - nothing... ;(

The same for all other mouse events like mouse move, right click etc.

Hope someone could help me with this.

Regards,
m.a.k.

Hi,

Nobody who knows the answer seems to be going to respond, so...

Without looking at the source I can't be sure, but I suspect that a wxTreeListCtrl is a composite control of a treectrl and a listctrl. An example where I know this is true is wxGenericDirCtrl, which contains a member wxTreeCtrl.

To get events using Connect() from a wxGenericDirCtrl, you can't use a pointer to the wxGenericDirCtrl; you have to get one to the underlying treectrl (using wxGenericDirCtrl::GetTreeCtrl). I suspect you will need to do something similar, Connect()ing to the underlying listctrl.

I suggest you have a look at the source-code.

To receive events it is also necessary to have an EVENT_TABLE or dynamicly connect the event to a function.

example:

BEGIN_EVENT_TABLE(LayoutTreeCtrl, wxTreeCtrl)
EVT_TREE_BEGIN_RDRAG(ID_LAYOUT_TREE, OnBeginRDrag) EVT_TREE_ITEM_ACTIVATED(ID_LAYOUT_TREE,OnSectionSelection)
END_EVENT_TABLE( )
