wxGrid and EVT_CONTEXT_MENU

[silverstorm82]

Hello folks,

did anyone got wxGrid to respond to the EVT_CONTEXT_MENU event-handler? I am using a derived class from wxGrid, declared an event table and used EVT_CONTEXT_MENU in it but the handler function is not called:

Code: Select all

class CMyGrid : public wxGrid
{
...
protected:
    void OnContextMenu(wxContextMenuEvent& event);
    DECLARE_EVENT_TABLE();
...
};



BEGIN_EVENT_TABLE(CMyGrid, wxGrid)
    EVT_CONTEXT_MENU(OnContextMenu);
END_EVENT_TABLE



void CMyGrid::OnContextMenu(wxContextMenuEvent& event)
{
    wxMessageBox(wxT("TEST"));
}

"TEST" is never displayed when clicking right on the grid.

Any ideas about this? There must be an error somewhere but I was not able to locate it I also checked this forum but didn't find a solution for the problem.

Thanks in advance,
Jens

I think this is because the events are "eaten" by the wxGrid's components, while wxGrid emits its own events for most of the corresponding "normal" ones. Among the emitted events there is none for menu, but IIRC using wxEVT_GRID_CELL_RIGHT_CLICK and wxEVT_GRID_LABEL_RIGHT_CLICK will work around that limitation. It's not perfect as it will not work for the MSW's context menu button, but may be good enough.

Hi,

that was my first approach but I thought there may be another one as I read in the documentation that handling a wxContextMenuEvent is the better approach as there are different ways of how context menus are handled on the various platforms.
