I need to catch the mouse-motion-event on the wxTreeCtrl to know when I have to destroy the wxTipWindow.
But it doesn't work. I can catch the mouse-motion-event to know when I need to create a wxTipWindow.
But if the window is created the event-handling-methode for mouse-motion is not executed until the wxTipWindow is killed (by a timer).
Catching the mouse-motion-event in the TipWindow itself doesn't work, too. Setting the focus back to the TreeCtrl after creating the TipWindow doesn't work, too.
This is the mouse-motion handler methode in the TreeCtrl.
Code: Select all
void BFBackupTree::OnMouseMotion (wxMouseEvent& rEvent)
{
BFSound::Info();
// delete the current tip window because of mouse movement
BFTipWindow::DeleteTipWindow();
// mouse position
wxPoint point = rEvent.GetLogicalPosition(wxWindowDC(this));
// get the item id under the mouse
int iFlags;
wxTreeItemId id = HitTest(point, iFlags);
// is it an item and not the right blank area
if ( id.IsOk() && !(iFlags & wxTREE_HITTEST_ONITEMRIGHT) )
BFTipWindow::CreateTipWindow(this, "TIP\nTIP2");
}This is the BFTipWindow itself.
