How to change the cursor to hand when enter to a window?

[He HongFu]

Hi,

I would like the cursor to change to a hand when the mouse is over a
window. But the window always be arrow cursor.

Here is the code segment:

EVT_MOTION (ListMenu::onMouseMotion)

ListMenu::onMouseMotion (wxEvent& event) {
if (HitTest (event.GetPosition(), _expandBtnRect) == false) {
::wxSetCursor (wxCursor (wxCURSOR_ARROW));
return;
}

::wxSetCursor (wxCursor (wxCURSOR_HAND));
}

Thanks in advance.

Or, maybe you want a more dynamic behavior, like this

/** Called when the mouse enters the view
*/
void MyView::OnMouseEnter(wxMouseEvent& WXUNUSED(event))
{ if(TheCanvas)
TheCanvas->SetCursor(*wxCROSS_CURSOR);
}

/** Called when the mouse exits the view
*/
void MyView::OnMouseExit(wxMouseEvent& WXUNUSED(event))
{
if(TheCanvas)
TheCanvas->SetCursor(*wxSTANDARD_CURSOR);
}

Hi, Paulo,

Thanks very much. We have solved this problem. Because we forget add wx.rc into our resource script.

Best Regards!
