EVT_ENTER_WINDOW while LeftIsDown()

[Eran Ifrah]

Hi Vaidm,

I commented the entire 'OnLeftDown' function, so its code looks like this:

void wxVerticalTab::OnLeftDown(wxMouseEvent &e)
{
    e.Skip();
}

The OnEnterWindow:
void wxVerticalTab::OnMouseEnterWindow(wxMouseEvent &e)
{
    wxLogMessage(wxT("OnMouseEnterWindow entered"));
    if (e.LeftIsDown()) {
        wxTabContainer *parent =3D dynamic_cast<wxTabContainer*>( GetParent=
()
);
        if (parent) {
            parent->SwapTabs(this);
        }
    }
    e.Skip();
}

the behavior is still the same.
I only get the "OnMouseEnterWindow entered" message when the mouse is not
pressed while entering the window.

I also tried to add code for OnMouseLeaveWindow(), and in it I placed the
following code:

OnMouseLeaveWindow(wxMouseEvent &e)
{
    if(HasCapture()) {
        wxLogMessage(wxT("Releasing mouse"));
        ReleaseMouse();
    }
    e.Skip()
}

Unfortunately, the 'ReleaseMouse()' is never called
