Hello all,
I have a custom container widget (derived from Gtk::Container) which is
somewhat similar to a toolbar. I am declaring the widget as windowless in
the class constructor by *set_flags(Gtk::NO_WINDOW)*. Later in ::on_realize
of my class I do the following.
void CInlineMenu::on_realize()
{
GdkWindowAttr stWndAttrib;
Gtk::Allocation obAlloc;
//Call base class
Gtk::Container::on_realize();
if(!m_refWnd)
{
//Get size allocation
obAlloc = get_allocation();
//Set window attributes
stWndAttrib.x = obAlloc.get_x();
stWndAttrib.y = obAlloc.get_y();
stWndAttrib.width = obAlloc.get_width();
stWndAttrib.height = obAlloc.get_height();
stWndAttrib.event_mask = Gdk::EXPOSURE_MASK;
stWndAttrib.window_type = GDK_WINDOW_CHILD;
stWndAttrib.wclass = GDK_INPUT_OUTPUT;
stWndAttrib.type_hint = GDK_WINDOW_TYPE_HINT_DOCK;
//Create a window
m_refWnd = Gdk::Window::create(get_window(), &stWndAttrib, GDK_WA_X
| GDK_WA_Y);
//unset_flags(Gtk::NO_WINDOW);
//set_window(m_refWnd);
m_refWnd->set_user_data(gobj());
}
}
Within this container I will be having multiple windowed widgets like
buttons. Now when I run my application the child widgets are visible but
the drawing what I do within the *on_expose_event* override of my class is
not appearing on screen, which I believe is because I created my widget
window-less.
Now the million dollar question is how to draw something from this class. Is
it even possible or do I need to reconsider I *realize* my widget?
