I don't think that will work because the containing view will draw behind the contained views. You can try making a view that's a sibling of both the button and the tab view and ordered on top of both. Another approach would be to make a mostly-transparent overlay window to draw the arrow. Make sure it ignores mouse events so clicks on the opaque parts go through. Set it as a child window of the window containing the buttons and tab view, so it moves with it. If the underlying window is resizable or changes its layout, you'll need to take care to keep the position of the arrow synchronized with the other controls. (That's true of any approach you take, of course.)
