[Gambas-user] Request for new property z-order of the DesktopWindow object

[John Rose]

Unfortunately I'm not able to include a screenshot of this due to size 
constraints of messages here. So I'll describe it as best I can. The 
Temporary window partially covers the Gambas window (i.e. is higher in 
the windows' stacking order), and the Gambas window is physically above 
(i.e. on the screen) the Temporary window. As the Gambas DesktopWindow 
object is returned before the Temporary DesktopWindow object when the 
FindWindow method is invoked in the FMain form's Form_Open event of my 
app: each DesktopWindow returned being stored in an array. Thus, the 
first DesktopWindow in that array (found by coding for the MouseUp event 
in a DrawingArea of the SelectWindow form (called by the FMain form 
which has its Expanded property set to true) - when the user clicks on 
the overlapping area (so that the position of the mouse will be in both 
desktop windows) - will be the Gambas DesktopWindow: this will be the 
selected window. I want the Temporary window to be the selected window 
as it's on top (i.e. higher in the Stacking Order) of the Gambas window; 
currently the Temporary window is selected as evidenced by the Console 
at runtime. Obviously I still want the Gambas window to be the selected 
window when the user clicks on any point in it outside the overlapping 
area. From the user's point of view, this seems to me to be the logical 
behaviour of the app.

I've attached my app. I've started coding in the MouseUp event using a 
Shell command to call xprop in order to determine which window is on 
top. This needs a fair amount of extra coding as the data returned from 
xprop has to evaluated against the windows data (e.g. stacking order 
from xprop versus window positions stored in the array). It seems to me 
that if each DesktopWindow had a z-order property (to determine its 
priority in the windows' stacking order) then this coding would be much 
easier. I think that I vaguely remember a z-order property in VB: but 
this could be wishful thinking!
