Arabic issue #26: The origin in RTL layout should be positioned at the right edge of the window

[Munzir Taha]

Qt Version: qt-x11-opensource-4.0.0-b2-snapshot-20050302
System: Linux localhost 2.6.10-1mdk i686 AMD Athlon(tm) 64 Processor 3200+

CODE:
qPushButton->setGeometry(0, 0, 75, 100);

PROBLEM:
After an application has set RTL layout, the origin should be positioned at 
the right edge of the window or device, and the number representing the 
horizontal coordinate should increase as you move left.

No. This would break a huge amount of code out there. 

Qt's coordinate system doesn't change when the layout direction changes. If we 
did so, you could be sure that almost everything would break and no 
application developer would manage to write apps that work both LTR and RTL.

The solution to this is to not hardcode geometries of subwidgets but use 
layouts which do all the work for you. If you hardcode the position you get 
what you ask for.

Surely, you know better than me and M$ but this is why I am telling you this.

or maybe I have misunderstood their point of coordinate transformation?

Lars! Will you please tell me the easiest way of how this should be done? I 
mean Something like a Dialog box or any widget that would appear in the 
top-left corner on LTR and on top-right corner in RTL.
