QMdiArea::tileSubWindows() always places widgets in ActivationHistoryOrder in SubWindowView mode

alex_malyu

found in Qt 4.8 ( not sure about 5.*)

check is simple and can be demonstrated on mdi example :

create 2 subwindows
click Tile menu command
click inactive subwindow to activate it
click Tile menu command
result unexpected: subwindows switch positions

I created my own example to doublecheck with following lines

@ ui.mdiArea->setViewMode( QMdiArea::SubWindowView);
ui.mdiArea->setActivationOrder( QMdiArea::CreationOrder );
@

result is the same.

Work around which also demonstrates the problem:
instead of ui.mdiArea->tileSubWindows()
call custom slot with code below:

@ QMdiSubWindow *a = ui.mdiArea->activeSubWindow();
QList<QMdiSubWindow *> list = ui.mdiArea->subWindowList( ui.mdiArea->activationOrder( ) );
for( int i=0; i< list.count(); i++ )
{
ui.mdiArea->setActiveSubWindow( list[i] );
}

ui.mdiArea->tileSubWindows();
ui.mdiArea->setActiveSubWindow( a );
@
result - subwindows are tiled in activationOrder( )

I installed Qt 5. The same bug is present.
Guess I will have to report the bug.
