Is there a way to cheat the maemo window manager to force the "last stacked window" button appear and be clickable without really creating a stacked widget? (for example by doing some evil X11 calls)

So a application using QGraphicsView for all interaction won't need to run in fullscreen and provide its own back buttons.

same pb here : a qt program in fullscreen with maemo stacked windows are graphically bugged so i needed to do it a qstacekdwidget and use my own titlebar and back buttons and home button (with dbus calls)

but it works and give a really consistency to the apps so where is the pb ?

AFAIK you have to set the right Xatoms on your application. The window manger will pick those up and adjust itself accordingly.

Have a look at the HildonStackableWindow class here: http://maemo.gitorious.org/hildon/hi...kable-window.c

After playing around a bit with the Xatoms, there is no way to cheat hildon-desktop without modifying its source. The transition only happens between to real X11 windows and the windows don't even receive a signal except "close" from the wm
