That is not really what I am looking for, since my target platform should include Windows XP, also it would be nice if it ran on other platforms. On the other hand I made a quite exciting discovery that window type Qt::ToolTip is shown even when "show desktop" is clicked, but the problem is that it implies always-on-top. Weird is that with: QWidget(0, Qt::ToolTip | Qt::FramelessWindowHint) the widget shows correctly on top, however with: QWidget(0, Qt::ToolTip | Qt::FramelessWindowHint | Qt::WindowStaysOnBottomHint) it shows on bottom (correctly displaying warning "Incompatible window flags: the window can't be on top and on bottom at the same time") and hiding when "show desktop", which seems to be in contradiction with: http://qt.gitorious.org/qt/qt/blobs/092cd760d5fddf9640a310214fe01929f0fff3a8/src/gui/kernel/qwidget_win.cpp#line441 (git tag of Qt 4.7.4 which is what I use). Any insight and suggestion are welcome.
