Re: [Interest] Creating Desktop Widgets (aka Desklets) in Qt
Sent: Wednesday, 25 July 2012 1:35 AM Hi, I am tasked in creating desktop widgets (aka desklets, stuff like system monitors, clocks, etc) in Qt, the target platform is Windows. So far I managed to create a frameless window which stays on bottom and isn't shown on taskbar by following window flags: Qt::SubWindow | Qt::FramelessWindowHint | Qt::WindowStaysOnBottomHint However no matter what I tried, I didn't manage to keep the desklets shown when user presses the Windows show desktop icon. Does anybody know a way? The desklet class is a subclass of QWidget, using QDesktopWidget doesn't help the situation at all (and from docs it's clear it is for different purpose). I tried intercepting events which make the desklet hide, but it seems this is a special case not handled by any event... I tried all prospective window flags, even those more crazy in the aspect. But all to no avail... They are called gadgets on Windows. From a quick read, I doubt Qt is any use: http://msdn.microsoft.com/en-us/library/windows/desktop/bb456468%28v=vs.85%29.aspx Regards, Tony 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. signature.asc Description: OpenPGP digital signature ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
