Skype-like Desktop Popup Notification in Qt04 Jan 2015
Qt has no popup desktop notification applet by default. As Qt is highly customizable and almost all widgets are inherited from QWidget, so a custom QWidget can be used as desktop popup applet.
A QWidget instance will be shown like any other top-level window. The following flags can be set to make it look like a popup unlike general window.
setWindowFlags( Qt::Window | // Add if popup doesn't show up Qt::FramelessWindowHint | // No window border Qt::WindowDoesNotAcceptFocus | // No focus Qt::WindowStaysOnTopHint // Always on top );
To hide it from appearing in the task manager, call this function inside the constructor.
There it goes. It looks like the following image. I added a label and button to manage the popup from being closed on button press.
