Balloon-tips with Qt

Question

In my Qt application, I'd like to use balloons/balloon-tips as shown in the Windows user experience guide (not the system tray balloons).

Is this supported by Qt? I haven't found anything. Is there an Open Source library out there for this (Qxt does not have it)? What's the best way to create that myself?

Answer 1

Search for QBalloonTip class (in Qt documentation (doxygen reference) and code base, look how it is implemented, and use similar technique.

Answer 2

You can use QBalloonTip which is an internal class defined in :

• Qt 5:

  QtDir/Src/qtbase/src/widgets/util/qsystemtrayicon_p.h

• Qt 4:

  QtDir/src/gui/utils/util/qsystemtrayicon_p.h

QBalloonTip inherits QWidget and it is implemented in qsystemtrayicon.cpp at the same directory. It has the following method to show a balloon tip:

void QBalloonTip::balloon(const QPoint& pos, int msecs, bool showArrow)

You can modify the source code of this class to have your desired balloon tip.
