How to implement mouse gesture by qt
-
what I wanna perhaps like this:
when a right mouse button is pressed and we go down and right with a cursor. As in letter ‘L’. Our mouse gesture will close the window.I think Qt already have framework for mouse gesture .see here
http://doc.qt.digia.com/qt/gestures-overview.html
Although I cannot make use of the knowledge there due to a lack of Qt programming experience ,but I still think it can helps us simplify the mouse gesture program design.
please forgive my greedy request ,can you give me an code example ?I googled such gesture examples on Qt4 ,but hard to find one ,so your help will be greatly appreciated !
thanks inadvance !

Hi,
You can take a look at "this":http://qt-project.org/forums/viewthread/18613/ thread, there are some links for tutorials and implementations.
You need to subclass "QGestureRecognizer":http://qt-project.org/doc/qt-5.0/qtwidgets/qgesturerecognizer.html class and create a custom gesture to handle the required effect.
