[Qt-interest] Fwd: how to judge which button click the QTreeWidgetItem?

[lvbing lvbing]

Thanks to all:)

In Qt4,both the left and right button will emit the itemClicked signal after
clicked. and the signal itemClicked is emited after the mouseReleaseEvent.

so I do it:
class MTreeWdiget : public QTreeWidget
{
publict:
    ....
    void mouseReleaseEvent(QMouseEvent* event);
}

in the function mouseReleaseEvent,I can judget if the left or right button
clicked,so my problem was be resolved.

thanks for all.

PS:
1 qApp->buttons() will return 0 when emit the itemClicked.
