-
- QxtTabWidget provides some convenience for handling tab specific context menus.
-
- Example usage:
- \code
- QxtTabWidget* tabWidget = new QxtTabWidget();
- tabWidget->addTab(tab0, "1");
- tabWidget->addTab(tab1, "2");
-
- QList<QAction*> actions0;
- actions0 << new QAction("Quisque", tab0) << new QAction("Aenean", tab0);
- QList<QAction*> actions1;
- actions1 << new QAction("Phasellus", tab1) << new QAction("Maecenas", tab1);
-
- tabWidget->setTabContextMenuPolicy(Qt::ActionsContextMenu);
- tabWidget->addTabActions(0, actions0);
- tabWidget->addTabActions(1, actions1);
