default contextMenu

[Naveen]

This may sound weird ...but
Could anyone please give me a code which has a widget(a simple widget which draws a rectangle in a QHBox) and this widget should implement a DefaultContextMenu and could u please say what this "contextMenuEvent()" is and what are the options this DefaultContextMenu gives it is like "Close","Maximise","Minimise","Restore"


Thanks In Advance

There is no such thing as "default context menu" which would contain some default menu items. You need to construct the context menu by yourself. By changing the property QWidget::contextMenuPolicy changes the way context menu can be handled.

The default value of this property is Qt:efaultContextMenu, which means the contextMenuEvent() handler is called. Other values are Qt::NoContextMenu, Qt::ActionsContextMenu, and Qt::CustomContextMenu. With Qt::CustomContextMenu, the signal customContextMenuRequested() is emitted.

So one way to popup a context menu is to override your widget's context menu event handler. The example below shows a way to show a context menu. Most probably you don't want to construct the menu each time it needs to be shown, rather construct it elsewhere and only show it here.

void YourWidget::contextMenuEvent(QContextMenuEvent* e)
{
	QMenu menu(this);
	QAction* act = menu.addAction("Something");
	menu.exec(e->globalPos());
}

void YourWidget::contextMenuEvent(QContextMenuEvent* e)
{
	QMenu menu(this);
	QAction* act = menu.addAction("Something");
	menu.exec(e->globalPos());
}
