PyQt和上下文菜单 [英] PyQt and context menu
问题描述
我需要在窗口上单击鼠标右键来创建上下文菜单.但是我真的不知道该如何实现.
I need to create a context menu on right clicking at my window. But I really don't know how to achieve that.
是否有任何小部件,或者我必须从头开始创建它?
Are there any widgets for that, or I have to create it from the beginning?
编程语言:Python
图形库:Qt(PyQt)
Programming language: Python
Graphical lib: Qt (PyQt)
推荐答案
我不能说python,但是在C ++中相当简单.
I can't speak for python, but it's fairly easy in C++.
在创建窗口小部件后首先设置策略:
first after creating the widget you set the policy:
w->setContextMenuPolicy(Qt::CustomContextMenu);
然后将上下文菜单事件连接到插槽:
then you connect the context menu event to a slot:
connect(w, SIGNAL(customContextMenuRequested(const QPoint &)), this, SLOT(ctxMenu(const QPoint &)));
最后,您实现广告位:
void A::ctxMenu(const QPoint &pos) {
QMenu *menu = new QMenu;
menu->addAction(tr("Test Item"), this, SLOT(test_slot()));
menu->exec(w->mapToGlobal(pos));
}
这就是您在c ++中的操作方式,在python API中应该没什么不同.
that's how you do it in c++ , shouldn't be too different in the python API.
编辑:在google上浏览后,这是我的python示例示例的设置部分:
after looking around on google, here's the setup portion of my example in python:
self.w = QWhatever();
self.w.setContextMenuPolicy(Qt.CustomContextMenu)
self.connect(self.w,SIGNAL('customContextMenuRequested(QPoint)'), self.ctxMenu)
