在PySide中添加上下文QMenu以左键单击按钮

Question

我想添加上下文菜单左键点击鼠标按钮按在emailbtn

from PySide import QtCore,QtGui
import sys
class ToolBarUI(QtGui.QWidget):
    def __init__(self,*args,**kwargs):
        super(ToolBarUI,self).__init__(*args,**kwargs)
        self.createActions()
        self.floatingToolBar()
        pass
    def sizeHint(self):
        return QtCore.QSize(65,45)
    def buttons(self):
        x,y=15,35
        self.btnVLay=QtGui.QVBoxLayout(self)
        self.setLayout(self.btnVLay)
        self.btnVLay.setContentsMargins(0,0,0,0)
        self.incSavbtn=QtGui.QPushButton("Save")
        self.incSavbtn.setMinimumSize(QtCore.QSize(x,y))
        self.emailbtn=QtGui.QPushButton("Email")
        self.emailbtn.setMinimumSize(QtCore.QSize(x,y))
        self.upldbtn=QtGui.QPushButton("Upload")
        self.upldbtn.setMinimumSize(QtCore.QSize(x,y))
        self.setPrjbtn=QtGui.QPushButton("Set Project")
        self.setPrjbtn.setMinimumSize(QtCore.QSize(x,y))
        self.setThumb=QtGui.QPushButton("Set thumb")
        self.setThumb.setMinimumSize(QtCore.QSize(x,y))
        self.shwMatbtn=QtGui.QPushButton("Show Material")
        self.shwMatbtn.setMinimumSize(QtCore.QSize(x,y))
        self.fixtexbtn=QtGui.QPushButton("Fix Texture Paths")
        self.fixtexbtn.setMinimumSize(QtCore.QSize(x,y))
        btns = [self.incSavbtn,self.emailbtn,self.upldbtn,self.setPrjbtn,self.setPrjbtn,self.setThumb,self.shwMatbtn,self.fixtexbtn]
        [self.btnVLay.addWidget(each) for each in btns]
    def contextMenuEvent(self, event):
        menu = QtGui.QMenu(self)
        menu.addAction(self.emlSel)
        menu.addAction(self.emlScn)
        menu.addAction(self.emlBufr)
        #menu.exec_(self.emailbtn.mapToGlobal(QtCore.QPoint(0,0)))
        #menu.exec_(event.globalPos())
    def createActions(self):
        self.emlSel = QtGui.QAction("Email Selected", self)
        self.emlScn = QtGui.QAction("Email this Scene", self)
        self.emlBufr = QtGui.QAction("Email Current Frame Buffer", self)

    def floatingToolBar(self):
        self.buttons()
        self.setLayout(self.btnVLay)
        self.show()
        pass
if __name__ =='__main__':
    app = QtGui.QApplication(sys.argv)
    win = ToolBarUI()
    win.show()
    sys.exit(app.exec_())

我已经尝试了contextMenuEvent方法，但这给了我右键单击:/我错过了什么?

Answer 1

可以在Linux中使用，但不能在windows中使用。

下面是我在windows中使用左键支持的systemtrayicon的代码。这可能也适用于您。

QtCore.QObject.connect(self, QtCore.SIGNAL("activated(QSystemTrayIcon::ActivationReason)"), self.iconActivated)   
def iconActivated(self, reason):
    if reason == QtGui.QSystemTrayIcon.Trigger: // left click, right click is Context
        self.contextMenu().activateWindow() // menu will disappear on clicking any where other than menu
        self.contextMenu().popup(QtGui.QCursor.pos()) // display menu at cursor location

看起来你可以使用setMenu方法:

#!/usr/bin/env python
#-*- coding:utf-8 -*-
from PyQt4 import QtCore, QtGui
class myWindow(QtGui.QWidget):  
    def __init__(self, parent=None):
        super(myWindow, self).__init__(parent)
        self.actionHello = QtGui.QAction(self)
        self.actionHello.setText("Hello")
        self.menu = QtGui.QMenu(self)
        self.menu.addAction(self.actionHello)
        self.buttonShow = QtGui.QPushButton(self)
        self.buttonShow.setText("Button with menu")
        self.buttonShow.setMenu(self.menu)
        self.layout = QtGui.QVBoxLayout(self)
        self.layout.addWidget(self.buttonShow)

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    app.setApplicationName('myWindow')
    main = myWindow()
    main.show()
    sys.exit(app.exec_())
