Question

这是简单系统托盘 PyQt 应用程序的代码示例。

import sys
from PyQt4 import QtGui

def main():
   app = QtGui.QApplication(sys.argv)

   trayIcon = QtGui.QSystemTrayIcon(QtGui.QIcon( test.png ), app)
   menu = QtGui.QMenu()
   exitAction = menu.addAction("Exit")
   trayIcon.setContextMenu(menu)

   # I d like to show picture in tooltip, BUT IT S NOT WORK IN WINDOWS
   trayIcon.setTooltip( <img src="SomePicture.png" width="48" height="48"/> )

   trayIcon.show()
   sys.exit(app.exec_())

if __name__ ==  __main__ :
   main()

In this code I d like to show balloon tooltip with a some picture and some kind of text formating. For this purpose I use RichText tags formatting. As the result for Ubuntu Linux system (Gnome desktop) everything is Ok. But when I try use RichText formatting for tooltip in Windows XP system, nothing works. Tooltip text equals source string: . Python version on Windows 2.7, on Linux 2.6 but I think that problem is not in different versions.

在 Windows OS RichText 中, 如果 Windows OS RichText 没有解析, 我如何制作相同的图形界面?

如果有人也有兴趣创建气球部件。这是我的代码:

class SystemTrayIcon(QtGui.QSystemTrayIcon):
    def __init__(self, parent = None): 
        QtGui.QSystemTrayIcon.__init__(self, icon, parent)
        traySignal = "activated(QSystemTrayIcon::ActivationReason)"
        self.connect(self, QtCore.SIGNAL(traySignal), self._activateRoutine)
        self.balloon = balloonWidget(name)

    def _activateRoutine(self, reason):
        if reason == QtGui.QSystemTrayIcon.Trigger:
            self.balloon.show(self.geometry())

class balloonWidget(QtGui.QWidget):
    def __init__(self,name):
        QtGui.QWidget.__init__(self, parent = None, flags = QtCore.Qt.Popup)

        self.name = name

        self.offsetX = 10
        self.offsetY = 10

        self.outInfo = QtGui.QLabel(self)

        self.setStyleSheet("QWidget {border:5px solid rgb(170, 170, 255);}")

    def show(self,coord):
        richText = tr( Any text with Rich Format )
        self.outInfo.setText(richText)
        self.outInfo.show()
        self.adjustSize()

        origin = QtGui.QDesktopWidget().availableGeometry().bottomRight()

        if coord.y() < origin.y()/2:
            moveY = coord.bottomLeft().y() + self.offsetY
        else:
            moveY = coord.topLeft().y() - (self.height() + self.offsetY)

        if coord.x() + self.width() + self.offsetX >= origin.x():
            moveX = origin.x() - (self.width() + self.offsetX)
        else:
            moveX = coord.x()

        self.move(moveX,moveY)
        self.setVisible(True)

    def closeEvent(self, event):
        event.ignore()
        self.hide()

    def mousePressEvent(self, event):
        self.close()

在 Windows Qt 上使用只支持文字的 os tooltip 系统。

如果您想要更先进的东西, 您可以 < a href="http://qt- project. org/ doc/ qsyrayicon.html#showMessage" rel="no follow"\\ code\ systemTrayIcon.showMessage () 使用所谓的 < a href=" http://qt- project.org/doc/desktop-systray.html" rel="nofol" > here 。您可能必须安装事件过滤器或推翻 < event 方法来获取帮助事件。
