习惯了Delphi、c#调用系统MessageBox本地化显示,待用PySide调用时,Qt原生提示对话框,默认以英文显示。

如何本地化呢?

参考些资料,加以摸索,实现所需效果。并可根据此思路,设计自己所需要的MessageBox封装。

    QTextCodec.setCodecForTr(QTextCodec.codecForName("UTF-8"))
box = QMessageBox(QMessageBox.Question, self.tr("提示"), self.tr("您确定要退出吗?"), QMessageBox.NoButton, self)
yr_btn = box.addButton(self.tr("是"), QMessageBox.YesRole)
box.addButton(self.tr("否"), QMessageBox.NoRole)
box.exec_()
if box.clickedButton() == yr_btn:
print 'Bye bye...'
return
else:
print '继续...'

效果如下图示:

直接以.exec_()判断,[是]按钮返回0,尚不知如何与QMesageBox.YesRole对应。但若使用QMessageBox.AcceptRole与QMessageBox.RejectRole则可以。

下面代码,摘自PySide自带例子:

    MESSAGE = "<p>Message boxes have a caption, a text, and up to three " \
"buttons, each with standard or custom texts.</p>" \
"<p>Click a button to close the message box. Pressing the Esc " \
"button will activate the detected escape button (if any).</p>" msgBox = QMessageBox(QMessageBox.Question,
"QMessageBox.warning()", MESSAGE,
QMessageBox.NoButton, self)
msgBox.addButton("Save &Again", QMessageBox.AcceptRole)
msgBox.addButton("&Continue", QMessageBox.RejectRole)
if msgBox.exec_() == QMessageBox.AcceptRole:
print "Save Again"
else:
print "Continue"

显示如图:

另一种分步方案:

    box = QtGui.QMessageBox()
box.setIcon(QtGui.QMessageBox.Question)
box.setWindowTitle('Kaydet!')
box.setText('Kaydetmek İstediğinize Emin Misiniz?')
box.setStandardButtons(QtGui.QMessageBox.Yes | QtGui.QMessageBox.No)
buttonY = box.button(QtGui.QMessageBox.Yes)
buttonY.setText('Evet')
buttonN = box.button(QtGui.QMessageBox.No)
buttonN.setText('Iptal')
box.exec_() if box.clickedButton() == buttonY:
print 'YES pressed'
elif box.clickedButton() == buttonN:
print 'NO pressed'

谁可知之?大抵其官方文档可见些解释吧。一些是点击触发事件,一些仅是样式类似。
