Qt显示带有文本输入的消息框

Question

在 Qt4(实际上是 PyQt4)中是否有任何简单明了的方法来显示支持文本输入的消息框，而不是仅仅从预定义列表中选择一个按钮？我可以(并且已经部分地)通过编写一个仅用于显示此类对话框的自定义类来完成此操作，但是没有更简洁的方法吗？

编辑:感谢 Luca Carlon，我让它工作了。但是为了以防万一其他人需要这个，我将在下面发布工作的 PyQt4 代码

from PyQt4.QtGui import QInputDialog
#This code works only inside a method of a widget or window as self must refer to a
#valid widget or window to get the correct modality, although we can give None instead
(text,truth)=QInputDialog.getText(self,"Get text","User name",QLineEdit.Normal,"NoName")
if truth:
    #The user has accepted the edit, he/she has clicked OK
    print text
else:
    #The user has not accepted the edit, he/she has clicked Cancel
    print "No change"

为此使用 QInputDialog。静态方法 getText 可能就足够了。
