PySide 使 QDialog 出现在主窗口中 [英] PySide make QDialog appear in main window

问题描述

我创建了一个应用程序，它有一个主窗口并且可以打开一个对话框(问题、错误等).我没有使用 QMessageBox.warning() 或 QMessageBox.question() 等等，因为我想稍微自定义一下对话框.

I've created an app which has an main window and the possibility to open an dialog (question, error and so on). I'm not using QMessageBox.warning() or QMessageBox.question() and so on because I wanted to customize the dialogs a bit.

但是每次我打开一个新对话框时，都会在 Windows 任务栏中(我使用的是 Windows 10)打开一个新的选项卡"，这有点烦人.

But every time I open a new Dialog, in the Windows task bar (I'm working on Windows 10) a new 'tab' is opened, which is a little bit annoying.

我的代码(缩短):

from PySide import QtCore, QtGui
import sys

class MessageBox:
    def __init__(self, title, message):
        msg = QtGui.QMessageBox()
        flags = QtCore.Qt.Dialog
        flags |= QtCore.Qt.CustomizeWindowHint
        flags |= QtCore.Qt.WindowTitleHint
        msg.setWindowFlags(flags)
        msg.setWindowTitle(title)
        msg.setText(message)
        msg.exec_()

class MainWindow(QtGui.QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.show()

        MessageBox("Title", "My message here")

if __name__ == "__main__":
    app = QtGui.QApplication([])
    window = MainWindow()
    sys.exit(app.exec_())

注意:通常，对话框是从菜单或按钮调用的.

Note: Normally, the dialog is called from an menu or button.

问题:如何在不创建新的任务栏选项卡"的情况下使对话框出现在主窗口中?

Question: How can I make the dialog appear in the main window without creating a new 'task bar tab'?

推荐答案

解决方案非常简单:将 QMainWindow 的引用传递给 QDialog 的构造函数即可完成工作，例如:

The solution was quite simple: Passing an reference of QMainWindow to the constructor of QDialog will do the job, e.g:

class MessageBox(QtGui.QDialog):
    def __init__(self, parent, title, message, icon="info"):
        super(MessageBox, self).__init__(parent)
        ...

然后从继承自 QMainWindow 的类调用对话框:

and then calling the dialog from an class that inherits from QMainWindow:

class MainWindow(QtGui.QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        #connect button with function, e.g.:
        mybutton.clicked.connect(self.open_dialog)

   def open_dialog(self):
       MessageBox(self)

也许这对任何人都有帮助！
