Pyside 更改布局 [英] Pyside Changing Layouts

问题描述

我有一个界面，屏幕顶部有 4 个按钮，下面有 QFrame.我想根据按下的按钮更改 QFrame 中的布局.例如，如果按下 Button_1 显示一个 TextEdit Widget，如果按下 Button_2 显示一个 ListViewWidget.

I have a Interface that has 4 buttons across the top of the screen, and below that I have QFrame. I want to change the layout in the QFrame based on what button is pressed. For instance, if Button_1 is pressed show a TextEdit Widget, if Button_2 is pressed show a ListViewWidget.

有没有人知道如何做到这一点?非常感谢！

Does anyone have any idea on how this can be done? Thank You Very Much!

推荐答案

使用 QStackedLayout 用于存储您的小部件.然后你可以更改为 setCurrentIndex.或者，您可以使用 QStackedWidget 在QFrame 的位置.

一个简单的例子:

import sys
from PySide import QtGui

class Window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        self.textEdit = QtGui.QTextEdit('Text Edit')
        self.listWidget = QtGui.QListWidget()
        self.listWidget.addItem('List Widget')
        self.label = QtGui.QLabel('Label')

        self.stackedLayout = QtGui.QStackedLayout()
        self.stackedLayout.addWidget(self.textEdit)
        self.stackedLayout.addWidget(self.listWidget)
        self.stackedLayout.addWidget(self.label)

        self.frame = QtGui.QFrame()
        self.frame.setLayout(self.stackedLayout)

        self.button1 = QtGui.QPushButton('Text Edit')
        self.button1.clicked.connect(lambda: self.stackedLayout.setCurrentIndex(0))
        self.button2 = QtGui.QPushButton('List Widget')
        self.button2.clicked.connect(lambda: self.stackedLayout.setCurrentIndex(1))
        self.button3 = QtGui.QPushButton('Label')
        self.button3.clicked.connect(lambda: self.stackedLayout.setCurrentIndex(2))

        buttonLayout = QtGui.QHBoxLayout()
        buttonLayout.addWidget(self.button1)
        buttonLayout.addWidget(self.button2)
        buttonLayout.addWidget(self.button3)

        layout = QtGui.QVBoxLayout(self)
        layout.addLayout(buttonLayout)
        layout.addWidget(self.frame)


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    w = Window()
    w.show()

    sys.exit(app.exec_())
