Qt 设计器 UI (python) 到 JSON [英] Qt Designer UI (python) to JSON

问题描述

我最近开始使用 qt 来构建 Python GUI.我有两个问题，我无法完全找到解决方案.下面的代码是我需要构建的示例.

I recently started using qt to build a python GUI. I have two problems I can't quite find the solutions to. the code below is a sample of what I need to build.

1:检查垂直布局中的单选按钮列表中的哪个单选按钮已被单击.在 GUI 中，它仅从布局中的所有其他可用单选按钮中选择一个.我怎么知道哪个被点击了?

1: Check which radio button from a list of radio buttons in a vertical layout has been clicked. In the GUI it only selects one radio button out of all others available in the layout. How do I perceive which has been clicked?

2:我想将单击的值添加到 JSON 对象中，但我相信这是一个简单的 if 语句，即 if this then that.除非它更复杂，在这种情况下，请把我推向正确的方向.

2:I would like to add the clicked value to a JSON object but I believe that is a simple if statement of if this then that. Unless it's more complicated in which case please push me in the right direction.

        self.sure = QtWidgets.QRadioButton(self.verticalLayoutWidget)
        self.sure.setObjectName("sure")
        self.verticalLayout.addWidget(self.sure)

        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.that.setText(_translate("Dialog", "that"))
        self.thi.setText(_translate("Dialog", "this"))
        self.sure.setText(_translate("Dialog", "sure"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()
    sys.exit(app.exec_())

推荐答案

使用 Qt Designer 有一个很好的方法可以解决这个问题，它允许您将按钮分组到QButtonGroup，然后连接到它的buttonClicked 信号 获取被点击的按钮.

There is a nice way to solve this using Qt Designer, which allows you to group your buttons into a QButtonGroup, and then connect to its buttonClicked signal to get the button that was clicked.

您需要做的就是，在 Qt Designer 中，选择所有按钮(使用 Ctrl+单击)，然后右键单击其中一个按钮并选择分配给按钮组 -> 新建按钮组.这将创建一个新的按钮组对象并自动将所有按钮添加到其中.

All you need to do is, in Qt Designer, select all the buttons (using Ctrl+click), then right-click one of the buttons and select Assign to button group -> New button group. This will create a new button-group object and automatically add all the buttons to it.

重新生成您的 gui 模块后，您可以执行以下操作:

After re-generating your gui module, you can then do somehting like this:

ui.radioButtonGroup.buttonClicked.connect(radioButtonClicked)

def radioButtonClicked(button):
    print(button.text())
