Question

Python 3.4，PyQt5，QtDesigner

我使用QtDesigner创建了一个GUI，但是由它生成的python应用程序GUI与QtDesigner显示的预览不匹配。似乎问题与我的网格布局的尺寸/间距有关。我没有手动编辑GUI中的任何内容，所有代码都是由QtDesigner创建的。

QtDesigner预览和应用程序GUI：

QtDesigner .ui文件：

使用pyuic将.ui文件转换为testGUI.py。

这是应用程序代码：

import sys
from PyQt5 import QtCore, QtGui, QtWidgets
from testGUI import Ui_MainWindow

class App(Ui_MainWindow):
    def __init__(self, dialog):
        Ui_MainWindow.__init__(self)
        self.setupUi(dialog)


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    dialog = QtWidgets.QMainWindow()

    testGUI = App(dialog)

    dialog.show()
    sys.exit(app.exec_())

Answer 1

当我最初创建GUI时，我首先添加了一个网格布局窗口小部件QGridLayout，然后用项目填充它，然后将其拖动并将其放在组框容器QGroupBox中。

我完全没有使用QGridLayout解决了这个问题，只是简单地将项目添加到QGroupBox，然后将网格布局应用到容器中。应用程序GUI现在与QtDesigner预览相匹配。

QtDesigner预览与实际GUI不同
