python - 如何调整 PyQt 窗口的大小

问题描述

我创建了一个 pyqt 窗口，其中包含一个 GridLayout。此 GridLayout 包含 4 个按钮。

当使用鼠标手动调整窗口大小时，按钮的大小不会改变以适应新的窗口大小。

我的目标是按钮的大小会发生变化以适应新的窗口大小，就像在响应式网页中一样。

我已经尝试过：

从 .ui 生成的 .py ：

class Ui_MainWindow(object):
def setupUi(self, MainWindow):
    MainWindow.setObjectName("MainWindow")
    MainWindow.resize(554, 415)
    palette = QtGui.QPalette()

    self.title.setTextFormat(QtCore.Qt.RichText)
    self.title.setObjectName("title")
    MainWindow.setCentralWidget(self.centralwidget)

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

任何想法 ？

解决方案

解决方案是使用 QGridLayout 并将垂直按钮大小策略设置为“最小”：

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
  <property name="geometry">

   </rect>
  </property>
  <property name="windowTitle">
   <string>MainWindow</string>
