Question

我可以使用下面的代码正确地获得布局，如何在水平和垂直方向调整此QGridLayout的大小？

self._s_q0= QLabel(u'what is your favorite color?')
self._e_q0 = QLineEdit(self)
self._e_q0.setText("yellow is the best color I can think of")

self._s_q1= QLabel(u'what is your favorite animal?')
self._e_q1 = QLineEdit(self)
self._e_q1.setText("cat or dog")

self._s_q2= QLabel(u'do you like swimming?')
self._e_q2 = QLineEdit(self)
self._e_q2.setText("not at all")

self._s_q3= QLabel(u'what date is it today?')
self._e_q3 = QLineEdit(self)
self._e_q3.setText("i dont know, you can ask Tom, he has a cellphone with him right now")



self._groupData = QGroupBox("100 questions list", self)
self._groupData_layout = QGridLayout()
self._groupData.setLayout(self._groupData_layout)



self._groupData_layout.addWidget(self._s_q0, 0, 0)
self._groupData_layout.addWidget(self._e_q0, 0, 1)

self._groupData_layout.addWidget(self._s_q1, 1, 0)
self._groupData_layout.addWidget(self._e_q1, 1, 1)        

self._groupData_layout.addWidget(self._s_q2, 2, 0)
self._groupData_layout.addWidget(self._e_q2, 2, 1)

self._groupData_layout.addWidget(self._s_q3, 3, 0)
self._groupData_layout.addWidget(self._e_q3, 3, 1)

添加更多说明。我可以正确地获得布局，现在代码生成的布局如下所示。

此布局的宽度太宽，如何将其调整为较小但不更改字体大小，如何向此QGridLayout添加scorll bar？

相同的高度，有100个问题，QGridLayout将太长，无法显示它们。如何调整QGridLayout的高度，滚动条？

下图是我想要的最终结果

仅显示部分布局以节省UI空间。拖动滚动条以显示此布局的其他部分。我不知道如何在代码中做到这一点，只需用油漆编辑图片。

首先要做的是创建一个显示小部件结构的图表，在这种情况下我们可以使用下图：

.
└── groupbox
    └── scrollarea
        └── contents
            ├── form
            └── spaceritem

然后您必须处理某些策略来处理大小，下一部分显示结果代码

代码：

class GroupBox(QGroupBox):
    def __init__(self, *args, **kwargs):
        QGroupBox.__init__(self, *args, **kwargs)
        vlayout = QVBoxLayout(self)
        scrollArea = QScrollArea(self)
        scrollArea.setWidgetResizable(True)
        self.scrollAreaWidgetContents = QWidget()
        scrollArea.setWidget(self.scrollAreaWidgetContents)
        vlayout.addWidget(scrollArea)
        hlayout = QHBoxLayout(self.scrollAreaWidgetContents)
        flayout = QFormLayout()
        hlayout.addLayout(flayout)
        hlayout.addItem(QSpacerItem(170, 20, QSizePolicy.Expanding, QSizePolicy.Minimum))
        for i in range(100):
            le = QLineEdit(self.scrollAreaWidgetContents)
            le.setText("i dont know, you can ask Tom, he has a cellphone with him right now")
            le.setSizePolicy(QSizePolicy.Minimum, QSizePolicy.Fixed)
            flayout.addRow("what date is it {}".format(i), le)


if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    app.setStyle("fusion")
    w = QWidget()
    w.setLayout(QVBoxLayout())
    g = GroupBox("100 questions list")
    w.layout().addWidget(g)
    w.show()
    sys.exit(app.exec_())
