Question

我已经使用PyQt Designer创建了一个简单的GUI，并使其将.ui文件转换为python代码。

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _fromUtf8(s):
        return s

try:
    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig)

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

现在，我想添加一个滚动条，该滚动条在调整主窗口大小时显示。换句话说：如果用户调整主窗口的大小以使内容的大小大于窗口本身的大小，则应显示滚动条。我的GUI的更复杂的代码可以在这里找到：https://snip.dssr.ch/?efe8c61b137f0751#IGcw4iGEOTHYlXTseCc+Z7tPDDPVtgAeAPx5A4P8pnc=

有什么想法要实现吗？

您需要使用QScrollArea。代替

self.layoutWidget = QtGui.QWidget(Dialog)

做类似的事情

self.scrollLayout = QtGui.QVBoxLayout(Dialog)
self.scrollBox = QtGui.QScrollArea()
self.scrollLayout.addWidget(self.scrollBox)
self.mainWidget = QtGui.QWidget()
self.scrollBox.setWidget(self.mainWidget)
self.mainLayout = QtGui.QVBoxLayout(self.mainWidget)

然后，像这样的每一行

self.foo = QtGui.QWidget(Dialog)

您需要将Dialog换成self.mainWidget，或将其显式添加到布局中。

self.foo = QtGui.QWidget()
self.mainLayout.addWidget(self.foo)

这也可以使用Designer完成。不过我不确定。

在PyQt中追溯添加滚动条
