如何将水平滚动条与多个组框关联。

Question

我想在对话框中总共有8个groupbox。我不知道如何关联水平滚动条，以便我可以向下滚动并访问所有组框。在下面的代码中，我仅添加了2作为示例。任何帮助表示赞赏。

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 300)
        self.buttonBox = QtGui.QDialogButtonBox(Dialog)
        self.buttonBox.setGeometry(QtCore.QRect(300, 20, 81, 71))
        self.buttonBox.setOrientation(QtCore.Qt.Vertical)
        self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok)
        self.buttonBox.setObjectName("buttonBox")
        self.scrollArea = QtGui.QScrollArea(Dialog)
        self.scrollArea.setGeometry(QtCore.QRect(30, 20, 251, 251))
        self.scrollArea.setWidgetResizable(True)
        self.scrollArea.setObjectName("scrollArea")
        self.scrollAreaWidgetContents = QtGui.QWidget(self.scrollArea)
        self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0, 249, 249))
        self.scrollAreaWidgetContents.setObjectName("scrollAreaWidgetContents")
        self.groupBox = QtGui.QGroupBox(self.scrollAreaWidgetContents)
        self.groupBox.setGeometry(QtCore.QRect(10, 10, 211, 81))
        self.groupBox.setObjectName("groupBox")
        self.textEdit = QtGui.QTextEdit(self.groupBox)
        self.textEdit.setGeometry(QtCore.QRect(10, 20, 171, 51))
        self.textEdit.setObjectName("textEdit")
        self.groupBox_2 = QtGui.QGroupBox(self.scrollAreaWidgetContents)
        self.groupBox_2.setGeometry(QtCore.QRect(10, 110, 211, 111))
        self.groupBox_2.setObjectName("groupBox_2")
        self.textEdit_2 = QtGui.QTextEdit(self.groupBox_2)
        self.textEdit_2.setGeometry(QtCore.QRect(10, 20, 171, 84))
        self.textEdit_2.setObjectName("textEdit_2")
        self.verticalScrollBar = QtGui.QScrollBar(self.scrollAreaWidgetContents)
        self.verticalScrollBar.setGeometry(QtCore.QRect(230, 0, 16, 241))
        self.verticalScrollBar.setOrientation(QtCore.Qt.Vertical)
        self.verticalScrollBar.setObjectName("verticalScrollBar")
        self.scrollArea.setWidget(self.scrollAreaWidgetContents)

        self.retranslateUi(Dialog)
        QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL("accepted()"), Dialog.accept)
        QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL("rejected()"), Dialog.reject)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        Dialog.setWindowTitle(QtGui.QApplication.translate("Dialog", "Dialog", None, QtGui.QApplication.UnicodeUTF8))
        self.groupBox.setTitle(QtGui.QApplication.translate("Dialog", "GroupBox", None, QtGui.QApplication.UnicodeUTF8))
        self.groupBox_2.setTitle(QtGui.QApplication.translate("Dialog", "GroupBox", None, QtGui.QApplication.UnicodeUTF8))


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_())

正如我在评论中所说，QScrollArea不需要手动QScrollBar。它将在需要时创建。如果没有看到“不工作”代码，我无法确定你的问题是什么，但我的猜测是固定大小的项目及其位置。你可能把东西放在小部件边缘之外或者相互重叠，这样内部小部件就不会适当增长。

无论如何，这是一个复制对话框的最小例子（请注意滚动条）：

import sys
from PyQt4 import QtGui, QtCore

class MyDialog(QtGui.QDialog):
    def __init__(self, parent=None):
        super(MyDialog, self).__init__(parent)

        scrolllayout = QtGui.QVBoxLayout()

        scrollwidget = QtGui.QWidget()
        scrollwidget.setLayout(scrolllayout)

        scroll = QtGui.QScrollArea()
        scroll.setWidgetResizable(True)  # Set to make the inner widget resize with scroll area
        scroll.setWidget(scrollwidget)

        self.groupboxes = []  # Keep a reference to groupboxes for later use
        for i in range(8):    # 8 groupboxes with textedit in them
            groupbox = QtGui.QGroupBox('%d' % i)
            grouplayout = QtGui.QHBoxLayout()
            grouptext = QtGui.QTextEdit()
            grouplayout.addWidget(grouptext)
            groupbox.setLayout(grouplayout)
            scrolllayout.addWidget(groupbox)
            self.groupboxes.append(groupbox)

        self.buttonbox = QtGui.QDialogButtonBox()
        self.buttonbox.setOrientation(QtCore.Qt.Vertical)
        self.buttonbox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok)

        layout = QtGui.QHBoxLayout()
        layout.addWidget(scroll)
        layout.addWidget(self.buttonbox)
        self.setLayout(layout)

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    dialog = MyDialog()
    dialog.show()
    sys.exit(app.exec_())
