如何将水平滚动条关联到多个groupbox。

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的组合框。在下面的代码中，我只添加了2个例子。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_())

正如我在评论中说，QScrollArea不需要人工QScrollBar。它将在需要时创建。如果没有看到“不能正常工作”的代码，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和他们的位置。你可能会把东西放在窗口小部件边缘之外或者互相重叠，这样内部窗口小部件的增长就不适当。

不管怎么说，这是一种可复制的对话框（注意滚动条）小例子：

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_())
