如何将水平滚动条关联到多个分组框.? [英] How to associate a horizontal scrollbar to multiple groupbox.?

问题描述

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

I wanted to have a total of 8 groupbox in the Dialog box. I don't know how to associate the horizontal scrollbar so that I can scroll it down and access all the group box. In the code below I have added only 2 as an example. Any help is appreciated.

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_())

推荐答案

正如我在评论中所说，QScrollArea 不需要手动 QScrollBar.它会在需要时创建.如果没有看到不工作"代码，我无法确定您的问题是什么，但我的猜测是固定大小的项目及其位置.您可能将东西放在小部件边缘之外或彼此重叠，从而使内部小部件无法适当增长.

As I said in the comments, QScrollArea doesn't need manual QScrollBar. It will create when needed. I can't be sure what your problem is without seeing the 'not working' code, but my guess is the fixed sized items and their placement. You are probably putting things outside of the widgets margin or overlapping each other so that the inner widget does not grow appropriately.

无论如何，这是一个复制对话框的最小示例(注意滚动条):

Anyway, here is a minimal example that replicates your dialog (notice the scrollbar):

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_())
