Question

我正在尝试使用GridLayout（CheckBox＆＃39; s）和HLayout的堆叠布局生成一个Dialog。好吧，我做到了。但我的网格很大（我的HLayout很好），但现在我想要一个ScrollArea，以免占用太多房地产。我尝试了以下代码....它生成了一个滚动视图，但滚动视图的大小是HLayout中按钮（第一个ofc）的大小。我希望滚动视图是Dialog的宽度，名义上是HLayout的最小宽度。另外，添加scroll_view和scroll_viewWidget会导致引发QLayout异常，QLayout :: addChildLayout：layout＆＃34;＆＃34;已经有了父母。有什么想法吗？

class checkboxDialog(QtGui.QDialog) : 

def __init__(self, headers, name) :
    super(checkboxDialog, self).__init__()

    self.checkerLayout = QtGui.QVBoxLayout()
    self.checkerLayout.setMargin(1)
    self.checkerLayout.setSpacing(2)

    self.scroll_view = QtGui.QScrollArea(self)
    self.scroll_view.setWidgetResizable(True)

    self.scroll_viewWidget = QtGui.QWidget()
    self.scroll_viewWidget.setGeometry(QtCore.QRect(0, 0, 600, 400))
    self.scroll_view.setWidget(self.scroll_viewWidget)        

    self.checkerHlayout = QtGui.QHBoxLayout(self.scroll_viewWidget)

    checksLayout = QtGui.QGridLayout()
    checksLayout.setColumnStretch(90,7)
    checksLayout.setMargin(1)
    checksLayout.setSpacing(2)      
    self.cbList = []
    index  = 0
    for row_index in range(90):
        for column_index in range(7):
            if index > len(headers)-1 : break
            checkbox = QtGui.QCheckBox(headers[index][0:8], self)
            checkbox.setToolTip("Chanel = {}".format(headers[index]))
            self.cbList.append(checkbox)
            # Hide the Phase channels for now ... not sure I shoudl even build the CheckBoxes
            # But if I dont then the len(cbList) < len(data[0])
            if headers[index][-1] == 'p' :
                checkbox.hide()
            checksLayout.addWidget(checkbox, row_index, column_index)
            index += 1

    self.checkerHlayout.addLayout(checksLayout)

    self.buttonLayout = QtGui.QHBoxLayout()
    self.buttonLayout.setMargin(1)
    self.buttonLayout.setSpacing(2)

    applyButton = QtGui.QPushButton("Apply")
    nextButton = QtGui.QPushButton("Next")
    nextAllButton = QtGui.QPushButton("NextAll")
    prevButton = QtGui.QPushButton("Prev")
    prevAllButton = QtGui.QPushButton("PrevAll")
    clearButton = QtGui.QPushButton("Clear")

    self.buttonLayout.addWidget(applyButton)        
    self.buttonLayout.addWidget(nextButton)
    self.buttonLayout.addWidget(nextAllButton)
    self.buttonLayout.addWidget(prevButton)
    self.buttonLayout.addWidget(prevAllButton)
    self.buttonLayout.addWidget(clearButton)

    self.checkerLayout.addLayout(self.checkerHlayout)
    self.checkerLayout.addLayout(self.buttonLayout)
    self.setLayout(self.checkerLayout)

    self.setObjectName(name)
    self.setWindowTitle(name)

    self.connect(applyButton, QtCore.SIGNAL('clicked()'), self.checked)
    self.connect(nextButton, QtCore.SIGNAL('clicked()'), self.next_chn)
    self.connect(nextAllButton, QtCore.SIGNAL('clicked()'), self.next_chnAll)
    self.connect(prevButton, QtCore.SIGNAL('clicked()'), self.prev_chn)
    self.connect(prevAllButton, QtCore.SIGNAL('clicked()'), self.prev_chnAll)
    self.connect(clearButton, QtCore.SIGNAL('clicked()'), self.clear_chn)

我认为这就是你想要的：

    self.w2 = QtGui.QWidget(self)
    self.w2.setLayout(self.buttonLayout)
    self.checkerLayout.addWidget(self.w2)
    self.checkerLayout.addWidget(self.scroll_view)
    self.setLayout(self.checkerLayout)

（用addLayout语句替换块）

Python PyQt QScrollArea和QGridLayout（或任何？）
