Python 嵌套布局。。。绘制堆叠而非分层

好的。。。我错过了。我正在尝试创建一个对话框，该对话框有一个GridLayout，其中有许多复选框，下面是一个HBoxLayout中的接受、关闭按钮。但是在下面的代码中，我看到的只是HBoxLayout之上的GridLayout。为什么？如何将对话框尺寸标注为GridLayout的宽度

class CheckerDialog(QtGui.QDialog) :

    def __init__(self, parent, headers) :
        super(CheckerDialog, self).__init__(parent)

        checksLayout = QtGui.QGridLayout()
        self.cbList = []
        i  = 0
        for y in range(13):
            for x in range (9):
                if i == len(headers) : break
                cb = QtGui.QCheckBox(headers[i], self)
                cb.move(OFFSET_X + SPACER_X*x, OFFSET_Y + SPACER_Y*y)
                self.cbList.append(cb)
                i += 1

        buttonLayout = QtGui.QHBoxLayout()
        applyButton = QtGui.QPushButton("Apply")
        closeButton = QtGui.QPushButton("Close")
        buttonLayout.addWidget(applyButton)        
        buttonLayout.addWidget(closeButton)
        self.connect(applyButton, QtCore.SIGNAL('clicked()'), self._apply)
        self.connect(closeButton, QtCore.SIGNAL('clicked()'), self.close)

        checkerLayout = QtGui.QVBoxLayout()
        checkerLayout.addLayout(buttonLayout)
        checkerLayout.addLayout(checksLayout)

HBoxLayout位于GridLayout的顶部，而不是下方。 是的，它应该在你的代码中。序列在代码中有作用

    checkerLayout.addLayout(buttonLayout) # <- TOP
    checkerLayout.addLayout(checksLayout) # <- BOTTOM

GridLayout的大小并不控制 总体布局,， 是的，它应该再次出现在您的代码中。因为您没有在QGridLayout中放置复选框。您只需在根布局上设置几何图形，而不是QGridLayout。请使用QGridLayout.addWidget self、QWidget、int行、int列、Qt.Alignment Alignment=0添加小部件指定索引x、y

小例子：

import sys
from PyQt4 import QtGui

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

        checkBoxQGridLayout = QtGui.QGridLayout()
        for y in range(13):
            for x in range(9):
                currentQCheckBox = QtGui.QCheckBox('%d, %d' % (x, y))
                currentQCheckBox.setSizePolicy(QtGui.QSizePolicy(QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Minimum))
                checkBoxQGridLayout.addWidget(currentQCheckBox, x, y)

        buttonQHBoxLayout  = QtGui.QHBoxLayout()
        applyQPushButton = QtGui.QPushButton('Apply')
        closeQPushButton = QtGui.QPushButton('Close')
        buttonQHBoxLayout.addWidget(applyQPushButton)        
        buttonQHBoxLayout.addWidget(closeQPushButton)

        allQVBoxLayout = QtGui.QVBoxLayout()
        allQVBoxLayout.insertLayout(1, buttonQHBoxLayout)
        allQVBoxLayout.insertLayout(0, checkBoxQGridLayout)
        self.setLayout(allQVBoxLayout)

myQApplication = QtGui.QApplication(sys.argv)
myQQCheckerDialog = QCheckerDialog()
myQQCheckerDialog.show()
sys.exit(myQApplication.exec_())

另见：

好啊解决了的。。。很抱歉给你添麻烦。。。我需要一个自我。在支票台上。并且需要执行self.setLayoutself.checkerLayout。如果您自己解决，请发布您的答案。没有回答就关闭它。谢谢。实际上我需要修改一下。仍然有一个错误。将编辑主目录以澄清。错误？“self.setLayoutcheckerLayout并不能解决您的问题，或者您还有更多的问题？好吧，它显示了两种布局都是正确的。但是如上所述。。。。HBoxLayout位于GridLayout的顶部，而不是下方。GridLayout的大小并不控制整个布局的大小，我希望它这样做！
