我想要生成一個GridLayout(CheckBox的)和HLayout堆疊佈局的對話框。那麼,我做到了。但我的網格變大了(我的HLayout很好),但現在我想要一個ScrollArea,以免佔用太多的房地產。我嘗試了下面的代碼....它會生成一個滾動視圖,但滾動視圖的大小是HLayout中按鈕的大小(第一個ofc)。我希望滾動視圖是對話框的寬度,名義上它應該是HLayout的最小寬度。此外,添加scroll_view和scroll_viewWidget會引發QLayout異常,QLayout :: addChildLayout:layout「」已經有父級。有任何想法嗎?Python PyQt QScrollArea和QGridLayout(或任何?)
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)
沒錯!那是做的......你說我不明白爲什麼,我很抱歉。 – 2014-09-03 22:29:19
@TimCarnahan你在'checkerLayout'上兩次調用'addLayout'。 mdurant嵌套可能是你想要的佈局。 – Trilarion 2014-09-04 08:55:56
順便說一句,我建議使用QtDesigner來製作複雜的GUI,即使在運行時需要動態填充某些元素,也會帶來很多痛苦。 – mdurant 2014-09-04 12:32:37
