我想知道如何使用PyQt4创建一个派生的 QTabWidget 与每个选项卡标题旁边的复选框?像这样:
解决方案
实际上,我选择了只是子类QTabWidget。 在创建一个新标签页时添加复选框,并保存到列表,以便将其索引返回。 setCheckState / isChecked方法旨在控制由其标签索引指定的每个复选框的状态。 最后,stateChanged int)信号被捕获并且通过指定相关复选框的索引的额外参数被汇出。
class CheckableTabWidget (QtGui.QTabWidget): checkBoxList = [] def addTab(self,widget,title): QtGui.QTabWidget.addTab(self,widget,标题) checkBox = QtGui.QCheckBox() self.checkBoxList.append(checkBox) self.tabBar()。setTabButton(self.tabBar()。count() - 1,QtGui .QTabBar.LeftSide,checkBox) self.connect(checkBox,QtCore.SIGNAL('stateChanged(int)'),lambda checkState:self .__ emitStateChanged(checkBox,checkState)) def isChecked(self,index): return self.tabBar()。tabButton(index,QtGui.QTabBar.LeftSide).checkState()!= QtCore.Qt.Unchecked def setCheckState self,index,checkState): self.tabBar()。tabButton(index,QtGui.QTabBar.LeftSide).setCheckState(checkState) def __emitStateChanged(self,checkBox,checkState): index = self.checkBoxList.index(checkBox) self.emit(QtCore.SIGNAL('stateChanged(int,int)'),index,checkState)这可能不是最好的方法,但至少它仍然很简单,涵盖我所有的需要。
I was wondering how to create (using PyQt4) a derived QTabWidget with a check box next to each tab title? Like this:
解决方案Actually I chose to only subclass QTabWidget. The checkBox is added at the creation of a new tab and saved to a list in order to get its index back. setCheckState/isChecked methods are intended to control the state of each checkBox specified by its tab index. Finally, the "stateChanged(int)" signal is captured and remitted with an extra parameter specifying the index of the checkBox concerned.
class CheckableTabWidget(QtGui.QTabWidget): checkBoxList = [] def addTab(self, widget, title): QtGui.QTabWidget.addTab(self, widget, title) checkBox = QtGui.QCheckBox() self.checkBoxList.append(checkBox) self.tabBar().setTabButton(self.tabBar().count()-1, QtGui.QTabBar.LeftSide, checkBox) self.connect(checkBox, QtCore.SIGNAL('stateChanged(int)'), lambda checkState: self.__emitStateChanged(checkBox, checkState)) def isChecked(self, index): return self.tabBar().tabButton(index, QtGui.QTabBar.LeftSide).checkState() != QtCore.Qt.Unchecked def setCheckState(self, index, checkState): self.tabBar().tabButton(index, QtGui.QTabBar.LeftSide).setCheckState(checkState) def __emitStateChanged(self, checkBox, checkState): index = self.checkBoxList.index(checkBox) self.emit(QtCore.SIGNAL('stateChanged(int, int)'), index, checkState)This is maybe not the perfect way to do things, but at least it remains pretty simple and covers all my needs.
