我有一个循环.我创建了一个 QCheckBox
并将它放在一个 QTableWidget
单元格中,一切正常.在循环的每一步中,我都为 myslot SLOT 调用了一个 connect
函数,但只应用了最后一个 QCheckBox
实例.我用谷歌搜索了很多,发现很多人都有我的问题.我已经应用了他们的解决方案,但我的问题仍然存在.
I have got a loop. I created a QCheckBox
and put it in a QTableWidget
cell, and everything is Ok. In each step of loop I have called a connect
function, for myslot SLOT, but only the last QCheckBox
instance is applied. I googled a lot and have found many people have my problem. I have applied their solutions, but my problem remains.
for row in xrange(len(uniqueFields)):
instance = QtGui.QCheckBox(uniqueFields[row], findInstance.tableWidget)
print QtCore.QObject.connect(instance,
QtCore.SIGNAL(_fromUtf8("stateChanged (int)")),
lambda: findInstance.projectsInstance.myslot(
"TWCH", findInstance, instance.text(),
instance.checkState(), instance))
findInstance.tableWidget.setRowCount(findInstance.tableWidget.rowCount() + 1)
findInstance.tableWidget.setCellWidget(row, 0, instance)
注意:我的connect
函数返回True
.
如何在枚举所有实例
的循环中创建connect
函数?
How to create connect
function in a loop that enumerates all of the instances
?
我有同样的问题,你应该使用 functools.partial
如:
I have same problem , you should use functools.partial
such as:
for key, val in a_DICT_THAT_YOU_STORED_YOUR_OBJECTS_AND_STRINGS:
obj = partial( findInstance.projectsInstance.myslot,arg1="TWCH",arg2=self,arg3=key,arg4=val.checkState() )
QtCore.QObject.connect(val, QtCore.SIGNAL(_fromUtf8("stateChanged (int)")), obj)
当然,argX 应该设置为你的函数名参数的真实名称.
Of course, argX should set to your real name of your argument of your function name.
这篇关于循环中的 QtCore.QObject.connect 只影响最后一个实例的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
