我有以下代码:
##### Slots for checkboxes (enable/disabling)
QtCore.QObject.connect(self.checkBox_3, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), self.checkBox_3.setOn)
QtCore.QObject.connect(self.checkBox_3, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), self.dateEdit.setEnabled)
QtCore.QObject.connect(self.checkBox_3, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), self.dateEdit_2.setEnabled)
QtCore.QObject.connect(self.checkBox, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), self.lineEdit.setEnabled)
QtCore.QObject.connect(self.checkBox_2, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), self.lineEdit_2.setEnabled)
QtCore.QObject.connect(self.checkBox_4, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), self.lineEdit_3.setEnabled)
#####
##### Slots for checkboxes/lineEdits (filling dict for database fields and values)
QtCore.QObject.connect(self.checkBox, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), lambda: self.interfaceCodesConstructor.setFilterDict(self,"name",self.lineEdit.text()))
QtCore.QObject.connect(self.checkBox_2, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), lambda: self.interfaceCodesConstructor.setFilterDict(self,"bought_price",persianToInteger(unicode(self.lineEdit_2.text()))))
QtCore.QObject.connect(self.checkBox_3, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), lambda: self.interfaceCodesConstructor.setFilterDict(self,"bought_date",self.dateEdit.text())) ##date
QtCore.QObject.connect(self.checkBox_4, QtCore.SIGNAL(_fromUtf8("stateChanged(int)")), lambda: self.interfaceCodesConstructor.setFilterDict(self,"stock",persianToInteger(unicode(self.lineEdit_3.text()))))
QtCore.QObject.connect(self.lineEdit, QtCore.SIGNAL(_fromUtf8("editingFinished()")), lambda: self.interfaceCodesConstructor.responseToRequestForData(self))
QtCore.QObject.connect(self.lineEdit_2, QtCore.SIGNAL(_fromUtf8("editingFinished()")), lambda: self.interfaceCodesConstructor.responseToRequestForData(self))
QtCore.QObject.connect(self.dateEdit, QtCore.SIGNAL(_fromUtf8("editingFinished()")), lambda: self.interfaceCodesConstructor.responseToRequestForData(self))
QtCore.QObject.connect(self.lineEdit_3, QtCore.SIGNAL(_fromUtf8("editingFinished()")), lambda: self.interfaceCodesConstructor.responseToRequestForData(self))
#### pressing seach key and start search action
QtCore.QObject.connect(self.lineEdit, QtCore.SIGNAL(_fromUtf8("returnPressed()")), lambda: self.interfaceCodesConstructor.responseToRequestForData(self))
QtCore.QObject.connect(self.pushButtonSearch, QtCore.SIGNAL(_fromUtf8("clicked()")), lambda: self.interfaceCodesConstructor.responseToRequestForData(self))
#######
## enable/disabling "price date" checkbox
QtCore.QObject.connect(self.checkBox_3, QtCore.SIGNAL(_fromUtf8("toggled(bool)")), self.dateEdit.setEnabled)
QtCore.QObject.connect(self.checkBox_3, QtCore.SIGNAL(_fromUtf8("toggled(bool)")), self.dateEdit_2.setEnabled)
然后我SLOT
在另一个文件中有以下内容:
def setFilterDict(self,obj,field,lineEditContent):
self.objectSearchMaterials = obj
if field not in self.filterNameDict.keys():# and self.filterNameDict.values() is not None:
self.filterNameDict.update({field:lineEditContent})
else:
del self.filterNameDict[field]
我的问题是,当我单击时checkboxes
,我用文本填充字典:self.filterNameDict
,但是当我单击多次时,它无法处理给定的字典。我如何创建一个动态字典来处理每个checkboxes
?这意味着当我单击checkbox
添加字段名称和lineEdit text()
字典时我需要,当我删除它时,自动从字典中删除?
