How to find an object by name in pyqt?

问题:

I have a list of dictionaries:

globalParams = [{'attr':'enabled','ctrl':'checkBoxEnabled','type':'checkBox'},
                {'attr':'colorMode','ctrl':'comboBoxColorMode','type':'comboBox'}]

'ctrl' - name of the control in the Qt window.

typically, the code is as follows:

self.checkBoxEnabled.checkState()

but checkBoxEnabled is an object. and i have only a string name 'checkBoxEnabled' and cannot use it...

how to find an object by name in pyqt? something like? self.GetObjectByName('checkBoxEnabled').checkState()

回答1:

You can use QObject::findChild method. In pyqt it should be written like this:

checkbox = self.findChild(QtGui.QCheckBox, "checkBoxEnabled")

self should be a parent widget of the checkbox.
