I'm not sure what you are trying to achieve. If you simply want to add behaviour to a QToolButton then I'd just sub-class it as normal. If you want to add properties then use pyqtProperty(). If you want to create a new Indicator type then I would define an IIndicator interface and implement an adapter from QToolButton to IIndicator. The interface and the adapter together would be pretty much what you have above. If your code sticks to the IIndicator API then it will work with any widget for which a suitable adapter exists.

[PyQt] help with dip and PyQt4 widgets
hi folks, I am creating a composite widget with PyQt4 and Dip, the problem I have is that when I use dip properties for setting PyQt4 properties in the constructor I am getting an error saying that the underlying C++ object has been delete, I think this is due to the way dip works because it call properties methods before the actual Qt4 widget as been created when I pass an initial value in the constructor. When I construct the object with properties initial values and the use the properties accesors to set the value, this doens't happen. So, my question is, which is the right way to construct a custom composite widget with dip? # dip imports from dip.model import Model, Instance, Str # PyQt4 imports from PyQt4 import QtCore, QtGui class Indicator(QtGui.QToolButton, Model): # the indicator identifier, it must be unique for all indicators id = Str() # the indicator text, this text will be shown # beside the icon if one is defined text = Str() # the indicator tooltip tooltip = Str() # the indicator icon icon = Instance(QtGui.QIcon) @id.getter def id(self): print 'getting value' return self.objectName() @id.setter def id(self, id): print 'setting value' self.setObjectName(id) @text.getter def text(self): return self.text() @text.setter def text(self, text): self.setText(text) @tooltip.getter def tooltip(self): return self.toolTip() @tooltip.setter def tooltip(self, tooltip): self.setToolTip(tooltip) @icon.getter def icon(self): return self.icon() @icon.setter def icon(self, icon): self.icon = icon def perform(self): raise NotImplementedError if __name__ == '__main__': app = QtGui.QApplication([]) i = Indicator(text='xxx') i.show() app.exec_() -- Lic.
