How can i make Qpushbutton keep highlight until i deselect object

[nguyen vuducthuy]

Hi there,

I try to create an character picker that when i pressed button i select an object in the scene and it will keep highlight until i deselect that object. This really help me know what i'm selecting.

Thank for your help!

Sound like you want to make the button checkable:

http://doc.qt.io/qt-4.8/qabstractbutton.html#checkable-prop

Then you need to wire up a Maya callback so that the deselection can update the checked state on the button.

        cmds.scriptJob( kill=self.SCRIPT_JOB_NUMBER, force=True )

        super( Picker, self ).closeEvent( event )

def show():

    path = os.path.join(os.path.dirname(__file__), "..", "data", "Bob.json")

    with open(path) as fp:

        d = json.load(fp)

    if d.get("filetype") == "picker_data" and d.get("version") >= 0.1:

        Picker(parent=get_anchor(), data=d).show()
