How to change widget shape in QtDesigner ?

[giorgik]

Finally I managed to compile the test program for the led plugin and to be able to vary the properties of the plugin within the Qt Designer, both for the shape field and for the color field, which now finally can vary the shape and color of the led on the form in Qt Designer as I wanted. This result was obtained thanks to the constant help of d_stranz in the post "AnalogClock::staticMetaObject': definition of dllimport static data member not allowe".
