Regards. 1- I create a widget ( a button, for example ) 2- I change the font of that widget 3- I change the caption of widget ( #contents: asString ), then the font returns to original font widget ( the font for buttons of current UITheme instance) Is normal that behavior or is a bug? if not bug, exists some way for avoid that? Thanks for the answer :) -- View this message in context: http://n4.nabble.com/Polymorph-font-behavior-tp1838643p1838643.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
