...some time necessary to cut it out of the major project, to understand, what I thought 7 years ago and to make an example. Basics: The code is ment to change labelfont/ labelsize and textfont/textsize of FLTK windows, this means four different values to be changeable. It's a problem, that basic class Fl_Widget only provides methods to change labels, not the equivalent methods to change texts. The problem was solved by dynamic casts for finding out, whether there are text methods, but for FLTK 1.3 I would recommend to add virtual methods textsize() and textfont() to Fl_Widget. When displaying the code it might be interesting to know, that I'm using tab width of 3. Methods: By inheritance it is easy to use the code for adding the functionality to existing applications. For download, all of the code is inside of http://www.tantec.de/komponenten/FLTK/font_size/ Please take care of Readme.txt and I need to point out, that I didn't succeed in creating a makefile working for windows. There are lots of german words and comments, but I think, we can start diskussion without need to translate it first. Missing explanations will come when up to date - for the moment I'm trying to start the existing stuff... ;o) Also saving and restore of settings is not mentioned. For use in FLTK it might be more easy, but I think, this is a good point to start. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
