Still not quite sure here.
I checked the documentation (Color & Font functions) and could only find fl_font which seemed to be part of an fl_draw package.
I expected calls for things like
win2_flag1->textsize(11); ... but globally
win2_flag1->labelsize(11); .......but globally
etc...

Do they exist ?

I don't know what would be win2_flag1 in your mind.

Among possible things, there are :

For any given pointer to n Fl_Widget (e.g., Fl_Button *) widget

widget->labelsize(size); // sets the widget's label size

widget->labelfont(fontnumber); // sets the widget's label font

widget->labelcolor(color); // sets the widget's label color

widget->label(text); // sets the widget's label text

But this applies to the given widget only.

Functions with effects on all widgets were described in my previous post.
A key thing is these functions must be used before widgets are created.
A simple way to achieve that is to begin your main() with

fl_open_display(); // needs #include <FL/platform.H>

and then use the global-effect function calls or change the value of public global variables.
