Was toying with some code which happened to set the tooltip font to FL_FREE_FONT. When attempting to show the tooltip, I got a crash in Fl_Xlib_Graphics_Driver::get_font_name - as the font name is NULL.
Linux Mint 20.2, FLTK 1.4 built from source a couple of weeks ago.
To be expected?
Hi Kevin,
Yes, as Albrecht says, FL_FREE_FONT gives the index for the first unassigned (thus free) font entry.
So you can assign your own font to that index (or higher.)
But if you use it before a face is assigned to it, then it will be null... -- IanFrom my Fairphone FP3
