[Insight-users] FLTK: fl_file_chooser ??

[Luis Ibanez]

Hi Zein,

Ah!
the beauty of reading the documentation:

http://www . fltk . org/doc-1 . 1/functions . html#fl_file_chooser2

"...The returned value points at a static buffer that
  is only good until the next time fl_file_chooser()
  is called."

------

You may want to do something like

std::string filename1 = fl_file_chooser(...
std::string filename2 = fl_file_chooser(...
std::string filename3 = fl_file_chooser(...

So the actual strings gets copied into a std::string
instead of just being held by a const char *.

Note that there is a new class Fl_File_Chooser
that is probably better than using the fl_file_chooser
function.



Regards,


     Luis
