Ok, i've finally succeed: using «chdir()» is the answer.
For getting it to work, you have to get absolute file path, with
«fl_filename_absolute()».
Here's what i did:
void BrowserCallback(Fl_Widget *w, void *data)
{
Fl_File_Browser *fileb = (Fl_File_Browser *) w;
int selected_file = fileb->value();
const char *path = fileb->text(selected_file);
char absolute_path[2048];
fl_filename_absolute (absolute_path, sizeof(absolute_path), path);
fprintf(stderr,"well, i'm here: %s\n",absolute_path);
if (fl_filename_isdir (absolute_path) ) {
fprintf(stderr,"will go to: %s\n",absolute_path);
chdir (absolute_path);
fileb->load(absolute_path);
}
}
