Hi Guys
I am doing something weird.
I want to mix ncurses and xforms.
I can obtain the window ID that the ncurses program is running in. I
wanted to override the FL_FORM struct so that the window ID is the
terminal window's ID.
I tracked Window in the FL_FORMS struct on line 896 to window(lowercase)
and then this back to line 96 in X.h
Window is a typedef of XID on line 66 of X.h
XID is type unsigned long.
I tried to hack arrows.c from demos like this:
int
main( int argc,
char * argv[ ] )
{
FL_FORM *form;
FL_OBJECT *obj;
fl_initialize( &argc, argv, "FormDemo", 0, 0 );
form = fl_bgn_form( FL_FLAT_BOX, 400, 400 );
form->window = 83886089;
printf("first time, window is is %lu \n", form->window) ;
obj = fl_add_button( FL_NORMAL_BUTTON, 50, 250, 100, 100, "@1" );
fl_set_object_lcolor( obj, FL_BLUE );
obj = fl_add_button( FL_NORMAL_BUTTON, 150, 150, 100, 100, "@square" );
fl_set_object_lcolor( obj, FL_GREEN );
fl_end_form( );
fl_show_form( form, FL_PLACE_ASPECT, FL_TRANSIENT, "Buttons" );
while ( fl_do_forms( ) != obj )
/* empty */ ;
printf("second time, window is is %lu \n", form->window) ;
fl_finish( );
return 0;
}
The window ID in the second printf statement does not match the one I
assigned to it but the first one does.
Am I close? Is there a better way to do this?
Thanks-Patrick
