Hi,
I am using fluid to build an app with different widgets showing depending on
compile options passed from the makefile and the code produced is not compiling.
I think fluid does not correctly write the code for the callbacks - if the
class is inside a #if conditional block, then the callback functions should be
also.
Here is an example small fluid file :
//*******************************
# data file for the Fltk User Interface Designer (fluid)
version 1.0107
header_name {.h}
code_name {.cxx}
declblock {\#if 1} {open public after {\#endif}
} {
widget_class widgetclass {open
xywh {349 29 100 100} type Double visible
} {
Fl_Button {} {
label button
callback {printf("Button pushed 1.\\n");}
xywh {10 20 75 40}
}
}
}
declblock {\#if 0} {open public after {\#endif}
} {
widget_class widgetclass {open
xywh {638 56 100 100} type Double visible
} {
Fl_Button {} {
label button
callback {printf("Button pushed 0.\\n");} selected
xywh {10 20 75 40}
}
}
}
//***************************
The header file produced is exactly correct :
//***************************
// generated by Fast Light User Interface Designer (fluid) version 1.0107
#ifndef test_h
#define test_h
#include <FL/Fl.H>
#include <FL/Fl_Group.H>
#include <FL/Fl_Button.H>
#if 1
class widgetclass : public Fl_Group {
public:
widgetclass(int X, int Y, int W, int H, const char *L = 0);
private:
void cb_button_i(Fl_Button*, void*);
static void cb_button(Fl_Button*, void*);
};
#endif
#if 0
class widgetclass : public Fl_Group {
public:
widgetclass(int X, int Y, int W, int H, const char *L = 0);
private:
void cb_button1_i(Fl_Button*, void*);
static void cb_button1(Fl_Button*, void*);
};
#endif
#endif
//***************************
...but the cxx file has all callbacks declared outside the #if blocks, so it
will not compile :
//***************************
// generated by Fast Light User Interface Designer (fluid) version 1.0107
#include "test.h"
void widgetclass::cb_button_i(Fl_Button*, void*) {
printf("Button pushed 1.\n");
}
void widgetclass::cb_button(Fl_Button* o, void* v) {
((widgetclass*)(o->parent()))->cb_button_i(o,v);
}
#if 1
widgetclass::widgetclass(int X, int Y, int W, int H, const char *L)
: Fl_Group(X, Y, W, H, L) {
widgetclass *o = this;
{ Fl_Button* o = new Fl_Button(10, 20, 75, 40, "button");
o->callback((Fl_Callback*)cb_button);
}
end();
}
#endif
void widgetclass::cb_button1_i(Fl_Button*, void*) {
printf("Button pushed 0.\n");
}
void widgetclass::cb_button1(Fl_Button* o, void* v) {
((widgetclass*)(o->parent()))->cb_button1_i(o,v);
}
#if 0
widgetclass::widgetclass(int X, int Y, int W, int H, const char *L)
: Fl_Group(X, Y, W, H, L) {
widgetclass *o = this;
{ Fl_Button* o = new Fl_Button(10, 20, 75, 40, "button");
o->callback((Fl_Callback*)cb_button1);
}
end();
}
#endif
//***************************
The function declaration void widgetclass::cb_button1_i(Fl_Button*, void*)
should be inside a #if(0), meaning that in this example, it will not get
compiled.
Am I using fluid correctly, or is it a bug ? Does anyone have any ideas what I
can do, other than use seperate .fl files and confitionally compile them - I
could do that but it would be messy.
I have tried with 1.1.7 and the latest 1.1.8(r6020). Alternatively, if someone
could point me in the right direction as to how I could fix fluid that would be
great too.
Thanks for any help,
Darren.
