i write a program using resize function. but the widget does not being resized
why?
#include <fltk/Button.h>
#include <fltk/Group.h>
void button_cb (Widget *w, void* v);
void input_cb (Widget *w, void* v);
class gp : public fltk::Group {
public:
fltk::Button *b;
gp(int x, int y, int w, int h, char*l=0):fltk::Group(x,y,w,h,l,true){
box(THIN_DOWN_BOX);
b = new Button(10,20,40,40,"OK");
b->callback(button_cb, (void*)this);
}
~gp(){}
};
class g : public gp {
public:
fltk::Input *input;
g(int x, int y, int w, int h, char*l=0):gp(x,y,w,h,l){
//box(THIN_DOWN_BOX);
input = new Input(100,20,40,40,"OK");
input->hide();
//input->box(THIN_DOWN_BOX);
input->callback(input_cb, (void*)this);
input->when(WHEN_ENTER_KEY_ALWAYS);
//input->parent(this);
add(input);
end();
}
~g(){}
};
void input_cb (Widget *w, void* v) {
g* s = (g*)v;
//s->input->value("sss\n");
}
void button_cb (Widget *w, void* v) {
g* s = (g*)v;
s->input->resize(20,100, 40, 120);
//s->input->set_damage(DAMAGE_ALL);
s->input->show();
//s->update_child((Widget&)*(s->input));
//((g*)s->input)->value("sss\n");
}
int main(){
Window window(w_window, h_window, "hhh");
g ge(20, 20, window.w()-80, window.h()-80, 0);
window.add(ge);
window.end();
//window.resizable(table);
window.show();
return run();
}
