hello,
ive made some custom Fl_Output_Value. basically i just
replaced format() from Fl_Valuator (see draw() of
Fl_Value_Output below)
void Fl_Value_Output::draw() {
Fl_Boxtype b = box() ? box() : FL_DOWN_BOX;
int X = x()+Fl::box_dx(b);
int Y = y()+Fl::box_dy(b);
int W = w()-Fl::box_dw(b);
int H = h()-Fl::box_dh(b);
if (damage()&~FL_DAMAGE_CHILD)
draw_box(b, color());
else {
fl_color(color());
fl_rectf(X, Y, W, H);
}
char buf[128];
format(buf); // replaced
fl_color(active_r() ? textcolor() :
fl_inactive(textcolor()));
fl_font(textfont(), textsize());
fl_draw(buf,X,Y,W,H,FL_ALIGN_LEFT);
}
so, i subclassed Fl_Value_Output and redefined the draw()
function (is redefined the correct term?). in that draw
function however i only change the format(buf); line to
call my function. how ugly! now, is it possible to
"redefine" redraw(); (derived from Fl_Valuator) in my
subclass (derived from Fl_Value_Output, derived from
Fl_Valuator) instead of draw()?
like this:
class Glide_Rate: public Fl_Value_Output
{
void format(const char* buf);
public:
Glide_Rate(int x, int y, int w, int h, char const* label = 0) :
Fl_Value_Output(x, y, w, h, label)
{
;
}
};
? jan
