C++ (Cpp) Fl_Scrollbar::value Examples

Example #1

void Fl_MIDIKeyboard::hscrollbar_cb(Fl_Widget* w, void*) {      // called only if MKB_HORIZONTAL
    Fl_MIDIKeyboard* mk = (Fl_MIDIKeyboard*)(w->parent());
    Fl_Scrollbar* scbar = (Fl_Scrollbar*)w;
    mk->position((int)(scbar->value()), mk->yposition());       // do the scrolling
    mk->visible_keys();                                         // set the visible keys range
}

Example #2

void Fl_MIDIKeyboard::scrollbar_cb(Fl_Widget* w, void*) {       // called only if MKB_VERTICAL
    Fl_MIDIKeyboard* mk = (Fl_MIDIKeyboard*)(w->parent());
    Fl_Scrollbar* scbar = (Fl_Scrollbar*)w;
    mk->position(mk->xposition(), (int)(scbar->value()));       // as above
    mk->visible_keys();
}
