| Something that's been bothering me for some time: the two boxes of the Fl_Value_Slider are not correctly aligned. The Fl_Slider box is always drawn in full width or height, disregarding the size of the value box. The problem is in Fl_Slider::draw_bg():
void Fl_Slider::draw_bg(int X, int Y, int W, int H) {
if (!(damage()&FL_DAMAGE_ALL)) { // not a complete redraw
fl_push_clip(X, Y, W, H);
draw_box();
fl_pop_clip();
} else {
draw_box();
}
...
In this function, the check for DAMAGE_ALL is redundant (as this is already handled in draw()), yet it causes the ill-sized slider-box to be drawn on top of the correctly sized slider-box in Fl_Value_Slider::draw(). Changing the code to the following fixes this, while drawing of other sliders remains intact:
void Fl_Slider::draw_bg(int X, int Y, int W, int H) {
fl_push_clip(X, Y, W, H);
draw_box();
fl_pop_clip();
...
