I would like EditFields to change color when they have focus (as they do when they have invalid data). However, because so many controls are derived from EditField it is unpleasant to modify the Paint method.

Instead I have given the control a simple Chameleon style that functions identically to the original but exposes a Color that can be set when it has focus. My version is attatched.

Would it be possible to have something similar incorporated into the Upp::CtrlLib package so that I don't have to update the source myself?

OK. I did two changes:

Invalid color - moved that Blend to default style, so that in Paint no blending, just invalid is used.

Renamed hligght to select.

Currently disabled EditFields show pink if they have invalid data, which doesn't make sense to me, so I've added an extra check (and it now caches the result of IsShowEnabled since it's called 5 times):

void EditField::Paint(Draw& w)
{
	Size sz = GetSize();
	bool f = HasBorder();
	bool enabled = IsShowEnabled();
	const EditField::Style *st = style ? style : &StyleDefault();
	Color paper = enabled && !IsReadOnly() ? (HasFocus() ? st->focus : st->paper) : st->disabled;
	if(nobg)
		paper = Null;
	Color ink = enabled ? st->text : st->textdisabled;
	if(convert && enabled && convert->Scan(text).IsError())
		paper = st->invalid;
	int fcy = font.Info().GetHeight();
	int yy = GetTy();
	w.DrawRect(0, 0, 2, sz.cy, paper);
	w.DrawRect(0, 0, sz.cx, yy, paper);
	w.DrawRect(0, yy + fcy, sz.cx, sz.cy - yy - fcy, paper);
	w.DrawRect(sz.cx - 2, 0, 2, sz.cy, paper);
	w.Clipoff(2, yy, sz.cx - 4, fcy);
	int x = -sc;
	if(IsNull(text) && !IsNull(nulltext)) {
		const wchar *txt = nulltext;
		Paints(w, x, fcy, txt, nullink, paper, nulltext.GetLength(), false);
	}
	else {
		const wchar *txt = text;
		int l, h;
		if(GetSelection(l, h)) {
			Paints(w, x, fcy, txt, ink, paper, l, password);
			Paints(w, x, fcy, txt, enabled ? st->selectedtext : paper,
			                       enabled ? st->selected : ink, h - l, password);
			Paints(w, x, fcy, txt, ink, paper, text.GetLength() - h, password);
		}
		else
			Paints(w, x, fcy, txt, ink, paper, text.GetLength(), password);
	}
	w.DrawRect(x, 0, 9999, fcy, paper);
	w.End();
//	w.DrawRect(dropcaret, LtBlue());
	DrawTiles(w, dropcaret, CtrlImg::checkers());
}

Could this be added to Uppsrc please?

Yes. The base code has changed meanwhile, but I hope I have preserved the spirit of your change;)
