So I figured this would be a simple patch but I can seem to find what is causing me the problem.

Original Code:
void Option::Paint(Draw& w) {
	Size sz = GetSize();
	
	if(!IsTransparent())
		w.DrawRect(0, 0, sz.cx, sz.cy, SColorFace);
	
	Size isz = CtrlsImg::O0().GetSize();
	Size tsz = GetSmartTextSize(label, font);
	int ix = 0;
	int d = tsz.cy >> 1;
	int ty = (sz.cy - tsz.cy) / 2;
	int iy = (tsz.cy - isz.cy) / 2 + ty;

	if(box) {
		ix = d + DPI(4);
		if(tsz.cy > isz.cy) {
			ty = 0;
			iy = (tsz.cy - isz.cy) / 2;
		}
		else {
			iy = 0;
			ty = (isz.cy - tsz.cy) / 2;
		}
	}
	else
	if(!showlabel) {
		ix = (sz.cx - isz.cx) / 2;
		iy = (sz.cy - isz.cy) / 2;
	}
	
	int q = GetVisualState();
	int g = (!notnull || threestate) && IsNull(option) ? CtrlsImg::I_O2
	                                                   : option == 1 ? CtrlsImg::I_O1
	                                                                 : CtrlsImg::I_O0;
	if(switchimage)
		g = option ? CtrlsImg::I_S1 : CtrlsImg::I_S0;
	
	w.DrawImage(ix, iy, CtrlsImg::Get(g + q));
	
	if(showlabel) {
		bool ds = !IsShowEnabled();
		DrawSmartText(w, ix + isz.cx + DPI(2), ty, tsz.cx, label, font,
		              ds || IsReadOnly() ? SColorDisabled : Nvl(color, GetLabelTextColor(this)),
		              VisibleAccessKeys() ? accesskey : 0);
		if(HasFocus())
			DrawFocus(w, RectC(ix + isz.cx + DPI(2), ty - DPI(1), tsz.cx + DPI(3), tsz.cy + DPI(2)) & sz);
	}
	
	if(box) {
		w.Begin();
		w.ExcludeClip(ix - DPI(3), 0, isz.cx + DPI(8) + tsz.cx, tsz.cy);
		PaintLabelBox(w, sz, Null, d);
		w.End();
	}
}


As you can tell it pre gets the size of the image and the label.

It should be just a simple as this to get it on the left side. This i only for testing
void Option::Paint(Draw& w) {
	Size sz = GetSize();

	if(!IsTransparent())
		w.DrawRect(0, 0, sz.cx, sz.cy, SColorFace);

	Size isz = CtrlsImg::O0().GetSize();
	Size tsz = GetSmartTextSize(label, font);
	int ix = 0;
	int d = tsz.cy >> 1;
	int ty = (sz.cy - tsz.cy) / 2;
	int iy = (tsz.cy - isz.cy) / 2 + ty;

	if(box) {
		ix = d + DPI(4);
		if(tsz.cy > isz.cy) {
			ty = 0;
			iy = (tsz.cy - isz.cy) / 2;
		}
		else {
			iy = 0;
			ty = (isz.cy - tsz.cy) / 2;
		}
	}
	else
	if(!showlabel) {
		ix = (sz.cx - isz.cx) / 2;
		iy = (sz.cy - isz.cy) / 2;
	}

	int q = GetVisualState();
	int g = (!notnull || threestate) && IsNull(option) ? CtrlsImg::I_O2
	                                                   : option == 1 ? CtrlsImg::I_O1
	                                                                 : CtrlsImg::I_O0;
	if(switchimage)
		g = option ? CtrlsImg::I_S1 : CtrlsImg::I_S0;

	w.DrawImage(ix + tsz.cx + DPI(2), iy, CtrlsImg::Get(g + q));

	if(showlabel) {
		bool ds = !IsShowEnabled();
		DrawSmartText(w, ix, ty, tsz.cx, label, font,
		              ds || IsReadOnly() ? SColorDisabled : Nvl(color, GetLabelTextColor(this)),
		              VisibleAccessKeys() ? accesskey : 0);
		if(HasFocus())
			DrawFocus(w, RectC(ix, ty - DPI(1), tsz.cx + DPI(3), tsz.cy + DPI(2)) & sz);
	}

	if(box) {
		w.Begin();
		w.ExcludeClip(ix - DPI(3), 0, isz.cx + DPI(8) + tsz.cx, tsz.cy);
		PaintLabelBox(w, sz, Null, d);
		w.End();
	}
}


But this results in anything beyond where the checkbox button image not drawing anything on click

This code shows exactly what I mean when testing a app
void Option::Paint(Draw& w) {
	Size sz = GetSize();

	if(!IsTransparent())
		w.DrawRect(0, 0, sz.cx, sz.cy, SColorFace);

	Size isz = CtrlsImg::O0().GetSize();
	Size tsz = GetSmartTextSize(label, font);
	int ix = 0;
	int d = tsz.cy >> 1;
	int ty = (sz.cy - tsz.cy) / 2;
	int iy = (tsz.cy - isz.cy) / 2 + ty;

	if(box) {
		ix = d + DPI(4);
		if(tsz.cy > isz.cy) {
			ty = 0;
			iy = (tsz.cy - isz.cy) / 2;
		}
		else {
			iy = 0;
			ty = (isz.cy - tsz.cy) / 2;
		}
	}
	else
	if(!showlabel) {
		ix = (sz.cx - isz.cx) / 2;
		iy = (sz.cy - isz.cy) / 2;
	}

	int q = GetVisualState();
	int g = (!notnull || threestate) && IsNull(option) ? CtrlsImg::I_O2
	                                                   : option == 1 ? CtrlsImg::I_O1
	                                                                 : CtrlsImg::I_O0;
	if(switchimage)
		g = option ? CtrlsImg::I_S1 : CtrlsImg::I_S0;

  if(option != 1) {
		w.DrawRect(0, 0, sz.cx, sz.cy, Red());
  } else {
		w.DrawRect(0, 0, sz.cx, sz.cy, Green());
  }

	if(showlabel) {
		bool ds = !IsShowEnabled();
		DrawSmartText(w, ix, ty, tsz.cx, label, font,
		              ds || IsReadOnly() ? SColorDisabled : Nvl(color, GetLabelTextColor(this)),
		              VisibleAccessKeys() ? accesskey : 0);
		if(HasFocus())
			DrawFocus(w, RectC(ix, ty - DPI(1), tsz.cx + DPI(3), tsz.cy + DPI(2)) & sz);
	}

	if(box) {
		w.Begin();
		w.ExcludeClip(ix - DPI(3), 0, isz.cx + DPI(8) + tsz.cx, tsz.cy);
		PaintLabelBox(w, sz, Null, d);
		w.End();
	}
}


There is something choosing where the control painting will get updated and only painting that part. I have no clue what code is doing that.

Never mind. I think it is in this

void Option::RefreshPush() {
	if(box)
		Refresh(0, 0, GetSize().cx, GetSmartTextSize(label, font).cy);
	else
	if(showlabel)
		Refresh(0, 0, CtrlsImg::O0().GetSize().cx, GetSize().cy);
	else
		Pusher::RefreshPush();
}

This is of it working with label to the left. I am going to patch mine too support left and right labels

void Option::RefreshPush() {
	if(box)
		Refresh(0, 0, GetSize().cx, GetSmartTextSize(label, font).cy);
	else
	if(showlabel)
		Refresh(GetSmartTextSize(label, font).cx + DPI(2), 0, CtrlsImg::O0().GetSize().cx, GetSize().cy);
	else
		Pusher::RefreshPush();
}

void Option::Paint(Draw& w) {
	Size sz = GetSize();

	if(!IsTransparent())
		w.DrawRect(0, 0, sz.cx, sz.cy, SColorFace);

	Size isz = CtrlsImg::O0().GetSize();
	Size tsz = GetSmartTextSize(label, font);
	int ix = 0;
	int d = tsz.cy >> 1;
	int ty = (sz.cy - tsz.cy) / 2;
	int iy = (tsz.cy - isz.cy) / 2 + ty;

	if(box) {
		ix = d + DPI(4);
		if(tsz.cy > isz.cy) {
			ty = 0;
			iy = (tsz.cy - isz.cy) / 2;
		}
		else {
			iy = 0;
			ty = (isz.cy - tsz.cy) / 2;
		}
	}
	else
	if(!showlabel) {
		ix = (sz.cx - isz.cx) / 2;
		iy = (sz.cy - isz.cy) / 2;
	}

	int q = GetVisualState();
	int g = (!notnull || threestate) && IsNull(option) ? CtrlsImg::I_O2
	                                                   : option == 1 ? CtrlsImg::I_O1
	                                                                 : CtrlsImg::I_O0;
	if(switchimage)
		g = option ? CtrlsImg::I_S1 : CtrlsImg::I_S0;

	w.DrawImage(ix + tsz.cx + DPI(2), iy, CtrlsImg::Get(g + q));

	if(showlabel) {
		bool ds = !IsShowEnabled();
		DrawSmartText(w, ix, ty, tsz.cx, label, font,
		              ds || IsReadOnly() ? SColorDisabled : Nvl(color, GetLabelTextColor(this)),
		              VisibleAccessKeys() ? accesskey : 0);
		if(HasFocus())
			DrawFocus(w, RectC(ix, ty - DPI(1), tsz.cx + DPI(3), tsz.cy + DPI(2)) & sz);
	}

	if(box) {
		w.Begin();
		w.ExcludeClip(ix - DPI(3), 0, isz.cx + DPI(8) + tsz.cx, tsz.cy);
		PaintLabelBox(w, sz, Null, d);
		w.End();
	}
}

I did a quick hack to Option called it eOption just as an example. It allows left oriented label and also allows adding space between the image and the label.

Sorry the quick hack had bugs in it. It was late and I was getting off work. Here is a fully working example in project form
