Gui & scroll bars

[just me]

Code: Select all

		// MSDN: "The AdjustWindowRectEx function does not take the WS_VSCROLL or WS_HSCROLL styles into
		// account. To account for the scroll bars, call the GetSystemMetrics function with SM_CXVSCROLL
		// or SM_CYHSCROLL."
		if (style & WS_HSCROLL)
			width += GetSystemMetrics(SM_CXHSCROLL);
		if (style & WS_VSCROLL)
			height += GetSystemMetrics(SM_CYVSCROLL);

I'm wondering why the width of the Gui is increased for WS_HSCROLL and the height for WS_VSCROLL. Is this really intended, and if so, why?

Also, there's a discrepancy between the comment and the code.

I believe that:
- a horizontal scroll bar means the width needs to increase to eliminate the need for it
- a vertical scroll bar means the height needs to increase to eliminate the need for it

The only reason for using WS_HSCROLL/WS_VSCROLL is that you want to show scroll bars.
