Descriptions of the Library Routines 2When a window is made active, it receives graphics output (from ARC, LINETO andOUTGTEXT, for example) but is not brought to the foreground and does not have the focus. If awindow needs to be brought to the foreground, it must be given the focus. A window is givenfocus with FOCUSQQ, by clicking it with the mouse, or by performing I/O other than graphics onit, unless the window was opened with IOFOCUS='.FALSE.'. By default, IOFOCUS='.TRUE.',except for child windows opened as unit '*'.The window that has the focus is always on top, and all other windows have their title bars grayedout. A window can have the focus and yet not be active and not have graphics output directed to it.Graphical output is independent of focus.If IOFOCUS='.TRUE.', the child window receives focus prior to each READ, WRITE, PRINT, orOUTTEXT. Calls to graphics functions (such as OUTGTEXT and ARC) do not cause the focus toshift.CompatibilityQUICKWIN GRAPHICS LIBSee Also: “GETACTIVEQQ”, “FOCUSQQ”, “INQFOCUSQQ”, "Using QuickWin" in youruser’s guideSETBKCOLORGraphics Function: Sets the current background color index for both text and graphics. Thisfunction is only available on Windows* systems.Module: USE IFQWINSyntaxresult = SETBKCOLOR (color)color(Input) INTEGER(4). Color index to set the background color to.Results:The result type is INTEGER(4). The result is the previous background color index.SETBKCOLOR changes the background color index for both text and graphics. The color indexof text over the background color is set with SETTEXTCOLOR. The color index of graphics overthe background color (used by drawing functions such as FLOODFILL and ELLIPSE) is set withSETCOLOR. These non-RGB color functions use color indexes, not true color values, and limitthe user to colors in the palette, at most 256. For access to all system colors, useSETBKCOLORRGB, SETCOLORRGB, and SETTEXTCOLORRGB.2-387
