BGCOLOUR_QL [#ch,] colour


SMSQ/E v2.98+

It is possible under the latest version of SMSQ/E to set a ‘wallpaper’ - this is an image which covers the whole of the available screen (in any resolution) and which forms a background for any programs which may be running. Normally, this would appear as a black area of the screen.

A valid window channel must be open, default #1 (or #0 on a SBASIC with only #0 open), although one may also be supplied as #ch. BGCOLOUR_QL allows you to specify any standard QL colour - the parameters allowed are the same as for the INK command (in either Standard QL Colour Mode or COLOUR_QL mode), which thus allows for you to specify composite colours as well as palette mapped colours with PALETTE_QL.


BGCOLOUR_QL 2,7 - sets a red and white checkerboard pattern.


Refer to Appendix 16 and INK for more details on colours.

BGCOLOUR_24 is similar.

BGIMAGE may be used to set a screen image as the wallpaper.
