EV_setFKeyState |
Function (ROM Call 0xD3) |
Changes the status (active/inactive) of a toolbox in the menu associated with current application.
EV_setFKeyState changes the status of the toolbox Item (0 = first, 1 = second
etc.) which belongs to the menu associated with the current application
(see also MenuTopStat).
State is a Boolean value: when it is TRUE, the toolbox will be
active, and when it is FALSE, the toolbox will be inactive (i.e. it will be
dimmed, and it cannot be selected).
EV_setFKeyState can also force redrawing of the menu after changing state: to do this,
set Boolean parameter Redraw to TRUE.
Avoid menu redraw flicker when enabling/disabling several
function keys by specifying FALSE for redraw in all but the
last call to this routine.

Used by: cmd_disp, cmd_disphome, cmd_input, cmd_inputstr, cmd_output, cmd_pause, cmd_prompt, HomeExecute
