Action

draw a row of keys.

Syntax

CmdKeys x, y, w ,h, font, options, char

x	x-coordinate of keys top-left, in pixels
y	y-coordinate of keys top-left, in pixels
w	The width of the keys
h	The height of the keys
font	Bitmap handle to specify the font used in key label. The valid range is from 0 to 31
options	By default the keys are drawn with a 3D effect and the value of option is zero. OPT_FLAT removes the 3D effect. If OPT_CENTER is given the keys are drawn at minimum size centered within the w x h rectangle. Otherwise the keys are expanded so that they completely fill the available space. If an ASCII code is specified, that key is drawn 'pressed' - i.e. in background color with any 3D effect removed.
char	Key labels, one character per key. The TAG value is set to the ASCII value of each key, so that key presses can be detected using the REG_TOUCH_TAG register.

The gap between keys is 3 pixels.

For OPT_CENTERX case, the keys are (font width + 1.5) pixels wide ,otherwise keys are sized to fill available width.
