The PUSHBOX resource-definition statement creates a push-box control, which is identical to a PUSHBUTTON, except that it does not display a button face or frame; only the text appears.
PUSHBOX text, id, x, y, width, height [[, style [[, extended-style]]]]
If you do not specify a style, the default style is BS_PUSHBOX | WS_TABSTOP.
For more information on the text, id, x, y, width, height, style, and extended-style parameters, see Common Control Parameters.
