Example

Example1: Create a cyan colored label that says "100". The widget should have the following specification x=10, x=25, w=40, h=60. It requires a numerics font libary in size 64 to work.

(glgui-label mygui 10 25 40 60 "100" num64.fnt Cyan)

Example2: Create a label "aaaa", which when clicked displays the event type EVENT_BUTTON1UP on the console.

(set! lbl (glgui-inputlabel gui bx by bw bh "aaaa" ascii_18.fnt Red)))
(glgui-widget-set! gui lbl 'onfocuscb (lambda (g wgt type mx my) (display type) (newline)))
