Jayenkai	Create a neat looking scalable button function that can be reused in lots of place, using only code. ---- The Write Rhyme Print text and draw boxes, draw circles and lines. Use things that within your language you'd find. If you need a package for painting to do it, You haven't quite managed to keep in the spirit. -=-=- ''Load, Next List!''

CodersRule	Jay, is there a way to make those buttons functional? That'd be cool isPushed=Button(x,y,"Lala","lala2") It would draw the button and return a value
Sat, 17 Oct 2009, 06:51
Jayenkai	Yes, it returns out.. So if button(x,y,"TADA")=1 then the mouse is over it, and if =2 then it's clicked.. Forgot to shove that example in there, but it works! -=-=- ''Load, Next List!''

Cower	Mine doesn't do the whole pressed/unpressed result thing (although it'd be easy to put that in there either as a callback, event, or just a result of "If button.Pressed() Then" sort of method.
