Hey this is a little code i wrote to help beginners with their interfaces. Note that it only works in if its included in a program loop.

+ Code Snippet

function lbutton(x,y,label$)
   ink rgb(20,60,20),0
   box x,y,x+80,y+20
   set text font "Times new roman"
   set text size 18
   if isbetween(mousex(),x,x+80)
      if isbetween(mousey(),y,y+20)
         mouseover=1
         if mouseclick()=1 then bpushed=1
      endif
      sync
   endif
   if mouseover=1 then ink rgb(80,40,40),0 else ink rgb(60,20,20),0

   center text x+40,y,label$
endfunction bpushed

now if you paste that at the bottom of your program or even better, if you have dba pro then create an include file by going to files and add new. Then you use lbutton(xcoordinate,ycoordinate,"button label") !in an if condition only!

eg if lbutton(300,300,"push me")=1 then print "oh yeah". Hope you like it i dont normally give programs away.

eg

+ Code Snippet


sync on
sync rate 30
do
cls
  if lbutton(300,300,"push me")=1
     print "oh yeah"
     suspend for key
     sync
  endif
sync 
loop


function lbutton(x,y,label$)
   ink rgb(20,60,20),0
   box x,y,x+80,y+20
   set text font "Times new roman"
   set text size 18
   if isbetween(mousex(),x,x+80)
      if isbetween(mousey(),y,y+20)
         mouseover=1
         if mouseclick()=1 then bpushed=1
      endif
   endif
   if mouseover=1 then ink rgb(80,40,40),0 else ink rgb(60,20,20),0

   center text x+40,y,label$
endfunction bpushed

edit
ooops forgot you#ll need this function aswell

+ Code Snippet

function isbetween(a,x,y)
   if a>(x-1)
      if a<(y+1)
         between=1
      endif
   endif
endfunction between

   ink rgb(20,60,20),0
   box x,y,x+80,y+20
   set text font "Times new roman"
   set text size 18
   if isbetween(mousex(),x,x+80)
      if isbetween(mousey(),y,y+20)
         mouseover=1
         if mouseclick()=1 then bpushed=1
      endif
   endif
   if mouseover=1 then ink rgb(80,40,40),0 else ink rgb(60,20,20),0

   center text x+40,y,label$
endfunction bpushed

You used the function properly but you,e made a simple error with your program.

You are suspending the program after writing the text , but their is no sync to refresh the screen

+ Code Snippet

sync on
sync rate 30
do
cls
  if lbutton(300,300,"push me")=1
     print "oh yeah"
     sync
     suspend for key
  endif
sync
loop


function lbutton(x,y,label$)
   ink rgb(20,60,20),0
   box x,y,x+80,y+20
   set text font "Times new roman"
   set text size 18
   if isbetween(mousex(),x,x+80)
      if isbetween(mousey(),y,y+20)
         mouseover=1
         if mouseclick()=1 then bpushed=1
      endif
   endif
   if mouseover=1 then ink rgb(80,40,40),0 else ink rgb(60,20,20),0

   center text x+40,y,label$
endfunction bpushed

function isbetween(a,x,y)
   if a>(x-1)
      if a<(y+1)
         between=1
      endif
   endif
endfunction between

I just tried running your example program... (with the other function added, of course!)

Still wont work. Dont know whats wrong, I synced it.

+ Code Snippet

sync on
sync rate 30
do
cls
  if lbutton(300,300,"push me")=1
     print "oh yeah" : sync : wait 100
     suspend for key
  endif
sync
loop


function lbutton(x,y,label$)
   ink rgb(20,60,20),0
   box x,y,x+80,y+20
   set text font "Times new roman"
   set text size 18
   if isbetween(mousex(),x,x+80)
      if isbetween(mousey(),y,y+20)
         mouseover=1
         if mouseclick()=1 then bpushed=1
      endif
   endif
   if mouseover=1 then ink rgb(80,40,40),0 else ink rgb(60,20,20),0

   center text x+40,y,label$
endfunction bpushed

function isbetween(a,x,y)
   if a>(x-1)
      if a<(y+1)
         between=1
      endif
   endif
endfunction between

It detects the click (I put an "end" in it to check just that), but it wont print out the text.

I made a slip up, dont worry too much about the example, as long as you know the button works you can use it in other ways, i just wasn't thinking when i put the example together. I'll explain what's happening and where i went wrong and we can all learn from it.

ok the loops starts by clearing the screen. Then the button is drawn to screen by the button function,and then aided by a sibling function it tests if the mouse is over the button and if the mouse button is pressed.

When the button is pushed it starts a another block of code which is where the problems start.

This block of code prints the text and suspends before the screen is refreshed and as soon as you press the key the loop restarts and clears the screen in the blink of an eye.

heres a better example

+ Code Snippet

do
  cls
  if lbutton(300,300,"push me") then pushed=1
  if pushed=1
    set cursor 300,0
    print "oh yeah"
  endif
  sync
loop

Well, the button function works fine, but I still cant make it work with the printing part. Anyway, its a nice function.

EDIT:

Replace the "print" with an "end", and youll see.
