This command tests the
buttons to see if one was clicked in. If one was clicked in then
it returns the index in buttonHit, if not, then it returns
-1.
This command is different
to Wait Button Click because it does not wait until a button
is clicked in. This means that using this command other operations
can be performed. e.g.
' Define
buttons up here
...
int buttonHit=-1
while buttonHit=-1
buttonHit=Poll Button Click
' Do other
operations
...
Draw Frame
wend
' Test
the value of which button was hit
...
NB: You must call the 'Draw Frame' command from
the loop that calls 'Poll Button Click' for the buttons to react to the mouse passing over
them.
