Look at this example:
|RequestTimedRefresh( 1 );
LeftButton = GetCursorMouseButtons() & 1;
reset = GetCursorMouseButtons() &4 ; // middle button pressed
numClicks = Nz( StaticVarGet( "counter" ) );
*if* ( leftButton )
StaticVarSet( "counter", numClicks + 1 );
*if* (reset )
{
StaticVarSet( "counter" ,0);
* Title* = "Counter Reseted !" ;
}
*else*
*Title* = "Clicks Counter: " + StaticVarGet( "counter" );|

Hello,
I would like to decrease Myparam of 0.25 on each clic inside the red button.
I complicated with static var but Myparam comes back to 5 as it is declared at
the beginning of the formula.
How to decrease a var with a GFX button ?
To give an idea of what I want to do , once this point solved, my next step
will be to increase of 0.25 the same Myparam with a Plus button to adjust a
Fibonacci step. I will add Fibonacci code at the very end.
AB parameters windows lacks some ergonomics in real time.
I draw the buttons in the upper right side, after the bars, as quote marker
will not be activate.
Thanks for the help
Best regards
