Width of a button box

[#1]

How can I reduce the width of a button box via JSL? I would like to create a very small button containing only a "+" sign.The default width of 

Button Box("+")

resulting in

is optically too large for my purpose. I was not able to find a way to control its size.

Thanks for any hint.

With a button box() I believe the best you can do, is to use the Icon functionality that it has, and to use the icon named "Formula"

Names Default To Here( 1 );
New Window( "Example", ex = Button Box( "" ) );
ex << Set Icon( "Formula" );

Thanks. I might use a custom icon with plainer style instead. That's a good solution to achieve a smaller button size.

FormulaPlus, WinToolsCrosshair, DebuggerAddWatch

See Help > JMP Documentation Library > JSL Syntax Reference and look up "button box."

Try the WinToolsCrosshair icon - it's thinner.  Only works on Windows though.

Names Default To Here( 1 );
New Window( "Example", 
	ex = Button Box("", << Set Icon("WinToolsCrosshair"))
);

Also, check out the very nice Built-in icons addin https://community.jmp.com/t5/JMP-Add-Ins/Built-In-JMP-Icons/ta-p/42251

There are many different plus signs.

Thanks for all comments and hints.

The built-in icons are all too large for my purpose. I use a custom icon with plainer style instead:

bb = Button Box ("");
bb << Set Icon( "plus.png" );

with this small plus.png icon    results in quite exactly the small "add" buttons I need in my list:
