How to use Number Edit Box new value

WendyLou315 — Fri, 07 Jul 2017 15:01:25 GMT

Hello everyone! I feel like such a novice today. I cannot seem to find clear information on how to have Number Edit Box values update a Window, other Number Edit Boxes, and equations when values are changed. My biggest issue is that I have over 30 Number Edit Boxes that feed 2 equations/formulas. Setting the starting values, I have down. If a value is changed, everything else needs to update and I can't figure out what I'm missing and online research has led me no further than when I started.

I have created a small, simple script in hopes of someone here can help me get this understanding through my thick skull.

Thank you all in advance for your knowledge and patience!

doTheMath = function({ val1, val2},
	{result},
	( val1 * val2 ) 
);

var1 = 0;
var2 = 0;

nw = new window( " Testing ",
	<< modal,
	testingVLB = V List Box(
		enterValues = H List Box(
			tbBox1 = Text Box( " Enter Value 1" ),
			nebBox1 = Number Edit Box(var1),
			tbBox2 = Text Box( " Enter Value 2" ),
			nebBox2 = Number Edit Box(var2),
			var1 = nebBox1 << get,
			var2 = nebBox2 << get,
			),
		testResult = doTheMath( var1 , var2),
		tbNothing = Text Box(""),
		if(all(var1!=0, var2!=0), tbResult = Text Box( " Your Result is: " || char( var1 ) || "x" || char( var2 )|| "=" || char( testResult ) ))
	);
);

Try this code. You have to use the << set function() construct for number edit boxes.

doTheMath = function({ val1, val2},
	{result},
	( val1 * val2 ) 
);

var1 = 0;
var2 = 0;

// Save the callback steps as an expression because they're the same for both number edit boxes
num_expr = expr(
	var1 = nebBox1 << get;
	var2 = nebBox2 << get;
	if (!isempty(var1) & !isempty(var2),
		testResult = doTheMath( var1 , var2);
		tbResult << set text(char(testresult));
	);
);


nw = new window( "Testing ", << modal,
	testingVLB = V List Box(
		enterValues = H List Box(
			tbBox1 = Text Box( " Enter Value 1" ),
			nebBox1 = Number Edit Box(var1, 10, << set function(num_expr)),
			tbBox2 = Text Box( " Enter Value 2" ),
			nebBox2 = Number Edit Box(var2, 10, << set function(num_expr)
			),
		),
		tbresult = text box(""),
	),
);

You might want to research the Number Edit Col Box object if you have that many related numeric inputs.
