Update a List Box Based on a Combo Box Selection

Ksrzg01

Hello all,

 

So I have a few lists, in this case fruit and vegetables, and based on my selection on the combo box I would like to populate the list box with the new list. For example, if I have "fruit" selected, I want the list box to display oranges, apples, and grapes. The script I have works, but it doesnt evaluate the list AND I also do not want it to keep appending the list box with my selection. Is there a way around this?

 

 

TestArray = {"Fruit", "Vegetables"}; //my list of 'stuff'
Fruit = {"Oranges", "Apples", "Grapes"};
Vegetables = {"Corn", "Squash", "Eggplants"};


nw = New Window( "Sample",
	<<Modal,
	vlb = H List Box(
		cb = Combo Box(
			TestArray,
			tb2 << Append(cb << Get Selected);
		),
		tb2 = List Box()
	)
);

Thanks!

The main issue is that what is returned from the 

cb << Get Selected

is not a variable name, as you were wanting it to be, but rather a string, "Fruit" or "Vegetables".  That is, the names of the 2 list are Fruit and Vegetables, not "Fruit" and "Vegetables".

Below is a script that works the way you want.  There are other ways to do this, that others may want to contribute

Names Default To Here( 1 );
TestArray = {"Fruit", "Vegetables"}; //my list of 'stuff'
Fruit = {"Oranges", "Apples", "Grapes"};
Vegetables = {"Corn", "Squash", "Eggplants"};


nw = New Window( "Sample",
	<<modal,
	vlb = H List Box(
		cb = Combo Box(
			TestArray,
			tb2 << remove all;
			If( (cb << Get Selected) == "Fruit",
				tb2 << Append( Fruit ),
				tb2 << Append( Vegetables )
			);
		),
		tb2 = List Box()
	)
);
