Hide Combo Box Menu Item

[d.healey]

Could we have a feature to hide a menu item (if we don't already). I can currently think of two uses for this:

• Adjusting one control on a UI changes the displayed options in a menu.
• All of your menu items are numbers and you want them to correspond to the getValue() number but you don't want to start from 0 or you want to skip values.

To clarify the second use case a bit more lets say you want a menu that contains CC numbers 1 - 100 but missing out 64, so I'd do something like this:-

var menuItems = [];

for (i = 1; i < 100; i++)
{
	if (i == 64) continue
	menuItems[i] = i;
}

menuItems = menuItems.join("\n");
myComboBox.set("items", menuItems);

The problem is I will end up with a menu items string like this

undefined/n1/n2/n3/n4/n5/n6/n7/n8/n9/n10/n11/n12/n13/n14/n15/n16/n17/n18/n19/n20/n21/n22/n23/n24/n25/n26/n27/n28/n29/n30/n31/n32/n33/n34/n35/n36/n37/n38/n39/n40/n41/n42/n43/n44/n45/n46/n47/n48/n49/n50/n51/n52/n53/n54/n55/n56/n57/n58/n59/n60/n61/n62/n63/undefined/n65/n66/n67/n68/n69/n70/n71/n72/n73/n74/n75/n76/n77/n78/n79/n80/n81/n82/n83/n84/n85/n86/n87/n88/n89/n90/n91/n92/n93/n94/n95/n96/n97/n98/n99

I would like to hide the undefined menu items so that the user can't see them but it doesn't affect the order so that when I select option 8 and use getValue() the value will be 8.

I can't think of a way to do this without hacking something, but you can use the current text as value:

var menuItems = [];

for (i = 1; i < 100; i++) menuItems.insert(-1, i);
menuItems.remove(64);

const var ComboBox = Content.addComboBox("ComboBox", 59, 12);

menuItems = menuItems.join("\n");
ComboBox.set("items", menuItems);

function onNoteOn() {}
function onNoteOff() {}
function onController() {}
function onTimer() {}
function onControl(number, value)
{
	Console.print(parseInt(ComboBox.getItemText()));
}

Ah that's a good idea!
