Popup menu closing on title

[ddyer0]

If I construct a combo box with a title component, clicking on that title closes the combo box without
any of the subitems being triggered. This is generally undesirable - the title looks like any other item
and it's an easy accidental target.

I've tried several kludgey workarounds but found no way to make the title area into neutral territory where
clicks are ignored.

What's a combo box with a title component?

[ddyer0]

create a menu with a title argument, show it as a popup combo box. The title becomes the zero'th element, which can't
be selected, but clicking still closes the menu.

The "game name" at the top is a title. It's not an item that can be clicked on, but if you do the popup closes. I've recently modified it to make it visually distinct from the rest of the menu, which helps, but I wish that I could arrange that clicking on it does not close the menu.

What's the code that creates that?

[ddyer0]

the key is new Menu("title") ... then new Combox(menu).show()
i can construct an executable sample.
the main thing is that any pointer hit on the box results in it being closed, regardless
if the pointer hit anything.

What's "Menu"? We don't have menu as an argument for ComboBox: https://github.com/codenameone/CodenameOne/blob/master/CodenameOne/src/com/codename1/ui/ComboBox.java#L146-L169

This is approximately what I'm using

	 	ComboBox<String> m = new ComboBox("This is a Title");
	 	m.addItem("item 1");
	 	m.addItem("item 2");
	 	Dimension sz = m.getPreferredSize();
	 	m.setSize(sz);
	 	m.setX(100);
	 	m.setY(100);
	 	t.form.add(m);
	 	m.setVisible(true);
	 	m.pointerReleased(100,100);

I'd like the thing I specified as a title to be not clickable, and attempting to click on it to not cause the dialog to close.

setSize/X/Y etc. is wrong. that's not how Codename One works. That is not a title. The fact that it's rendered differently isn't explained by your code since it's just the first item in a list and then you add additional items. This code is equivalent to:

ComboBox<String> m = new ComboBox("This is a Title", "Item 1", "Item 2");

Only your version fires lots of change events while doing the same thing. See https://github.com/codenameone/CodenameOne/blob/master/CodenameOne/src/com/codename1/ui/List.java#L2194 and https://github.com/codenameone/CodenameOne/blob/master/CodenameOne/src/com/codename1/ui/list/DefaultListModel.java#L179

If you want something similar to a title we have the popupTitleBool theme constant you can set to true. You then need to use setLabelForComponent to define the label of the title. It's in the JavaDocs of the component.

This is a toy example, not representative the way I actually generate these menus.
You've convinced me that it's not worth pursuing this kind of feature for combo boxes.
