Description
Visualises a list of strings or objects overriding ToString and returns the item selected by the user.
Component code
<csharp> public static object SelectList( ICollection list, object selected, GUIStyle defaultStyle, GUIStyle selectedStyle ) { foreach( object item in list ) { if( GUILayout.Button( item.ToString(), ( selected == item ) ? selectedStyle : defaultStyle ) ) { if( selected == item ) // Clicked an already selected item. Deselect. { selected = null; } else { selected = item; } } }
return selected; }
public delegate bool OnListItemGUI( object item, bool selected, ICollection list );
public static object SelectList( ICollection list, object selected, OnListItemGUI itemHandler ) { ArrayList itemList;
itemList = new ArrayList( list );
foreach( object item in itemList ) { if( itemHandler( item, item == selected, list ) ) { selected = item; } else if( selected == item ) // If we *were* selected, but aren't any more then deselect { selected = null; } }
return selected; } </csharp>
Usage
<csharp> currentSeletion = SelectList( myList, currentSelection, GUI.skin.GetStyle( "Button" ), GUI.skin.GetStyle( "Label" ) ); </csharp>
In this example, myList could be an ArrayList of strings or instances of your own type, returning the desired list label in ToString.
