GUILayout.BeginScrollView

Parámetros

Valor de retorno

Vector2 The modified scrollPosition. Feed this back into the variable you pass in, as shown in the example.

Descripción

Begin an automatically laid out scrollview.

Automatically laid out scrollviews will take whatever content you have inside them and display normally. If it doesn't fit, scrollbars will appear. A call to BeginScrollView must always be matched with a call to EndScrollView.


Scroll View in the Game View..

	// The variable to control where the scrollview 'looks' into its child elements.
	var scrollPosition : Vector2;

	// The string to display inside the scrollview. 2 buttons below add & clear this string.
	var longString = "This is a long-ish string";

	function OnGUI () {	
		// Begin a scroll view. All rects are calculated automatically - 
		// it will use up any available screen space and make sure contents flow correctly.
		// This is kept small with the last two parameters to force scrollbars to appear.
		scrollPosition = GUILayout.BeginScrollView (
			scrollPosition, GUILayout.Width (100), GUILayout.Height (100));
		
		// We just add a single label to go inside the scroll view. Note how the
		// scrollbars will work correctly with wordwrap.
		GUILayout.Label (longString);
		
		// Add a button to clear the string. This is inside the scroll area, so it
		// will be scrolled as well. Note how the button becomes narrower to make room
		// for the vertical scrollbar
		if (GUILayout.Button ("Clear"))
			longString = "";
		
		// End the scrollview we began above.
		GUILayout.EndScrollView ();
		
		// Now we add a button outside the scrollview - this will be shown below
		// the scrolling area.
		if (GUILayout.Button ("Add More Text"))
			longString += "\nHere is another line";
	}
