How do you/can you set up a tool tip for a GUI texture?

Unity Engine
1

As per title or do you need to do a mouse contains and display your own label?

2

Does anyone think it isn’t possible?

Its possible.
Instead of firing in strings / images to gadgets, you use a GUIContent - the gui content objects transfer the tooltip along the title of button or its image for you :slight_smile: (I guess you might always have asked yourself why GUIContent is there if you can use string and image directly)

guicontent is capable of a few other things too

If you dont like GUIContent’s tooltip, you could always make a class inherit from GUITexture and in the OnMouseEnter function, make a custom tooltip pop up yourself

This worked nicely until I realised I can’t move the tooltip.

for example

if (GUI.Button (Rect (5,5,100, 100), GUIContent (“ButtonA”, “Button A tip”),myStyle))
{
//code here
}
GUI.Label (Rect (5,5,100, 100), GUI.tooltip,tooltipStyle);

if (GUI.Button (Rect (50,5,100, 100), GUIContent (“ButtonB”, “Button B tip”),myStyle))
{
//code here
}
GUI.Label (Rect (50,5,100, 100), GUI.tooltip,tooltipStyle);

Now tooltip B is fine but tooltip A shows in both places. How do I get around this? I want a number of tooltips and for them to move.

edit:
I ended up using the inputposition of the mouse for x and y. I wonder if there is a better way?

If you don’t like the built in tooltip behavior, you could roll something custom like this (untested):

string tooltip = "";


void Tooltip (Rect rect, string lastTooltip)
{
	if (rect.Contains (Event.current.mousePosition))
	{
		tooltip = lastTooltip;
	}
}


void TooltipLastLayout (string lastTooltip)
{
	Tooltip (GUILayoutUtility.GetLastRect (), lastTooltip);
}


void OnGUI ()
{
	tooltip = "Hover a label to see its tooltip";
	
	GUILayout.BeginHorizontal ();
		GUILayout.BeginVertical ();
			GUILayout.Label ("Label 1");
			TooltipLastLayout ("Label 1 tooltip");
			GUILayout.Label ("Label 2");
			TooltipLastLayout ("Label 2 tooltip");
			GUILayout.Label ("Label 3");
			TooltipLastLayout ("Label 3 tooltip");
		GUILayout.EndVertical ();
		GUILayout.Label (tooltip);
	GUILayout.EndHorizontal ();
}
