Show information on mouse hover

Hello Everyone,
I have small objects on screen with information in it, I want to show that information when use hover over that component and when they remove mouse from that component that information will go away. I tried using mouse entered and gui.messagebox but it will have to be closed manually. Any idea to achieve this?
Thank you.

Is this for Vision or Perspective? system.gui.messageBox will only work in Vision so I assume you must be in Vision?

Most, if not all, components in vision have a Mouseover Text property that will do this.

Just type in the text, or bind the mouseover text property to a value. You can even add html tags to make the text really big.

<html><font size = 12>Hello
