GuiObject

GuiObject is an abstract class (much like BasePart) for a 2D user interface object. It defines all the properties relating to the display of a graphical user interface (GUI) object such as GuiObject/Size and GuiObject/Position. It also has some useful read-only properties like GuiObject/AbsolutePosition, GuiObject/AbsoluteSize, and GuiObject/AbsoluteRotation. It should be noted that GuiObject can have negative sizes and render normally, though GuiObject/AnchorPoint ought to be used to better control rendering.

To manipulate the layout of a GuiObject in special ways, you can use a UIComponent class such as UIListLayout, UIPadding or UIScale.

This class defines very simple animation methods: GuiObject/TweenPosition, GuiObject/TweenSize and GuiObject/TweenSizeAndPosition are good alternatives to TweenService for beginners.

GuiObject also defines events for user input like GuiObject/MouseEnter, GuiObject/TouchTap, GuiObject/InputBegan, GuiObject/InputChanged and GuiObject/InputEnded. The last three of these mimic the events of UserinputService of the same name. Although it is possible to detect mouse button events on any GuiObject using GuiObject/InputBegan, only ImageButton and TextButton have dedicated events for these (e.g. TextButton/MouseButton1Down). This event ought not be used for general button activation since not all platforms use a mouse; see TextButton/Activated.
