surfaceholder

obj_uiZ_surfaceholder
This is an object intended for advanced users.
It creates a surface(see game maker manual), and forces all children to be placed within that surface.
The code enabling this to happen is build into the uiz containment scripts, which should run every draw gui event using the code:

if uiz_cntn() then{

uiz_containend()
}

You can use this object to have an surface with objects on it and manipulate it in a way, may you desire that in your game.
The surface's size is equal to the object's width and height, and the surface will be resized inside a fix script such as uiz_fixgeneralpos();

Settings
-draw: Whether to draw the surface or not.
-clearsurface: Whether to clear the surface every begin draw event.

Readable variables
-surface: The surface id this objects holds.
