The OVERLAYAREAITEM is a component within the OVERLAYAREA. The component opens up an area, in which a child component is added.

The x/y position is defined by attributes X and Y. You can define values in the following way:

1. by "pixel": "100" (of course a "pixel" is translated into some real position using the current scaling of the area)
2. by percentage: "50%"
3. by percentage minus pixel: "100%-20" (only minus is supported - no other operation can be used!)

The attribute BOUNDSANCHOR defines to which position of the OVERALYAREAITEM the x/y position is applied. By default it is "lefttop".

Example: if you want to apply content to the very bottom right, then you need to define: X="100%", Y="100%", BOUNDSANCHOR="rightbottom".
