I don't understand the modifications for these parameters yet..but here's a quote from the manual (which I don't understand either)
------------
8.7.2 PackLocation
Type:UIString
The PackLocation determines how a widget is re-positioned when it's parent changes size. The locations are represented as simple relationships between a widget edge, and a parent edge. The Child edge goes first, followed by the relationship, then finally the Parent edge. The two relationships are:
· Fixed - maintain a fixed number of pixels between the 2 edge
· Proportional - maintain the proportion between the edge distances and the parent widget size
The edges that may be referred to are:
· Near - Left for horizontal, Top for vertical
· Far - Right for horizontal, Bottom for vertical
· Center - The center point x value for horizontal, y value for vertical
Syntax example:
NFN,CPF
Horizontal: Child Near Edge - Fixed - Parent Near Edge
Vertical: Child Center - Proportional - Parent Far Edge
Horizontally, the near edge of the widget is kept a fixed distance from the near edge of the parent. Vertically, the center of the widget is kept a proportional distance from the far edge of the parent. Some combinations, obviously, are more useful than others.
8.7.3 PackSize
Type: UIString
PackSize indicates how the widget is re-sized when its parent changes size. The relationships are:
· Fixed - keep the size constant
· Proportional - keep the proportion between the widget's size and parent's size constant
· Absolute - keep the difference between the widget's size and parent's size constant
Syntax example:
A,F
Horizontal: Maintain a constant distance between Child and Parent Edges
Vertical: Keep the Child size constant
This example would work for stretching the menu on the map when it is resized to full screen.
Keep the widget a fixed size horizontally, but expand/contract vertically to maintain a fixed difference between the widget's height and parent's height.
----------------
In other words...it's all about how the resizing of the parent window affects it's sub-windows.
The manual for the UIBuilder is in the UIBuilder's root Directory btw
