Sizing and positioning a FFileSelector object.



Q. I have problems positioning and sizing a FileSelector and text edit
   object in the same GenInteraction. The file selector is not wide
   enough. It should be as wide as parent. 

   I tried HINT_EXPAND_WIDTH_TO_FIT_PARENT, but it did not help.

A. There are two parts to this problem. First, to expand the width of
   the file selector, use HINT_FILE_SELECTOR_FILE_LIST_WIDTH. This 
   will specify the width to make the file selector (in average
   character-widths). You will have to try different numbers to 
   see which looks best for your specific needs.

   The other problem is that the parent does not have the hints
   HINT_EXPAND_HEIGHT_TO_FIT_PARENT and HINT_EXPAND_WIDTH_TO_FIT_PARENT
   so it is not expanding to fit its parent. If you add those hints to
   the grouping interaction, it will also expand. 


Q. MyShowXBox position is unstable. I want to fix the position to
   middle and bottom of Interaction.

A. HINT_FULL_JUSTIFY_CHILDREN_VERTICALLY will take care of placing
   MyShowXBox at the bottom of SelectXGroup (the GenInteraction).

   You can add HINT_CENTER_CHILDREN_HORIZONTALLY to make MyShowXBox
   position to the middle (horizontally) of the GenInteraction.
