living and learning (tabmenu template script inside!)

Ken, tabview scripters...

Here's the actual XOS template which I use anyday and copypaste anywhere for
tabmenus (or index fields).

It's simplified but has combined examples to show you how much advantage you
can take of a tab menu (or an option/pulldown menu). This thing has a
thousand uses!

local oldtab -- if this control is a menu then you want to remember which
view was last. You can also use a custom property or check that all view
groups are hidden in a loop which I'll skip writing for space off-topic
purposes - it was also shown in a recent mail quite elegantly...)

Imagine a tabmenu button with this script...

on menupick newtab, oldtab
  lock screen
  if there is a group/card oldtab then
    hide group/save card oldtab
  else if there is a fld oldtabthen
    ...
  end if

  if there is a grp/cd newtab then
    show grp/go cd newtab
  else
   propose a new one !!! (smart apps do this dont they ;)
  end if

  -- custom object routines go here
end menupick

The ifs check top to bottom the card or group hierarchies - if no group,
then maybe a field or graphic or card... This way the script can be used
without modification anywhere. 

I usually populate my menus before the choices or gui/views are designed in
the applications. With the option to create new cards or fields, for
example, this makes the design process automatic, when you choose it, it's
created if it didn't already exist!

If the tabmenu gets too long, consider using a side index field or a
pulldown menu instead. Tabs should be used for few items as possible (takes
longuer to read) but they are very practical to find something between 2 and
6 items across. 

That's the first metacard trick I wrote! It's not just a template to help
write software faster (given), it's a phylosophy to help software write
itself! 

(you can see many variations of this scripts in action in any of my stacks
at Monsieurx.com - the discrete browser has it a gogo! The options tabmen
has the index implementation. 

To make tabviews in tabviews, the tabview button and all it's scripts should
be grouped together (with the tabview at the lowest layer). Then you can
paste that group into another group with a tabview below. Watch the naming
of the groups if you have many. Conflicts in naming can hide a group in a
hidden group and it seems your software doesn't run logically anymore!

;))

Hey, thanks Ken for bringing this 
opportunity to write a thought of XOS!

as good as seeing things the app way...
