Maplets Package Updates


The Maplets package has been updated several times since its release as an add-on package to Maple 7; in Maple 8, Maple 9, Maple 9.5, and, most recently, in Maple 10.

Updates in Maple 8


Changes to the Maplets package in Maple 8 include the following.

Get, Set, and SetOption Changes


The major change to the Maplets package is to the routines Get and Set and the element SetOption.  Previously, it was necessary to convert all values to strings such as "true", "false", or "#A332D3" which represents a violet color.  These routines now accept the same input as the original element.


For example, the following Maplet application has a button with a red background. Clicking the first button changes the background to blue.  Clicking the second button changes the background to green.


ToGreen := proc()
   print( Maplets:-Tools:-Get( 'B(background)' ) );
   Maplets:-Tools:-Set( 'B(background)' = 'green' );
end proc:

maplet := Maplet([
      'background' = 'red',
      SetOption('B(background)' = 'blue')
      Evaluate( function = 'ToGreen()' )



This affects setting options such as visible, enabled, and other boolean valued options, where strings ("true" and "false") should be converted to symbols ('true' and 'false').

Other Changes
