How do I...Set the SaveAs Command to a Button

[Fiona|Dyalog]

In APL:

      ⎕USING←'' 'System.Windows,WPF/PresentationFramework.DLL'
      ⎕USING,←⊂'System.Windows.Controls'
         btn←⎕NEW Button
         btn #.WPF.SetCommand'ApplicationCommands.SaveAs'

In XAML:

Code: Select all

xmlns:apl="clr-namespace:MJHSoftware;assembly=MJHSoftware.APLExtension"
<Button Command="{apl:Command SaveAs}" />

where the call back functions are:

      ∇ CanExecuteMyCmd(sender args)
   [1] :Signature CanExecuteMyCmd Object,CanExecuteRoutedEventArgs
   [2] args.CanExecute←condition
      ∇

      ∇ ExecutedMyCommand(sender args)
   [1] :Signature ExecutedMyCommand Object,ExecutedRoutedEventArgs
   [2]
   [3] … code
   [4]
      ∇
