For lists smaller than or equal to 7, use button-only dialog but still support keyboard filtering.

Note that people tend to choose between #(yes no) and hence we do need such a button-only version of a list chooser. Still, better than using menus in terms of input modality and visual consistency.

=============== Diff against ToolBuilder-Morphic-mt.175 ===============

Item was changed:
  ----- Method: MorphicUIManager>>chooseFrom:lines:title: (in category 'ui requests') -----
  chooseFrom: aList lines: linesArray title: aString
  "Choose an item from the given list. Answer the index of the selected item."
 
  aList size <= 7 ifTrue: [
  | dialog |
  dialog := DialogWindow new
  title: 'Please Choose';
  message: aString;
+ filterEnabled: true;
  yourself.
  aList doWithIndex: [:ea :index |
  dialog createButton: ea value: index].
  dialog selectedButtonIndex: 1.
  ^ dialog getUserResponseAtHand ifNil: [0]].
 
  ^ ListChooser chooseFrom: aList title: aString!

Here is some explanation:


You can filter all these dialogs by just typing something and then pressing <return> or <enter> or double-clicking some element in the list.

UIManager default chooseFrom: (Smalltalk classNames first: 7).
UIManager default chooseFrom: (Smalltalk classNames first: 8).
UIManager default chooseFrom: (Smalltalk classNames).

We need this button-only dialog because there is much code doing this:

UIManager default chooseFrom: #(yes no cancel).



Instead of asking for a confirmation dialog. I hope this works for everybody. I terms of modality and visual consistency, I am strongly against (mis)using pop-up menus for this choosing task in the future.

Best,
Marcel
