SpNumberInputFieldPresenter issue with panned layout and ProportionalLayout

[akevalion]

Hello there,

This issue involves SpPanedLayout, SpNumberInputFieldPresenter and ProportionalLayout

Steps

• run this code

  presenter := SpPresenter new.
  presenter layout: (SpPanedLayout newLeftToRight
  positionOfSlider: 280;
  add: (SpBoxLayout newVertical
      add: 'Label' expand: false;
      add: (SpBoxLayout newVertical
          add: SpNumberInputFieldPresenter new expand: false;
          yourself);
      yourself);
  add: SpButtonPresenter new;
  yourself).
  presenter open

• you will get this window

  

• change the slider position to the right

  

• then move it to the left

  

• can you see the error? yes we loose the arrows of SpNumberInputFieldPresenter.

To fix this

change the method ProportionalLayout >> #minExtentOf:in:, return 0@0 or remove the method then try again.

• move it to the right

  

• move it to the left

  

As you can see now the arrows are in the correct position. Although I do know the impact of this change, probably we will need a better solution.
