[Dr. Geo] [Bug 1699113] Re: The File Thumbnail Dialog focus

[hilaire]

Ugly hack:

DrGFileThumbnailDialog>>#handleFocusEvent: anEvent
    (anEvent isMouse and: [ anEvent isMouseWheel ])
        ifTrue: [ self activeHand releaseMouseFocus: self ].
    ^ super handleFocusEvent: anEvent

I guess, this will swallow the first scroll event, but all following are
handled by the scroll pane.

We should fix the openModal: method, to only change the mouse focus if
the active focus holder isn't nil.

Title:
  The File Thumbnail Dialog  focus

Status in Dr. Geo II:
  In Progress

Bug description:
  This dialog does not have anymore the focus when open by default.

  It is a problem when the user wants to browse with mouse wheel the
  sketch previews. Indeed he needs to first click on the dialog then he
  can browser with the mouse wheel.

  The user click should be unnecessary.
