background-drop-zome – Create 15px invisible drop zone for background

[deyan]

Create a 15 px invisible zone inside pages and frames (next to border). When image is dropped there, it should be set as background

[deni]

• If the padding is more that 15px, it will be included in the padding drop zone, too.
• For consistency, the main resource of a frame will be changed if a resource is dropped over a frame view but outside the background drop zone.

[deni]

• FrameView changes:
  • public static final int BACKGROUND_DROP_ZONE_WIDTH = 15;
  • public ImmRect getBackgroundDropZoneInnerRect() - gets the inner contour of the background drop zone of the frame view (in frame coordinates).

• Make FrameView.ON_PRE_IMPORT_IMAGE_FOR_BACKGROUND and ResourceImportLogic.ON_PRE_IMPORT_RESOURCE_OVER_FRAME_CONTENT respect this zone.

• RootPageView changes:
  • public static final int BACKGROUND_DROP_ZONE_WIDTH = 15;
  • public ImmRect getBackgroundDropZoneInnerRect() - inner contour of the background drop zone of this page view

• Add a new operation in ScenePageView - ON_PRE_IMPORT_IMAGE_FOR_BACKGROUND that handles pre-importing images over the background drop zone of a page. For now, it handles events only if {@link ResourceRefData} is transferred.
  • It can use the same DropHandler that is used for frames.

• The getBackgroundDropZoneInnerRect()s in FrameView and RootPageView cannot be moved in ElementView for two reasons:
  • Not all elements have background and it will be inappropriate for a view of an element without background to have a background drop zone.
  • The implementations are different - FrameView should respect the frame size and the padding while RootPageView should use the page size obtained from the book.

• Done according to the design together with the tickets for DnD visual indication.
• Source code: [8690] and [8697]

[meddle]

• The hierarchy of the DropHandlers is changed.
  • BaseDropHandler is renamed to ResourceDropHandler.
  • There is extender to ResourceDropHandler -> ElementDropHandler which all the ElementDropHandler extend.
  • The hadleExit method of ResourceDropHandler does nothing.
  • The hadleExit method of the ElementDropHandler sets the indication to be invisible.

And the analysis score/review???

3.5p
