Analysis

Overview

There are different anchoring modes defining the way a frame should move according to the frame it is anchored to: In this revision of the task only character mode anchor will be implemented. Since drag n drop is not ready yet, the anchor hud will be used for defining where to anchor the frame. The goal of this revision is to implement anchoring support and demonstrate it's working.

Task requirements

• Create anchor halo. It should be draggable and clickable halo.
• Create anchor HUD with two dropdowns - Frame (frame list) and position (numbers) (like in trigger HUD). When the anchor is implemented, position dropdown won't be needed and will be removed.
  • Frame defines to which frame will this be anchored and position - to which position of the text.
• When a frame is attached to a position, when position is moved the frame is moved with the same offset as the position. This means that if the character is moved with 10 px right and down, the frame will be moved too.
• The frame can be moved by the user
• A frame cannot be attached to itself.

Task result

The result of this task is source code.

Implementation idea

Create an interface named Attachment.

How to demo

• Create a book, insert text frame, type in some text
• Insert second frame, click anchor halo, select the first frame from the dropdown and position 3 for example
• Move cursor in position 1 and type in some more text.

Design

In order to provide the anchoring prototype the following changes are made:

• added new enum AnchorMode - holds all modes of the anchoring.
• added new class Attachment with two attributes: first of type ResourceRef in order to hold the reference of the resource being attached and the second - the anchoring mode of type AnchorMode.
• In ImmHotText class add attribute of type Map<Attachment,HotInterval> - it holds map of all the attachments in the text.
• In HotTextBookResource class add property of type RwListProp<Resource> to hold all the anchored resources.
• Added new class Anchor which extends BaseProObject and implements Element - the element anchor. It has property of type Attachment - it holds the attachment that this anchor refers to, it's parent is of type Frame.
• Added new class AnchorView - it's parent is of type SwingTextView(only temporary) and has a property getRelPos - the rel pos of the character that this resource is attached to.
• In HotTextView class add new property List<Anchor> - holds all the anchors of the view.

• Add 4 classes for the hud (checked work).
• The logic should be the following : when the hud is closed : 1:in ImmHotText -> Map a new Entry is added, 2: in the HotTextBookResource is added the real resource , 3: the resource is deleted from it's old holder(will it be the same?)
