Analysis

Overview

The goal of this revision is to add more interactivity to stickies - text editing and dragging.

Task requirements

• The default background color should be yellow, semitransparent (red=100%, green=100%, blue=20%, alpha=75%).
• The text color of stickies should be non-transparent and:
  • Black - if the brightness (see below) of the background is more than 50%
  • White - otherwise (optional, if HotText allows it).
  • The brightness is the luma, the Y component of the color in YUV color space.

• Add Hot Text to stickies so they can be edited.
  • Only plain text editing functionality is required.
  • When removing a sticky, confirmation dialog should be displayed only for non-empty stickies.

• Create a halo button for moving stickies with the mouse.
  • Use the same button as the frame move button.
  • Place the button to the left of the remove button.
  • In later revisions a title bar like frame's future title bar will be needed.

• (optional) Create a halo button for changing sticky's background color. The alpha value should not be changed (75%).

• Reuse as much as possible of the code for the same functionality for frames.

Task result

Source code.

Implementation idea

• The halo button should be of type MoveHaloButton.
• Add it to StickyHaloMenu.

• In StickyRemoveButton change the condition to if (sticky.text().get().length() > 0).

How to demo

• Run Sophie and create a new book (if no book is available).
• Go to the Stickies palette.
• Create a new sticky.
• Type some text in it.
• Drag the move halo button to move the sticky.

Design

• Rename the classes SceneStickyView and SceneAudioAnnotationView to StickyView and AudioAnnotationView, respectively.

• Create a class org.sophie2.main.app.halos.pageelement.PageElementMoveHaloButton which extends MoveHaloButton.
  • method protected ImmRect translateRect(ImmRect bounds, int newX, int newY) that translates a rectangle.
  • pull up the property workArea (from FrameMoveHaloButton).
• Create a class StickyMoveHaloButton.
• FrameMoveHaloButton and StickyMoveHaloButton should extend PageElementMoveButton.
• Add StickyMoveHaloButton to StickyHaloMenu.

• In StickyRemoveButton change the condition to if (sticky.text().get().length() > 0).

• HotText: ...........

• Text color:
  • Create textColor auto property of type ImmColor in StickyView.
  • Return color according to the analysis requirements above.
  • Use the following formula for the brightness:
    • Y = 0.2126 R + 0.7152 G + 0.0722 B.
  • Apply that color to the sticky's title.
