Analysis

Overview

Text select -

• Text selection is done by
  • clicking and dragging on text
  • double clicking on a word (selects the whole word)
  • shift + left (right) arrow select text in desired position (one character). On up/down the text is selected to the same position on the previous/next line if there is text on it or to the end of the line otherwise
• Should highlight text (with inversed colors)
• Should apply style to selection only. If nothing is selected, should apply styles from cursor position to the next non-existing character.
• Text selection should be draggable
• Multi select - multi select is done by selecting another part of the text with pressed ctrl key.
• Cursor position is local for non-chained frames. Selection should be kept for each different frame (cursor position - too)
• Text select in Preview mode, Presentation mode and Reader app
  • Cursor position is kept, but the carriage is not shown. This allows selecting text by shift+arrow, the behavior is the same as in the author app
  • Note that arrows without shift should only scroll and not change the carriage (cursor position)

Task requirements

• Add select support for text frames
• Clicking on a position with mouse sets the carriage to this position. Position is saved.
• Double clicking on a word selects the whole word
• shift + left (right) arrow select text in desired position (one character).
• Should highlight text (with inversed colors)
• Should apply style to selection only. If nothing is selected, should apply styles from cursor position to the following non-existing character.
• Multi select - multi select is done by selecting another part of the text with pressed ctrl key. (optional - if we have time)

Task result

The result should be code

Implementation idea

Selection is local for a frame, so add two new properties in the text frame class - one for the select caret and one for selection list (which hot units are selected). Also add interaction logic for handling selection operations
