Analysis

Overview

The inplace editor provides functionality for editing text into the frame where the same text is laid out. Currently editing functionality is present, but the cursor position can be changed only with left and right arrows.

Task requirements

• The cursor position should be changeable by mouse click on text area.
  • When the user has clicked in the text, the cursor is placed there.
  • When the user has clicked in the text area, but not in the text, the cursor is placed as near as possible to the position where there is text.
• The cursor position should be changeable by up/down arrows.
  • When the position has characters before/after it on the previous/next row, the cursor goes there
  • When there is no such position, the cursor goes to the first/last character of the row.
  • When there is no such row, the cursor does not change it's position.
