In this library text instances announce any change which happens with it. Due to this behavior Twisty provides cursors and layout objects which state are automatically restored after text changes.

Different behavior should be implemented by specific class of text tool (subclasses of TwyTextTool). It can be editor tool, selection tool, cursor tool, undo/redo tool and others. Text morph contains collection of such tools. Different combination of tools supplies different behavior. For example, text morph without any tools is simple readonly text field. Text morph with selection tool allows select text region and copy it to clipboard.

Text decorator decides how characters should be inserted or removed, how selected text region should be changed.

Re: [Pharo-dev] [ANN] Twisty, text with active state framework

by Nicolai Hess

Impressive! How does it compare to Rubric or TxText ? I see some similarities with TxText (and you worked on TxText too?). Does it mean this is a more complete version of TxText. With similar core and/or the same design. All classes are commented +1 for Twy -1 for Rubric :) What I like about rubrics textcomponents are the Text/Line decorations like in RubLipsumWithSegmentsExample (see screenshot). Does Twy support this too? 2015-11-26 11:07 GMT+01:00 Denis Kudriashov <dionisiydk(a)gmail.com>: > Iâm glad to announce new text framework Twisty. > > Twisty is text implementation based on active state idea.

Autoscrolling (in FastTable)

by Stephan Eggermont

Today we've had a design discussion on slack on autoscrolling with Morphic. The idea is to start scrolling up or down when drag-holding over a table. A similar approach should hold for scrolling panes. It started with me describing a working but not so nice approach starting stepping on #mouseEnterDragging:, checking the global hand position and button state in each #step:, stopping the stepping on #mouseLeaveDragging: or #mouseUp:. Thierry noticed the #newMouseFocus: taking of FastTable on #mouseEnterDragging: causes problems when dragging from one table to itself without leaving the table bounds. Henrik then wrote the code for FastTable, removing the mouse focus taking by adapting #handleMouseMove: The first results are in the latest version of FastTable on estebanlm/FastTable. The top and bottom parts of the table will now start scrolling the table rows when drag-holding over them. Further possible improvements: - expand/contract tree triangles when holding over them, taking priority over the start of autoscrolling; - adapt scrolling speed depending on distance from border - check starting delay, repeat rate and smoothness of the scrolling Stephan
