Spell Catcher X 10.3’s Developer Tools
Spell Catcher X 10.3’s DirectCorrect™ feature has some additional tools that developers might find useful when implementing/testing certain aspects of their text input (TSM or NSTextInput) and text-related accessibility support. I certainly did…
These tools are enabled by entering the following into the Terminal:
defaults write com.rainmaker.SpellCatcher SCSpellCatcherDeveloperMode -bool TRUE
You’ll need to Quit the Spell Catcher app first. If a Spell Catcher input mode is or has been active since you last logged in, you will need to Quit the Spell Catcher UI Server background app as well. Just use Activity Monitor to Quit it manually (no need to force quit).
And On With The Show
After enabling developer mode, the DirectCorrect inspector will contain some additional controls at the bottom of the window.
The function of most of the Developer controls should be pretty obvious to developers.
Draw word bounds
The basic bounding rectangle is drawn in blue, the ascent line in green, and the cyan "dots" are drawn as 4-pixel rectangles centered on
kEventParamTextInputReplyPoint for the first and last characters of the word.
More informative help tags
Get all positioning information
Select to always retrieve all available positioning information - TSM OffsetToPos, TSM Rects (Leopard only), and AX Bounds. This shows the maximum amount of positioning information in help tags for highlighted words.
Get all text attributes
Select to always retrieve all available font information - TSM DocAccess, AX Attributes, and RTF. This shows the maximum amount of attribute information in help tags for highlighted words.
Highlight every word
Totally Obsolete Cocoa Source Code
If you’d like your NSTextFields and textual NSTableColumns to draw just like the Finder and other Carbon apps do, squishing the text or truncating it in the middle, this is for you!
This implements a category method on NSCell that you can call from your NSTextFieldCell subclass’ -drawInteriorWithFrame override.
Download NSCell-Extensions.m, it's heavily commented.
