[Alphacocoa-devel] [alphacocoa:tickets] #229 Selected text is invisible, depending on highlighting settings in System Preferences

[Bernard D. <bde...@us...>]

I have  implemented the following feature: Alpha now supports coloring of the background of the text area of document windows when the user selects Dark Mode at the system's level. There is a new preference called *Allow Dark Mode Text'*to control this feature. If it is set, the background is painted with a 75% gray and, in that case, the `Graphite` theme works as expected.
The background color for dark mode can  be customized using a new *Dark Background Color* preference.
These preferences are silently ignored if Alpha runs on a version of OS X older than 10.14.
All this will be in the next release of Alpha (9.1.2).

Changes committed to the repository ([rev. 1882](https://sourceforge.net/p/alphacocoa/code/1882/)). The core must be rebuilt.

If the Highlight colour, set in System Preferences →  General, is `Graphite` then the highlighting Alpha uses when text is selected is white, the text is white and they are invisible on the default white background. Selecting text effectively makes it invisible in the GUI. Chosing `Blue` as the highlight colour works around this bug. Possibly relevant: Dark mode is active. Reproduced on two different machines running different versions of macOS.
