Re: [platform-swt-dev] API for setting the selection color of a Text fie

[Eric Williams <ericwill@xxxxxxxxxx>]

Hi Lars/Thomas,

The selection color of Text widgets is set when setBackground() is 
called. The selection background color is always COLOR_LIST_SELECTION 
and the foreground is always COLOR_LIST_SELECTION_TEXT.

Note that Text (GtkTextView on the native GTK side of things) uses the 
same color constants as Table/Tree/List (GtkTreeView on GTK). This is by 
design as per GTK theming.

AFAIK there is no API to set the selection color of a Text widget. As 
Thomas pointed out, this only exists (to my knowledge) for StyledText.

As for your screenshot, I can't say for sure what is happening because I 
do not know the Cocoa color constants. But from a quick glance it looks 
like the COLOR_LIST_SELECTION value is clashing with whatever foreground 
color is in use (looks to be white or light gray).
