Re: [gedit-list] Is there a signal for text selection?

[steve love <stevelove gmail com>]

Thanks again, Paolo and Jesse. I've now got a first attempt at a plugin up and working.

I spent a lot of time programming with Notepad++ and one of the features I liked about it is that if you select a word, all occurrences of that word will be instantly highlighted within the document. It's similar to the way the Ctrl+K functionality works in Gedit, but it's triggered by text selection instead.

There's still an issue that I'd like to work out if anyone has any input. The plugin only works on double-click. If you try to select a word using the mouse or Shift+Arrows, it will only highlight the first letter or two. I'm using "notify::has-selection" as suggested. Is there something that signals that the selection is changing? For instance, if you're dragging the mouse to select a word? I couldn't seem to find anything like this in the documentation.

Actually it is GtkTextBuffer. In this case the inheritance goes like
this:

GeditDocument inherits from GtkSourceBuffer which inherits from
GtkTextBuffer.
