For the past few years we have got a lot of people asking us (the gedit team) why we did not provide a way to split a document and visualize it with several GtkTextViews. In this post I will point out the three problems that stop us from doing it.
- The cursor follows the insert mark from the TextBuffer.
- The selection is managed in relation to the insert mark and the selection-bound mark.
- The invisible tags are managed per document.
Why is this a problem?
- Well right now the invisible tags are not a big problem as we don’t support code folding yet, but probably we will do it soon, although in relation to the inser and the selection it is pointless to split a document and use it from several views if you are editing a document and both views are following the cursor no matter if you are in one view or another.
What would be the way to fix this?
- To manage the insert and selection-bound marks the GtkTextView should a per view-insert and view-selction-bound marks and follow only the ones set by it. The view should also modify the insert and selection-bound marks from the TextBuffer so this ones follow the ones from the view.
- In relation to the invisible tags, I am not totally sure how the best way would be for this. Probably doing something similar as with the marks.
With this post I just wanted to point out these problems in case somebody wants to fix them
