Andreas Kling	9b13a3905b	LibGUI: Support multiple GTextEditors editing the same GTextDocument ... With this patch, you can now assign the same GTextDocument to multiple GTextEditor widgets via GTextEditor::set_document(). The editors have independent cursors and selection, but all changes are shared, and immediately propagate to all editors. This is very unoptimized and will do lots of unnecessary invalidation, especially line re-wrapping and repainting over and over again.	2019-10-27 19:36:59 +01:00
Andreas Kling	f96c683543	LibGUI: Move visual line metadata from GTextDocument to GTextEditor ... This patch decouples GTextDocument and GTextDocumentLine from the line wrapping functionality of GTextEditor. This should basically make it possible to have multiple GTextEditors editing the same GTextDocument. Of course, that will require a bit more work since there's no paint invalidation yet.	2019-10-27 18:00:07 +01:00
Andreas Kling	f1c6193d6d	LibGUI: Move GTextDocument out of GTextEditor ... The idea here is to decouple the document from the editor widget so you could have multiple editors being views onto the same document. This doesn't work yet, since the document and editor are coupled in various ways still (including a per-line back-pointer to the editor.)	2019-10-27 16:44:16 +01:00
