Overnight my brain had come up with the idea of investigating the Scintilla message API, so you saved me some work. Thanks heaps. > Scintilla message API ... see https://scintilla.org/ScintillaDoc.html @Colomban: it wasn't specially relevant, but I'm modding the "addons" plugin to add a few features from SlickEdit that I miss, one of which is deselecting after a copy. Thanks heaps to you too for the Scintilla message suggestion. Cheers, Austin. ___ Devel mailing list Devel@lists.geany.org https://lists.geany.org/cgi-bin/mailman/listinfo/devel

No, that makes sense now you say it, after all you have set the anchor, so when you (or the user) move the cursor, Scintilla considers between anchor and cursor to be the selection. Scintilla docs say: SCI_SETSEL(position anchor, position caret) This message sets both the anchor and the current position. If caret is negative, it means the end of the document. If anchor is negative, it means remove any selection (i.e. set the anchor to the same position as caret). The caret is scrolled into view after this operation. And you can send that using scintilla_send_message() which is in the API.

It only appears to have no selection -- as soon as I move the caret, it starts selecting again (even without the shift key!) So appears to have gone into a strange extend-selection-just-by-moving mode. I can make it return to normal by hitting ESC and then an arrow key, or by again setting the selection start and end points the to the same position. Weird or what?

I do hope so! :) Scintilla docs say "If the anchor and the current position are the same, there is no selected text." so probably set selection start and end both to current position. https://www.geany.org/manual/reference/sciwrappers_8h.html#a6649bca185bcc34837642cb61b4e7791 Cheers Lex > > Cheers, Austin. > ___ > Devel mailing list > Devel@lists.geany.org > https://lists.geany.org/cgi-bin/mailman/listinfo/devel ___ Devel mailing list Devel@lists.geany.org https://lists.geany.org/cgi-bin/mailman/listinfo/devel
