Hi, Thank you for your response. The Ags*Meta widgets are really what I want. I think the screenreader can tell you what I am going to show you.
My idea is to implement a key stroke like Ctrl-M to show/hide these widgets and set focus. http://git.savannah.nongnu.org/cgit/gsequencer.git/diff/ags/X/editor/ags_notation_meta.h?h=3.1.x http://git.savannah.nongnu.org/cgit/gsequencer.git/diff/ags/X/editor/ags_automation_meta.h?h=3.1.x http://git.savannah.nongnu.org/cgit/gsequencer.git/diff/ags/X/editor/ags_wave_meta.h?h=3.1.x Well about positioning, I have some tool dialogs allowing you to do so. http://git.savannah.nongnu.org/cgit/gsequencer.git/tree/ags/X/editor/ags_position_notation_cursor_dialog.h?h=3.1.x http://git.savannah.nongnu.org/cgit/gsequencer.git/tree/ags/X/editor/ags_position_automation_cursor_dialog.h?h=3.1.x http://git.savannah.nongnu.org/cgit/gsequencer.git/tree/ags/X/editor/ags_position_wave_cursor_dialog.h?h=3.1.x So everything is just fine. best regards, Joël On Thu, Jan 23, 2020 at 10:05 AM apinheiro <apinhe...@igalia.com> wrote: > > > On 22/1/20 22:14, Joël Krähemann via gnome-accessibility-list wrote: > > Hi all, > > Hi, > > > > > > What about extending Atk interfaces to help assisting you to perform > > editing within 2 dimensional editing areas? > > > > I am the upstream author of: > > > > http://nongnu.org/gsequencer/ > > > > I have 3 editing areas: > > > > http://nongnu.org/gsequencer/api/2.3.2/libgsequencer/AgsNotationEdit.html > > http://nongnu.org/gsequencer/api/2.3.2/libgsequencer/AgsAutomationEdit.html > > http://nongnu.org/gsequencer/api/2.3.2/libgsequencer/AgsWaveEdit.html > > > > They have all a x-position in common.
