name of open file doesn't show in title bar when wrapped in qt

[hannesdelbeke]

would be great to show name of open scene in blender title bar

[hannesdelbeke]

bpy.data.filepath contains the filename

show path if file open

show star if file dirty

show Blender if new file/ no file path

>>> bpy.data.filepath
'C:\\Users\\user\\Downloads\\testcase.blend'

[hannesdelbeke]

we either need to subscribe to a hook in Blender, or create a listener.

msgbus

msgbus might let us subscribe to changes in filepath or dirty state.

app handlers

app handlers might also be an option

• bpy.app.handlers.load_post on loading a new blend file (after)
  (but does this trigger when we save a new blend?)
• bpy.app.handlers.save_post: on saving a blend file.

might also need

• bpy.app.handlers.persistent: to maintain the handlers between sessions, just like we use for the bqt operator

it seems app handlers can handle file path but not dirty state of the blend session

current workaround: disable qt wrapping with BQT_DISABLE_WRAP set to 1

blender 4 slightly changed it. showing unsaved for new scene
