Previously that could cause a heap-use-after-free.
A reliable way to trigger it was to show the audio connection
dialog and connect a track's output to LTC master, then quit.
Popup Dialog Windows never unset the modal flag.
e.g. Session > Save Snapshot & switch.
Furthermore a 2nd dialog was able to get the menu stuck
forever (e.g. Snapshot & Switch .. -> Replace existing?
In order for the Filechooser Location widget to work two
things need to be setup, which only the FileChooserDialog
does:
* subscribe to Widget's "response-requested" signal
* call should_respond () hook from top-level window's
default handler.
The Location Entry emits "activates-default". In case of
the Dialog, that calls the dialogs response callback,
which then calls ` _gtk_file_chooser_embed_should_respond`.
That handles changes made by the user to the location entry.
-=-
Gtk::FileChooserWidget does not handle this, "response-requested"
signal is not exposed, nor is _gtk_file_chooser_embed_should_respond
available outside Gtk.
This change at least selects the file in the treeview, which
allows further handling, without interfering with FileChooserDialog's
behavior.

because the C++ API std::map:at can throw and exception
was not implemented (and also deemed excessive for the
case at hand). Also an explicit API for *p*plugin_pin
mapping is preferable and facilitates debugging.
When handling the `/set_surface` command, the code would set
plug_page_size to the new value first, and call `sel_plug_pagesize()`
later. The latter then sees the page size is already the same, so it
leaves it unchanged and also does not send the page size to the
OSCSelectObserver object. In practice, this means that only the default
plugin page size from the preferences or set with
`/set_surface/plugin_page_size` take effect and values set with
`/set_surface` are ignored.
Exactly the same thing happens for the send page size.
This code has been like this since it was first introduced in comit
9c0f6ea948 (OSC: Allow set_surface to set send and plugin page sizes.,
2017-06-13)
This commit fixes this by omitting the first assignment.
Before this commit, OSCSelectObserver would read the feedback value when
it was created, but then never update it anymore. In practice, the
OSCSelectObserver is created on startup, and when the surface connects
and configures feeback, this value is not applied.
For example, when sending `/set_surface` with a feedback value of
4 (Send SSID as path extension), `/strip/*` would get their ssid put
into the path, but `/select/plugin/*` messages would not have their
parameter id in the path. When setting the corresponding checkbox in the
default feedback preferences, it is applied as expected.
This commit passes the new feedback value to the OSCSelectObserver
instance whenever it changes, which ensures the value is applied as
expected.
