GtkFileChooser's API predates GIO by a few years, so it started off with
filenames and URI as character arrays. After introducing GIO as a
dependency, the API included GFile-based entry points.
It's much more appropriate to use GFile everywhere, as we want to
encourage people to use GIO instead of passing random bytes to low level
POSIX API.
See: #2455
The FileChooser ToolKit (fctk) had its own machinery to handle default
sizes which was completely busted and trying to marshal random numbers
through the widget hierarchy that maybe made sense in 2012 but don't do
now.
Get rid of it, just keep the dialog's GSetting - which funnily enough
used to be written by the dialog but written by the widget.
But that's fctk for you.
This reverts commit 2ed533c3e1.
This also made the filechooser dialog not save the window size anymore,
which does not depend on the gtk_window_get_position() removal.
I was a little overzealous when going
for the new default handling here. We
can't switch to gtk_widget_activate_default
before we actually handle the default.activate
action.
Instead, use the new way of activating default.
I think most of the default handling in
GtkFileChooserDialog should be dropped, but
for now this keeps things working.
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
We were only storing the dialog size on unmap, but resetting to the
stored default value more often, e.g. on focus-out. This was causing
the dialog to 'jump back' to its remembered size after the user
manually resized it, leading to frustration and bug reports.
Instead, save the dialog size on every ::size-allocate of the toplevel.
To avoid needlessly spamming dconf, only write the new value if it
changed.
When the dialog is as narrow as possible, we still want some
space between the entry and the search button, so use margins
around the entry and label instead of box spacing.
Make the file chooser entry optionally capture Escape
and emit a signal. Make the file chooser widget hide the
entry on that signal and go back to the path bar.
This gives us a two-level undo:
location entry -> path bar -> dialog close.
When the location entry is permanently displayed in the
header for save mode, we still let the first Escape close
the dialog.
The height of the text buttons depends on the font height,
whereas the search button has a fixed-size icon in it...
Prevent unevent heights by putting them all in a size group.

Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
