Change GimpFileDialog's file-procs properties to enum
GimpFileProcedureGroup and get them via the newly added API. Set
properties common to all dialogs in the parent class.
By default, it only saves the current file filter, but it allows a child
to implement its own state. It has been implemented by GimpSaveDialog to
save the preferred compatibility mode as well.
The code refactoring allows better readability which will allow in turn
to add more complex specific features making good use of the save/export
split concept.
- add gimp_image_get,get_xcf_compat_mode()
- add a compat toggle to GimpFileDialog which is shown and sensitive
only for a save (not export), and if the image structure allows
to save an old version at all. The button also has a tooltip
which explains why it is sensitive and what it does
- add "gboolean xcf_compat" to file_save_dialog_save_image()
- in file_save_dialog_save_image(), call image_set_xcf_compat_mode(TRUE)
only around the call to file_save() and set it to FALSE after saving
- in xcf_save_invoker(), honor the image's XCF compat flag and save an
RLE-compressed XCF if possible
The above is very convoluted and doesn't pass the "xcf_compat" boolean
directly because we can't change the parameters of gimp-xcf-save, and
because the gimp-xcf-save might be called indirectly.
- change start() and set_text() to use "format" and "..." instead of
"message", allowing to format progress messages in place
- s/cancelable/cancellable/
- move "cancellable" to be the second argument of start()
Current implementation had 2 issues, fixed by this commit:
1/ after the file save dialog is closed, the image would not close.
2/ if you switched the visible tab before saving the new image, it
would save and close the visible tab, instead of the expected one.
Fix default export extension to be as specified:
1. last export of this image
2. imported extension
3. last export of any image
4. png
2 and 3 were reversed in the code.
In order the fix the obvious confusion, add another file filter which
contains all the types that are savable with the dialog, name it
either "All XCF images" or "All export images", and make it the
default filter.
when dealing with native window handles. Also get rid of using
GdkNativeWindow and simply consistently use guint32 all over the
place. This is more obvious and consistent and keeps the diff to the
gtk3-port branch smaller.
Update export filename priorities according to changes in spec. Also
consistently use GIMP_FILE_EXPORT_URI_KEY instead of
GIMP_FILE_EXPORT_TO_URI_KEY. They have the same value.
Even though a user can only save to XCF in File->Save, the "All
images" filter shall show all images to allow a user to steal names
from non-XCF images and vice versa for File->Export, so make that
happen.
