Fixes: #11756
Context: Debian Bookworm only have GCC that links to MSVCRT C library.
Actually, crossroads is failing on our CI probably due to GCC-MSVCRT.
On Debian, there is GCC-UCRT too but it is marked as Experimental and
crossroad does not support it nor Clang-UCRT yet: GNOME/gimp!1860.
Some people reported crossroad working with GCC-MSVCRT in Fedora but
adding a brand new pipeline would be at least suboptimal to mantain.
So, we are temporarely moving from crossroad to quasi-msys2 project which
have UCRT support for both GCC and Clang (it takes compiler resources from
MSYS2). The compilers itself we will take from Debian Testing for parity
(they are standard GCC and Clang with proper CFLAGS set by quasi-msys2).
We may go back to Crossroad when it has UCRT support like quasi-msys2.
Instead of loading the GtkBuilder .ui file we now create all widgets in
code.
Added several support functions to reduce code copy/pasting and making
additional widgets and supporting more metadata easier.
The overall layout should still look the same, with a few exceptions:
- Each notebook page only uses one grid. This makes it possible to align
all data entry widgets.
- Featured Organization and it's code were two treeviews next to each
other. These are now organized below each other to make automatic code
generation easier.
- Since we needed to touch this code anyway, I also fixed Xmp.dc.creator
and Xmp.iptcExt.ModelAge to be multiline. This closes#7286.
- The old icons used for the date button, add, and remove row buttons
were replaced by gimp-grid, list-add and list-remove.
Since this was the last .ui file used in GIMP plug-ins, we remove all
files from the .ui subdirectory and references to that.
Note that there are several more places where GtkBuilder is used, but
those cases uses strings defined in code instead of .ui files.
Simplifies chooser widgets (e.g. GimpBrushSelect) by eliminating attributes (e.g. opacity) of chosen resource.
See #8745, but this commit fixes that by first refactoring the code.
Refactors GUI widgets (e.g. GimpBrushSelectButton and GimpBrushSelect etc.)
Refactor by "Extract class" GimpResourceSelectButton from GimpBrushSelectButton etc.
This moves common code into an inherited class (formerly called GimpSelectButton)
but the subclasses still exist.
The subclasses mainly just do drawing now.
Refactor by "Extract module" GimpResourceSelect from GimpBrushSelect etc.
Moves common code into one file, generic at runtime on type of GimpResource,
that is, the new code dispatches on type i.e. switch statements.
In the future, when core is changed some of that can be deleted.
The files gimpbrushselect.[c,h] etc. are deleted.
The module adapts the API from core to the API of callbacks to libgimp.
Note that core is running the resource chooser (select) widgets remotely.
Core is still calling back over the wire via PDB with more attributes
than necessary.
The new design gets the attributes from the resource themselves,
instead of receiving them from core callback.
The libgimp side adapts by discarding unneeded attributes.
In the future, core (running choosers for plugins) can be simplified also.
Fix gimp_prop_chooser_brush_new same as other resources.
Finish changes, and clean style.
Annotations
This is an extension containing a few demo plug-ins. This is good to
demonstrate the extension format. It will also allow to disable these
plug-ins (if at some point, one doesn't want to show these demo
plug-ins anymore).
And finally it deals with the fact that our plug-in code is stupid, as
it just tries to find the first executable with the same name (minus
extension) as the plug-in folder. This doesn't go well on Windows, where
the permission system is non-existent. So our code just ends up trying
to run the first file with a similar name in a plug-in folder. As the C
goat-exercise contains both an exe and the C source (and the system
probably returns files in alphabetic order), GIMP under Windows tries to
run the C source instead of the executable (this obviously doesn't go
well).
We could try to do more complex logics, like not aborting if the first
file run fails and try the next one in the plug-in folder. Or maybe just
rename the C file to another name. But any of these is just in the end
the proof that our plug-in discovery right now is just bogus. The
extension system is explicit, not based on randomly trying out files.
Plug-ins entry points are explicitly listed in the metadata manifest.
