GLib list
Some examples depend on GList that you removed in the lablgtk2on3 branch. I started to reimport from the master branch but it seems that in Gtk2 GList are used with GtkList. I don't know how worked Gtk2 and GtkList, I just know that Gtk3 uses GList like this:
GList *
gtk_container_get_children (GtkContainer *container);
Have you got any advices on this ?
drawing.ml example
The drawing.ml example fail with:
../src/lablgtk2 -localdir drawing.ml lablgtk/examples lablgtk2on3
File "./drawing.ml", line 18, characters 18-32:
Error: Unbound module GDraw
Hint: Did you mean Grab?
Furthermore it uses an GdkDraw api which is outdated (https://developer.gnome.org/gdk2/stable/gdk2-Drawing-Primitives.html#gdk-draw-point) in favor of Cairo. Does cairo work with lablgtk ?
Convert README to Markdown
Maybe it makes sense also to modernize the README look for the first lablgtk3 release?
Segfault when initializing class using window
I have a simple program which works with lablgtk2 but segfaults with lablgtk3. The program
class wrapper =
let window = GWindow.window ~title: "demo" ~show: false ()
in
object (_self)
inherit GObj.widget window#as_widget
method window = window
end
let _ =
let _locale = GMain.init () in
let wrapper = new wrapper in
ignore@@ wrapper#window#connect#destroy ~callback: GMain.quit;
wrapper#window#present ();
GMain.main ()And I compile it using
ocamlfind ocamlc -package lablgtk3 -linkpkg -thread -g -o demo demo.mlAnd when I run it segfaults wtih the following stack trace
systemd-coredump[60499]: Process 60497 (demo) of user 1000 dumped core.

fails to compile on ocaml 4.02.3
README says that one needs ocaml-3.11 or more (4.06 is preferred)
When compiling on a debian stable machine (ocaml 4.02.3):
ocamlc.opt -w s-3+52 -warn-error A-52 -c gutf8.ml
File "gutf8.ml", line 71, characters 26-27:
Error: The function applied to this argument has type int -> int -> string
This argument cannot be applied with label ~pos
Makefile:192: recipe for target 'gutf8.cmo' failed
For debian it would be fine to require ocaml >= 4.05, but then please say so and adapt the check in
configure.in accordingly.

Windows Dune Build
I am opening this issue to track:
- the windows build using Dune
- and how to add Travis support.
First question is what should the right windows environment be, we got some interesting comments here: https://discuss.ocaml.org/t/preferred-ocaml-windows-environments-mainly-for-continuous-integration/3299/3 but I am not sure I fully understand all the nuances here. See also ocaml/ocaml-ci-scripts#284
I tried to setup up Travis, however my knowledge of windows is too limited and the Travis windows environment is too bare-bones for me to know how to do it.
Regarding the Windows Dune build @MSoegtropIMC has commented:
I would say the issue is the option
"-Wl,-luuid"in\build\lablgtk-3.0.beta4\_build\default\src\clink-gtk+-3.0.sexp. I think the option should be either"-ldopt "-link \"-Wl,-s\""or just"-link -Wl,-s"so that flexlink forwards it to the system linker (see my comments in the lablgtk2 build in an old makecoq_mingw.sh). But the sexp file is auto generated on each build and I couldn't find out which magic leads to the effect that these options are in there. I searched the lablgtk and dune sources for uuid without success. So I don't know what to change in order to change these options.
Problem with GPack.layout adjustments
Here is the layout definition from gPack.ml
let layout ?hadjustment ?vadjustment ?layout_width ?layout_height =
Layout.make_params []
?hadjustment:(may_map GData.as_adjustment hadjustment)
?vadjustment:(may_map GData.as_adjustment hadjustment)
?width:layout_width ?height:layout_height ~cont:(
pack_container ~create:(fun p -> new layout (Layout.create p)))It looks wrong because the vadjustment parameter is never used, but hadjustment is used twice. I've tried to create a simple example to see what happens and something is wrong even if not exactly what I was expecting.
let main () =
let _local = GMain.init () in
let window = GWindow.window ~title: "Layout Demo" ~width: 450 ~height: 450 () in
ignore@@ window#misc#connect#destroy ~callback: GMain.quit;
let sw = GBin.scrolled_window ~packing: window#add () in
let layout = GPack.layout
~hadjustment: sw#hadjustment ~vadjustment: sw#vadjustment
~layout_width: 600 ~layout_height: 600
~packing: sw#add () in
let a = GMisc.label ~text: "A" () in
layout#put a#coerce ~x: 20 ~y: 20;
let b = GMisc.label ~text: "B" () in
layout#put b#coerce ~x: 500 ~y: 500;
window#show ();
GMain.main ()
let _ = main ()What happens when I compile and run this code is that the vertical scrolling works and horizontal scrolling doesn't.
However if I scroll horizontally and then vertically then it jumps to to the correct position.
Hope this helps
src/propcc.ml and src/propcc.ml4 are out of sync in lablgtk3 branch
Commit a0c89b2 did update src/propcc.ml with a new boxed type, but left src/propcc.ml4 untouched. This results in potential issue when using a fresh clone, as make might consider that src/propcc.ml needs to be regenerated from the obsolete src/propcc.ml4. This in turn leads later to a compilation error:
ocamlc.opt -w s-3+52 -warn-error A-52 -c gObj.ml
File "gObj.ml", line 224, characters 29-41:
Error: Unbound value Signals.draw
Small fix needed for OCaml 4.10 compat.
Which branch of git corresponds to lablgtk2? Anyway for OCaml 4.10 you will need a very small fix:
https://src.fedoraproject.org/rpms/ocaml-lablgtk/blob/master/f/lablgtk-2.18.8-ocaml410.patch
Why are properties of Widget (et alt.) not "wrap"ped?
Dear @garrigue or whoever knows,
I don't understand why the flag "wrap" is not set on some widgets in .props files, with the result that getter and setter for properties are not generated.
Example: class Widget in GtkBase has no wrap flag and all of its properties are unavailable.
In particular, the setter for the "events" property is not and it is necessary to make "drawing_area"s reactive
to button touches, in order to restore functionalities of no-longer-there widgets.
What is the expected way to restore those props? Write stubs by hand? Use "wrap" everywhere?
Thanks,
C.S.C.
Linking issues with gcc-10
I'm unable to compile labgtk3 3.1.0 since I've upgraded my gcc version, with ld reporting multiple definitions of ml_table_extension_events, declared in src/ml_gdk.h on line 89. The symptom looks similar as an issue reported against OCaml itself, and replacing CAMLexport by CAMLextern in the declaration (which technically, without the extern, is a "tentative definition"), as suggested there, indeed fixes the issue.
GTK3: status_icon#set_tooltip_text is missing
GTK replaced gtk_status_icon_set_tooltip with gtk_status_icon_set_tooltip_{text,markup}:
https://gitlab.gnome.org/GNOME/gtk/commit/d06e67023cf779f7af3e508de64ac1316ec08508
However, it appears that lablgtk simply deleted the method (in dc9aaad).
lablgtk3 beta6 build-depends on camlp4
Hi,
somewhere between beta3 and beta6 a build-dependency on camlp4 seems to have creeped in, or at least dune thinks so:
dune build
bash src/propcc.ml (exit 127)
(cd _build/default/src && /bin/bash -e -u -o pipefail -c 'camlp4o pr_o.cmo -impl propcc.ml4 -o propcc.ml')
/bin/bash: camlp4o: command not found
bash src/varcc.ml (exit 127)
(cd _build/default/src && /bin/bash -e -u -o pipefail -c 'camlp4o pr_o.cmo -impl varcc.ml4 -o varcc.ml')
/bin/bash: camlp4o: command not found
File "src/dune", line 11, characters 12-29:
11 | (libraries dune.configurator))
^^^^^^^^^^^^^^^^^
Error: Library "dune.configurator" not found.
Hint: try: dune external-lib-deps --missing @@default
This the release of lablgtk3 tagged 3.0.beta6.
-Ralf.
GTK3 branches cleanup
As it was indicated in the bug #34 it is not clear which one is "real" GTK 3 branch, so it makes sense to remove or rename irrelevant branches, something like "legacy_blabla" or "old_blabla".
move lablgtk2 examples into a subdirectory in the lablgtk3 branch
It is currently unclear which examples have been updated to gtk3. Moving everything into a gtk2/ subdirectory and then copying them back as they are updated would both make things easier to find, and be a valuable guide to updating code (since we could then diff foo.ml gtk2/foo.ml to see what changed between 2 and 3).
I'd be happy to do this if people think it's a good idea.
build-dependency on camlp5 should be documented in *.opam
Hi,
it seems that the build process requires camlp5 ("make build" fails when it is not installed), I guess this should be mentioned in the *.opam files.
-Ralf.
GTK+ 3 support
Seems there was a branch for that already https://github.com/garrigue/lablgtk/commits/gtk3.x
[lablgtk3 beta6] Install does not use stublibs/
I am packaging lablgtk3 for Arch Linux and running in a number of issues.
When using the ocamlfind-based build system, so-files are installed in usr/lib/ocaml/lablgtk3/ instead of usr/lib/ocaml/stublibs/. Besides, it overrides usr/lib/ocaml/ld.conf which looks like a really bad idea and is a no-go for packaging... (possibly related to #18 ?)
Here is an example of so-file installed in the wrong location:
-rwxr-xr-x root/root 376352 2019-11-01 14:19 usr/lib/ocaml/lablgtk3/dlllablgtk3.so
-rwxr-xr-x root/root 60648 2019-11-01 14:19 usr/lib/ocaml/lablgtk3/dlllablgtksourceview3.so
Here is the content of the overwritten ld.conf, which is completely wrong:
/build/lablgtk3/pkg/lablgtk3/usr/lib/ocaml/lablgtk3
Here is how I build lablgtk3:
./configure --prefix=/usr \
--without-gtkspell \
--with-gtksourceview3
make world
make opt
and then install with:
make DESTDIR="/build/lablgtk3/pkg/lablgtk3" install
When using the old-install target, the libs are installed in usr/lib/ocaml/stublibs/ as expected.
lablgtk does not to compile with ocaml trunk
While testing for ocaml/ocaml#1320 I stumble on an error for lablgtk, the commit used are in the log.

[build] gtkdoc support?
gtkdoc is an ocamldoc plugin that allows to link to GTK upstream documentation, with the move to Dune, ocamldoc is now deprecated in favor of odoc as a documentation generator and we have lost this functionality. There are two ways we could fix this:
- add an
ocamldocrule to the dune rules that generates old-style docs again - tweak odoc output so we add the links back.
I think both of them should be reasonably easy to do for someone motivated.

Linking failure on MacOS (darwin) and gtk+3-3.24.10
CoqIDE has been using lablgtk3 (3.0.beta6) since a few month. It used to build fine on MacOS with GTK 3 at version 3.24.9.
With version 3.24.10 of GTK3, there is the following linking error:
OCAMLOPT -o bin/coqide
Undefined symbols for architecture x86_64:

These missing functions belong to the GtkPlug and GtkSocket APIs which are supposedly only available on X11 platforms (as described there: https://developer.gnome.org/gtk3/stable/GtkPlug.html). So the error is somehow expected. What is strange is that it did not show up before.
NB: I get the same error when trying to build the “example3” test program (from https://github.com/garrigue/lablgtk/blob/lablgtk3/examples/sourceview/example3.ml).
Expose GDK_MODIFIER_INTENT_PRIMARY_ACCELERATOR
Hi,
I was wondering if it would be possible to expose access to GDK_MODIFIER_INTENT_PRIMARY_ACCELERATOR in lablgtk?
It would enable application developers to have native feeling shortcuts on mac where the default modifier is not control.
dune 2.7.0 says: Error: "dialog-thread" is an invalid module name.
+ dune build -j5
File "examples/dune", line 11, characters 3-16:
11 | dialog-thread drawing
^^^^^^^^^^^^^
Error: "dialog-thread" is an invalid module name.
Module names must be non-empty and composed only of the following characters:
'A'..'Z', 'a'..'z', '_', ''' or '0'..'9'.
Hint: dialog_thread would be a correct module name
Fix is to rename the example.
"make install" should create missing directories
"make install: should create missing directories (usr/lib etc.). This is important when using a nonempty value for DESTDIR since then one cannot assume any already existing directories. Packagers from software distributions use this to install into an empty staging directory.
For instance :
% DESTDIR=/home/treinen make install
make -C src install
make[1]: Entering directory '/home/treinen/projects/lablgtk/src'
mkdir -p "/home/treinen/usr/local/bin"
mkdir -p "/home/treinen/usr/local/lib/ocaml/4.05.0"
touch: cannot touch '/home/treinen/usr/lib/ocaml/ld.conf': No such file or directory
make[1]: *** [Makefile:382: findlib-install] Error 1
make[1]: Leaving directory '/home/treinen/projects/lablgtk/src'
make: *** [Makefile:5: install] Error 2
Here the problem is that /home/treinen/usr/lib does not exist (not the missing "local")
Automatic generation of lablgtk bindings
Hi everybody,
lablgtk bindings are (mostly) hand-written. The Haskell guys instead made a much better job, automatically generating their bindings from GI (GObject Introspection). I have assigned to a master student of mine the task of trying to adapt the Haskell code to spit-out "lablgtk"-like bindings.
The student worked extremely well and there is now a working prototype at:
https://github.com/illbexyz/ocaml-gi-gtk
The prototype is not fully completed: some ad-hoc Gtk types (eg. GArrays) still need some code. However it can already generate twice the number of methods of the current bindings and it should work on any GI library. I have tried a few examples and they work.
The student has now ended his master period and I need to decide if investing more resources on the project or not. Here I list some pros&cons of automatic generation:
PROS
- full coverage of Gtk libs and additional GI libs
- code better aligned to the C API (easier to understand the doc)
- "front-end" code, i.e. the code to parse the GI format, shared with the Haskell community and thus better maintained
CONS
- dependency on Haskell code; it could be removed by porting all the generation code to OCaml
- no more ad-hoc stuff: for example some methods now have labels, but not in a systematic way; a lot of other small changes here and there exist now to provide a more camlish API and they would disappear
- need to port (again) all existing code (Coq, etc.) to the new API. The student tried to stay as close as possible to current lablgtk, but some changes here and there must be applied (e.g. right now the mapping from widgets to files is arbitrary, e.g. some in GMisc, etc.)
What are your opinions?
Cheers,
C.S.C.

gBuilder.cm* no longer distributed in beta4
Hi,
gBuilder.ml* is no longer compiled in beta4. Therefore the code generated by lablgladecc does not
work either.
Sorry for not having check before, I was on mission and I am just back.
please clarify licence of examples/*
Hi,
most of the files under examples/ have a header "There is no specific licensing policy, but you may freely take inspiration from the code, and copy parts of it in your application." It is not clear what that means.
For instance, is one allowed to redistribute the code, or derived works of this code ? If yes, under
which licence?
If you wish that there are no copyright restrictions on the code then please state this clearly, or otherwise choose one of the existing permissive licences thar are around.

It appears that "make doc" still depends on camlp4
Howdy! The following lines seem to be in the Makefile, and they prevent a build on a machine without camlp4 installed.
gtkdoc.cmo : gtkdoc.ml
$(CAMLC) -I +ocamldoc -pp "$(CAMLP4O) pa_macro.cmo $(ODOC_DEF)" -c $<
leftover .cvsignore files
a minor issue : there are some leftover .cvsignore files, it would be nice if you could delete them:
$ find . -name .cvsignore
./doc/.cvsignore
./applications/browser/.cvsignore
./applications/unison/.cvsignore
./applications/camlirc/.cvsignore
./examples/text/.cvsignore
./examples/glade/.cvsignore
findlib lablgtk3-sourceview3 vs lablgtk3.sourceview
I'm on lablgtk3-beta6
When installing lablgtk3-sourceview3 via dune it is found by ocamlfind as lablgtk3-sourceview.
But when installing / building via the Makefile it will show up as lablgtk3.sourceview.
I suspect only the former can be sustained, so probably the Makefile based build should be either removed or adapted to install in the same way as dune does.
Gpack.paned does not implement Orientable
There doesn't seem to be any way to retrieve the orientation of a pane after creating it. (lablgtk3 branch)
Custom widget
Is it possible to create a custom widget using lablgtk3? If it is possible I beg for some hints, since reading the library code I'm unable to understand
Documenation for GWindow.window is not up to date
The documentation for GWindow.window in src/gWindow.mli#L142 is not up date.
There are parameters which are not longer present and actual parameters are missing. Here are what the correct values seems to be
(** @param kind default value is [`TOPLEVEL]
@param title default value is [""] (but the title of main window of program is set to program name)
@param decorated default value is [true]
@param deletable default value is [true]
@param icon default value is [false]
@param icon_name default value is [""]
@param modal default value is [false]
@param position default value is [`NONE]
@param resizable default value is [true]
@param screen default value is is [None] (most probably is set to [Gdk.Screen.defaualt ()] but I was unable to check it)
@param type_hint default value is [`NORMAL]
@param urgency default value is [false]
@param wmclass default value is [None] (deprecated since 3.22)
@param border_width default value is [0]
@param width default value is [0] (but set to [200] for an empty window)
@param height default value is [0] (but set to [200] for an empty window)
@param show default value is [false]
*)I've got most of those by creating an empty window and checking its properties.

[opam | macOS] lablgtk3 seems to need both libffi.6.dylib and libffi.7.dylib
Hi,
I was installing lablgtk3 for CoqIDE using opam on my Mac Book.
I got errors said some codes need libffi.7.dylib but others need libffi.6.dylib also.
I have both of libffi in homebrew. I switched libffi.7.dylib (libffi 3.3) into libffi.6.dylib (libffi 3.2.1)
but just ends up with error as I said above.
I also got the same error when I built from the source code.
Is this my environment's problem?
The following is a long error log:

Changes in dune >= 1.7.2 break reporting pkg-config errors in lablgtk3 beta5 on macosx
Hi, the semantics of query in Configurator.V1 changed in dune 1.7.2 (see ocaml/dune#1842). As a consequence, a query to query of the form gtk+-3.0 >= 3.18, as generated by Dune_config.gen_pkg is not anymore valid under macosx (package has >= in it and line let p = sprintf "%s/opt/%s/lib/pkgconfig" (quote_if_needed prefix) package of V1.ml produces an unexpected path). No query is thus sent to pkg-config.
On my installation, this had the effect of dune failing to report that libffi is not found by pkg-config.
So, querying pkg-config about gtk+-3.0 >= 3.18 as it is done in beta5 does not work with dune >= 1.7.2. Afaiu, this does not mean that installation will necessarily fail, but, that it would fail without reporting the cause if pkg-config and PKG_CONFIG_PATH are not configurated correctly enough.
I see two possible fixes: either requiring dune < 1.7.0 (since dune 1.7.0 and 1.7.1 are also to avoid), or requiring dune >= 1.8.0 (so as to also include ocaml/dune#1886) together with a modified dune_config.ml.
For instance, the attached patch seems to fix the problem by calling the query API of dune 1.8.0 as expected.
Towards an official release of lablgtk3 ?
(I'm not sure an issue is the right communication tool, but since GitHub provides no mailing lists...)
I have just released lablgtk3-3.0.beta7, which switches to a dune only build system, includes a variety of fixes, and uses a new layout for the source files.
If there is no major problem I suppose this could be a good timing to finally release an official 3.0.x.
Please report any new issue.

The README file should be updated for lablgtk3
Install issues on MacOS
I refer you directly to the issue on opam-repository where this has been discussed at length and you can find more information: ocaml/opam-repository#14718 (comment)
Various installation issues
Hi,
I tried to build the library and run the examples and got various compile errors.
First set could be solved by installing the following packages using the Linux package manager - in my case for Ubuntu, using apt:
sudo apt install libexpat1-dev libgtk2.0-dev
Second set could be solved by installing the following OCaml packages using opam:
opam install lablgtk
opam install cairo2
opam install camlp4 # fixing: camlp4o: command not found
Then I got the following issues:
dune_config src/cflag-gtkspell3-3.0.sexp,src/clink-gtkspell3-3.0.sexp (exit 1)
(cd _build/default/src && ./dune_config.exe -pkg gtkspell3-3.0 -version 3.0.4)
Warning: Package name "gtkspell3-3.0 >= 3.0.4" contains invalid characters. Use Pkg_config.query_expr to construct proper queries
configure error: gtkspell3-3.0 >= 3.0.4 not found.
dune_config src/cflag-gtksourceview-3.0.sexp,src/clink-gtksourceview-3.0.sexp (exit 1)
(cd _build/default/src && ./dune_config.exe -pkg gtksourceview-3.0 -version 3.18)
Warning: Package name "gtksourceview-3.0 >= 3.18" contains invalid characters. Use Pkg_config.query_expr to construct proper queries
configure error: gtksourceview-3.0 >= 3.18 not found.
What I did is probably just a workaround and it might be necessary to fix the package definition (I know next to nothing about dune...):
sudo apt install libgtkspell3-3-dev libgtksourceview-3.0-dev
Thanks for your efforts, Frank
