MILESTONE: gtk3 replaces gtk2 as default linux backend [message #52902]

I have reached an important milestone, commiting gtk3 branch (which I have been developing for the last couple of month) into U++ trunk.

This replaces gtk2 as our backend (BTW, small explanation here for future references: U++ is still 'emulated' GUI, with its own set of widgets; we are using gtk just as interface to host system, basically only top-level windows and events. The reason for using gtk3 as backend is mostly for improved integration).

With this backend I have also taken slightly different path for chameleon - we are now using only several basic 'looks' from gtk3 (namely shape of basic buttons, check/option boxes, menu looks, scrollbars, standard font and GUI colors) and generate rest (e.g. comboboxes) as "synthetic" GUI based on these. That should fix many small visual glitches that have plagued U++ in the past, especially with some exotic theming. Plus, unlike gtk2, gtk3 has support for UHD mode, so looks much better on my LCD Smile

Smile

Minimal version required for gtk3 is 3.8 - that accidentally coincides in historic timeline with C++11 support availability; for now however at least 3.22 (~2017) is required for full chameleon support. I also plan to develop some nice new default clean theme to replace that old XP look which was our fallback look for more than 10 years... that will probably be the theme for pre-3.22 gtk3 and definitely for plain X11.

It will take a month or two to mature this, please test & report problems...

Hello Mirek,

This is great news, thank you!

I'll have the chance to start testing the new backend -mainly with terminal ctrl- extensively, from the next week on.
I'll report any problems I encounter.

Best regards,
Oblivion.

Hi!

Thanks Mirek! This was great progress!

In order to make it compile the libgtk-3-dev needs to be installed. As a consequence, the build requirements on page https://www.ultimatepp.org/www$uppweb$uppx11$en-us.html need to be updated accordingly, e.g.:

sudo apt-get install libgtk-3-dev

Best regards,

Tom

I briefly tested examples/AddressBook application (based on 13848 svn revision) for GTK 3.22.30 on FreeBSD 10.4 and Fluxbox 1.3.7 window manager. Default Adwaita theme.

Contents of "~/.config/gtk-3.0/settings.ini" file:

[Settings]
gtk-font-name=Tahoma 10
gtk-button-images=1
gtk-menu-images=1

Looks like, there are issues with vertical scrollbar for ArrayCtrl, which is somehow blurred.

The Option widget on Search tab looks different (probably doesn't have background image), especially for disabled item.

https://i.postimg.cc/HV9C9D0v/Address-Book-search-tab.png

The "File" item in menubar have different colors and possible issues after mouse hovering on it, compared to other GTK 3 applications.

Hi,

IDE build:
- Ubuntu 18.04
- clang (clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final))

There is a problem with the StaticText and the Option in the Layout edit. Text is not displayed. But it is correct when the application is executed. See attached screenshot.

Hopefully fixed.

Also scrollbars should be nicer in more themes.

Hi,

Scrollbars are better. But StaticText and Option still have the same problem. Text is not displayed in the Layout editor. I also found that Label and LabelBox have the same problem.

Sorry, forgot to commit. Should be fine now, rev 13681.

Scrollbars are better. But StaticText and Option still have the same problem. Text is not displayed in the Layout editor. I also found that Label and LabelBox have the same problem.

Sorry, forgot to commit. Should be fine now, rev 13681.

Hello Mirek,

While compiling new version I see a lot of warnings that should be eliminated:

Well, most important warnings of those are about gtk3 more or less dropping support for multithreading - if remember some history of U++, we were at phase where the only thread eligible to do GUI was the main thread, then we went to some limited possibility to do things from other threads. If other thread was to do something in GUI, you had to PostCallback.

Interestingly, gtk just went in the exactly opposite direction - doing some GUI stuff from other threads is now deprecated and dropped in gtk4 and the recommend approach is to use their's PostCallback equivalent.

Now I have some ideas how to deal with it, but it will take some time.

(Plus of course there are some easier warnings to fixe, 'todo').

Quote:

Can you post tooltip screenshot? If not, can you describe colors?

Scrollbars I can fix. Would be nice to know which engine is that though...

Hello.
I briefly tested examples/AddressBook application (based on 13848 svn revision) for GTK 3.22.30 on FreeBSD 10.4 and Fluxbox 1.3.7 window manager. Default Adwaita theme.

I believe that with possible exception of scrollbars width, these should be now fixed.

Can you retry now? I have removed dependency on gtkglext, which we are not using anyway.

If it still does not work, do non-GL examples work for you?

Hi

For linux and BSD, gtk-2.0 is still in umk config (on U++ debian server).

Example: Makefile.in and uMakefile.in files from last snapshot contain "/usr/include/gtk-2.0" and more gtk-2.0 references.

While fixing warnings, I have encountered a little problem: It looks like whole trayicon API was deprecated in gtk3, they simply consider the whole thing "not modern".

What should I do here? Remove TrayIcon from U++/gtk3? Ignore warnings? Or perhaps provide X11 based code?

This sounds like lot of fun.

I guess dropping support for status icons in Gtk is legitimate option, as that's how the Gnome authors envision it and how they want it.

But as a KDE user, I would prefer if there were still APIs and tools in U++ to handle status icons normally.

But U++ is GTK3 based now, so ... I don't know. Maybe the X11 without GTK branch only to keep them supported and GTK3 branch to ignore any U++ API calls?

Seems quite awkward situation to me, I definitely like existence of status icons in the task bar in my desktop environment, and if some app is overusing it, I can uninstall the particular app. But I don't understand Gnome design decisions for many years, so this is just another one, I simply think completely differently about my computer "desk".

No worries, I have kept it with warnings disabled. Perhaps in future, if they decide to drop it, I can switch to X11 implementation, which is possible even with gtk3 backend. For now, problem solved.

(And yes, it is idiotic decision on gtk3 part. If they present it as multi-platform toolkit, they should care about more than Gnome).

Hello Mirek,

Apps that are compiled now and TheIDE itself have unusual (swapped) location of buttons OK and Cancel in standard dialogs.

I have three issues to report.

1. First, there are still references to gtk-2.0 in several files in svn.
The easier way to find them: 'grep -R --exclude-dir=.svn gtk-2.0 .'

2. Secondly, there is a typo in trunk/uppsrc/CtrlCore/CtrlCore.upp. xdmpc should be xdmcp I guess

3. Thirdly, I would like to understand this new strategy:

Extract of trunk/uppsrc/CtrlCore/CtrlCore.upp:

pkg_config(LINUX | FREEBSD) "freetype2 x11 xinerama xrender xft xdmpc fontconfig xcb xext";

pkg_config((LINUX | FREEBSD) !X11) "gtk+-3.0 libnotify";

So now U++ can be compiled with GTK dependencies only (GTK+libnotify) or GTK+X11 dependencies and we need pkg-config to compile CtrlCore?
"xinerama xrender xft xdmcp fontconfig xcb xext" are now mandatory for GTK+X11?

I need to understand this because current domake script is broken as:

* umk on debian server doesn't use '((INCLUDES))' anymore in ~/.upp/theide/GCCMK.bm
* exported Makefiles use pkg-config when using CtrlCore because of trunk/uppsrc/CtrlCore/CtrlCore.upp recent changes
* U++ won't compile if pkg-config is not there because of missing default includes
* Previously we only needed gtk3 x11 and libnotify

Extract of Makefile.in in new tarball snapshots:

CINC   = -I./ `pkg-config --cflags freetype2` `pkg-config --cflags x11` `pkg-config --cflags fontconfig` `pkg-config --cflags xcb` `pkg-config --cflags expat` `pkg-config --cflags libpng` `pkg-config --cflags xinerama` `pkg-config --cflags xrender` `pkg-config --cflags xft` `pkg-config --cflags xdmpc` `pkg-config --cflags xext` `pkg-config --cflags gtk+-3.0` `pkg-config --cflags libnotify`

I will fix 1 and 2 ASAP.

3: It is work in progress, however the idea is to depend on pkg-config, with basically empty INCLUDE/LIB paths. Do you know about any system that supports gtk-3 or C++11 and does not have pkg-config?

All POSIX OS have pkg-config in their repository. You must install pkg-config manually (using the distro package manager) as it's not installed by default when you install other devel packages. If so, this dependency need to be added in docs.

The main idea of using pkg-config is to have dynamic cflags and libs on any POSIX OS I guess.

So for me, the best strategy would be to add LDLIBS in Makefile using pkg-config (after CINC and at link time):

CINC   = -I./ `pkg-config --cflags freetype2` `pkg-config --cflags x11` `pkg-config --cflags fontconfig` `pkg-config --cflags xcb` `pkg-config --cflags expat` `pkg-config --cflags libpng` `pkg-config --cflags xinerama` `pkg-config --cflags xrender` `pkg-config --cflags xft` `pkg-config --cflags xdmpc` `pkg-config --cflags xext` `pkg-config --cflags gtk+-3.0` `pkg-config --cflags libnotify`

LDLIBS = `pkg-config --libs freetype2` `pkg-config --libs x11` `pkg-config --libs fontconfig` `pkg-config --libs xcb` `pkg-config --libs expat` `pkg-config --libs libpng` `pkg-config --libs xinerama` `pkg-config --libs xrender` `pkg-config --libs xft` `pkg-config --libs xdmpc` `pkg-config --libs xext` `pkg-config --libs gtk+-3.0` `pkg-config --libs libnotify` -lbz2 -lpthread -ldl -lrt -lz

That way, it easier for external script like domake to change Makefiles configuration dynamically using its own CINC and LDLIBS.

Note: It would be even more fun to use Flags to switch Makefile from one configuration to another but my investigation in this area showed several flows because of POSIX gmake differences between OS.

You must install pkg-config manually (using the distro package manager) as it's not installed by default when you install other devel packages.

I do not think this is correct. I believe it really is present always - I mean like "bash level" kind of presence...

Which makes sense, as its infrastructure is precursor to packaging systems....

Example on Fedora:

$ lsb_release -sir
Fedora 31

$ rpm -q --whatrequires pkg-config
no package requires pkg-config

$ rpm -qa | grep devel | wc -l
114

So on a full Fedora installation with all U++ dependencies installed and much more... not a single package requires pkg-config.
So no, you need to manually install pkg-config on most POSIX OS. It's not more complicated than installing other U++ build dependencies.

Hello amrein,

IIRC, Fedora uses the pkgconf package for some time (circa F26?), which in turn uses the pkgconf-pkg-config package to replace pkg-config links.

Can you check that?

Packages list requiring the pkg-conf-pkg-config package is long (see "Required by" section)

https://fedora.pkgs.org/31/fedora-x86_64/pkgconf-pkg-config- 1.6.3-2.fc31.x86_64.rpm.html

Best regards,
Oblivion.
