Description

gtkmm is the official C++ interface for the popular GUI library GTK. Highlights include typesafe callbacks, and a comprehensive set of widgets that are easily extensible via inheritance.

For instance, see Widgets, Dialogs, ListView and TextView.

See also the Programming with gtkmm book.

Features

GTK’s mature, capable set of widgets. See the GTK website for more information.
Use inheritance to derive custom widgets.
Type-safe signal handlers (slots), in standard C++, using libsigc++.
Polymorphism.
Use of the Standard C++ Library, including strings, containers and iterators.
Full internationalisation with UTF8.
Complete C++ memory management.
- Member instances or dynamic new and delete.
- Optional automatic deletion of child widgets.
- No manual reference-counting.
Full use of C++ namespaces.
No macros.

Basic Usage

Include the gtkmm header:

#include <gtkmm.h>

(You may include individual headers, such as gtkmm/button.h instead.)

If your source file is program.cc, you can compile it with:

g++ program.cc -o program `pkg-config --cflags --libs gtkmm-4.0`

If your version of g++ is not C++17-compliant by default, add the -std=c++17 option.

If you use Meson, include the following in meson.build:

gtkmm_dep = dependency('gtkmm-4.0')
program_name = 'program'
cpp_sources = [ 'program.cc' ]
executable(program_name,
  cpp_sources,
  dependencies: gtkmm_dep
)

Alternatively, if using autoconf, use the following in configure.ac:

PKG_CHECK_MODULES([GTKMM], [gtkmm-4.0])

Then use the generated GTKMM_CFLAGS and GTKMM_LIBS variables in the project Makefile.am files. For example:

program_CPPFLAGS = $(GTKMM_CFLAGS)

program_LDADD = $(GTKMM_LIBS)
