GTK+, The GIMP ToolKit
Cross-platform Graphical User Interface library
Website: http://www.gtk.org
Platforms supported: Win32, Linux, FreeBSD
Headers to include: gtk/gtk.bi
Example Usage: yes, in examples/GUI/GTK+/
Header version: 2.24.27, 3.14.10
By default, gtk/gtk.bi will use the GTK+ 2 API.
Define __USE_GTK3__ before including gtk/gtk.bi to use GTK+ 3.
GObject property setters are variadic C calls: pass the type declared for each property. A double property needs a Double expression, not an Integer. Use CTRUE (1) for boolean properties; FreeBASIC TRUE (-1) can be rejected by property validation. In the GooCanvas table example, the width_TJF parameter must supply the width property, rather than BASIC's WIDTH function.
The Linux GTK example runner checks the original GTK 2, GTK 3 and GooCanvas windows on isolated, authenticated Xvfb displays, including normal window closure. It stages each example's assets, tests all three packing layouts and opens a text fixture in the application example. GooCanvas checks also drag the arrow-width handle and verify keyboard focus events. Software OpenGL and these headless windows do not establish accelerated GPU or physical display operation. See build_scripts/test-gtk-examples.py and doc/linux-example-qualification.md.
On FreeBSD, the manual GTK 2 window example exited under Xvfb and linked GTK 2.
The synthetic close emitted a Gdk-WARNING when the headless server destroyed
the window. GTK 3 and GooCanvas runtime behavior remains unqualified.
