GdkMemoryTexture is a texture implementation for holding data in memory
(read: GBytes). You specify the GdkMemoryFormat that data is in and off
you go.
Renderers can use this to add uploads in various different formats and
don't need to fallback to GDK doing the conersion on the CPU.
Supported formats can be extended if we need new ones, for now I just
added the relevant ones for Cairo and GdkPixbuf.
The constructor is also private still, because I'm not sure we want to
export GdkMemoryFormat.
Wrappers that do from_cairo_surface() and for_pixbuf() do exist though.
Put GdkGLTexture into its own file and rename the API to
gdk_gl_texture_foo() instead of gdk_texture_foo_for_gl().
Apart from naming, no actual code changes.
GIO has this facility, so we should use it.
At the same time, make sure the immodules directory
exists, even if we don't install any modules there
outselves.
Now that GtkExpander subclasses GtkContainer instead of GtkBin, it needs
its own guard against adding more than one child.
Also, the documentation should no longer describe adding a child as if
it is descended from GtkBin.
We can't use gtk_widget_get_allocation for either non-anchored widgets
(which happens with the child widget when the expander is unexpanded)
nor toplevel windows since that will include the window decorations.
Fixes#70 in gtk4
We are creating these using g_object_new, so the _new function is never
called, resulting in a NULL mb_charset. Fix this by moving the
initialisation into the _init function.
An alternative GskTextNode constructor that does no text measuring. That
way, we can measure the text before and check if the node will be
outside of the current clip anyway.
This was just testing that text nodes do alpha correctly, but the test
even breaks if the default font is different from the one that was used
to create the reference image, so drop it for now.
gtk_im_context_set_client_widget() allows passing NULL as widget to signal that
the widget no longer exists. The xim implementation didn't handle that
case which led to the test suite on gitlab-ci failing.
The gir XML file contains description of types and functions from
gtk/gtk-a11y.h. Indicate that this header should be included in addition
to gtk/gtk.h in applications written in C. #56
