The nested window was not modal, causing it to be
inoperable. And the nested views within were all
shrunk down to nothingness. Give them some width.
Fixes: #3257
In 99.9% of all cases, these are just NULL, NULL.
So just do away with these arguments, people can
use the setters for the rare cases where they want
the scrolled window to use a different adjustment.
This commit is porting GtkPaned to be derived
from GtkWidget instead of GtkContainer, while adding
start-child and end-child properties. The existing
properties are renamed to follow the start/end naming
scheme, and we add proper getters and setters.
Update all users.
See #2719
This changes gtk_text_buffer_insert_texture() to
gtk_text_buffer_insert_paintable() which is strictly more useful
(as textures are paintables). It also fixes the code to actually
support drawing the paintables (as well as tracking changes
to the paintables.
If icon lookup fails or if loading it fails later, just always
fall back to the built in image-missing icon. Nobody is handling
missing icons in a sane way anyway.
If you *truly* need to handle missing icons, you need to manually
use gtk_icon_theme_has_icon().
While changing the loading code I also fixed an issue where it
was always passing "png" to pixbuf, now it also handles "xpm" if
that is the filename suffix.
Instead, rely on people passing fallbacks explicitly.
Alternatively, GThemedIcon provides the functionality to create
fallbacks, which is what GtkImage and the testsuite now use.
That method is slightly better, too, so the expected test results
have been updated accordingly.
Most users were just forgetting to set the proper flags.
And flags aren't the right way to set this anyway, it was just
acceptable as a workaround during GTK3 to not break API.
The API encouraged wrong usage - most of the users were indeed wrong.
Use the correct version instead:
gtk_icon_theme_get_for_display (gtk_widget_get_display ())
This affects a few apis, such as gtk_text_iter_get_pixbuf,
gtk_text_buffer_insert_pixbuf and GtkTextBuffer::insert-pixbuf,
which have all been replaced by texture equivalents.
Update all callers.
And have a priv->display instead of a priv->screen.
Includes turning gtk_menu_set_screen() into gtk_menu_set_display(),
because that function just forwards to its window.
"Hey I know, let's do an easter egg!"
"What kind of easter egg?"
"We can nest lots of textviews!"
"Sounds cool!"
...
"But how does one see a textview inside a textview?"
"What do you mean?"
"Well, it just looks like black text on a white background."
"You mean it's the same as if we just duplicated the text?"
"Yeah!"
"Hrm, maybe we can put a frame around it."
"Sounds good. I'll stuff the textviews in a GtkFrame."
"What? Why? Let's use a GtkEventBox and override its background"
"Why is that a good idea when we have GtkFrame?"
"Because I said so!"
"Okay."
