Struct gtk4::IconPaintable [−][src]
pub struct IconPaintable(_);Expand description
Contains information found when looking up an icon in IconTheme.
IconPaintable implements gdk::Paintable.
Implements
Implementations
Creates a IconPaintable for a file with a given size and scale.
The icon can then be rendered by using it as a gdk::Paintable.
file
a GFile
size
desired icon size
scale
the desired scale
Returns
a IconPaintable containing
for the icon. Unref with g_object_unref()
Creates a new builder-pattern struct instance to construct IconPaintable objects.
This method returns an instance of IconPaintableBuilder which can be used to create IconPaintable objects.
Get the icon name being used for this icon.
When an icon looked up in the icon theme was not available, the
icon theme may use fallback icons - either those specified to
IconTheme::lookup_icon() or the always-available
“image-missing”. The icon chosen is returned by this function.
If the icon was created without an icon theme, this function
returns None.
Returns
the themed icon-name for the
icon, or None if its not a themed icon.
Checks if the icon is symbolic or not.
This currently uses only the file name and not the file contents for determining this. This behaviour may change in the future.
Note that to render a symbolic IconPaintable properly (with
recoloring), you have to set its icon name on a Image.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
