Struct gtk4::CellRendererPixbuf [−][src]
pub struct CellRendererPixbuf(_);Expand description
Renders a pixbuf in a cell
A CellRendererPixbuf can be used to render an image in a cell. It allows
to render either a given gdk_pixbuf::Pixbuf (set via the
GtkCellRendererPixbuf:pixbuf property) or a named icon (set via the
GtkCellRendererPixbuf:icon-name property).
To support the tree view, CellRendererPixbuf also supports rendering two
alternative pixbufs, when the GtkCellRenderer:is-expander property is true.
If the GtkCellRenderer:is-expanded property is true and the
GtkCellRendererPixbuf:pixbuf-expander-open property is set to a pixbuf, it
renders that pixbuf, if the GtkCellRenderer:is-expanded property is false
and the GtkCellRendererPixbuf:pixbuf-expander-closed property is set to a
pixbuf, it renders that one.
Implements
Implementations
Creates a new CellRendererPixbuf. Adjust rendering
parameters using object properties. Object properties can be set
globally (with g_object_set()). Also, with TreeViewColumn, you
can bind a property to a value in a TreeModel. For example, you
can bind the “pixbuf” property on the cell renderer to a pixbuf value
in the model, thus rendering a different image in each row of the
TreeView.
Returns
the new cell renderer
Creates a new builder-pattern struct instance to construct CellRendererPixbuf objects.
This method returns an instance of CellRendererPixbufBuilder which can be used to create CellRendererPixbuf objects.
The GIcon representing the icon to display. If the icon theme is changed, the image will be updated automatically.

The name of the themed icon to display. This property only has an effect if not overridden by the “pixbuf” property.
