Struct gtk::CellRendererPixbuf [−][src]
pub struct CellRendererPixbuf(_);
Expand description
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
property::CellRendererPixbuf::pixbuf
property) or a named icon (set via the
property::CellRendererPixbuf::icon-name
property).
To support the tree view, CellRendererPixbuf
also supports rendering two
alternative pixbufs, when the property::CellRenderer::is-expander
property is true
.
If the property::CellRenderer::is-expanded
property is true
and the
property::CellRendererPixbuf::pixbuf-expander-open
property is set to a pixbuf, it
renders that pixbuf, if the property::CellRenderer::is-expanded
property is false
and the property::CellRendererPixbuf::pixbuf-expander-closed
property is set to a
pixbuf, it renders that one.
Implements
CellRendererPixbufExt
, CellRendererExt
, glib::ObjectExt
, CellRendererPixbufExtManual
Implementations
Creates a new CellRendererPixbuf
. Adjust rendering
parameters using object properties. Object properties can be set
globally (with [ObjectExtManual::set()
][crate::glib::prelude::ObjectExtManual::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.
