Required Methods
sourcefn add_attribute(
&self,
cell: &impl IsA<CellRenderer>,
attribute: &str,
column: i32
)
fn add_attribute(
&self,
cell: &impl IsA<CellRenderer>,
attribute: &str,
column: i32
)
Adds an attribute mapping to the list in self
.
The column
is the column of the model to get a value from, and the
attribute
is the parameter on cell
to be set from the value. So for
example if column 2 of the model contains strings, you could have the
“text” attribute of a CellRendererText
get its values from column 2.
cell
attribute
an attribute on the renderer
column
the column position on the model to get the attribute from
sourcefn clear(&self)
fn clear(&self)
Unsets all the mappings on all renderers on self
and
removes all renderers from self
.
sourcefn clear_attributes(&self, cell: &impl IsA<CellRenderer>)
fn clear_attributes(&self, cell: &impl IsA<CellRenderer>)
Clears all existing attributes previously set with
gtk_cell_layout_set_attributes()
.
cell
a CellRenderer
to clear the attribute mapping on
sourcefn cells(&self) -> Vec<CellRenderer>
fn cells(&self) -> Vec<CellRenderer>
Returns the cell renderers which have been added to self
.
Returns
a list of cell renderers. The list, but not the renderers has
been newly allocated and should be freed with g_list_free()
when no longer needed.
sourcefn pack_end(&self, cell: &impl IsA<CellRenderer>, expand: bool)
fn pack_end(&self, cell: &impl IsA<CellRenderer>, expand: bool)
Adds the cell
to the end of self
. If expand
is false
, then the
cell
is allocated no more space than it needs. Any unused space is
divided evenly between cells for which expand
is true
.
Note that reusing the same cell renderer is not supported.
cell
expand
true
if cell
is to be given extra space allocated to self
sourcefn pack_start(&self, cell: &impl IsA<CellRenderer>, expand: bool)
fn pack_start(&self, cell: &impl IsA<CellRenderer>, expand: bool)
Packs the cell
into the beginning of self
. If expand
is false
,
then the cell
is allocated no more space than it needs. Any unused space
is divided evenly between cells for which expand
is true
.
Note that reusing the same cell renderer is not supported.
cell
expand
true
if cell
is to be given extra space allocated to self
sourcefn reorder(&self, cell: &impl IsA<CellRenderer>, position: i32)
fn reorder(&self, cell: &impl IsA<CellRenderer>, position: i32)
Re-inserts cell
at position
.
Note that cell
has already to be packed into self
for this to function properly.
cell
a CellRenderer
to reorder
position
new position to insert cell
at
sourcefn set_cell_data_func(
&self,
cell: &impl IsA<CellRenderer>,
func: Option<Box_<dyn Fn(&CellLayout, &CellRenderer, &TreeModel, &TreeIter) + 'static>>
)
fn set_cell_data_func(
&self,
cell: &impl IsA<CellRenderer>,
func: Option<Box_<dyn Fn(&CellLayout, &CellRenderer, &TreeModel, &TreeIter) + 'static>>
)
Sets the GtkCellLayoutDataFunc
to use for self
.
This function is used instead of the standard attributes mapping
for setting the column value, and should set the value of self
’s
cell renderer(s) as appropriate.
func
may be None
to remove a previously set function.
cell
func
the GtkCellLayoutDataFunc
to use, or None
func_data
user data for func
