}Expand description

Required methods
fn add_attribute<P: IsA<CellRenderer>>(
&self,
cell: &P,
attribute: &str,
column: i32
)
fn add_attribute<P: IsA<CellRenderer>>(
&self,
cell: &P,
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 property on cell to be set from that 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.
In this context “attribute” and “property” are used interchangeably.
cell
attribute
a property on the renderer
column
the column position on the model to get the attribute from
Unsets all the mappings on all renderers on self and
removes all renderers from self.
fn clear_attributes<P: IsA<CellRenderer>>(&self, cell: &P)
fn clear_attributes<P: IsA<CellRenderer>>(&self, cell: &P)
Clears all existing attributes previously set with
gtk_cell_layout_set_attributes().
cell
a CellRenderer to clear the attribute mapping on
fn 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.
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
fn pack_start<P: IsA<CellRenderer>>(&self, cell: &P, expand: bool)
fn pack_start<P: IsA<CellRenderer>>(&self, cell: &P, 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
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
fn set_cell_data_func<P: IsA<CellRenderer>, Q: Fn(&CellLayout, &CellRenderer, &TreeModel, &TreeIter) + 'static>(
&self,
cell: &P,
func: Q
)
fn set_cell_data_func<P: IsA<CellRenderer>, Q: Fn(&CellLayout, &CellRenderer, &TreeModel, &TreeIter) + 'static>(
&self,
cell: &P,
func: Q
)
Sets the CellLayoutDataFunc 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 CellLayoutDataFunc to use
func_data
user data for func
