Required methods

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 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

a CellRenderer

attribute

an attribute on the renderer

column

the column position on the model to get the attribute from

fn clear(&self)

Unsets all the mappings on all renderers on self and removes all renderers from self.

fn clear_attributes<P: IsA<CellRenderer>>(&self, cell: &P)

Clears all existing attributes previously set with CellLayout::set_attributes.

cell

a CellRenderer to clear the attribute mapping on

fn get_area(&self) -> Option<CellArea>

Returns the underlying CellArea which might be self if called on a CellArea or might be None if no CellArea is used by self.

Returns

the cell area used by self, or None in case no cell area is used.

fn get_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 glib::List::free when no longer needed.

fn pack_end<P: IsA<CellRenderer>>(&self, cell: &P, 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

a CellRenderer

expand

true if cell is to be given extra space allocated to self

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

a CellRenderer

expand

true if cell is to be given extra space allocated to self

fn reorder<P: IsA<CellRenderer>>(&self, cell: &P, 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

fn set_cell_data_func<P: IsA<CellRenderer>>(
    &self,
    cell: &P,
    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

a CellRenderer

func

the GtkCellLayoutDataFunc to use, or None

func_data

user data for func

destroy

destroy notify for func_data
