Struct gtk4::CellAreaBox [−][src]
pub struct CellAreaBox(_);Expand description
A cell area that renders GtkCellRenderers into a row or a column
The CellAreaBox renders cell renderers into a row or a column
depending on its Orientation.
GtkCellAreaBox uses a notion of packing. Packing
refers to adding cell renderers with reference to a particular position
in a CellAreaBox. There are two reference positions: the
start and the end of the box.
When the CellAreaBox is oriented in the Orientation::Vertical
orientation, the start is defined as the top of the box and the end is
defined as the bottom. In the Orientation::Horizontal orientation
start is defined as the left side and the end is defined as the right
side.
Alignments of CellRenderers rendered in adjacent rows can be
configured by configuring the CellAreaBox align child cell property
with [CellAreaExtManual::cell_set_property()][crate::prelude::CellAreaExtManual::cell_set_property()] or by specifying the “align”
argument to pack_start() and pack_end().

Implementations
Creates a new builder-pattern struct instance to construct CellAreaBox objects.
This method returns an instance of CellAreaBoxBuilder which can be used to create CellAreaBox objects.
Gets the spacing added between cell renderers.
Returns
the space added between cell renderers in self.
Adds renderer to self, packed with reference to the end of self.
The renderer is packed after (away from end of) any other
CellRenderer packed with reference to the end of self.
renderer
the CellRenderer to add
expand
whether renderer should receive extra space when the area receives
more than its natural size
align
whether renderer should be aligned in adjacent rows
fixed
whether renderer should have the same size in all rows

Adds renderer to self, packed with reference to the start of self.
The renderer is packed after any other CellRenderer packed
with reference to the start of self.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
