CellAreaContext

open class CellAreaContext(pointer: <Error class: unknown class><<Error class: unknown class>>)

Stores geometrical information for a series of rows in a GtkCellArea

The GtkCellAreaContext object is created by a given GtkCellArea implementation via its GtkCellAreaClass.create_context() virtual method and is used to store cell sizes and alignments for a series of GtkTreeModel rows that are requested and rendered in the same context.

GtkCellLayout widgets can create any number of contexts in which to request and render groups of data rows. However, it’s important that the same context which was used to request sizes for a given GtkTreeModel row also be used for the same row when calling other GtkCellArea APIs such as gtk_cell_area_render() and gtk_cell_area_event().

Functions

allocate

open fun allocate(width: Int, height: Int)

Allocates a width and/or a height for all rows which are to be rendered with @context.

getArea

open fun getArea(): CellArea

Fetches the GtkCellArea this @context was created by.

pushPreferredHeight

open fun pushPreferredHeight(minimumHeight: Int, naturalHeight: Int)

Causes the minimum and/or natural height to grow if the new proposed sizes exceed the current minimum and natural height.

pushPreferredWidth

open fun pushPreferredWidth(minimumWidth: Int, naturalWidth: Int)

Causes the minimum and/or natural width to grow if the new proposed sizes exceed the current minimum and natural width.

reset

open fun reset()

Resets any previously cached request and allocation data.
