public class CellAreaContext : Object

The CellAreaContext object is created by a given CellArea implementation via its create_context virtual method and is used to store cell sizes and alignments for a series of TreeModel rows that are requested and rendered in the same context.

CellLayout 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 TreeModel row also be used for the same row when calling other CellArea APIs such as render and event.

Properties:

public CellArea area { get; construct; }
The CellArea this context was created by
public int minimum_height { get; }
The minimum height for the CellArea in this context for all TreeModel rows that this context was requested for using get_preferred_height.
public int minimum_width { get; }
The minimum width for the CellArea in this context for all TreeModel rows that this context was requested for using get_preferred_width.
public int natural_height { get; }
The natural height for the CellArea in this context for all TreeModel rows that this context was requested for using get_preferred_height.
public int natural_width { get; }
The natural width for the CellArea in this context for all TreeModel rows that this context was requested for using get_preferred_width.

Creation methods:

protected CellAreaContext ()

Methods:

public virtual void allocate (int width, int height)
Allocates a width and/or a height for all rows which are to be rendered with this.
public void get_allocation (out int width, out int height)
Fetches the current allocation size for this .
public unowned CellArea get_area ()
Fetches the CellArea this this was created by.
public void get_preferred_height (out int minimum_height, out int natural_height)
Gets the accumulative preferred height for all rows which have been requested with this context.
public virtual void get_preferred_height_for_width (int width, out int minimum_height, out int natural_height)
Gets the accumulative preferred height for width for all rows which have been requested for the same said width with this context.
public void get_preferred_width (out int minimum_width, out int natural_width)
Gets the accumulative preferred width for all rows which have been requested with this context.
public virtual void get_preferred_width_for_height (int height, out int minimum_width, out int natural_width)
Gets the accumulative preferred width for height for all rows which have been requested for the same said height with this context.
public void push_preferred_height (int minimum_height, int natural_height)
Causes the minimum and/or natural height to grow if the new proposed sizes exceed the current minimum and natural height.
public void push_preferred_width (int minimum_width, int natural_width)
Causes the minimum and/or natural width to grow if the new proposed sizes exceed the current minimum and natural width.
public virtual void reset ()
Resets any previously cached request and allocation data.
