Class
GtkCellAreaContext
Description [src]
class Gtk.CellAreaContext : GObject.Object
{
/* No available fields */
}
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().
Instance methods
gtk_cell_area_context_allocate
Allocates a width and/or a height for all rows which are to be
rendered with context
.
gtk_cell_area_context_get_preferred_height
Gets the accumulative preferred height for all rows which have been requested with this context.
since: 3.0
gtk_cell_area_context_get_preferred_height_for_width
Gets the accumulative preferred height for width
for all rows
which have been requested for the same said width
with this context.
since: 3.0
gtk_cell_area_context_get_preferred_width
Gets the accumulative preferred width for all rows which have been requested with this context.
since: 3.0
gtk_cell_area_context_get_preferred_width_for_height
Gets the accumulative preferred width for height
for all rows which
have been requested for the same said height
with this context.
since: 3.0
gtk_cell_area_context_push_preferred_height
Causes the minimum and/or natural height to grow if the new proposed sizes exceed the current minimum and natural height.
since: 3.0
gtk_cell_area_context_push_preferred_width
Causes the minimum and/or natural width to grow if the new proposed sizes exceed the current minimum and natural width.
since: 3.0
Properties
Gtk.CellAreaContext:minimum-height
The minimum height for the GtkCellArea
in this context
for all GtkTreeModel
rows that this context was requested
for using gtk_cell_area_get_preferred_height().
since: 3.0
Gtk.CellAreaContext:minimum-width
The minimum width for the GtkCellArea
in this context
for all GtkTreeModel
rows that this context was requested
for using gtk_cell_area_get_preferred_width().
since: 3.0
Gtk.CellAreaContext:natural-height
The natural height for the GtkCellArea
in this context
for all GtkTreeModel
rows that this context was requested
for using gtk_cell_area_get_preferred_height().
since: 3.0
Gtk.CellAreaContext:natural-width
The natural width for the GtkCellArea
in this context
for all GtkTreeModel
rows that this context was requested
for using gtk_cell_area_get_preferred_width().
since: 3.0
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
