Indicates that editing has started on renderer and that editable should be added to the owning cell-layouting widget at cell_area. Since 3.0
This signal is emitted whenever applying attributes to area from model Since 3.0
Indicates that focus changed on this area. This signal is emitted either as a result of focus handling or event handling. It's possible that the signal is emitted even if the currently focused renderer did not change, this is because focus may change to the same renderer in the same cell area for a different row of data. Since 3.0
Indicates that editing finished on renderer and that editable should be removed from the owning cell-layouting widget. Since 3.0
Adds renderer to area with the default child cell properties.
Removes renderer from area.
Checks if area contains renderer.
Calls callback for every GtkCellRenderer in area.
Calls callback for every GtkCellRenderer in area with the allocated rectangle inside cell_area.
Delegates event handling to a GtkCellArea.
Renders area's cells according to area's layout onto widget at the given coordinates.
Derives the allocation of renderer inside area if area were to be renderered in cell_area.
Gets the GtkCellRenderer at x and y coordinates inside area and optionally returns the full cell allocation for it inside cell_area.
Creates a GtkCellAreaContext to be used with area for all purposes. GtkCellAreaContext stores geometry information for rows for which it was operated on, it is important to use the same context for the same row of data at all times (i.e. one should render and handle events with the same GtkCellAreaContext which was used to request the size of those rows of data).
This is sometimes needed for cases where rows need to share alignments in one orientation but may be separately grouped in the opposing orientation. For instance, GtkIconView creates all icons (rows) to have the same width and the cells theirin to have the same horizontal alignments. However each row of icons may have a separate collective height. GtkIconView uses this to request the heights of each row based on a context which was already used to request all the row widths that are to be displayed.
Gets whether the area prefers a height-for-width layout or a width-for-height layout.
Retrieves a cell area's initial minimum and natural width. area will store some geometrical information in context along the way; when requesting sizes over an arbitrary number of rows, it's not important to check the minimum_width and natural_width of this call but rather to consult gtk_cell_area_context_get_preferred_width() after a series of requests.
Retrieves a cell area's minimum and natural height if it would be given the specified width. area stores some geometrical information in context along the way while calling gtk_cell_area_get_preferred_width(). It's important to perform a series of gtk_cell_area_get_preferred_width() requests with context first and then call gtk_cell_area_get_preferred_height_for_width() on each cell area individually to get the height for width of each fully requested row. If at some point, the width of a single row changes, it should be requested with gtk_cell_area_get_preferred_width() again and then the full width of the requested rows checked again with gtk_cell_area_context_get_preferred_width().

Gets the current GtkTreePath string for the currently applied GtkTreeIter, this is implicitly updated when gtk_cell_area_apply_attributes() is called and can be used to interact with renderers from GtkCellArea subclasses.
Applies any connected attributes to the renderers in area by pulling the values from tree_model.
Connects an attribute to apply values from column for the GtkTreeModel in use.
Disconnects attribute for the renderer in area so that attribute will no longer be updated with values from the model.
Installs a cell property on a cell area class.
Finds a cell property of a cell area class by name.
Returns all cell properties of a cell area class.
Sets one or more cell properties for renderer in area.
Gets the values of one or more cell properties for renderer in area.
Sets a cell property for renderer in area.
Gets the value of a cell property for renderer in area.
Returns whether the area can do anything when activated, after applying new attributes to area.
Activates area, usually by activating the currently focused cell, however some subclasses which embed widgets in the area can also activate a widget if it currently has the focus.
This should be called by the area's owning layout widget when focus is to be passed to area, or moved within area for a given direction and row data. Implementing GtkCellArea classes should implement this method to receive and navigate focus in its own way particular to how it lays out cells.
Explicitly sets the currently focused cell to renderer. This is generally called by implementations of GtkCellAreaClass.focus() or GtkCellAreaClass.event(), however it can also be used to implement functions such as gtk_tree_view_set_cursor_on_cell().
Retrieves the currently focused cell for area
Adds sibling to renderer's focusable area, focus will be drawn around renderer and all of its siblings if renderer can focus for a given row. Events handled by focus siblings can also activate the given focusable renderer.
Removes sibling from renderer's focus sibling list (see gtk_cell_area_add_focus_sibling()).
Returns whether sibling is one of renderer's focus siblings (see gtk_cell_area_add_focus_sibling()).
Gets the focus sibling cell renderers for renderer.
Gets the GtkCellRenderer which is expected to be focusable for which renderer is, or may be a sibling. This is handy for GtkCellArea subclasses when handling events, after determining the renderer at the event location it can then chose to activate the focus cell for which the event cell may have been a sibling.
Gets the GtkCellRenderer in area that is currently being edited.
Gets the GtkCellEditable widget currently used to edit the currently edited cell.
This is used by GtkCellArea subclasses when handling events to activate cells, the base GtkCellArea class activates cells for keyboard events for free in its own GtkCellArea->activate() implementation.
Explicitly stops the editing of the currently edited cell. If canceled is TRUE, the currently edited cell renderer will emit the ::editing-canceled signal, otherwise the the ::editing-done signal will be emitted on the current edit widget. See gtk_cell_area_get_edited_cell() and gtk_cell_area_get_edit_widget().
This is a convenience function for GtkCellArea implementations to get the inner area where a given GtkCellRenderer will be rendered. It removes any padding previously added by gtk_cell_area_request_renderer().
This is a convenience function for GtkCellArea implementations to request size for cell renderers. It's important to use this function to request size and then use gtk_cell_area_inner_cell_area() at render and event time since this function will add padding around the cell for focus painting.

Retrieves the orientation of the orientable. Since 2.16
Sets the orientation of the orientable. Since 2.16
The GtkCellAreaBox renders cell renderers into a row or a column depending on its GtkOrientation.
GtkCellAreaBox uses a notion of packing. Packing refers to adding cell renderers with reference to a particular position in a GtkCellAreaBox. There are two reference positions: the start and the end of the box. When the GtkCellAreaBox is oriented in the GTK_ORIENTATION_VERTICAL orientation, the start is defined as the top of the box and the end is defined as the bottom. In the GTK_ORIENTATION_HORIZONTAL orientation start is defined as the left side and the end is defined as the right side.
Alignments of GtkCellRenderers rendered in adjacent rows can be configured by configuring the "align" child cell property with gtk_cell_area_cell_set_property() or by specifying the "align" argument to gtk_cell_area_box_pack_start() and gtk_cell_area_box_pack_end().
