Detailed Description

An abstract base class for laying out CellRenderers.

This is an abstract base class for CellLayout widgets (also referred to as "layouting widgets") to interface with an arbitrary number of CellRenderers and interact with the user for a given TreeModel row.

The cell area handles events, focus navigation, drawing and size requests and allocations for a given row of data.

Usually users dont have to interact with the CellArea directly unless they are implementing a cell layouting widget themselves.

Requesting area sizes

As outlined in Gtk::Widget's geometry management description, GTK+ uses a height-for-width geometry management system to compute the sizes of widgets and user interfaces. CellArea uses the same semantics to calculate the size of an area for an arbitrary number of TreeModel rows.

When requesting the size of a cell area one needs to calculate the size for a handful of rows, and this will be done differently by different layouting widgets. For instance a TreeViewColumn always lines up the areas from top to bottom while an IconView, on the other hand, might enforce that all areas received the same width and wrap the areas around, requesting height for more cell areas when allocated less width.

It's also important for areas to maintain some cell alignments with areas rendered for adjacent rows (cells can appear "columnized" inside an area even when the size of cells are different in each row). For this reason the CellArea uses a CellAreaContext object to store the alignments and sizes along the way (as well as the overall largest minimum and natural size for all the rows which have been calculated with the said context).

The CellAreaContext is an opaque object specific to the CellArea which created it (see CellArea::create_context()). The owning cell-layouting widget can create as many contexts as it wishes to calculate sizes of rows which should receive the same size in at least one orientation (horizontally or vertically). However, it's important that the same CellAreaContext which was used to request the sizes for a given TreeModel row be used when rendering or processing events for that row.

Cell Properties

The CellArea introduces cell properties for CellRenderers in very much the same way that Gtk::Container introduces child properties for Widgets. This provides some general interfaces for defining the relationship cell areas have with their cells. For instance in a CellAreaBox a cell might "expand" and receive extra space when the area is allocated more than its full natural request, or a cell might be configured to "align" with adjacent rows which were requested and rendered with the same CellAreaContext.

To set the value of a cell property, use cell_set_property(). To obtain the value of a cell property, use cell_get_property().

◆ copy_context()

Glib::RefPtr< CellAreaContext > Gtk::CellArea::copy_context ( const Glib::RefPtr< const CellAreaContext > & context )

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, Gtk::IconView 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. Gtk::IconView 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.

Since gtkmm 3.0:

Parameters

Returns: A newly created Gtk::CellAreaContext copy of context.

◆ create_context()

Glib::RefPtr< CellAreaContext > Gtk::CellArea::create_context ( ) const

Creates a Gtk::CellAreaContext to be used with area for all purposes.

Gtk::CellAreaContext 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 Gtk::CellAreaContext which was used to request the size of those rows of data).

Since gtkmm 3.0:

Returns: A newly created Gtk::CellAreaContext which can be used with area.

◆ event()

widget	The Gtk::Widget that area is rendering to.
gdk_event	The Gdk::Event to handle.
cell_area	The widget relative coordinates for area.
flags	The Gtk::CellRendererState for area in this row.

Returns: true if the event was handled by area.

◆ focus()

bool Gtk::CellArea::focus ( DirectionType direction )

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 Gtk::CellArea classes should implement this method to receive and navigate focus in its own way particular to how it lays out cells.

Since gtkmm 3.0:

Parameters

direction The Gtk::DirectionType.

Returns: true if focus remains inside area as a result of this call.

◆ foreach() [1/2]

		Widget &	widget,
		int &	minimum_height,
		int &	natural_height
	)

Retrieves a cell area’s initial minimum and natural height.

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_height and natural_height of this call but rather to consult Gtk::CellAreaContext::get_preferred_height() after a series of requests.

Since gtkmm 3.0:

Parameters

context	The Gtk::CellAreaContext to perform this request with.
widget	The Gtk::Widget where area will be rendering.
minimum_height	Location to store the minimum height, or `nullptr`.
natural_height	Location to store the natural height, or `nullptr`.

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 get_preferred_width().

Parameters

context	The Gtk::CellAreaContext which has already been requested for widths.
widget	The Gtk::Widget where area will be rendering.
width	The width for which to check the height of this area.

Flags: Run First

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 gtkmm 3.0:

Parameters

renderer	The Gtk::CellRenderer that has focus.
path	The current Gtk::TreePath string set for area.

renderer	The Gtk::CellRenderer that finished editeding.
editable	The Gtk::CellEditable widget to remove.

◆ stop_editing()

void Gtk::CellArea::stop_editing ( bool canceled )

See get_edited_cell() and get_edit_widget().

Since gtkmm 3.0:

Parameters

canceled Whether editing was canceled.
