fn copy_context<P: IsA<CellAreaContext>>(
    &self,
    context: &P
) -> Option<CellAreaContext>

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, 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. 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.

context

the CellAreaContext to copy

Returns

a newly created CellAreaContext copy of context.

fn create_context(&self) -> Option<CellAreaContext>

Creates a CellAreaContext to be used with self for all purposes. 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 CellAreaContext which was used to request the size of those rows of data).

Returns

a newly created CellAreaContext which can be used with self.

fn event<P: IsA<CellAreaContext>, Q: IsA<Widget>>(

the CellAreaContext for this row of data.

widget

the GdkEvent to handle

cell_area

the widget relative coordinates for self

flags

Returns

true if the event was handled by self.

fn focus(&self, direction: DirectionType) -> bool

This should be called by the self’s owning layout widget when focus is to be passed to self, or moved within self for a given direction and row data.

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

Returns

true if focus remains inside self as a result of this call.

) -> Option<CellRenderer>

This is handy for CellArea 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.

renderer

the CellRenderer

    &self,
    context: &P,
    widget: &Q
) -> (i32, i32)

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

self 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 CellAreaContextExt::get_preferred_height after a series of requests.

self stores some geometrical information in context along the way while calling CellAreaExt::get_preferred_width. It’s important to perform a series of CellAreaExt::get_preferred_width requests with context first and then call CellAreaExt::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 CellAreaExt::get_preferred_width again and then the full width of the requested rows checked again with CellAreaContextExt::get_preferred_width.

) -> (i32, i32)

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

) -> (i32, i32)

Retrieves a cell area’s minimum and natural width if it would be given the specified height.

self stores some geometrical information in context along the way while calling CellAreaExt::get_preferred_height. It’s important to perform a series of CellAreaExt::get_preferred_height requests with context first and then call CellAreaExt::get_preferred_width_for_height on each cell area individually to get the height for width of each fully requested row.

If at some point, the height of a single row changes, it should be requested with CellAreaExt::get_preferred_height again and then the full height of the requested rows checked again with CellAreaContextExt::get_preferred_height.

    f: F
) -> SignalHandlerId

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.

renderer

the CellRenderer that has focus

path

the current TreePath string set for area

fn connect_remove_editable<F: Fn(&Self, &CellRenderer, &CellEditable) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

Indicates that editing finished on renderer and that editable should be removed from the owning cell-layouting widget.

renderer

the CellRenderer that finished editeding

editable

the CellEditable widget to remove
