This is used by CellArea subclasses when handling events
to activate cells, the base CellArea class activates cells
for keyboard events for free in its own GtkCellArea->activate()
implementation.
widget
the Widget that self is rendering onto
renderer
the CellRenderer in self to activate
event
the gdk::Event for which cell activation should occur
cell_area
the gdk::Rectangle in widget relative coordinates
of renderer for the current row.
flags
the CellRendererState for renderer
Returns
whether cell activation was successful
Delegates event handling to a CellArea.
context
the CellAreaContext for this row of data.
widget
the Widget that self is rendering to
event
the gdk::Event to handle
cell_area
the widget relative coordinates for self
flags
the CellRendererState for self in this row.
Returns
true if the event was handled by self.
Gets the values of one or more cell properties for renderer in self.
renderer
a CellRenderer which is inside self
first_prop_name
the name of the first cell property to get
Sets one or more cell properties for cell in self.
renderer
a CellRenderer which is a cell inside self
first_prop_name
the name of the first cell property to set
