Invokes the virtual render function of the CellRenderer. The three passed-in rectangles are areas in @cr. Most renderers will draw within @cell_area; the xalign, yalign, xpad, and ypad fields of the CellRenderer should be honored with respect to @cell_area. @background_area includes the blank space around the cell, and also the area containing the tree expander; so the @background_area rectangles for all cells tile to cover the entire @window.

§cell_area

cell area as passed to gtk_cell_renderer_render()

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

👎Deprecated: Since 4.10

This signal gets emitted when the user cancels the process of editing a cell. For example, an editable cell renderer could be written to cancel editing when the user presses Escape.

See also: gtk_cell_renderer_stop_editing().

Source

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

👎Deprecated: Since 4.10

This signal gets emitted when a cell starts to be edited. The intended use of this signal is to do special setup on @editable, e.g. adding a EntryCompletion or setting up additional columns in a ComboBox.

See gtk_cell_editable_start_editing() for information on the lifecycle of the @editable and a way to do setup that doesn’t depend on the @renderer.

Note that GTK doesn’t guarantee that cell renderers will continue to use the same kind of widget for editing in future releases, therefore you should check the type of @editable before doing any specific setup, as in the following example:

⚠️ The following code is in C ⚠️

static void
text_editing_started (GtkCellRenderer *cell,
                      GtkCellEditable *editable,
                      const char      *path,
                      gpointer         data)
{
  if (GTK_IS_ENTRY (editable))
    {
      GtkEntry *entry = GTK_ENTRY (editable);

      // ... create a GtkEntryCompletion

      gtk_entry_set_completion (entry, completion);
    }
}
§editable

the CellEditable

§path

the path identifying the edited cell

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
