👎Deprecated: Since 4.10

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.

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);
    }
}
