CellRendererSpinSignalName

This signal is emitted after renderer has been edited.

It is the responsibility of the application to update the model and store new_text at the position indicated by path.

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().

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 GtkEntryCompletion or setting up additional columns in a GtkComboBox.

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: (C Language Example):

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);
    }
}

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

(C Language Example):

g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

It is important to note that you must use canonical parameter names as detail strings for the notify signal.

The adjustment that holds the value of the spinbutton. This must be non-nil for the cell renderer to be editable.

Specifies how to align the lines of text with respect to each other.

Note that this property describes how to align the lines of text in case there are several of them. The “xalign” property of GtkCellRenderer, on the other hand, sets the horizontal alignment of the whole text.

Specifies the preferred place to ellipsize the string, if the cell renderer does not have enough room to display the entire string. Setting it to PANGO_ELLIPSIZE_NONE turns off ellipsizing. See the wrap-width property for another way of making the text fit into a given width.

The desired maximum width of the cell, in characters. If this property is set to -1, the width will be calculated automatically.

For cell renderers that ellipsize or wrap text; this property controls the maximum reported width of the cell. The cell should not receive any greater allocation unless it is set to expand in its GtkCellLayout and all of the cell’s siblings have received their natural width.

Undocumented

The text that will be displayed in the GtkCellRenderer if GtkCellRendererText:editable is true and the cell is empty.

The desired width of the cell, in characters. If this property is set to -1, the width will be calculated automatically, otherwise the cell will request either 3 characters or the property value, whichever is greater.

Specifies how to break the string into multiple lines, if the cell renderer does not have enough room to display the entire string. This property has no effect unless the wrap-width property is set.

Specifies the minimum width at which the text is wrapped. The wrap-mode property can be used to influence at what character positions the line breaks can be placed. Setting wrap-width to -1 turns wrapping off.
