描述
这是接口，不可以直接访问。
The GtkEditable interface is an interface which should be implemented by text editing widgets, such as GtkEntry and GtkText. It contains functions for generically manipulating an editable widget, a large number of action signals used for key bindings, and several signals that an application can connect to to modify the behavior of a widget.
As an example of the latter usage, by connecting the following handler to "insert-text", an application can convert all entry into a widget into uppercase.
方法
copy_clipboard() Copy the current selection into clipboard. cut_clipboard() Copy the current selection into clipboard & delete. delete_selection() Deletes the current contents of the selection. delete_text() Deletes a sequence of characters. get_chars() Retrieves a sequence of characters. get_editable() If the text can be changed. get_position() Retrieves the current cursor position. get_selection_bounds() Gets the current selection bounds. insert_text() Inserts text at a given position. paste_clipboard() Paste the clipboard contents at the current cursor position. select_region() Selects a part of the text. set_editable() If the user can edit the text in the editable widget. set_position() Sets the cursor position.
