* the current selection if one exists.
|
||
* @toggle_overwrite: Class handler for the #GtkEntry::toggle-overwrite signal.
|
||
* The default implementation toggles overwrite mode and blinks the cursor.
|
||
* @get_text_area_size: Calculate the size of the text area, which is its

* allocated width and requested height, minus space for margins and borders.
|

* This virtual function must be non-%NULL.
|
||
* @get_frame_size: Calculate the size of the text area frame, which is its

* allocated width and requested height, minus space for margins and borders,
|
||
* and taking baseline and text height into account. This virtual function
|
||
* must be non-%NULL.
