GInterface +----GtkEditable
GtkEditable is implemented by
GtkEntry, GtkText, GtkOldEditable and GtkSpinButton.
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.
Forcing entry to uppercase.
insert_text_handler <- function(editable, text, length, position, id)
{
result <- toupper(text)
gSignalHandlerBlock(editable, id)
editable$insertText(result, length, position)
gSignalHandlerUnblock(editable, id)
}
GtkEditableGtkEditable structure contains the following fields.
(These fields should be considered read-only. They should
never be set by an application.)
numeric selection_start; | the starting position of the selected characters in the widget. |
numeric selection_end; | the end position of the selected characters in the widget. |
numeric editable; | a flag indicating whether or not the widget is editable by the user. |
