GtkEditable is implemented by GtkEntry, GtkOldEditable, GtkSpinButton and GtkText.

Detailed Description

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) }
