Detail
The EntryBuffer class contains the actual text displayed in a Entry
widget.
A single EntryBuffer object can be shared by multiple Entry widgets
which will then share the same text content, but not the cursor position,
visibility attributes, icon etc.
EntryBuffer may be derived from. Such a derived class might allow text
to be stored in an alternate location, such as non-pageable memory, useful
in the case of important passwords. Or a derived class could integrate with
an application's concept of undo/redo.

Constructors
Arguments
| :: Maybe String |
|
| -> IO EntryBuffer |
Create a new EntryBuffer object.
Optionally, specify initial text to set in the buffer.
- Available since Gtk+ version 2.18
Methods
Arguments
| :: EntryBufferClass self | |
| => self | |
| -> IO Int | returns The byte length of the buffer. |
Retrieves the length in bytes of the buffer. See entryBufferGetLength.
- Available since Gtk+ version 2.18
Arguments
| :: EntryBufferClass self | |
| => self | |
| -> Int |
|
| -> String |
|
| -> IO Int | returns The number of characters actually inserted. |
Inserts chars into the contents of the buffer,
at position position.
- Available since Gtk+ version 2.18
Arguments
| :: EntryBufferClass self | |
| => self | |
| -> Int |
|
| -> Int |
|
| -> IO Int | returns The number of characters deleted. |
Deletes a sequence of characters from the buffer. nChars characters are
deleted starting at position. If nChars is negative, then all characters
until the end of the text are deleted.
- Available since Gtk+ version 2.18
