Struct EntryBuffer 

pub struct EntryBuffer { /* private fields */ }

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.

Properties

length

The length (in characters) of the text in buffer.

Readable

max-length

The maximum length (in characters) of the text in the buffer.

Readable | Writeable

text

The contents of the buffer.

Readable | Writeable

Signals

deleted-text

This signal is emitted after text is deleted from the buffer.

inserted-text

This signal is emitted after text is inserted into the buffer.
