Struct gtk4::EntryBuffer
source · #[repr(transparent)]pub struct EntryBuffer { /* private fields */ }
Expand description
A EntryBuffer
hold the text displayed in a Text
widget.
A single EntryBuffer
object can be shared by multiple 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
The text is altered in the default handler for this signal.
If you want access to the text after the text has been modified,
use G_CONNECT_AFTER
.
inserted-text
This signal is emitted after text is inserted into the buffer.

Implementations§
source§impl EntryBuffer
impl EntryBuffer
pub const NONE: Option<&'static EntryBuffer> = None
sourcepub fn builder() -> EntryBufferBuilder
pub fn builder() -> EntryBufferBuilder
Creates a new builder-pattern struct instance to construct EntryBuffer
objects.
This method returns an instance of EntryBufferBuilder
which can be used to create EntryBuffer
objects.
source§impl EntryBuffer
impl EntryBuffer
sourcepub fn new(initial_chars: impl IntoOptionalGStr) -> Self
pub fn new(initial_chars: impl IntoOptionalGStr) -> Self
Create a new EntryBuffer
object.
Optionally, specify initial text to set in the buffer.
initial_chars
initial buffer text
n_initial_chars
number of characters in @initial_chars, or -1
Returns
A new EntryBuffer
object.
