Struct gtk4::Text

source ·
pub struct Text { /* private fields */ }
Expand description

The Text widget is a single-line text entry widget.

Text is the common implementation of single-line text editing that is shared between Entry, PasswordEntry, SpinButton, and other widgets. In all of these, Text is used as the delegate for the Editable implementation.

A fairly large set of key bindings are supported by default. If the entered text is longer than the allocation of the widget, the widget will scroll so that the cursor position is visible.

When using an entry for passwords and other sensitive information, it can be put into “password mode” using set_visibility(). In this mode, entered text is displayed using a “invisible” character. By default, GTK picks the best invisible character that is available in the current font, but it can be changed with set_invisible_char().

If you are looking to add icons or progress display in an entry, look at Entry. There other alternatives for more specialized use cases, such as SearchEntry.

If you need multi-line editable text, look at TextView.

§CSS nodes

text[.read-only]
├── placeholder
├── undershoot.left
├── undershoot.right
├── [selection]
├── [block-cursor]
╰── [window.popup]

Text has a main node with the name text. Depending on the properties of the widget, the .read-only style class may appear.

When the entry has a selection, it adds a subnode with the name selection.

When the entry is in overwrite mode, it adds a subnode with the name block-cursor that determines how the block cursor is drawn.

The CSS node for a context menu is added as a subnode with the name popup.

The undershoot nodes are used to draw the underflow indication when content is scrolled out of view. These nodes get the .left or .right style class added depending on where the indication is drawn.

When touch is used and touch selection handles are shown, they are using CSS nodes with name cursor-handle. They get the .top or .bottom style class depending on where they are shown in relation to the selection. If there is just a single handle for the text cursor, it gets the style class .insertion-cursor.

§Accessibility

Text uses the AccessibleRole::None role, which causes it to be skipped for accessibility. This is because Text is expected to be used as a delegate for a Editable implementation that will be represented to accessibility.

§Signals

§activate

Emitted when the user hits the Enter key.

The default bindings for this signal are all forms of the Enter key.

Action

§backspace

Emitted when the user asks for it.

This is a keybinding signal.

The default bindings for this signal are Backspace and Shift+Backspace.

Action

§copy-clipboard

Emitted to copy the selection to the clipboard.

This is a keybinding signal.

The default bindings for this signal are Ctrl+c and Ctrl+Insert.

Action

§cut-clipboard

Emitted to cut the selection to the clipboard.

This is a keybinding signal.

The default bindings for this signal are Ctrl+x and Shift+Delete.

Action

§delete-from-cursor

Emitted when the user initiates a text deletion.

This is a keybinding signal.

If the @type_ is DeleteType::Chars, GTK deletes the selection if there is one, otherwise it deletes the requested number of characters.

The default bindings for this signal are Delete for deleting a character and Ctrl+Delete for deleting a word.

Action

§insert-at-cursor

Emitted when the user initiates the insertion of a fixed string at the cursor.

This is a keybinding signal.

This signal has no default bindings.

Action

§insert-emoji

Emitted to present the Emoji chooser for the widget.

This is a keybinding signal.

The default bindings for this signal are Ctrl+. and Ctrl+;

Action

§move-cursor

Emitted when the user initiates a cursor movement.

If the cursor is not visible in @self_, this signal causes the viewport to be moved instead.

This is a keybinding signal.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.

The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without it does not. There are too many key combinations to list them all here.

  • , , , move by individual characters/lines
  • Ctrl+, etc. move by words/paragraphs
  • Home and End move to the ends of the buffer

Action

§paste-clipboard

Emitted to paste the contents of the clipboard.

This is a keybinding signal.

The default bindings for this signal are Ctrl+v and Shift+Insert.

Action

§preedit-changed

Emitted when the preedit text changes.

If an input method is used, the typed text will not immediately be committed to the buffer. So if you are interested in the text, connect to this signal.

Action

§toggle-overwrite

Emitted to toggle the overwrite mode of the Text.

This is a keybinding signal.

The default bindings for this signal is Insert.

Action

Widget

§destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§direction-changed

Emitted when the text direction of a widget changes.

§hide

Emitted when @widget is hidden.

§keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

§map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

§show

Emitted when @widget is shown.

§state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

§unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

Editable

§changed

Emitted at the end of a single user-visible operation on the contents.

E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

§delete-text

Emitted when text is deleted from the widget by the user.

The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely.

The @start_pos and @end_pos parameters are interpreted as for EditableExt::delete_text().

§insert-text

Emitted when text is inserted into the widget by the user.

The default handler for this signal will normally be responsible for inserting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the inserted text, or prevent it from being inserted entirely.

Retrieves whether the text in @self is visible.

§Returns

true if the text is currently visible

source

pub fn grab_focus_without_selecting(&self) -> bool

Causes @self to have keyboard focus.

It behaves like WidgetExt::grab_focus(), except that it doesn’t select the contents of @self. You only want to call this on some special entries which the user usually doesn’t want to replace all text in, such as search-as-you-type entries.

§Returns

true if focus is now inside @self

source

pub fn set_activates_default(&self, activates: bool)

If @activates is true, pressing Enter will activate the default widget for the window containing @self.

This usually means that the dialog containing the Text will be closed, since the default widget is usually one of the dialog buttons.

source

pub fn set_attributes(&self, attrs: Option<&AttrList>)

Sets attributes that are applied to the text.

§attrs

This can be used by on-screen keyboards and other input methods to adjust their behaviour.

§purpose

the purpose

source

pub fn set_invisible_char(&self, ch: char)

Sets the character to use when in “password mode”.

By default, GTK picks the best invisible char available in the current font. If you set the invisible char to 0, then the user will get no feedback at all; there will be no text on the screen as they type.

§ch

a Unicode character

source

pub fn set_max_length(&self, length: i32)

Sets the maximum allowed length of the contents of the widget.

If the current contents are longer than the given length, then they will be truncated to fit.

This is equivalent to getting @self’s EntryBuffer and calling EntryBufferExtManual::set_max_length() on it.

§length

the maximum length of the Text, or 0 for no maximum. (other than the maximum length of entries.) The value passed in will be clamped to the range 0-65536.

true to truncate multi-line text

source

pub fn set_visibility(&self, visible: bool)

Sets whether the contents of the Text are visible or not.

When visibility is set to false, characters are displayed as the invisible char, and will also appear that way when the text in the widget is copied to the clipboard.

By default, GTK picks the best invisible character available in the current font, but it can be changed with set_invisible_char().

Note that you probably want to set input-purpose to InputPurpose::Password or InputPurpose::Pin to inform input methods about the purpose of this self, in addition to setting visibility to false.

§visible

true if the contents of the Text are displayed as plaintext

source

pub fn unset_invisible_char(&self)

Unsets the invisible char.

After calling this, the default invisible char is used again.

source

pub fn im_module(&self) -> Option<GString>

pub fn connect_insert_emoji<F: Fn(&Text) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted to present the Emoji chooser for the widget.

This is a keybinding signal.

The default bindings for this signal are Ctrl+. and Ctrl+;

source

pub fn connect_move_cursor<F: Fn(&Text, MovementStep, i32, bool) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted when the user initiates a cursor movement.

If the cursor is not visible in @self_, this signal causes the viewport to be moved instead.

This is a keybinding signal.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.

The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without it does not. There are too many key combinations to list them all here.

  • , , , move by individual characters/lines
  • Ctrl+, etc. move by words/paragraphs
  • Home and End move to the ends of the buffer
§step

the granularity of the move, as a MovementStep

§count

the number of @step units to move

§extend

true if the move should extend the selection

source

pub fn connect_paste_clipboard<F: Fn(&Text) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted to paste the contents of the clipboard.

This is a keybinding signal.

The default bindings for this signal are Ctrl+v and Shift+Insert.

source

source

pub fn connect_preedit_changed<F: Fn(&Text, &str) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted when the preedit text changes.

If an input method is used, the typed text will not immediately be committed to the buffer. So if you are interested in the text, connect to this signal.

§preedit

the current preedit string

source

pub fn connect_toggle_overwrite<F: Fn(&Text) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted to toggle the overwrite mode of the Text.

This is a keybinding signal.

The default bindings for this signal is Insert.
