Text#

class Text(**properties: Any)#

Superclasses: Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, AccessibleText, Buildable, ConstraintTarget, Editable

A single-line text entry.

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

A large number of key bindings s 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 an “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 want to add icons or progress display in an entry, look at Entry. There are other alternatives for more specialized use cases, such as SearchEntry.

If you need multi-line editable text, use TextView.

Shortcuts and Gestures#

GtkText supports the following keyboard shortcuts:

Shift+:kbd:F10 or Menu opens the context menu.
Ctrl+:kbd:A or Ctrl+<kbd>wzxhzdk:0</kbd> selects all the text.
Ctrl+:kbd:Shift+:kbd:A or Ctrl+<kbd>wzxhzdk:1</kbd> unselects all.
Ctrl+:kbd:Z undoes the last modification.
Ctrl+:kbd:Y or Ctrl+:kbd:Shift+:kbd:Z redoes the last undone modification.
Ctrl+:kbd:Shift+:kbd:T toggles the text direction.
Clear clears the content.

Additionally, the following signals have default keybindings:

activate
backspace
copy_clipboard
cut_clipboard
delete_from_cursor
insert_emoji
move_cursor
paste_clipboard
toggle_overwrite

Actions#

GtkText defines a set of built-in actions:

clipboard.copy copies the contents to the clipboard.
clipboard.cut copies the contents to the clipboard and deletes it from the widget.
clipboard.paste inserts the contents of the clipboard into the widget.
menu.popup opens the context menu.
misc.insert-emoji opens the Emoji chooser.
misc.toggle-visibility toggles the GtkText:visibility property.
misc.toggle-direction toggles the text direction.
selection.delete deletes the current selection.
selection.select-all selects all of the widgets content.
text.redo redoes the last change to the contents.
text.undo undoes the last change to the contents.
text.clear removes all content.

CSS nodes#

text[.read-only]
├── placeholder
├── undershoot.left
├── undershoot.right
├── [selection]
├── [cursor-handle[.top]
├── [cursor-handle.bottom]
├── [block-cursor]
├── [cursor-handle[.top/.bottom][.insertion-cursor]]
╰── [window.popup]

GtkText 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#

GtkText uses the none role, which causes it to be skipped for accessibility. This is because GtkText is expected to be used as a delegate for a GtkEditable implementation that will be represented to accessibility.

Constructors#

class Text

classmethod new() → Widget#: Creates a new GtkText.

classmethod new_with_buffer(buffer: EntryBuffer) → Widget#

Creates a new GtkText with the specified buffer.

Parameters:: buffer – the buffer to use

Methods#

class Text

compute_cursor_extents(position: int) → tuple[Rect, Rect]#

Determines the positions of the strong and weak cursors for a given character position.

The position of each cursor is stored as a zero-width rectangle. The strong cursor location is the location where characters of the directionality equal to the base direction are inserted. The weak cursor location is the location where characters of the directionality opposite to the base direction are inserted.

The rectangle positions are in widget coordinates.

Added in version 4.4.

Parameters:: position – the character position

get_activates_default() → bool#

Returns whether pressing Enter will activate the default widget for the window containing the widget.

See set_activates_default.

get_attributes() → AttrList | None#

Gets the attribute list that was set on the text widget.

See set_attributes.

get_buffer() → EntryBuffer#: Get the entry buffer object which holds the text for this widget.

get_enable_emoji_completion() → bool#: Returns whether Emoji completion is enabled.

get_extra_menu() → MenuModel | None#

Gets the extra menu model of the text widget.

See set_extra_menu.

get_input_hints() → InputHints#: Gets the input hints of the text widget.

get_input_purpose() → InputPurpose#: Gets the input purpose of the text widget.

get_invisible_char() → str#

Retrieves the character displayed when visibility is set to false.

Note that GTK does not compute this value unless it needs it, so the value returned by this function is not very useful unless it has been explicitly set with set_invisible_char.

get_max_length() → int#

Retrieves the maximum allowed length of the contents.

See set_max_length.

This is equivalent to getting self's GtkEntryBuffer and calling get_max_length on it.

get_overwrite_mode() → bool#

Gets whether text is overwritten when typing.

See set_overwrite_mode.

get_placeholder_text() → str | None#

Retrieves the text that will be displayed when the text widget is empty and unfocused

See set_placeholder_text.

get_propagate_text_width() → bool#: Returns whether the text widget will grow and shrink with the content.

get_tabs() → TabArray | None#

Gets the tab stops for the text widget.

See set_tabs.

get_text_length() → int#

Retrieves the length of the contents.

This is equivalent to getting self's GtkEntryBuffer and calling get_length on it.

get_truncate_multiline() → bool#: Returns whether pasted text will be truncated to the first line.

get_visibility() → bool#: Retrieves whether the text is visible.

grab_focus_without_selecting() → bool#

Causes the text widget to have the keyboard focus.

It behaves like grab_focus, except that it does not 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.

set_activates_default(activates: bool) → None#

Sets whether pressing Enter will activate the default widget.

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

Parameters:: activates – true to activate window’s default widget on Enter keypress

set_attributes(attrs: AttrList | None = None) → None#

Apply attributes to the contents of the text widget.

Parameters:: attrs – a list of style attributes

set_buffer(buffer: EntryBuffer) → None#

Set the entry buffer object which holds the text for this widget.

Parameters:: buffer – an entry buffer object

set_enable_emoji_completion(enable_emoji_completion: bool) → None#

Sets whether Emoji completion is enabled.

If it is, typing ‘:’, followed by a recognized keyword, will pop up a window with suggested Emojis matching the keyword.

Parameters:: enable_emoji_completion – true to enable Emoji completion

set_extra_menu(model: MenuModel | None = None) → None#

Sets a menu model to add to the context menu of the text widget.

Parameters:: model – a menu model

set_input_hints(hints: InputHints) → None#

Sets hints that allow input methods to fine-tune their behaviour.

Parameters:: hints – input hints

set_input_purpose(purpose: InputPurpose) → None#

Sets the input purpose of the text widget.

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

Parameters:: purpose – the input purpose

set_invisible_char(ch: str) → None#

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.

Parameters:: ch – a Unicode character

set_max_length(length: int) → None#

Sets the maximum allowed length of the contents.

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

This is equivalent to getting self's GtkEntryBuffer and calling set_max_length on it.

Parameters:: 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

set_overwrite_mode(overwrite: bool) → None#

Sets whether the text is overwritten when typing.

Parameters:: overwrite – new value

set_placeholder_text(text: str | None = None) → None#

Sets the text to be displayed when the text widget is empty and unfocused.

This can be used to give a visual hint of the expected contents of the text widget.

Parameters:: text – a string to be displayed when self is empty and unfocused

set_propagate_text_width(propagate_text_width: bool) → None#

Sets whether the text widget should grow and shrink with the content.

Parameters:: propagate_text_width – true to propagate the text width

set_tabs(tabs: TabArray | None = None) → None#

Sets tab stops for the text widget.

Parameters:: tabs – tab stops

set_truncate_multiline(truncate_multiline: bool) → None#

Sets whether pasted text should be truncated to the first line.

Parameters:: truncate_multiline – true to truncate multi-line text

set_visibility(visible: bool) → None#

Sets whether the contents of the text widget are visible or not.

When visibility is set to false, characters are displayed as the invisible char, and it 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 password or pin to inform input methods about the purpose of this widget, in addition to setting visibility to false.

Parameters:: visible – true if the contents of the text widget are displayed as plain text

unset_invisible_char() → None#

Unsets the invisible char.

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

Properties#

class Text

props.activates_default: bool#: Whether to activate the default widget when Enter is pressed.

props.attributes: AttrList#

A list of Pango attributes to apply to the text.

This is mainly useful to change the size or weight of the text.

The PangoAttribute's start_index and end_index must refer to the GtkEntryBuffer text, i.e. without the preedit string.

props.buffer: EntryBuffer#: The GtkEntryBuffer object which stores the text.

props.enable_emoji_completion: bool#: Whether to suggest Emoji replacements.

props.extra_menu: MenuModel#: A menu model whose contents will be appended to the context menu.

props.im_module: str#

Which input method module should be used.

See IMMulticontext.

Setting this to a non-NULL value overrides the system-wide input method. See the gtk_im_module setting.

props.input_hints: InputHints#: Additional hints that allow input methods to fine-tune their behaviour.

props.input_purpose: InputPurpose#

The purpose of this text field.

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

Note that setting the purpose to password or pin is independent from setting visibility.

props.invisible_char: int#: The character to used when masking contents (in “password mode”).

props.invisible_char_set: bool#: Whether the invisible char has been set.

props.max_length: int#

Maximum number of characters that are allowed.

Zero indicates no limit.

props.overwrite_mode: bool#: If text is overwritten when typing.

props.placeholder_text: str#: The text that will be displayed in the GtkText when it is empty and unfocused.

props.propagate_text_width: bool#: Whether the widget should grow and shrink with the content.

props.scroll_offset: int#: Number of pixels scrolled of the screen to the left.

props.tabs: TabArray#: Custom tabs for this text widget.

props.truncate_multiline: bool#: When true, pasted multi-line text is truncated to the first line.

props.visibility: bool#: If false, the text is masked with the “invisible char”.
