Struct gtk4::TextView

source ·
#[repr(transparent)]
pub struct TextView { /* private fields */ }
Expand description

A widget that displays the contents of a TextBuffer.

An example GtkTextview

You may wish to begin by reading the conceptual overview, which gives an overview of all the objects and data types related to the text widget and how they work together.

CSS nodes

textview.view
├── border.top
├── border.left
├── text
│   ╰── [selection]
├── border.right
├── border.bottom
╰── [window.popup]

TextView has a main css node with name textview and style class .view, and subnodes for each of the border windows, and the main text area, with names border and text, respectively. The border nodes each get one of the style classes .left, .right, .top or .bottom.

A node representing the selection will appear below the text node.

If a context menu is opened, the window node will appear as a subnode of the main node.

Accessibility

TextView uses the AccessibleRole::TextBox role.

Properties

accepts-tab

Whether Tab will result in a tab character being entered.

Readable | Writeable

bottom-margin

The bottom margin for text in the text view.

Note that this property is confusingly named. In CSS terms, the value set here is padding, and it is applied in addition to the padding from the theme.

Don’t confuse this property with margin-bottom.

Readable | Writeable

Which IM (input method) module should be used for this text_view.

See IMMulticontext.

Setting this to a non-None value overrides the system-wide IM module setting. See the GtkSettings gtk-im-module property.

Readable | Writeable

indent

Amount to indent the paragraph, in pixels.

A negative value of indent will produce a hanging indentation. That is, the first line will have the full width, and subsequent lines will be indented by the absolute value of indent.

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

Readable | Writeable

justification

Readable | Writeable

left-margin

The default left margin for text in the text view.

Tags in the buffer may override the default.

Note that this property is confusingly named. In CSS terms, the value set here is padding, and it is applied in addition to the padding from the theme.

Signals

backspace

Gets emitted when the user asks for it.

The ::backspace signal is a keybinding signal.

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

Action

copy-clipboard

Gets emitted to copy the selection to the clipboard.

The ::copy-clipboard signal is a keybinding signal.

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

Action

cut-clipboard

Gets emitted to cut the selection to the clipboard.

The ::cut-clipboard signal is a keybinding signal.

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

Action

delete-from-cursor

Gets emitted when the user initiates a text deletion.

The ::delete-from-cursor signal 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, Ctrl+Delete for deleting a word and Ctrl+Backspace for deleting a word backwards.

Action

extend-selection

Emitted when the selection needs to be extended at @location.

insert-at-cursor

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

The ::insert-at-cursor signal is a keybinding signal.

This signal has no default bindings.

Action

insert-emoji

Gets emitted to present the Emoji chooser for the @text_view.

The ::insert-emoji signal is a keybinding signal.

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

Action

move-cursor

Gets emitted when the user initiates a cursor movement.

The ::move-cursor signal is a keybinding signal. If the cursor is not visible in @text_view, this signal causes the viewport to be moved instead.

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
  • PgUp and PgDn move vertically by pages
  • Ctrl+PgUp and Ctrl+PgDn move horizontally by pages

Action

move-viewport

Gets emitted to move the viewport.

The ::move-viewport signal is a keybinding signal, which can be bound to key combinations to allow the user to move the viewport, i.e. change what part of the text view is visible in a containing scrolled window.

There are no default bindings for this signal.

Action

paste-clipboard

Gets emitted to paste the contents of the clipboard into the text view.

The ::paste-clipboard signal is a keybinding signal.

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

Action

preedit-changed

Emitted when preedit text of the active IM 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.

This signal is only emitted if the text at the given position is actually editable.

Action

select-all

Gets emitted to select or unselect the complete contents of the text view.

The ::select-all signal is a keybinding signal.

The default bindings for this signal are Ctrl+a and Ctrl+/ for selecting and Shift+Ctrl+a and Ctrl+</kbd> for unselecting.

Action

set-anchor

Gets emitted when the user initiates settings the “anchor” mark.

The ::set-anchor signal is a keybinding signal which gets emitted when the user initiates setting the “anchor” mark. The “anchor” mark gets placed at the same position as the “insert” mark.

This signal has no default bindings.

Action

toggle-cursor-visible

Gets emitted to toggle the cursor-visible property.

The ::toggle-cursor-visible signal is a keybinding signal.

The default binding for this signal is F7.

Action

toggle-overwrite

Gets emitted to toggle the overwrite mode of the text view.

The ::toggle-overwrite signal is a keybinding signal.

The default binding 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).

Implementations§

source§

impl TextView

source

pub const NONE: Option<&'static TextView> = None

source

pub fn new() -> TextView

Creates a new TextView.

If you don’t call TextViewExt::set_buffer() before using the text view, an empty default buffer will be created for you. Get the buffer with TextViewExt::buffer(). If you want to specify your own buffer, consider with_buffer().

Returns

a new TextView

source

pub fn with_buffer(buffer: &impl IsA<TextBuffer>) -> TextView

Creates a new TextView widget displaying the buffer @buffer.

One buffer can be shared among many widgets. @buffer may be None to create a default buffer, in which case this function is equivalent to new(). The text view adds its own reference count to the buffer; it does not take over an existing reference.

buffer

a TextBuffer

Returns

a new TextView.

source

pub fn builder() -> TextViewBuilder

Creates a new builder-pattern struct instance to construct TextView objects.

This method returns an instance of TextViewBuilder which can be used to create TextView objects.
