Creates a new Gtk::TextView.

If you don’t call Gtk::TextView#buffer= before using the text view, an empty default buffer will be created for you. Get the buffer with Gtk::TextView#buffer. If you want to specify your own buffer, consider Gtk::TextView#new_with_buffer.

Creates a new Gtk::TextView widget displaying the buffer @buffer.

One buffer can be shared among many widgets. @buffer may be nil to create a default buffer, in which case this function is equivalent to Gtk::TextView.new. The text view adds its own reference count to the buffer; it does not take over an existing reference.

Returns the type id (GType) registered in GLib type system.

Returns whether pressing the Tab key inserts a tab characters.

See Gtk::TextView#accepts_tab=.

Sets the behavior of the text widget when the Tab key is pressed.

If @accepts_tab is true, a tab character is inserted. If @accepts_tab is false the keyboard focus is moved to the next widget in the focus chain.

Adds a child widget in the text buffer, at the given @anchor.

Adds @child at a fixed coordinate in the Gtk::TextView's text window.

The @xpos and @ypos must be in buffer coordinates (see Gtk::TextView#iter_location to convert to buffer coordinates).

@child will scroll with the text view.

If instead you want a widget that will not move with the Gtk::TextView contents see Gtk::Overlay.

Moves the given @iter backward by one display (wrapped) line.

A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view’s width; paragraphs are the same in all views, since they depend on the contents of the Gtk::TextBuffer.

Moves the given @iter backward to the next display line start.

Gets the bottom margin for text in the @text_view.

Sets the bottom margin for text in @text_view.

Note that this function is confusingly named. In CSS terms, the value set here is padding.

Returns the Gtk::TextBuffer being displayed by this text view.

The reference count on the buffer is not incremented; the caller of this function won’t own a new reference.

Sets @buffer as the buffer being displayed by @text_view.

The previous buffer displayed by the text view is unreferenced, and a reference is added to @buffer. If you owned a reference to @buffer before passing it to this function, you must remove that reference yourself; Gtk::TextView will not “adopt” it.

Converts buffer coordinates to window coordinates.

Determine the positions of the strong and weak cursors if the insertion point is at @iter.

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 of the paragraph are inserted. The weak cursor location is the location where characters of the directionality opposite to the base direction of the paragraph are inserted.

If @iter is nil, the actual cursor position is used.

Note that if @iter happens to be the actual cursor position, and there is currently an IM preedit sequence being entered, the returned locations will be adjusted to account for the preedit cursor’s offset within the preedit sequence.

The rectangle position is in buffer coordinates; use Gtk::TextView#buffer_to_window_coords to convert these coordinates to coordinates for one of the windows in the text view.

Find out whether the cursor should be displayed.

Toggles whether the insertion point should be displayed.

A buffer with no editable text probably shouldn’t have a visible cursor, so you may want to turn the cursor off.

Note that this property may be overridden by the [property@Gtk::Settings:gtk-keynav-use-caret] setting.

Returns the default editability of the Gtk::TextView.

Tags in the buffer may override this setting for some ranges of text.

Sets the default editability of the Gtk::TextView.

You can override this default setting with tags in the buffer, using the “editable” attribute of tags.

Gets the menu model that gets added to the context menu or nil if none has been set.

Sets a menu model to add when constructing the context menu for @text_view.

You can pass nil to remove a previously set extra menu.

Moves the given @iter forward by one display (wrapped) line.

A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view’s width; paragraphs are the same in all views, since they depend on the contents of the Gtk::TextBuffer.

Moves the given @iter forward to the next display line end.

Gets a Gtk::Widget that has previously been set as gutter.

See Gtk::TextView#gutter=.

@win must be one of %GTK_TEXT_WINDOW_LEFT, %GTK_TEXT_WINDOW_RIGHT, %GTK_TEXT_WINDOW_TOP, or %GTK_TEXT_WINDOW_BOTTOM.

Allow the Gtk::TextView input method to internally handle key press and release events.

If this function returns true, then no further processing should be done for this key event. See Gtk::IMContext#filter_keypress.

Note that you are expected to call this function from your handler when overriding key event handling. This is needed in the case when you need to insert your own key handling between the input method and the default key event handling of the Gtk::TextView.

WARNING ⚠️ The following code is in c ⚠️

static gboolean
gtk_foo_bar_key_press_event (Gtk::Widget *widget,
                             Gdk::Event  *event)
{
  guint keyval;

  gdk_event_get_keyval ((Gdk::Event*)event, &keyval);

  if (keyval == GDK_KEY_Return || keyval == GDK_KEY_KP_Enter)
    {
      if (gtk_text_view_im_context_filter_keypress (GTK_TEXT_VIEW (widget), event))
        return TRUE;
    }

  // Do some stuff

  return GTK_WIDGET_CLASS (gtk_foo_bar_parent_class)->key_press_event (widget, event);
}

Gets the default indentation of paragraphs in @text_view.

Tags in the view’s buffer may override the default. The indentation may be negative.

Sets the default indentation for paragraphs in @text_view.

Tags in the buffer may override the default.

Gets the input-hints of the Gtk::TextView.

Sets the input-hints of the Gtk::TextView.

The input-hints allow input methods to fine-tune their behaviour.

Gets the input-purpose of the Gtk::TextView.

Sets the input-purpose of the Gtk::TextView.

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

Retrieves the iterator at buffer coordinates @x and @y.

Buffer coordinates are coordinates for the entire buffer, not just the currently-displayed portion. If you have coordinates from an event, you have to convert those to buffer coordinates with Gtk::TextView#window_to_buffer_coords.

Retrieves the iterator pointing to the character at buffer coordinates @x and @y.

Buffer coordinates are coordinates for the entire buffer, not just the currently-displayed portion. If you have coordinates from an event, you have to convert those to buffer coordinates with Gtk::TextView#window_to_buffer_coords.

Note that this is different from Gtk::TextView#iter_at_location, which returns cursor locations, i.e. positions between characters.

Gets a rectangle which roughly contains the character at @iter.

The rectangle position is in buffer coordinates; use Gtk::TextView#buffer_to_window_coords to convert these coordinates to coordinates for one of the windows in the text view.

Gets the default justification of paragraphs in @text_view.

Tags in the buffer may override the default.

Sets the default justification of text in @text_view.

Tags in the view’s buffer may override the default.

Gets the default left margin size of paragraphs in the @text_view.

Tags in the buffer may override the default.

Sets the default left margin for text in @text_view.

Tags in the buffer may override the default.

Note that this function is confusingly named. In CSS terms, the value set here is padding.

Gets the Gtk::TextIter at the start of the line containing the coordinate @y.

@y is in buffer coordinates, convert from window coordinates with Gtk::TextView#window_to_buffer_coords. If non-nil, @line_top will be filled with the coordinate of the top edge of the line.

Gets the y coordinate of the top of the line containing @iter, and the height of the line.

The coordinate is a buffer coordinate; convert to window coordinates with Gtk::TextView#buffer_to_window_coords.

Gets the Pango::Context that is used for rendering LTR directed text layouts.

The context may be replaced when CSS changes occur.

Gets whether the Gtk::TextView uses monospace styling.

Sets whether the Gtk::TextView should display text in monospace styling.

Moves a mark within the buffer so that it's located within the currently-visible text area.

Updates the position of a child.

See Gtk::TextView#add_overlay.

Move the iterator a given number of characters visually, treating it as the strong cursor position.

If @count is positive, then the new strong cursor position will be @count positions to the right of the old cursor position. If @count is negative then the new strong cursor position will be @count positions to the left of the old cursor position.

In the presence of bi-directional text, the correspondence between logical and visual order will depend on the direction of the current run, and there may be jumps when the cursor is moved off of the end of a run.

Returns whether the Gtk::TextView is in overwrite mode or not.

Changes the Gtk::TextView overwrite mode.

Gets the default number of pixels to put above paragraphs.

Adding this function with Gtk::TextView#pixels_below_lines is equal to the line space between each paragraph.

Sets the default number of blank pixels above paragraphs in @text_view.

Tags in the buffer for @text_view may override the defaults.

Gets the default number of pixels to put below paragraphs.

The line space is the sum of the value returned by this function and the value returned by Gtk::TextView#pixels_above_lines.

Sets the default number of pixels of blank space to put below paragraphs in @text_view.

May be overridden by tags applied to @text_view’s buffer.

Gets the default number of pixels to put between wrapped lines inside a paragraph.

Sets the default number of pixels of blank space to leave between display/wrapped lines within a paragraph.

May be overridden by tags in @text_view’s buffer.

Moves the cursor to the currently visible region of the buffer.

Removes a child widget from @text_view.

Ensures that the cursor is shown.

This also resets the time that it will stay blinking (or visible, in case blinking is disabled).

This function should be called in response to user input (e.g. from derived classes that override the textview's event handlers).

Reset the input method context of the text view if needed.

This can be necessary in the case where modifying the buffer would confuse on-going input method behavior.

Gets the default right margin for text in @text_view.

Tags in the buffer may override the default.

Sets the default right margin for text in the text view.

Tags in the buffer may override the default.

Note that this function is confusingly named. In CSS terms, the value set here is padding.

Gets the Pango::Context that is used for rendering RTL directed text layouts.

The context may be replaced when CSS changes occur.

Scrolls @text_view the minimum distance such that @mark is contained within the visible area of the widget.

Scrolls @text_view so that @iter is on the screen in the position indicated by @xalign and @yalign.

An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If @use_align is false, the text scrolls the minimal distance to get the mark onscreen, possibly not scrolling at all. The effective screen for purposes of this function is reduced by a margin of size @within_margin.

Note that this function uses the currently-computed height of the lines in the text buffer. Line heights are computed in an idle handler; so this function may not have the desired effect if it’s called before the height computations. To avoid oddness, consider using Gtk::TextView#scroll_to_mark which saves a point to be scrolled to after line validation.

Scrolls @text_view so that @mark is on the screen in the position indicated by @xalign and @yalign.

An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If @use_align is false, the text scrolls the minimal distance to get the mark onscreen, possibly not scrolling at all. The effective screen for purposes of this function is reduced by a margin of size @within_margin.

Places @widget into the gutter specified by @win.

@win must be one of %GTK_TEXT_WINDOW_LEFT, %GTK_TEXT_WINDOW_RIGHT, %GTK_TEXT_WINDOW_TOP, or %GTK_TEXT_WINDOW_BOTTOM.

Determines whether @iter is at the start of a display line.

See Gtk::TextView#forward_display_line for an explanation of display lines vs. paragraphs.

Gets the default tabs for @text_view.

Tags in the buffer may override the defaults. The returned array will be nil if “standard” (8-space) tabs are used. Free the return value with Pango::TabArray#free.

Sets the default tab stops for paragraphs in @text_view.

Tags in the buffer may override the default.

Gets the top margin for text in the @text_view.
