Member Function Documentation

◆ add_child_at_anchor()

void Gtk::TextView::add_child_at_anchor	(	Widget &	child,
		const Glib::RefPtr< TextBuffer::ChildAnchor > &	anchor
	)

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

Parameters

child	A `Gtk::Widget`.
anchor	A `Gtk::TextChildAnchor` in the `Gtk::TextBuffer` for text_view.

◆ add_overlay()

void Gtk::TextView::add_overlay	(	Widget &	child,
		int	xpos,
		int	ypos
	)

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

The xpos and ypos must be in buffer coordinates (see get_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.

Parameters

child	A `Gtk::Widget`.
xpos	X position of child in window coordinates.
ypos	Y position of child in window coordinates.

◆ backward_display_line()

bool Gtk::TextView::backward_display_line ( TextBuffer::iterator & iter )

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.

Parameters

iter	A `Gtk::TextIter`.

Returns: true if iter was moved and is not on the end iterator.

◆ backward_display_line_start()

bool Gtk::TextView::backward_display_line_start ( TextBuffer::iterator & iter )

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

Parameters

iter	A `Gtk::TextIter`.

Returns: true if iter was moved and is not on the end iterator.

◆ buffer_to_window_coords()

void Gtk::TextView::buffer_to_window_coords	(	TextWindowType	win,

		int &	window_y
	)		const

Converts buffer coordinates to window coordinates.

Parameters

win	A `Gtk::TextWindowType`.
buffer_x	Buffer x coordinate.

Parameters

iter	A `Gtk::TextIter`.

Returns: true if iter was moved and is not on the end iterator.

◆ forward_display_line_end()

bool Gtk::TextView::forward_display_line_end ( TextBuffer::iterator & iter )

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

Parameters

iter	A `Gtk::TextIter`.

Returns: true if iter was moved and is not on the end iterator.

◆ get_accepts_tab()

bool Gtk::TextView::get_accepts_tab ( ) const

◆ get_buffer() [1/2]

Glib::RefPtr< TextBuffer > Gtk::TextView::get_buffer ( )

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

Returns: A Gtk::TextBuffer.

◆ get_buffer() [2/2]

Glib::RefPtr< const TextBuffer > Gtk::TextView::get_buffer ( ) const

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

◆ get_cursor_locations() [1/2]

void Gtk::TextView::get_cursor_locations	(	const TextBuffer::const_iterator &	iter,
		Gdk::Rectangle &	strong,
		Gdk::Rectangle &	weak
	)		const

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 nullptr, 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 buffer_to_window_coords() to convert these coordinates to coordinates for one of the windows in the text view.

Parameters

iter	A `Gtk::TextIter`.
strong	Location to store the strong cursor position.
weak	Location to store the weak cursor position.

Scrolls the TextView so that mark is on the screen, in the position indicated by xalign and yalign, possibly not scrolling at all.

The effective screen for purposes of this function is reduced by a margin of size within_margin.

Parameters

mark	An mark pointing to the position that should be made visible by scrolling.
within_margin	margin as a [0.0,0.5] fraction of screen size.
xalign	horizontal alignment of mark within visible area. An alignment of 0.0 indicates left, 1.0 indicates right, 0.5 means center.
yalign	vertical alignment of mark within visible area. An alignment of 0.0 indicates top, 1.0 indicates bottom, 0.5 means center.

The effective screen for purposes of this function is reduced by a margin of size within_margin.

Note: This function uses the currently-computed height of the lines in the text buffer. Note that 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_text_view_scroll_to_mark() which saves a point to be scrolled to after line validation.

Parameters

iter	An iterator pointing to the position that should be made visible by scrolling.
within_margin	margin as a [0.0,0.5] fraction of screen size.
xalign	horizontal alignment of mark within visible area. An alignment of 0.0 indicates left, 1.0 indicates right, 0.5 means center.
yalign	vertical alignment of mark within visible area. An alignment of 0.0 indicates top, 1.0 indicates bottom, 0.5 means center.

Returns: true if scrolling occurred.
