Gtk::TextView::TextView ( )

Gtk::TextView::TextView ( const Glib::RefPtr<TextBuffer>& buffer ) [explicit]

Member Function Documentation

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.

void Gtk::TextView::add_child_in_window	(	Widget&	child,
		TextWindowType	which_window,
		int	xpos,
		int	ypos
	)

Adds a child at fixed coordinates in one of the text widget's windows.

The window must have nonzero size (see set_border_window_size()). Note that the child coordinates are given relative to the Gdk::Window in question, and that these coordinates have no sane relationship to scrolling. When placing a child in Gtk::TEXT_WINDOW_WIDGET, scrolling is irrelevant, the child floats above all scrollable areas. But when placing a child in one of the scrollable windows (border windows or text window), you'll need to compute the child's correct position in buffer coordinates any time scrolling occurs or buffer changes occur, and then call move_child() to update the child's position. Unfortunately there's no good way to detect that scrolling has occurred, using the current API; a possible hack would be to update all child positions when the scroll adjustments change or the text buffer changes. See bug 64518 on bugzilla.gnome.org for status of fixing this issue.

Parameters:

	child	A Gtk::Widget.
	which_window	Which window the child should appear in.
	xpos	X position of child in window coordinates.
	ypos	Y position of child in window coordinates.

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.

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

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

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.

void Gtk::TextView::buffer_to_window_coords	(	TextWindowType	win,
		int	buffer_x,
		int	buffer_y,
		int &	window_x,
		int &	window_y
	)			const

Converts coordinate ( buffer_x, buffer_y) to coordinates for the window win, and stores the result in ( window_x, window_y).

Note that you can't convert coordinates for a nonexisting window (see set_border_window_size()).

Parameters:

	win	A Gtk::TextWindowType except Gtk::TEXT_WINDOW_PRIVATE.
	buffer_x	Buffer x coordinate.
	buffer_y	Buffer y coordinate.
	window_x	Window x coordinate return location.
	window_y	Window y coordinate return location.

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

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.

Parameters:

iter

A Gtk::TextIter.

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

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

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

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.

void Gtk::TextView::get_iter_at_location	(	TextBuffer::iterator&	iter,
		int	x,
		int	y
	)			const

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 window_to_buffer_coords().

Parameters:

	)			const

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 window_to_buffer_coords().

Note that this is different from get_iter_at_location(), which returns cursor locations, i.e. positions between characters.

Since gtkmm 2.6:

Parameters:

	iter	A Gtk::TextIter.
	trailing	Location to store an integer indicating where in the grapheme the user clicked. It will either be zero, or the number of characters in the grapheme. 0 represents the trailing edge of the grapheme.

void Gtk::TextView::get_iter_location	(	const TextBuffer::iterator&	iter,
		Gdk::Rectangle&	location
	)			const

Gets a rectangle which roughly contains the character at iter.

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.
	location	Bounds of the character at iter.

Justification Gtk::TextView::get_justification ( ) const

Parameters:

	target_iter	A Gtk::TextIter.
	y	A y coordinate.
	line_top	Return location for top coordinate of the line.

void Gtk::TextView::get_line_yrange	(	const TextBuffer::iterator&	iter,
		int &	y,
		int &	height
	)			const

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 buffer_to_window_coords().

bool Gtk::TextView::move_visually	(	TextBuffer::iterator&	iter,
		int	count
	)

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.

Parameters:

	iter	A Gtk::TextIter.
	count	Number of characters to move (negative moves left, positive moves right).

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