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_child_in_window()

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 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) it will move with the scrolling as needed.

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.

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.

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.

buffer_to_window_coords()

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 or nullptr.
window_y	Window y coordinate return location or nullptr.

forward_display_line()

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.

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.

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.

)

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.

Returns

A Gtk::TextBuffer.

get_buffer() [2/2]

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

get_cursor_locations()

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

Given an iter within a text layout, determine the positions of the strong and weak cursors if the insertion point is at that iterator.

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.

Since gtkmm 3.0:

Parameters

iter	A Gtk::TextIter.
strong	Location to store the strong cursor position (may be nullptr).
weak	Location to store the weak cursor position (may be nullptr).

const

Obtains a copy of the default text attributes.

These are the attributes used for text unless a tag overrides them. You'd typically pass the default attributes in to Gtk::TextIter::get_attributes() in order to get the attributes in effect at a given text position.

Returns

A new Gtk::TextAttributes.

get_editable()

bool Gtk::TextView::get_editable

(

)

const

Returns the default editability of the Gtk::TextView.

GdkEventKey *

gdk_event

)

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_im_context_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.

[C example ellipted]

Since gtkmm 2.22:

void Gtk::TextView::scroll_to	(	const Glib::RefPtr< TextBuffer::Mark > &	mark,
		double	within_margin,
		double	xalign,
		double	yalign
	)

Scrolls the TextView so that iter 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.

scroll_to() [2/4]

void Gtk::TextView::scroll_to	(	const Glib::RefPtr< TextBuffer::Mark > &	mark,

	)

Scrolls text_view so that mark is on the screen, by scrolling 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.

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.

scroll_to() [3/4]

bool Gtk::TextView::scroll_to	(	TextBuffer::iterator &	iter,
		double	within_margin,
		double	xalign,
		double	yalign
	)

Scrolls the TextView so that iter 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.

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.
