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_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.

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.

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).

Parameters

win	A Gtk::TextWindowType.
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`.

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

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

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.

Parameters

iter	A Gtk::TextIter.

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

bool Gtk::TextView::get_accepts_tab ( ) const

set_accepts_tab().

Returns: true if pressing the Tab key inserts a tab character, false if pressing the Tab key moves the keyboard focus.

int Gtk::TextView::get_bottom_margin ( ) const

Gets the bottom margin for text in the text_view.

Since gtkmm 3.20:

Returns: Bottom margin in pixels.

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

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.

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

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.

void Gtk::TextView::get_cursor_locations	(	const TextBuffer::const_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.

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`).

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]

Parameters

event The key event.

Returns: true if the input method handled the key event.

bool Gtk::TextView::move_mark_onscreen ( const Glib::RefPtr< TextBuffer::Mark >& mark )

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

Parameters

mark	A Gtk::TextMark.

Returns: true if the mark moved (wasn’t already onscreen).

void Gtk::TextView::move_overlay	(	Widget&	child,
		int	xpos,

	)

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.

void Gtk::TextView::reset_cursor_blink ( )

Ensures that the cursor is shown (i.e. not in an 'off' blink interval) and 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).

bool Gtk::TextView::scroll_to	(	TextBuffer::iterator&	iter,
		double	within_margin = `0`
	)

Scrolls the TextView so that iter 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.

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.

Returns: true if scrolling occurred.

		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.
