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.

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.

void Gtk::TextView::set_border_window_size | ( | TextWindowType | type, | |
int | size | |||
) |
Sets the width of Gtk::TEXT_WINDOW_LEFT or Gtk::TEXT_WINDOW_RIGHT, or the height of Gtk::TEXT_WINDOW_TOP or Gtk::TEXT_WINDOW_BOTTOM.
Automatically destroys the corresponding window if the size is set to 0, and creates the window if the size is set to non-zero. This function can only be used for the "border windows," it doesn't work with Gtk::TEXT_WINDOW_WIDGET, Gtk::TEXT_WINDOW_TEXT, or Gtk::TEXT_WINDOW_PRIVATE.
type | Window to affect. | |
size | Width or height of the window. |
void Gtk::TextView::set_buffer | ( | const Glib::RefPtr<TextBuffer>& | buffer | ) |
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.
buffer | A Gtk::TextBuffer. |
void Gtk::TextView::set_cursor_visible | ( | bool | setting = true |
) |
Toggles whether the insertion point is displayed.
A buffer with no editable text probably shouldn't have a visible cursor, so you may want to turn the cursor off.
setting | Whether to show the insertion cursor. |
void Gtk::TextView::set_editable | ( | bool | setting = true |
) |
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.

Tags in the buffer may override the default.
indent | Indentation in pixels. |

Sets the default left margin for text in text_view .
Tags in the buffer may override the default.
left_margin | Left margin in pixels. |
void Gtk::TextView::set_overwrite | ( | bool | overwrite = true |
) |
Changes the Gtk::TextView overwrite mode.
overwrite | true to turn on overwrite mode, false to turn it off. |

void Gtk::TextView::set_pixels_inside_wrap | ( | int | pixels_inside_wrap | ) |
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.
pixels_inside_wrap | Default number of pixels between wrapped lines. |

bool Gtk::TextView::starts_display_line | ( | const TextBuffer::iterator& | iter | ) |
Determines whether iter is at the start of a display line.
See forward_display_line() for an explanation of display lines vs. paragraphs.
iter | A Gtk::TextIter. |
true
if iter begins a wrapped line. void Gtk::TextView::window_to_buffer_coords | ( | TextWindowType | win, | |

int & | buffer_x, | |||
int & | buffer_y | |||

Converts coordinates on the window identified by win to buffer coordinates, storing the result in ( buffer_x , buffer_y ).
Note that you can't convert coordinates for a nonexisting window (see set_border_window_size()).
