gtk-sharp 2.10.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. Widget that displays a using System; using Gtk; class TextViewSample { static void Main () { new TextViewSample (); } TextViewSample () { Application.Init (); Window win = new Window ("TextViewSample"); win.DeleteEvent += new DeleteEventHandler (OnWinDelete); win.SetDefaultSize (600,400); Gtk.TextView view; Gtk.TextBuffer buffer; view = new Gtk.TextView (); buffer = view.Buffer; buffer.Text = "Hello, this is some text"; win.Add (view); win.ShowAll (); Application.Run (); } void OnWinDelete (object obj, DeleteEventArgs args) { Application.Quit (); } } Now you might put the view in a container and display it on the screen; when the user edits the text, events on the buffer will be emitted, such as , , and so on. Gtk.Container Method System.Void Converts specified buffer coordinates to coordinates for window a , except for x coordinate of the buffer y coordinate of the buffer return location for the window's x coordinate return location for the window's y coordinate Note that you can't convert coordinates for a nonexisting window (see . Method System.Int32 Gets the width of the specified border window. a window to return size from the width of the window Method System.Boolean Moves the given iter backward by one display (wrapped) line the given if was moved and is not on the end iterator 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 . Method Gdk.Window Retrieves the corresponding to an area of the text view window to get a , or Retrieves the corresponding to an area of the text view; possible windows include the overall widget window, child windows on the left, right, top, bottom, and the window that displays the text buffer. Windows are and nonexistent if their width or height is 0, and are nonexistent before the widget has been realized. Method System.Void Sets the width of or , or the height of or . the window to affect the width or height of the window 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 , , or . Method System.Boolean Moves the cursor to the currently visible region of the buffer if it isn't there already. if the cursor had to be moved Method System.Boolean Moves forward to the next display line end a if was moved and is not on the end iterator 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 . Method System.Void Adds a child widget in the text buffer, at the given anchor any a in the current Method System.Boolean Moves the given backward to the next display line start the given if was moved and is not on the end iterator 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 . Method System.Boolean Moves the given forward by one display (wrapped) line the given if was moved and is not on the end iterator 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 . Method System.Void Gets the y coordinate of the top of the line containing , and the height of the line the given return location for the y coordinate return location for the height 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 . Method System.Void Scrolls the view so that is on the screen in the position indicated by and a given margin of screen size, the valid range is 0.0 to 0.5 whether to use alignment arguments (if , just get the mark onscreen) horizontal alignment of mark within visible area vertical alignment of mark within visible area An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If is , the text scrolls 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 . Method System.Boolean Determines whether iter is at the start of a display line the given if begins a wrapped line Determines whether iter is at the start of a display line. See for an explanation of display lines vs. paragraphs. Method Gtk.TextWindowType Used for finding out which window an event corresponds to a window type the window type Method System.Boolean Move the iterator a given number of characters visually, treating it as the strong cursor position the given the number of characters to move (negative moves left, positive moves right) if iter moved and is not on the end iterator 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 bidirection 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. Method System.Boolean Moves within the buffer so that it's located within the currently-visible text area a if the mark moved (wasn't already onscreen) Method System.Boolean Scrolls the text view so that is on the screen in the position indicated by and the given margin of screen size, the valid range is 0.0 to 0.5 whether to use alignment arguments (if , just get the mark onscreen) horizontal alignment of mark within visible area vertical alignment of mark within visible area if scrolling occurred Scrolls the text view so that is on the screen in the position indicated by and . An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If is , the text scrolls 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 which saves a point to be scrolled to after line validation. Method System.Void Scrolls the text view the minimum distance such that is contained within the visible area of the widget a mark in the current Method System.Void Converts coordinates on the window to buffer coordinates a except x coordinate of the window y coordinate of the window return location for the buffer's x coordinate return location for the buffer's y coordinate Note that you can't convert coordinates for a nonexisting window (see . Constructor Internal constructor Pointer to the C object. This is an internal constructor, and should not be used by user code. Constructor Creates a new TextView If you don't set the before using the text view, an empty default buffer will be created for you. If you want to specify your own buffer, use . Constructor Creates a new TextView displaying a specified buffer. the buffer to be displayed Creates a new widget displaying the buffer. One buffer can be shared among many widgets. Property Gtk.TextAttributes The default text attributes a s Obtains a copy of the default text attributes. These are the attributes used for text unless a tag overrides them.

If non-, will be filled with the coordinate of the top edge of the line. Method System.Void Updates the position of a child child widget already added to the text view new X position in window coordinates new Y position in window coordinates Method System.Void Adds a child at fixed coordinates in one of the text widget's windows. a a a a The window must have non-zero size (see ). Note that the child coordinates are given relative to the 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 will need to compute the child's correct position in buffer coordinates any time scrolling occurs or buffer changes occur, and then call to update the child's position. Unfortunately there is 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.
