GI.Gtk.Objects.TextView

You may wish to begin by reading the [text widget conceptual overview][TextWidget] which gives an overview of all the objects and data types related to the text widget and how they work together.

CSS nodes

plain code

textview.view
├── border.top
├── border.left
├── text
│   ╰── [selection]
├── border.right
├── border.bottom
╰── [window.popup]

GtkTextView has a main css node with name textview and style class .view, and subnodes for each of the border windows, and the main text area, with names border and text, respectively. The border nodes each get one of the style classes .left, .right, .top or .bottom.

A node representing the selection will appear below the text node.

If a context menu is opened, the window node will appear as a subnode of the main node.

Methods

addChildAtAnchor

textViewAddChildAtAnchor

Arguments

:: (HasCallStack, MonadIO m, IsTextView a, IsWidget b, IsTextChildAnchor c)

=> a

textView: a TextView

-> b

child: a Widget

-> c

anchor: a TextChildAnchor in the TextBuffer for textView

-> m ()

Adds a child widget in the text buffer, at the given anchor.

addChildInWindow

textViewAddChildInWindow

Arguments

:: (HasCallStack, MonadIO m, IsTextView a, IsWidget b)

=> a

textView: a TextView

-> b

child: a Widget

-> TextWindowType

whichWindow: which window the child should appear in

-> Int32

xpos: X position of child in window coordinates

-> Int32

ypos: Y position of child in window coordinates

-> m ()

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

The window must have nonzero size (see textViewSetBorderWindowSize). 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.

backwardDisplayLine

textViewBackwardDisplayLine

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

-> m Bool

Returns: True if iter 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 TextBuffer.

backwardDisplayLineStart

textViewBackwardDisplayLineStart

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

-> m Bool

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

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 TextBuffer.

bufferToWindowCoords

textViewBufferToWindowCoords

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextWindowType

win: a TextWindowType, except TextWindowTypePrivate

-> Int32

bufferX: buffer x coordinate

-> Int32

bufferY: buffer y coordinate

-> m (Int32, Int32)

Converts coordinate (bufferX, bufferY) to coordinates for the window win, and stores the result in (windowX, windowY).

Note that you can’t convert coordinates for a nonexisting window (see textViewSetBorderWindowSize).

forwardDisplayLine

textViewForwardDisplayLine

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

-> m Bool

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

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 TextBuffer.

forwardDisplayLineEnd

textViewForwardDisplayLineEnd

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

Returns: True if iter 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 TextBuffer.

getBuffer

textViewGetBuffer

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> m TextBuffer

Returns: a TextBuffer

Returns the 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.

getCursorLocations

textViewGetCursorLocations

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Maybe TextIter

iter: a TextIter

-> m (Rectangle, Rectangle)

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 Nothing, 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 textViewBufferToWindowCoords to convert these coordinates to coordinates for one of the windows in the text view.

Since: 3.0

getCursorVisible

textViewGetCursorVisible

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

textViewGetDefaultAttributes

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> m TextAttributes

Returns: a new TextAttributes

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 textIterGetAttributes in order to get the attributes in effect at a given text position.

The return value is a copy owned by the caller of this function, and should be freed with textAttributesUnref.

getEditable

textViewGetEditable

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> m Bool

Returns: whether text is editable by default

Returns the default editability of the TextView. Tags in the buffer may override this setting for some ranges of text.

x: x position, in buffer coordinates

-> Int32

y: y position, in buffer coordinates

-> m (Bool, TextIter)

Returns: True if the position is over text

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 textViewWindowToBufferCoords.

getVisibleRect

textViewGetVisibleRect

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

Fills visibleRect with the currently-visible region of the buffer, in buffer coordinates. Convert to window coordinates with textViewBufferToWindowCoords.

getWindow

textViewGetWindow

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextWindowType

win: window to get

-> m (Maybe Window)

Returns: a Window, or Nothing

Retrieves the Window 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 Nothing and nonexistent if their width or height is 0, and are nonexistent before the widget has been realized.

getWindowType

textViewGetWindowType

Arguments

:: (HasCallStack, MonadIO m, IsTextView a, IsWindow b)

=> a

textView: a TextView

-> b

window: a window type

-> m TextWindowType

Returns: the window type.

Usually used to find out which window an event corresponds to.

If you connect to an event signal on textView, this function should be called on event->window to see which window it was.

getWrapMode

textViewGetWrapMode

=> a

textView: a TextView

-> m WrapMode

Returns: the line wrap setting

Gets the line wrapping for the view.

textViewImContextFilterKeypress

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> EventKey

event: the key event

-> m Bool

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

Allow the 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 iMContextFilterKeypress.

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 TextView.

C code

static gboolean
gtk_foo_bar_key_press_event (GtkWidget   *widget,
                             GdkEventKey *event)
{
  if ((key->keyval == GDK_KEY_Return || key->keyval == GDK_KEY_KP_Enter))
    {
      if (gtk_text_view_im_context_filter_keypress (GTK_TEXT_VIEW (view), event))
        return TRUE;
    }

    // Do some stuff

  return GTK_WIDGET_CLASS (gtk_foo_bar_parent_class)->key_press_event (widget, event);
}

Since: 2.22

moveChild

moveVisually

textViewMoveVisually

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

-> Int32

count: number of characters to move (negative moves left, positive moves right)

-> m Bool

Returns: True 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 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.

new

textViewNew

Arguments

:: (HasCallStack, MonadIO m)

=> m TextView

Returns: a new TextView

Creates a new TextView. If you don’t call textViewSetBuffer before using the text view, an empty default buffer will be created for you. Get the buffer with textViewGetBuffer. If you want to specify your own buffer, consider textViewNewWithBuffer.

newWithBuffer

textViewNewWithBuffer

Arguments

:: (HasCallStack, MonadIO m, IsTextBuffer a)

=> a

buffer: a TextBuffer

-> m TextView

Returns: a new TextView.

Creates a new TextView widget displaying the buffer buffer. One buffer can be shared among many widgets. buffer may be Nothing to create a default buffer, in which case this function is equivalent to textViewNew. The text view adds its own reference count to the buffer; it does not take over an existing reference.

placeCursorOnscreen

textViewPlaceCursorOnscreen

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> m Bool

Returns: True if the cursor had to be moved.

Moves the cursor to the currently visible region of the buffer, it it isn’t there already.

resetCursorBlink

textViewResetCursorBlink

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> m ()

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 Widget::key-press-event handler).

Since: 3.20

resetImContext

textViewResetImContext

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> m ()

Reset the input method context of the text view if needed.

This can be necessary in the case where modifying the buffer would confuse on-going input method behavior.

Since: 2.22

scrollMarkOnscreen

textViewScrollMarkOnscreen

Arguments

:: (HasCallStack, MonadIO m, IsTextView a, IsTextMark b)

=> a

textView: a TextView

-> b

mark: a mark in the buffer for textView

-> m ()

Scrolls textView the minimum distance such that mark is contained within the visible area of the widget.

scrollToIter

textViewScrollToIter

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

-> Double

withinMargin: margin as a [0.0,0.5) fraction of screen size

-> Bool

useAlign: whether to use alignment arguments (if False, just get the mark onscreen)

-> Double

xalign: horizontal alignment of mark within visible area

-> Double

yalign: vertical alignment of mark within visible area

-> m Bool

Returns: True if scrolling occurred

Scrolls textView so that iter is on the screen in the position indicated by xalign and yalign. An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If useAlign is False, 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 withinMargin.

Note that this function uses the currently-computed height of the lines in the text buffer. 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 textViewScrollToMark which saves a point to be scrolled to after line validation.

scrollToMark

textViewScrollToMark

Arguments

:: (HasCallStack, MonadIO m, IsTextView a, IsTextMark b)

=> a

textView: a TextView

-> b

mark: a TextMark

withinMargin: margin as a [0.0,0.5) fraction of screen size

-> Bool

useAlign: whether to use alignment arguments (if False, just get the mark onscreen)

-> Double

xalign: horizontal alignment of mark within visible area

-> Double

yalign: vertical alignment of mark within visible area

-> m ()

Scrolls textView so that mark is on the screen in the position indicated by xalign and yalign. An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If useAlign is False, 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 withinMargin.

setAcceptsTab

textViewSetAcceptsTab

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: A TextView

-> Bool

acceptsTab: True if pressing the Tab key should insert a tab character, False, if pressing the Tab key should move the keyboard focus.

-> m ()

Sets the behavior of the text widget when the Tab key is pressed. If acceptsTab is True, a tab character is inserted. If acceptsTab is False the keyboard focus is moved to the next widget in the focus chain.

Since: 2.4

-> TextWindowType

type: window to affect

-> Int32

size: width or height of the window

-> m ()

Sets the width of TextWindowTypeLeft or TextWindowTypeRight, or the height of TextWindowTypeTop or TextWindowTypeBottom. 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”, and it won’t work with TextWindowTypeWidget, TextWindowTypeText, or TextWindowTypePrivate.

setBottomMargin

textViewSetBottomMargin

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Int32

bottomMargin: bottom margin in pixels

Arguments

:: (HasCallStack, MonadIO m, IsTextView a, IsTextBuffer b)

=> a

textView: a TextView

-> Maybe b

buffer: a TextBuffer

-> m ()

Sets buffer as the buffer being displayed by textView. 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; TextView will not “adopt” it.

setCursorVisible

textViewSetCursorVisible

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Bool

setting: whether to show the insertion cursor

-> m ()

Toggles whether the insertion point should be displayed. A buffer with no editable text probably shouldn’t have a visible cursor, so you may want to turn the cursor off.

Note that this property may be overridden by the Settings:gtk-keynave-use-caret settings.

setEditable

textViewSetEditable

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

setPixelsBelowLines

textViewSetPixelsBelowLines

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Int32

pixelsBelowLines: pixels below paragraphs

-> m ()

Sets the default number of pixels of blank space to put below paragraphs in textView. May be overridden by tags applied to textView’s buffer.

setPixelsInsideWrap

textViewSetPixelsInsideWrap

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Int32

pixelsInsideWrap: default number of pixels between wrapped lines

-> m ()

Sets the default number of pixels of blank space to leave between display/wrapped lines within a paragraph. May be overridden by tags in textView’s buffer.

setRightMargin

textViewSetRightMargin

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Int32

rightMargin: right margin in pixels

-> m ()

Sets the default right margin for text in the text view. Tags in the buffer may override the default.

Note that this function is confusingly named. In CSS terms, the value set here is padding.

setTabs

textViewSetTabs

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TabArray

tabs: tabs as a TabArray

-> m ()

Sets the default tab stops for paragraphs in textView. Tags in the buffer may override the default.

setTopMargin

textViewSetTopMargin

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> Int32

topMargin: top margin in pixels

-> m ()

Sets the top margin for text in textView.

Note that this function is confusingly named. In CSS terms, the value set here is padding.

Since: 3.18

setWrapMode

textViewSetWrapMode

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> WrapMode

wrapMode: a WrapMode

-> m ()

Sets the line wrapping for the view.

startsDisplayLine

textViewStartsDisplayLine

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextIter

iter: a TextIter

-> m Bool

Returns: True if iter begins a wrapped line

Determines whether iter is at the start of a display line. See textViewForwardDisplayLine for an explanation of display lines vs. paragraphs.

windowToBufferCoords

textViewWindowToBufferCoords

Arguments

:: (HasCallStack, MonadIO m, IsTextView a)

=> a

textView: a TextView

-> TextWindowType

win: a TextWindowType except TextWindowTypePrivate

-> Int32

windowX: window x coordinate

-> Int32

windowY: window y coordinate

-> m (Int32, Int32)

Converts coordinates on the window identified by win to buffer coordinates, storing the result in (bufferX,bufferY).

Note that you can’t convert coordinates for a nonexisting window (see textViewSetBorderWindowSize).
