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

|[ 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.

Constructors

this this(GtkTextView* gtkTextView, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Creates a new gtk.TextView If you don’t call TextView.setBuffer before using the text view, an empty default buffer will be created for you. Get the buffer with TextView.getBuffer. If you want to specify your own buffer, consider TextView.newWithBuffer.
this this(TextBuffer buffer): Creates a new gtk.TextView widget displaying the buffer buffer. One buffer can be shared among many widgets. buffer may be NULL to create a default buffer, in which case this function is equivalent to TextView.new. The text view adds its own reference count to the buffer; it does not take over an existing reference.

backwardDisplayLine bool backwardDisplayLine(TextIter 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
backwardDisplayLineStart bool backwardDisplayLineStart(TextIter 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
bufferToWindowCoords void bufferToWindowCoords(GtkTextWindowType win, int bufferX, int bufferY, int windowX, int windowY): Converts coordinate (buffer_x, buffer_y) to coordinates for the window win, and stores the result in (window_x, window_y).
forwardDisplayLine bool forwardDisplayLine(TextIter 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
forwardDisplayLineEnd bool forwardDisplayLineEnd(TextIter 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. 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
getAcceptsTab bool getAcceptsTab(): Returns whether pressing the Tab key inserts a tab characters. TextView.setAcceptsTab.
getBorderWindowSize int getBorderWindowSize(GtkTextWindowType type): Gets the width of the specified border window. See TextView.setBorderWindowSize.
getBottomMargin int getBottomMargin(): Gets the bottom margin for text in the text_view.
getBuffer TextBuffer getBuffer(): 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.
getCursorLocations void getCursorLocations(TextIter iter, GdkRectangle strong, GdkRectangle weak): 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.
getCursorVisible bool getCursorVisible(): Find out whether the cursor should be displayed.
getDefaultAttributes TextAttributes getDefaultAttributes(): 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 TextIter.getAttributes in order to get the attributes in effect at a given text position.
getEditable bool getEditable(): Returns the default editability of the gtk.TextView Tags in the buffer may override this setting for some ranges of text.
getIndent int getIndent(): Gets the default indentation of paragraphs in text_view. Tags in the view’s buffer may override the default. The indentation may be negative.
getInputHints GtkInputHints getInputHints(): Gets the value of the input-hints property.
getInputPurpose GtkInputPurpose getInputPurpose(): Gets the value of the input-purpose property.
getIterAtLocation bool getIterAtLocation(TextIter iter, int x, int y): 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 TextView.windowToBufferCoords.
getIterAtPosition bool getIterAtPosition(TextIter iter, int trailing, int x, int y): Retrieves the iterator pointing to the character 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 TextView.windowToBufferCoords.
getIterLocation void getIterLocation(TextIter iter, GdkRectangle location): Gets a rectangle which roughly contains the character at iter. The rectangle position is in buffer coordinates; use TextView.bufferToWindowCoords to convert these coordinates to coordinates for one of the windows in the text view.
getJustification GtkJustification getJustification(): Gets the default justification of paragraphs in text_view. Tags in the buffer may override the default.
getLeftMargin int getLeftMargin(): Gets the default left margin size of paragraphs in the text_view. Tags in the buffer may override the default.
getLineAtY void getLineAtY(TextIter targetIter, int y, int lineTop): Gets the gtk.TextIter at the start of the line containing the coordinate y. y is in buffer coordinates, convert from window coordinates with TextView.windowToBufferCoords. If non-NULL, line_top will be filled with the coordinate of the top edge of the line.
getLineTextAt string getLineTextAt(int y): Get the text line at the pixel y
getLineYrange void getLineYrange(TextIter iter, int y, int 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 TextView.bufferToWindowCoords.
getMonospace bool getMonospace(): Gets the value of the monospace property.
getOverwrite bool getOverwrite(): Returns whether the gtk.TextView is in overwrite mode or not.
getPixelsAboveLines int getPixelsAboveLines(): Gets the default number of pixels to put above paragraphs. Adding this function with TextView.getPixelsBelowLines is equal to the line space between each paragraph.
getPixelsBelowLines int getPixelsBelowLines(): Gets the value set by TextView.setPixelsBelowLines.
getPixelsInsideWrap int getPixelsInsideWrap(): Gets the value set by TextView.setPixelsInsideWrap.
getRightMargin int getRightMargin(): Gets the default right margin for text in text_view. Tags in the buffer may override the default.
getStruct void* getStruct(): the main Gtk struct as a void*
getTabs PgTabArray getTabs(): Gets the default tabs for text_view. Tags in the buffer may override the defaults. The returned array will be NULL if “standard” (8-space) tabs are used. Free the return value with pango_tab_array_free().
getTextViewStruct GtkTextView* getTextViewStruct(bool transferOwnership): Get the main Gtk struct
getTopMargin int getTopMargin(): Gets the top margin for text in the text_view.
getVisibleRect void getVisibleRect(GdkRectangle visibleRect): Fills visible_rect with the currently-visible region of the buffer, in buffer coordinates. Convert to window coordinates with TextView.bufferToWindowCoords.
getWindow Window getWindow(GtkTextWindowType win): Retrieves the gdk.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 NULL and nonexistent if their width or height is 0, and are nonexistent before the widget has been realized.
getWindowType GtkTextWindowType getWindowType(Window window): Usually used to find out which window an event corresponds to.
getWrapMode GtkWrapMode getWrapMode(): Gets the line wrapping for the view.
imContextFilterKeypress bool imContextFilterKeypress(GdkEventKey* 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().
insertText void insertText(string text): Simply appends some on the cursor position
moveChild void moveChild(Widget child, int xpos, int ypos): Updates the position of a child, as for TextView.addChildInWindow.
moveMarkOnscreen bool moveMarkOnscreen(TextMark mark): Moves a mark within the buffer so that it's located within the currently-visible text area.
moveVisually bool moveVisually(TextIter iter, int count): 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.
placeCursorOnscreen bool placeCursorOnscreen(): Moves the cursor to the currently visible region of the buffer, it it isn’t there already.
resetCursorBlink void resetCursorBlink(): 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).
resetImContext void resetImContext(): Reset the input method context of the text view if needed.
scrollMarkOnscreen void scrollMarkOnscreen(TextMark mark): Scrolls text_view the minimum distance such that mark is contained within the visible area of the widget.
scrollToIter bool scrollToIter(TextIter iter, double withinMargin, bool useAlign, double xalign, double yalign): Scrolls text_view 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 use_align 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 within_margin.
scrollToMark void scrollToMark(TextMark mark, double withinMargin, bool useAlign, double xalign, double yalign): Scrolls text_view 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 use_align 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 within_margin.
setAcceptsTab void setAcceptsTab(bool acceptsTab): 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.
setBorderWindowSize void setBorderWindowSize(GtkTextWindowType 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”, and it won’t work with GTK_TEXT_WINDOW_WIDGET, GTK_TEXT_WINDOW_TEXT, or GTK_TEXT_WINDOW_PRIVATE.
setBottomMargin void setBottomMargin(int bottomMargin): Sets the bottom margin for text in text_view.
setBuffer void setBuffer(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.
setCursorVisible void setCursorVisible(bool setting): 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.
setEditable void setEditable(bool setting): 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.
setIndent void setIndent(int indent): Sets the default indentation for paragraphs in text_view. Tags in the buffer may override the default.
setInputHints void setInputHints(GtkInputHints hints): Sets the input-hints property, which allows input methods to fine-tune their behaviour.
setInputPurpose void setInputPurpose(GtkInputPurpose purpose): Sets the input-purpose property which can be used by on-screen keyboards and other input methods to adjust their behaviour.
setJustification void setJustification(GtkJustification justification): Sets the default justification of text in text_view. Tags in the view’s buffer may override the default.
setLeftMargin void setLeftMargin(int leftMargin): Sets the default left margin for text in text_view. Tags in the buffer may override the default.
setMonospace void setMonospace(bool monospace): Sets the monospace property, which indicates that the text view should use monospace fonts.
setOverwrite void setOverwrite(bool overwrite): Changes the gtk.TextView overwrite mode.
setPixelsAboveLines void setPixelsAboveLines(int pixelsAboveLines): Sets the default number of blank pixels above paragraphs in text_view. Tags in the buffer for text_view may override the defaults.
setPixelsBelowLines void setPixelsBelowLines(int pixelsBelowLines): Sets the default number of pixels of blank space to put below paragraphs in text_view. May be overridden by tags applied to text_view’s buffer.
setPixelsInsideWrap void setPixelsInsideWrap(int pixelsInsideWrap): 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.
setRightMargin void setRightMargin(int rightMargin): Sets the default right margin for text in the text view. Tags in the buffer may override the default.
setTabs void setTabs(PgTabArray tabs): Sets the default tab stops for paragraphs in text_view. Tags in the buffer may override the default.
setTopMargin void setTopMargin(int topMargin): Sets the top margin for text in text_view.
setWrapMode void setWrapMode(GtkWrapMode wrapMode): Sets the line wrapping for the view.
startsDisplayLine bool startsDisplayLine(TextIter iter): Determines whether iter is at the start of a display line. See TextView.forwardDisplayLine for an explanation of display lines vs. paragraphs.

Static functions

getType GType getType()

Variables

gtkTextView GtkTextView* gtkTextView;: the main Gtk struct

Inherited Members

From Container

gtkContainer GtkContainer* gtkContainer;: the main Gtk struct
getContainerStruct GtkContainer* getContainerStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
removeAll void removeAll(): Removes all widgets from the container
getType GType getType()
add void add(Widget widget): Adds widget to container. Typically used for simple containers such as gtk.Window, gtk.Frame, or gtk.Button; for more complicated layout containers such as gtk.Box or gtk.Grid, this function will pick default packing parameters that may not be correct. So consider functions such as Box.packStart and Grid.attach as an alternative to Container.add in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.
checkResize void checkResize()
childGetProperty void childGetProperty(Widget child, string propertyName, Value value): Gets the value of a child property for child and container.
childGetValist void childGetValist(Widget child, string firstPropertyName, void* varArgs): Gets the values of one or more child properties for child and container.
childNotify void childNotify(Widget child, string childProperty): Emits a child-notify signal for the [child property][child-properties] child_property on the child.
childNotifyByPspec void childNotifyByPspec(Widget child, ParamSpec pspec): Emits a child-notify signal for the [child property][child-properties] specified by pspec on the child.
childSetProperty void childSetProperty(Widget child, string propertyName, Value value): Sets a child property for child and container.
childSetValist void childSetValist(Widget child, string firstPropertyName, void* varArgs): Sets one or more child properties for child and container.
childType GType childType(): Returns the type of the children supported by the container.
forall void forall(GtkCallback callback, void* callbackData): Invokes callback on each direct child of container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.
foreach_ void foreach_(GtkCallback callback, void* callbackData): Invokes callback on each non-internal child of container. See Container.forall for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.
getBorderWidth uint getBorderWidth(): Retrieves the border width of the container. See Container.setBorderWidth.
getChildren ListG getChildren(): Returns the container’s non-internal children. See Container.forall for details on what constitutes an "internal" child.
getFocusChain bool getFocusChain(ListG focusableWidgets): Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable_widgets and returns FALSE.
getFocusChild Widget getFocusChild(): Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling Window.getFocus.
getFocusHadjustment Adjustment getFocusHadjustment(): Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().
getFocusVadjustment Adjustment getFocusVadjustment(): Retrieves the vertical focus adjustment for the container. See Container.setFocusVadjustment.
getPathForChild WidgetPath getPathForChild(Widget child): Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.
getResizeMode GtkResizeMode getResizeMode(): Returns the resize mode for the container. See gtk_container_set_resize_mode ().
propagateDraw void propagateDraw(Widget child, Context cr): When a container receives a call to the draw function, it must send synthetic draw calls to all children that don’t have their own gdk.Windows This function provides a convenient way of doing this. A container, when it receives a call to its draw function, calls Container.propagateDraw once for each child, passing in the cr the container received.
remove void remove(Widget widget): Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use widget again it’s usually more efficient to simply destroy it directly using Widget.destroy since this will remove it from the container and help break any circular reference count cycles.
resizeChildren void resizeChildren()
setBorderWidth void setBorderWidth(uint borderWidth): Sets the border width of the container.
setFocusChain void setFocusChain(ListG focusableWidgets): Sets a focus chain, overriding the one computed automatically by GTK+.
setFocusChild void setFocusChild(Widget child): Sets, or unsets if child is NULL, the focused child of container.
setFocusHadjustment void setFocusHadjustment(Adjustment adjustment): Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See ScrolledWindow.getHadjustment for a typical way of obtaining the adjustment and Container.setFocusVadjustment for setting the vertical adjustment.
setFocusVadjustment void setFocusVadjustment(Adjustment adjustment): Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See ScrolledWindow.getVadjustment for a typical way of obtaining the adjustment and Container.setFocusHadjustment for setting the horizontal adjustment.
setReallocateRedraws void setReallocateRedraws(bool needsRedraws): Sets the reallocate_redraws flag of the container to the given value.
setResizeMode void setResizeMode(GtkResizeMode resizeMode): Sets the resize mode for the container.
unsetFocusChain void unsetFocusChain(): Removes a focus chain explicitly set with Container.setFocusChain.
