Properties

align_set: boolean
alignment: Pango.Alignment

Specifies how to align the lines of text with respect to each other.

Note that this property describes how to align the lines of text in case there are several of them. The "xalign" property of #GtkCellRenderer, on the other hand, sets the horizontal alignment of the whole text.

attributes: Pango.AttrList
background: string
background_gdk: Gdk.Color

Background color as a #GdkColor

background_rgba: Gdk.RGBA

Background color as a #GdkRGBA

background_set: boolean
cell_background: string
cell_background_gdk: Gdk.Color

Cell background as a #GdkColor

cell_background_rgba: Gdk.RGBA

Cell background as a #GdkRGBA

cell_background_set: boolean
data_handler: Gda.DataHandler
editable: boolean
editable_set: boolean
editing: boolean
ellipsize: EllipsizeMode

Specifies the preferred place to ellipsize the string, if the cell renderer does not have enough room to display the entire string. Setting it to %PANGO_ELLIPSIZE_NONE turns off ellipsizing. See the wrap-width property for another way of making the text fit into a given width.

ellipsize_set: boolean
family: string
family_set: boolean
font: string
font_desc: FontDescription
foreground: string
foreground_gdk: Gdk.Color

Foreground color as a #GdkColor

foreground_rgba: Gdk.RGBA

Foreground color as a #GdkRGBA

foreground_set: boolean
g_type_instance: TypeInstance
height: number
is_expanded: boolean
is_expander: boolean
language: string
language_set: boolean
markup: string
max_width_chars: number

The desired maximum width of the cell, in characters. If this property is set to -1, the width will be calculated automatically.

For cell renderers that ellipsize or wrap text; this property controls the maximum reported width of the cell. The cell should not receive any greater allocation unless it is set to expand in its #GtkCellLayout and all of the cell's siblings have received their natural width.

options: string
parent_instance: InitiallyUnowned
placeholder_text: string

The text that will be displayed in the #GtkCellRenderer if #GtkCellRendererText:editable is %TRUE and the cell is empty.

Since 3.6

rise: number
rise_set: boolean
scale: number
scale_set: boolean
sensitive: boolean
single_paragraph_mode: boolean
size: number
size_points: number
size_set: boolean
stretch: Stretch
stretch_set: boolean
strikethrough: boolean
strikethrough_set: boolean
style: Pango.Style
style_set: boolean
text: string
to_be_deleted: boolean
type: GType<unknown>
underline: Underline
underline_set: boolean
value: object
variant: Pango.Variant
variant_set: boolean
visible: boolean
weight: number
weight_set: boolean
width: number
width_chars: number

The desired width of the cell, in characters. If this property is set to -1, the width will be calculated automatically, otherwise the cell will request either 3 characters or the property value, whichever is greater.

wrap_mode: Pango.WrapMode

Specifies how to break the string into multiple lines, if the cell renderer does not have enough room to display the entire string. This property has no effect unless the wrap-width property is set.

wrap_width: number

Specifies the minimum width at which the text is wrapped. The wrap-mode property can be used to influence at what character positions the line breaks can be placed. Setting wrap-width to -1 turns wrapping off.

xalign: number
xpad: number
yalign: number
ypad: number
name: string

Methods

  • Passes an activate event to the cell renderer for possible processing. Some cell renderers may use events; for example, #GtkCellRendererToggle toggles when it gets a mouse click.

    Parameters

    • event: Gdk.Event

      a #GdkEvent

    • widget: Gtk.Widget

      widget that received the event

    • path: string

      widget-dependent string representation of the event location; e.g. for #GtkTreeView, a string representation of #GtkTreePath

    • background_area: Gdk.Rectangle

      background area as passed to gtk_cell_renderer_render()

    • cell_area: Gdk.Rectangle

      cell area as passed to gtk_cell_renderer_render()

    • flags: Gtk.CellRendererState

      render flags

    Returns boolean

  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transform_to: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transform_from: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • force_floating(): void
  • This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • freeze_notify(): void
  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • get_alignment(): [number, number]
  • get_data(key?: string): object
  • get_fixed_size(): [number, number]
  • get_padding(): [number, number]
  • get_preferred_height(widget: Gtk.Widget): [number, number]
  • get_preferred_height_for_width(widget: Gtk.Widget, width: number): [number, number]
  • get_preferred_width(widget: Gtk.Widget): [number, number]
  • get_preferred_width_for_height(widget: Gtk.Widget, height: number): [number, number]
  • get_property(property_name?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

    Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

    Parameters

    • Optional property_name: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • get_qdata(quark: number): object
  • get_sensitive(): boolean
  • Obtains the width and height needed to render the cell. Used by view widgets to determine the appropriate size for the cell_area passed to gtk_cell_renderer_render(). If cell_area is not %NULL, fills in the x and y offsets (if set) of the cell relative to this location.

    Please note that the values set in width and height, as well as those in x_offset and y_offset are inclusive of the xpad and ypad properties.

    Parameters

    • widget: Gtk.Widget

      the widget the renderer is rendering to

    • cell_area: Gdk.Rectangle

      The area a cell will be allocated, or %NULL

    Returns [number, number, number, number]

  • get_visible(): boolean
  • getv(names: string[], values: any[]): void
  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • is_activatable(): boolean
  • is_floating(): boolean
  • notify(property_name: string): void
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • property_name: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns void

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • Invokes the virtual render function of the #GtkCellRenderer. The three passed-in rectangles are areas in cr. Most renderers will draw within cell_area; the xalign, yalign, xpad, and ypad fields of the #GtkCellRenderer should be honored with respect to cell_area. background_area includes the blank space around the cell, and also the area containing the tree expander; so the background_area rectangles for all cells tile to cover the entire window.

    Parameters

    Returns void

  • run_dispose(): void
  • set_alignment(xalign: number, yalign: number): void
  • set_data(key: string, data?: object): void
  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • set_fixed_height_from_font(number_of_rows: number): void
  • Sets the height of a renderer to explicitly be determined by the “font” and “y_pad” property set on it. Further changes in these properties do not affect the height, so they must be accompanied by a subsequent call to this function. Using this function is unflexible, and should really only be used if calculating the size of a cell is too slow (ie, a massive number of cells displayed). If number_of_rows is -1, then the fixed height is unset, and the height is determined by the properties again.

    Parameters

    • number_of_rows: number

      Number of rows of text each cell renderer is allocated, or -1

    Returns void

  • set_fixed_size(width: number, height: number): void
  • set_padding(xpad: number, ypad: number): void
  • set_property(property_name: string, value?: any): void
  • set_sensitive(sensitive: boolean): void
  • set_visible(visible: boolean): void
  • Starts editing the contents of this cell, through a new #GtkCellEditable widget created by the #GtkCellRendererClass.start_editing virtual function.

    Parameters

    • event: Gdk.Event

      a #GdkEvent

    • widget: Gtk.Widget

      widget that received the event

    • path: string

      widget-dependent string representation of the event location; e.g. for #GtkTreeView, a string representation of #GtkTreePath

    • background_area: Gdk.Rectangle

      background area as passed to gtk_cell_renderer_render()

    • cell_area: Gdk.Rectangle

      cell area as passed to gtk_cell_renderer_render()

    • flags: Gtk.CellRendererState

      render flags

    Returns Gtk.CellEditable

  • steal_data(key?: string): object
  • steal_qdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • stop_editing(canceled: boolean): void
  • Informs the cell renderer that the editing is stopped. If canceled is %TRUE, the cell renderer will emit the #GtkCellRenderer::editing-canceled signal.

    This function should be called by cell renderer implementations in response to the #GtkCellEditable::editing-done signal of #GtkCellEditable.

    Parameters

    • canceled: boolean

      %TRUE if the editing has been canceled

    Returns void

  • thaw_notify(): void
  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • Passes an activate event to the cell renderer for possible processing. Some cell renderers may use events; for example, #GtkCellRendererToggle toggles when it gets a mouse click.

    virtual

    • cell_area: Gdk.Rectangle

      The area a cell will be allocated, or %NULL

    Returns [number, number, number, number]

  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

  • watch_closure(closure: TClosure<any, any>): void
  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compat_control(what: number, data: object): number
  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • g_iface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • property_name: string

      name of a property to look up.

    Returns ParamSpec

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of #GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • g_iface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • g_iface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Creates a new #GdauiDataCellRendererTextual. Adjust how text is drawn using object properties. Object properties can be set globally (with g_object_set()). Also, with #GtkTreeViewColumn, you can bind a property to a value in a #GtkTreeModel. For example, you can bind the "text" property on the cell renderer to a string value in the model, thus rendering a different string in each row of the #GtkTreeView

    Parameters

    • dh: Gda.DataHandler

      a #GdaDataHandler object, or %NULL

    • type: GType<unknown>

      the #GType being edited

    • options: string

      options as a string

    Returns Gdaui.DataCellRendererTextual

  • Creates a new #GtkCellRendererText. Adjust how text is drawn using object properties. Object properties can be set globally (with g_object_set()). Also, with #GtkTreeViewColumn, you can bind a property to a value in a #GtkTreeModel. For example, you can bind the “text” property on the cell renderer to a string value in the model, thus rendering a different string in each row of the #GtkTreeView

    Returns Gtk.CellRendererText

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • object_type: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
