Container

Object Hierarchy:

Description:

Content:

Properties:

• public uint border_width { set; get; }
• public Widget child { set; }
• public ResizeMode resize_mode { set; get; }

Static methods:

• public static weak ParamSpec class_find_child_property (ObjectClass cclass, string property_name)
  Finds a child property of a container class by name.
• public static weak ParamSpec class_list_child_properties (ObjectClass cclass, uint n_properties)
  Returns all child properties of a container class.
• public static void install_child_property (uint property_id, ParamSpec pspec)
  Installs a child property on a container class.

Creation methods:

• protected Container ()

Methods:

• public void add_with_properties (Widget widget, ...)
  Adds widget to container, setting child properties at the same time. See gtk_container_add and child_set for more details.
• public void child_get (Widget child, ...)
  Gets the values of one or more child properties for child and container.
• public void child_get_property (Widget child, string property_name, Value value)
  Gets the value of a child property for child and container.
• public void child_get_valist (Widget child, string first_property_name, void* var_args)
  Gets the values of one or more child properties for child and container.
• public void child_set (Widget child, ...)
  Sets one or more child properties for child and container.
• public void child_set_property (Widget child, string property_name, Value value)
  Sets a child property for child and container.
• public void child_set_valist (Widget child, string first_property_name, void* var_args)
  Sets one or more child properties for child and container.
• public virtual Type child_type ()
  Returns the type of the children supported by the container.
• public virtual unowned string composite_name (Widget child)
• public virtual void forall (Callback callback)
  Invokes callback on each 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. Most applications should use foreach, rather than forall.
• public virtual void forall_internal (bool include_internal, Callback callback)
• public void foreach (Callback callback)
  Invokes callback on each non-internal child of container. See forall for details on what constitutes an "internal" child. Most applications should use foreach, rather than forall.
• public uint get_border_width ()
  Retrieves the border width of the container. See set_border_width.
• public virtual void get_child_property (Widget child, uint property_id, Value value, ParamSpec pspec)
• public List<weak Widget> get_children ()
  Returns the container's non-internal children. See forall for details on what constitutes an "internal" child.
• public bool get_focus_chain (out List<Widget> focusable_widgets)
  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.
• public weak Widget get_focus_child ()
  Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling get_focus.
• public weak Adjustment get_focus_hadjustment ()
  Retrieves the horizontal focus adjustment for the container. See set_focus_hadjustment.
• public weak Adjustment get_focus_vadjustment ()
  Retrieves the vertical focus adjustment for the container. See set_focus_vadjustment.
• public ResizeMode get_resize_mode ()
  Returns the resize mode for the container. See set_resize_mode.
• public void propagate_expose (Widget child, EventExpose event)
  When a container receives an expose event, it must send synthetic expose events to all children that don't have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives an expose event, calls propagate_expose once for each child, passing in the event the container received.
• public void resize_children ()
• public void set_border_width (uint border_width)
  Sets the border width of the container.
• public virtual void set_child_property (Widget child, uint property_id, Value value, ParamSpec pspec)
• public void set_focus_chain (List<Widget> focusable_widgets)
  Sets a focus chain, overriding the one computed automatically by GTK+.
• public void set_focus_hadjustment (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 get_hadjustment for a typical way of obtaining the adjustment and set_focus_vadjustment for setting the vertical adjustment.
• public void set_focus_vadjustment (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 get_vadjustment for a typical way of obtaining the adjustment and set_focus_hadjustment for setting the horizontal adjustment.
• public void set_reallocate_redraws (bool needs_redraws)
  Sets the reallocate_redraws flag of the container to the given value.
• public void set_resize_mode (ResizeMode resize_mode)
  Sets the resize mode for the container.
• public void unset_focus_chain ()
  Removes a focus chain explicitly set with set_focus_chain.

Signals:

• public virtual void add (Widget widget)
• public virtual void check_resize ()
• public virtual void remove (Widget widget)
• public virtual void set_focus_child (Widget? widget)

Fields:

• public weak Widget focus_child
• public uint has_focus_chain
• public uint need_resize
• public uint reallocate_redraws
