Component

AtkComponent should be implemented by most if not all UI elements with an actual on-screen presence, i.e. components which can be said to have a screen-coordinate bounding box. Virtually all widgets will need to have AtkComponent implementations provided for their corresponding AtkObject class. In short, only UI elements which are *not* GUI elements will omit this ATK interface.

A possible exception might be textual information with a transparent background, in which case text glyph bounding box information is provided by AtkText.

Functions

addFocusHandler uint addFocusHandler(AtkFocusHandler handler): Warning atk_component_add_focus_handler is deprecated and should not be used in newly-written code. This method is deprecated since ATK version 2.9.4. If you need to track when an object gains or lose the focus, use state-changed:focused notification instead. Add the specified handler to the set of functions to be called when this object receives focus events (in or out). If the handler is already added it is not added again
addOnBoundsChanged void addOnBoundsChanged(void delegate(AtkRectangle*, Component) dlg, ConnectFlags connectFlags): The 'bounds-changed" signal is emitted when the bposition or size of the component changes.
contains int contains(int x, int y, AtkCoordType coordType): Checks whether the specified point is within the extent of the component.
getAlpha double getAlpha(): Returns the alpha value (i.e. the opacity) for this component, on a scale from 0 (fully transparent) to 1.0 (fully opaque). Since 1.12 Signal Details The "bounds-changed" signal void user_function (AtkComponent *atkcomponent, AtkRectangle *arg1, gpointer user_data) : Run Last The 'bounds-changed" signal is emitted when the bposition or size of the component changes.
getComponentStruct AtkComponent* getComponentStruct(): Get the main Gtk struct
getExtents void getExtents(int x, int y, int width, int height, AtkCoordType coordType): Gets the rectangle which gives the extent of the component.
getLayer AtkLayer getLayer(): Gets the layer of the component.
getMdiZorder int getMdiZorder(): Gets the zorder of the component. The value G_MININT will be returned if the layer of the component is not ATK_LAYER_MDI or ATK_LAYER_WINDOW.
getPosition void getPosition(int x, int y, AtkCoordType coordType): Gets the position of component in the form of a point specifying component's top-left corner.
getSize void getSize(int width, int height): Gets the size of the component in terms of width and height.
getStruct void* getStruct(): the main Gtk struct as a void*
grabFocus int grabFocus(): Grabs focus for this component.
refAccessibleAtPoint ObjectAtk refAccessibleAtPoint(int x, int y, AtkCoordType coordType): Gets a reference to the accessible child, if one exists, at the coordinate point specified by x and y.
removeFocusHandler void removeFocusHandler(uint handlerId): Warning atk_component_remove_focus_handler is deprecated and should not be used in newly-written code. This method is deprecated since ATK version 2.9.4. If you need to track when an object gains or lose the focus, use state-changed:focused notification instead. Remove the handler specified by handler_id from the list of functions to be executed when this object receives focus events (in or out).
setExtents int setExtents(int x, int y, int width, int height, AtkCoordType coordType): Sets the extents of component.
setPosition int setPosition(int x, int y, AtkCoordType coordType): Sets the postition of component.
setSize int setSize(int width, int height): Set the size of the component in terms of width and height.
