ComponentIF

#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)

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*, ComponentIF) dlg, ConnectFlags connectFlags)

The 'bounds-changed" signal is emitted when the bposition or size of the component changes.

contains
bool 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).

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
bool 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)

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
bool setExtents(int x, int y, int width, int height, AtkCoordType coordType)

Sets the extents of @component.

setPosition
bool setPosition(int x, int y, AtkCoordType coordType)

Sets the postition of @component.

setSize
bool setSize(int width, int height)

Set the size of the @component in terms of width and height.

Properties

onBoundsChangedListeners
void delegate(AtkRectangle*, ComponentIF)[] onBoundsChangedListeners [@property getter]
Undocumented in source.
