HRESULT | locationInParent ([out] long *x,[out, retval] long *y) |
Returns the location of the upper left corner of the object's bounding box relative to the immediate parent object. | |
HRESULT | foreground ([out, retval] IA2Color *foreground) |
Returns the foreground color of this object. | |
HRESULT | background ([out, retval] IA2Color *background) |
Returns the background color of this object. |
This interface provides the standard mechanism for an assistive technology to retrieve information concerning the graphical representation of an object. Coordinates used by the functions of this interface are specified in different coordinate systems. Their scale is the same and is equal to that of the screen coordinate system. In other words all coordinates are measured in pixels. They differ in their respective origin:
HRESULT IAccessibleComponent::background | ( | [out, retval] IA2Color * | background | ) | [get] |
Returns the background color of this object.
[out] | background | The returned color is the background color of this object or, if that is not supported, the default background color. |
S_OK |
HRESULT IAccessibleComponent::foreground | ( | [out, retval] IA2Color * | foreground | ) | [get] |
Returns the foreground color of this object.
[out] | foreground | The returned color is the foreground color of this object or, if that is not supported, the default foreground color. |
S_OK |
HRESULT IAccessibleComponent::locationInParent | ( | [out] long * | x, | |
[out, retval] long * | y | |||
) | [get] |
Returns the location of the upper left corner of the object's bounding box relative to the immediate parent object.
The coordinates of the bounding box are given relative to the parent's coordinate system. The coordinates of the returned position are relative to this object's parent or relative to the screen on which this object is rendered if it has no parent. If the object is not on any screen the returned position is (0,0).
