SPI_LAYER_INVALID | The layer cannot be determined or is somehow undefined. |
SPI_LAYER_BACKGROUND | Component belongs to the destop background. |
SPI_LAYER_CANVAS | Component is a canvas backdrop or drawing area. |
SPI_LAYER_WIDGET | Component is a 'normal' widget. |
SPI_LAYER_MDI | Component is drawn in the MDI layer and may have valid Z-information relative to other MDI-layer components. |
SPI_LAYER_POPUP | Component is in the popup layer, above other widgets and MDI components. |
SPI_LAYER_OVERLAY | Component is in the overlay plane - this value is reserved for future use. |
SPI_LAYER_WINDOW | Component is in the window layer and have valid Z-information relative to other window-layer components. |
SPI_LAYER_LAST_DEFINED | Used to determine the last valid value in the enum, should not be encountered. |
void AccessibleComponent_ref (AccessibleComponent *obj); |
Increment the reference count for an AccessibleComponent.
obj : | a pointer to an object implementing AccessibleComponent on which to operate. |
void AccessibleComponent_unref (AccessibleComponent *obj); |
Decrement the reference count for an AccessibleComponent.
obj : | a pointer to the object implementing AccessibleComponent on which to operate. |
SPIBoolean AccessibleComponent_contains (AccessibleComponent *obj, long int x, long int y, AccessibleCoordType ctype); |
Query whether a given AccessibleComponent contains a particular point.
obj : | a pointer to the AccessibleComponent to query. |
x : | a long specifying the x coordinate in question. |
y : | a long specifying the y coordinate in question. |
ctype : | the desired coordinate system of the point (x, y) (e.g. CSPI_COORD_TYPE_WINDOW, CSPI_COORD_TYPE_SCREEN). |
Returns : | a TRUE if the specified component contains the point (x, y), otherwise FALSE. |
Accessible* AccessibleComponent_getAccessibleAtPoint (AccessibleComponent *obj, long int x, long int y, AccessibleCoordType ctype); |
Get the accessible child at a given coordinate within an AccessibleComponent.
obj : | a pointer to the AccessibleComponent to query. |
x : | a long specifying the x coordinate of the point in question. |
y : | a long specifying the y coordinate of the point in question. |
ctype : | the coordinate system of the point (x, y) (e.g. CSPI_COORD_TYPE_WINDOW, CSPI_COORD_TYPE_SCREEN). |
Returns : | a pointer to an Accessible child of the specified component which contains the point (x, y), or NULL of no child contains the point. |
void AccessibleComponent_getExtents (AccessibleComponent *obj, long int *x, long int *y, long int *width, long int *height, AccessibleCoordType ctype); |
Get the bounding box of the specified AccessibleComponent.
obj : | a pointer to the AccessibleComponent to query. |
x : | a pointer to a long into which the minimum x coordinate will be returned. |
y : | a pointer to a long into which the minimum y coordinate will be returned. |
width : | a pointer to a long into which the x extents (width) will be returned. |
height : | a pointer to a long into which the y extents (height) will be returned. |
ctype : | the desired coordinate system into which to return the results, (e.g. CSPI_COORD_TYPE_WINDOW, CSPI_COORD_TYPE_SCREEN). |
void AccessibleComponent_getPosition (AccessibleComponent *obj, long int *x, long int *y, AccessibleCoordType ctype); |
Get the minimum x and y coordinates of the specified AccessibleComponent.
obj : | a pointer to the AccessibleComponent to query. |
x : | a pointer to a long into which the minimum x coordinate will be returned. |
y : | a pointer to a long into which the minimum y coordinate will be returned. |
ctype : | the desired coordinate system into which to return the results, (e.g. CSPI_COORD_TYPE_WINDOW, CSPI_COORD_TYPE_SCREEN). |
void AccessibleComponent_getSize (AccessibleComponent *obj, long int *width, long int *height); |
Get the size of the specified AccessibleComponent.
obj : | a pointer to the AccessibleComponent to query. |
width : | a pointer to a long into which the x extents (width) will be returned. |
height : | a pointer to a long into which the y extents (height) will be returned. |
AccessibleComponentLayer AccessibleComponent_getLayer (AccessibleComponent *obj); |
Query which layer the component is painted into, to help determine its visibility in terms of stacking order.
obj : | a pointer to the AccessibleComponent to query. |
Returns : | the AccessibleComponentLayer into which this component is painted. |
short AccessibleComponent_getMDIZOrder (AccessibleComponent *obj); |
Query the z stacking order of a component which is in the MDI or window layer. (Bigger z-order numbers mean nearer the top)
obj : | a pointer to the AccessibleComponent to query. |
Returns : | a short integer indicating the stacking order of the component in the MDI layer, or -1 if the component is not in the MDI layer. |
