Bitmap.image Coordinates

Hello,
i have a Bitmap.image inside a virtual.gadget.
If the user press LMB on the image, i want the coordinates.
Can someone tell me how I can get them?

 objects[OID_WINDOW] = IIntuition->NewObject(WindowClass, NULL,
  	WA_ScreenTitle, "Editor",
  	WA_Title, "Editor",
  	WA_DragBar, TRUE,
  	WA_Activate, TRUE,
  	WA_SizeGadget, TRUE,
  	WA_CloseGadget, TRUE,
  	WA_IDCMP, IDCMP_INTUITICKS,
  	WINDOW_Position, WPOS_CENTERSCREEN,
  	WINDOW_Layout, objects[OID_ROOT_LAYOUT]= IIntuition->NewObject(LayoutClass,NULL,
  		LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
  		LAYOUT_SpaceOuter, TRUE,
  		LAYOUT_AddChild, objects[OID_VIRTUAL]=IIntuition->NewObject(VirtualClass,NULL,
  			VIRTUALA_Contents, objects[OID_LAYOUT1] = IIntuition->NewObject(LayoutClass,NULL,
  				LAYOUT_AddImage, objects[OID_BITMAP2]= IIntuition->NewObject(BitMapClass,NULL,	
  						BITMAP_BitMap, BMCLASS_bm,
  						BITMAP_Width, BitmapWidth,
            			BITMAP_Height,BitmapHeight,
            			BITMAP_Masking , TRUE,
            			BITMAP_HasAlpha, TRUE,
            		TAG_END),// end Bitmap
  				TAG_END),// end layout
  			TAG_END), // end virtuallayout

Re: Bitmap.image Coordinates

Have you tried:
GetAttrs( objects[OID_ROOT_LAYOUT], GA_Left, &left, GA+Top, &top, TAG_DONE );

As the bitmap.image is the only thing in the layout, the coordinates of that gadget should be almost equal to the bitmap. You may have to adjust the left and top values for any layout spacing/borders etc.

Re: Bitmap.image Coordinates

Hello Simon,
there is more in the layout, not just the bitmap.image.
And the bitmap is larger then the virtual.gadget.
The first Problem I have is how to detect if the lmb was pressed inside the bitmap.image or virtual.gadget.
