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? 
  1.  objects[OID_WINDOW] = IIntuition->NewObject(WindowClass, NULL,
  2.   	WA_ScreenTitle, "Editor",
  3.   	WA_Title, "Editor",
  4.   	WA_DragBar, TRUE,
  5.   	WA_Activate, TRUE,
  6.   	WA_SizeGadget, TRUE,
  7.   	WA_CloseGadget, TRUE,
  8.   	WA_IDCMP, IDCMP_INTUITICKS,
  9.   	WINDOW_Position, WPOS_CENTERSCREEN,
  10.   	WINDOW_Layout, objects[OID_ROOT_LAYOUT]= IIntuition->NewObject(LayoutClass,NULL,
  11.   		LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
  12.   		LAYOUT_SpaceOuter, TRUE,
  13.   		LAYOUT_AddChild, objects[OID_VIRTUAL]=IIntuition->NewObject(VirtualClass,NULL,
  14.   			VIRTUALA_Contents, objects[OID_LAYOUT1] = IIntuition->NewObject(LayoutClass,NULL,
  15.   				LAYOUT_AddImage, objects[OID_BITMAP2]= IIntuition->NewObject(BitMapClass,NULL,	
  16.   						BITMAP_BitMap, BMCLASS_bm,
  17.   						BITMAP_Width, BitmapWidth,
  18.             			BITMAP_Height,BitmapHeight,
  19.             			BITMAP_Masking , TRUE,
  20.             			BITMAP_HasAlpha, TRUE,
  21.             		TAG_END),// end Bitmap
  22.   				TAG_END),// end layout

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. Simon

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.
