Thanks: 1 times

in MFC(C++), v19.

I want to get the Mouse Position of the part where the image is displayed In LAnnotationWindow.

I implemented it using the GetBitmapVisibleRect () function, and I think I would just calculate the Scroll offset.

But I can not find a way to get the scroll offset.

How can I get that value?

It doesn't appear we have any methods for retrieving the current scroll positions on the LAnnotationWindow. However, you can use get around this by using the ScrollTo method, which returns the amount scrolled:


// Scroll back to origin
POINT offset = annWin.ScrollTo(0, 0);
// Invert scroll offset to get back to original
offset.x *= -1;
offset.y *= -1;
// Scroll back to original and save how far it actually scrolled
offset = annWin.ScrollTo((L_INT)offset.x, (L_INT)offset.y);
