So the default cursor is the "Arrow" cursor and the top-left of the arrow (where the point is) is the part that clicks or interacts with other controls. How can I change the pointing part to say the tail of the arrow?
What I have is a custom cursor (a bitmap image) which is a circle at 16x16 size and I want the very center of it to be the pointer. I have another custom arrow-like cursor that points downward-left also 16x16 and I want the bottom-left corner of the cursor to be the pointer. I think there's a property in the cursor class for this but I'm not sure what it's called.
This is actually specified in the CUR file format.
The CUR file format is an almost identical image file format for non-animated cursors in Microsoft Windows. The only differences between these two file formats are the bytes used to identify them and the addition of a hotspot in the CUR format header; the hotspot is defined as the pixel offset (in x,y coordinates) from the top-left corner of the cursor image where the user is actually pointing the mouse.
Programs that can edit CUR files generally allow you to specify the hot spot. More information can be found in this question.
