Variants

NoOp

LeftMouseButtonDown

LeftMouseButtonUp

Note: When double clicking, there will be two LeftMouseButtonUp events in short succession - first a LeftMouseButtonUp { is_double_click: false }, followed by a LeftMouseButtonUp { is_double_click: true }.

This was done for ease of implementation - it allows a target to ignore single clicks and handle double clicks (or vice versa), but it precludes an obvious way to have a target handle single clicks one way while handling double clicks a different way.

e.g. a typical file browser highlights a file with a single click and opens the file with a double click, the way we’ve implemented double clicks here wouldn’t work well for that case.
