controller: fix the bug on the event of dockingconview
Because handling the mouse event of dockingconview is incorrect,
the controller could be moved unintenionally in certain case.
Therefore, I added codes for setting dockingconview's status correctly.
Also the enumeration like CONVIEW_* is designed to react the left mouse button.
