Detailed Description

A widget which displays output image from a CConnectDesktop and sends input keypresses and mouse activity to the CConnectDesktop.

When the viewer receives new image output from the CConnectDesktop, it will update the display by calling slotUpdateRect.
When the mouse update, then call slotUpdateCursor ; if update position, then call slotUpdateCursorPosition
