Notes for Qt remote machine development

A strange problem in recent projects is that when the final m_lastpos is recorded as the middle position of the current widget, qcursor is set as the current middle position.

At this time, when I started to move, I found that the offset has a very strange maximum value. Later I found that because my working environment is a remote machine environment, when I call the global qcursor of the system :: when setpos is used, the cursor is still in my original place. At this time, the cursor jump will naturally occur when offset is used.

The solution is to record the currentpos (m_lastpos = qcursor: pos (), in this way, the offset is too large.
