[Qt-interest] Updating the TableWidgetItem slows down the operation significantly.

[Yong Zhang]

Hi All,

I use a QTableWidget to display the current location values (x, y) of 
the mouse on the screen. I display the mouse location using a hand image 
on the screen. When the mouse moves, the mouse image is updated on the 
screen to indicate the new location. My goal is to also update the 
location values (x, y) in the QTableWidget as two QTableWidgetItems. The 
system works well, however, I found that it significantly slows down the 
operations, that is, the update of the mouse image on the screen is very 
slow and the mouse movements are not smooth. When I do not update the 
location values in the QTableWidget, I can move the mouse around very 
smoothly and the mouse image is also updated very smoothly. My question 
is, is there anyway to make it fast and smooth enough to update the 
information in the QTableWidget?

Thank you very much,

Yong
