Hi,thanks who answered my first question.
Now I need further help:
I use a thread to get data from a sever through
PDU. Follows is the pseudocode inside this thread.
while(1){
receive PDU packet from
socket;
analyze PDU packet and get a point
value;
draw this point to the drawing
area;
update some labels
accordingly;
}
if I put the above code directly in the drawing area expose
event, there is nothing in the drawing area, and also the labels do not
change.
Could anyone tell me how to draw these points to the drawing
area and how to update the labels? Are there any example codes?
Thanks in advance.
