[PyQt] Make a exec_() in a Dialog

[rudsonalves at yahoo.com.br]

Hi David,

I need insert operations, as get file parts from internet, in main loop
of the QDialog.

I try to use the QTimer.singleShot to start the wget_file, but it freeze
all dialog buttons (as Cancel Button) until the wget_file routine return.

know who I can make it?
