Hello,
i have created one pyqt app we are using in my company, it is warehouse
application, any fast workers
seems to be faster that application because of fast bar code scanners, they are
introducing items in a
QTableView with an internal QAbstractTableModel subclass and using
QItemDelegate, i am using a python class to
store the columns in QVariant, every line it is a python object of this class,
i have made many profiling and
fix all the bottlenecks, when they read too fast it is like the return keypress
after read the bar code doesnt
works, i can see in the lineedit of the cell many ean13 codes toguether and it
fails to load because it doesnt
exist. To me it seems like a qt problem because it doesnt close the editor when
receive a return keypressevent
and read the next code in the same editor, i have been to get 4 ean13 in the
same lineEdit if i try very fast,
the machine where i am using the application is a pentium4 1.8 so it should be
sufficient to use the app
correctly, the cpu usage goes on 40% to python, 20% to Xorg, i have tried with
psyco and timing the load
item/create new line python code it is 1.3 times faster than before but i have
the same problem with the
editor, anyone has any idea how i can fix this? other question can i develop a
model to the tableview or
create gui code in c++ and use it from the pyQt application?
Regards,
Miguel Angel.
