Hello all,
i have a question about speed optimization with PyQt, i cant find any
clear explanation about this question
in google, i am developing an app with many .py files, in the beginning i am
using this imports.
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtSql import *
to have no problem using classes but i would like to post any questions i
suppose any people on the list have
to know:
1- if i import a file and this file import the same, it is imported two times
wasting the same time in the
same imports other time?
main.py
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtSql import *
import testdlg
testdlg.py
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtSql import *
2- i have changed any files to import like this:
from PyQt4.QtCore import QRegExp, QString, Qt, SIGNAL, SLOT, QVariant, QChar
from PyQt4.QtGui import QLabel, QDialog, QLineEdit, QDialogButtonBox,
QGridLayout, QMessageBox, QApplication,
QIcon, QInputDialog
from PyQt4.QtSql import QSqlQuery
i know other people (and pyuic4) use this :
from PyQt4 import QtCore
and later use ever first QtCore in classes names "QtCore.QString" but i dont
like to write too much
unnecessary code when i know i will not have name collision, any other way to
speed up the imports?
3- is this really important to speed up the application?
Best Regards,
Miguel Angel.
