PYRCC5 convert RESOURCES.QRC to py file

The RESOURCES.QRC needs to be converted to a PY file via PYRCC5 and introduced in the main program.

Pyrcc5-o resources_rc.py RESOURCES.QRC

the 6th instance of the fast programming of the Python Qt GUI with python3+pyqt5 the main window original January 11, 2017 10:14:12 Tags: python/qt/gui/pyqt

This article is an example of the 6th chapter of the fast programming of the Python Qt GUI MainWindow rewritten as a PYTHON3+PYQT5 encoding. Changes, I found a lot of pits to change, the following is about to list some of the key needs to be changed, and with the revised Code, the code in the python3.5+pyqt5.7 environment to run and test normal. Please refer to the study.
This instance has the following programs:
/home/yrd/eric_workspace/charter6/ui_newimagedlg.py
/home/yrd/eric_workspace/charter6/ newimagedlg.py
/home/yrd/eric_workspace/charter6/helpform.py
/home/yrd/eric_workspace/charter6/ resizedlg.py
/home/yrd/eric_workspace/charter6/mainwindow.py
Resource file:
/home/yrd/eric_workspace/charter6/ RESOURCES.QRC
/home/yrd/eric_workspace/charter6/images
/home/yrd/eric_workspace/charter6/help
You can find the code resources for the author's book on the Internet to get the resource files.
Key content:
1, because Settings.value ("RecentFiles") is itself a list type,
Self.recentfiles = Settings.value ("RecentFiles"). Tostringlist ()
changed to
Self.recentfiles=settings.value ("RecentFiles")
2, type conversion problem

Self.restoregeometry (
      settings.value ("Mainwindow/geometry"). Tobytearray ())
self.restorestate ( Settings.value ("Mainwindow/state"). Tobytearray ())

Changed to

Self.restoregeometry (
     Qbytearray (Settings.value ("Mainwindow/geometry"))
Self.restorestate (QByteArray ( Settings.value ("Mainwindow/state")))  

3, the problem of introduction to the library, there are many, only one example:
From Pyqt5.qtprintsupport import Qprinter,qprintdialog
4, the pits in the instance, Qfiledialog.getsavefilename and qfiledialog.getopenfilename return the result is a tupple. The first is the filename and the second is the file type.

Fname,tpye = Qfiledialog.getsavefilename (self,
       "image changer-save image", fname,
       "image files ({0})". Format ( ". Join (formats)))

Fname,tpye = Qfiledialog.getopenfilename (self,
       " image changer-choose image ", dir,
       " Image files ({0}) ". Format (" ". Join (formats)))

The qstring type should be replaced with the Python string type in 5,PYQT5 development. Self.recentfiles is a list type, so use append or insert rather than prepend.

    def addrecentfile (self, fname):
        If fname are None:
            return
        if not Self.recentFiles.contains (fname):
            Self.recentFiles.prepend (QString (fname)) while
            Self.recentFiles.count () > 9:
                self.recentFiles.takeLast ()
change
    to Def addrecentfile (self, fname):
        If fname is None:
            return
        if fname not in self.recentfiles:< C12/>self.recentfiles.insert (0,fname) while
            len (self.recentfiles) > 9:
                self.recentFiles.pop ()

6, the problem of the signal slot, now for example:
Self.connect (Action, SIGNAL ("triggered ()"), Self.loadfile)
Change into
Action.triggered[bool].connect (Self.loadfile)
The trough Self.loadfile also made some changes according to the actual situation.

The RESOURCES.QRC needs to be converted to a PY file via PYRCC5 and introduced in the main program.
