Pyside2 - How to create notes/comments and display them corresponding to selected item from list

younglegend

I have been creating a tool that displays multiple file versions from a folder in a QListWidget.

I would like to save notes/comments for each version and display them using QTextEdit corresponding to the item in the list that i click. Like a version manger. How shall i go about this? Kinda stuck... Thank you!

import sys
from PySide2 import QtCore, QtGui, QtWidgets


class Dialog(QtWidgets.QDialog):
    NumList = 20

    def __init__(self):
        super(Dialog, self).__init__()

        self.createHorizontalGroupBox()
        self.createVerticalGroupBox()
        mainLayout = QtWidgets.QVBoxLayout()
        mainLayout.addWidget(self.verticalGroupBox)
        mainLayout.addWidget(self.horizontalGroupBox)
        self.setWindowTitle("File Manager v1.0")
        self.setLayout(mainLayout)



    def createVerticalGroupBox(self):
        self.verticalGroupBox = QtWidgets.QGroupBox("List Files")
        layout = QtWidgets.QVBoxLayout()
        layout.setContentsMargins(25,25,25,25)
        layout.setSpacing(7)

        file_listbox = QtWidgets.QListWidget()
        for i in range(Dialog.NumList):
            file_list = ("File_v%d" % (i+1))
            file_listbox.addItem(file_list)
        layout.addWidget(file_listbox)

        self.verticalGroupBox.setLayout(layout)


    def createHorizontalGroupBox(self):
        self.horizontalGroupBox = QtWidgets.QGroupBox("Notes")
        layoutB = QtWidgets.QGridLayout()
        layoutB.setContentsMargins(25, 25, 25, 25)
        layoutB.setSpacing(7)
        layoutB.setColumnStretch(0,5)

        self.notes_editor = QtWidgets.QTextEdit()
        self.notes_editor.setPlainText("Test..")
        layoutB.addWidget(self.notes_editor,0, 2, 4, 1)

        self.edit_button = QtWidgets.QPushButton("Edit..")
        layoutB.addWidget(self.edit_button,0,5)

        self.save_button = QtWidgets.QPushButton("Save")
        layoutB.addWidget(self.save_button,1,5)

        self.horizontalGroupBox.setLayout(layoutB)





app = QtWidgets.QApplication(sys.argv)
dialog = Dialog()
sys.exit(dialog.exec_())

Hi and welcome to devnet,

How are you storing these different file versions ?

younglegend

@SGaist Cheers!
If i understood you right, i'm storing these versions as fileName_v001, fileName_v002 and so on...

SGaist

Then this might come as a silly question but since there's VCS like git, are you sure you are using the tool ?

Anyway, for your current system, you could have a second file following the name schema with a different extension for the notes. Or have them in a SQLite database.

@SGaist That's where i'm stuck, i have no idea how to implement it with PySide. I like to manually type my tools using examples/forum guides as reference. But examples for vcs with Qt is something i never came across with google search. Which is surprising...

@younglegend said in Pyside2 - How to create notes/comments and display them corresponding to selected item from list:

Well, it does not have anything to do with Qt actually. Qt is a C++ framework, so you write code using Qt as framework. In your case it's Python code, but this does not change anything. Just use a VCS as you could do with any project.

@younglegend
I'm not suggesting it's a good idea to do it this way, but....

If you do not want to go down the road of a VCS tool or a database or similar to hold your file versions and comments (which is a whole different ballgame), but instead stick to no more than the simple file handling you currently have, then:

Your files seem to be named File_vnumber. So store your comments in similarly named files, so you can pair them against your file version files. Either e.g. File_Comment_vnumber, or create a sub-directory named e.g. Comments and store the corresponding comments in the same-named File_vnumber but in the Comments sub-directory....

@JonB I would gladly avoid vcs as my tool is fairly simple. But the problem is, being a beginner myself i couldn't find a forum discussion regarding this topic or a similar example i could improvise on.

JonB

@younglegend
Which is why I have suggested a very simple solution for you just using similarly named files. Whether that's adequate for whatever you are producing only you know.

younglegend

@Denni-0 Thanks for such a nice explanation Denni! It looks cleaner now. And yes, switching to pyside was pretty straight forward.

I actually had a very different kind of layout workflow before. Then i came across some examples that came with pyside packages folder which had everything i need. almost....

younglegend

Bump..! Any help with this please? Still stuck at the same place with little to no progress..

JonB

@younglegend
Help with what exactly? I thought you had copied Denni's stuff or whatever? I thought you were going to implemented what i suggested about keeping your comment in a "shadow" file for each file?

Just to be 100% clear again. If you want a "proper" program for managing file versions + comments, you don't want to write it yourself, you should use a VCS out there like git or github. If however you want to knock up something to learn Qt, you could follow my simple suggestion, or you could get (a lot) more involved by doing it via a database from Qt....
