Upgrade 05: PyQt6 Desktop App Template

I have added CRUD(create/read/update/delete) for users with search function which is similar to SAP's search help. It can be accessed from the Admin pull-down menu.

The latest version can be downloaded in this github repository: python_desktop_app_template

 The Output:

Upgrade 04: PyQt6 Desktop App Template

The desktop app template has been upgraded to include a tool to update code of the mdi window without exiting entirely from the application. 

Procedure:

Close the main window, update the code from the IDE window and press the "Recompile" button. The main window will be reloaded with the new changes.

The output:

Upgrade 03: PyQt6 Desktop App Template

The Desktop App Template has been upgraded to include global variables(for example: username must be stored in a global variable upon successful login), the global variable(username) is displayed permanently at right-most corner of the status bar, I did some minor code refactoring of the main window by adding a separate function for configuring the right sidebar and lastly, I made the side menu bar(treeview) database driven which means the treeview items are stored in a mysql table.

The output is the same as the original screen(from Upgrade 02) with the exception of the username getting displayed permanently at the status bar.


The mysql table definition:

CREATE TABLE `tbsidebar` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `parent` varchar(25) NOT NULL,
 `node1` int(11) NOT NULL,
 `name` varchar(25) NOT NULL,
 `node_name` varchar(25) NOT NULL,
 PRIMARY KEY (`id`)
 ) ENGINE=MyISAM AUTO_INCREMENT=16 DEFAULT CHARSET=latin1

Upgrade 02: PyQt6 Desktop App Template

This demo program add another improvement of the desk top app template(original post here). The newly added feature is a the ability to login, a simple password encryption(sha256) and connecting to sa mysql database. Also added a top layer file that should perform system configuration before the splash screen is shown.

 

Login Info:

  UserName : admin

  Password :  Appl3Tr33.456

The output:

 


The mysql table:

CREATE TABLE `tbusr` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `username` varchar(256) NOT NULL,
 `userpassword` varchar(2048) NOT NULL,
 PRIMARY KEY (`id`),
 UNIQUE KEY `ind_usr` (`username`)
 ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=latin1

password_hash = hashlib.pbkdf2_hmac("sha256", password, salt, 100000)

salt = b'4\xa8y\x8e\xca\xfb\x7f\x8e\xd5\x97v\x14\xc7[Z\xd0'
print(salt)
print(password_hash)

Upgrade 01: PyQt6 Desktop App Template

This demo program shows another way to implement the Desktop App Template using modularized approach(I created the import.py to handle import common libraries of the the window files(splash, login, mainw), a sidebar menu has been added which is from the previous post "Create Treeview with PyQt6" and I added a progress bar at the newly added status of the login screen of which code is derrived from my previous post "Progressbar with PyQt6".  If you prefer the old version you may still access it with the original post.
