By taking Treeview: Basic example, it can be shown how to customize a basic treeview. In this case, we create a style "mystyle.Treeview" with the following code (see the comments to understand what each line does): style = ttk.Style() style.configure("mystyle.Treeview", highli...

A simple OGL 4.0 GLSL shader program that shows the use of a interface block and a uniform block on a Cook-Torrance microfacet light model implementation. The program is executed with a phyton script. To run the script, PyOpenGL and NumPy must be installed. An Interface Block is a group of GLSL in...

The widget ttk.progress is useful when dealing with long computations so that the user knows that the program is running. Following, an example updating a progressbar each 0.5 seconds is given: Function updating the progressbar def progress(currentValue): progressbar["value"]=curren...

This is how you install the gcloud command-line tool, which is a part of the Google Cloud SDK. $ curl https://sdk.cloud.google.com | bash

Authorize yourself, you will be navigated to Google Sign In page. $ gcloud auth login Initialize or reinitialize the gcloud, you can set your configurations here. $ gcloud init Display information about the current gcloud environment. $ gcloud info Display the list of active SDK configur...

Create a Cloud SQL instance $dsn = "/cloudsql/PROJECT:REGION:INSTANCE;dbname=DATABASE"; $user = "USER"; $password = "PASSWORD"; $db = new PDO($dsn, $user, $password); //Whatever is your favorite MySQL connection method The important part here is /cloudsql/PRO...

App Engine does not allow writing to files, instead write to and read from Cloud Storage. Write to Cloud Storage $file = 'gs://<your-bucket>/hello.txt'; file_put_contents($file, 'hello world'); Read from Cloud Storage $contents = file_get_contents($file); var_dump($contents);

Simply use PHP’s standard syslog function to write logs syslog(LOG_INFO, "Authorized access"); syslog(LOG_WARNING, "Unauthorized access"); You can see the logs from "Stackdriver Logging" ( https://console.cloud.google.com/logs )

The QSqlDatabase class provides an interface for accessing a database through a connection. An instance of QSqlDatabase represents the connection. The connection provides access to the database via one of the supported database drivers. Make sure to Add QT += SQL in the .pro file. Assume an SQ...

It's often convenient to separate the SQL query from the actual values. This can be done using placeholders. Qt supports two placeholder syntaxes: named binding and positional binding. named binding: QSqlQuery query; query.prepare("INSERT INTO employee (id, name, salary) VALUES (:id, :name,...
