Earlier in this series of Qt byte sized tutorials, we wrote our first program, a console based "Hello World". In this part, we will build a GUI application (after all Qt is mainly a GUI Framework) using Qt Widgets. In doing so, we will also leverage the functionalities of Slots and Signals, which we learned in previous post. Widgets … Continue reading QT #3 : Hello World using Qt Widgets
QT #2 : Signals and Slots
In this section, we will sneak peak into one of the key concepts introduced by Qt - Signals and Slots. Qt uses Signals and slots for communicating between objects. Or to be more precise, all objects that derieved from QObjects (or one of its subclasses). Objects often want to communicate with each other, particularly in GUI programming where … Continue reading QT #2 : Signals and Slots
Mediator using MassTransit
In our previous blogs, we had visited the Mediator Pattern and also walked through the implementation of Mediator using Mediatr library. In this example, we will look into an alternative library - the MassTransit. Over the years, MassTransit has made its APIs a lot more simpler. I wasn't a huge of the earlier implementations, but the last time I … Continue reading Mediator using MassTransit
gRPC-Web : Using gRPC over browser application
Previously, we created a gRPC server in .NET and connected it using a Flutter Desktop client. In this blog post, we would attempt to connect a web application running on a browser to the gRPC server. We will look at the problems, and the solutions we have, particularly, the gRPC-Web .Net Microsoft have come out … Continue reading gRPC-Web : Using gRPC over browser application
QT #1 : Introduction to QT C++
QT(pronounced as Cute) has been around for a long time now. At the time of writing of this blog, Qt 6.4 is the latest stable version. Why Qt ? Qt is a cross platoform framework for development of application across Windows, Linux, Android, IOS and embedded devices. Cross Platform application development allows developers to use the … Continue reading QT #1 : Introduction to QT C++
Migrating to null safety in Flutter/Dart
If you are starting with Flutter, just like me, and end up having used dependency packages with versions which do not support null safety checks then you are most likely to come across with errors such as the following when you do build. error GBA2BE6E0: A library can't opt out of null safety by default, … Continue reading Migrating to null safety in Flutter/Dart
Process Stream data from gRPC Server using Flutter/Dart
In the earlier post, we addressed how to create a simple Grpc server in C# and consume it using a client developed using Flutter/Dart. We will now take the next step and address how to create expose a streaming remote method in the server and consume the same in the client. Streaming method in Server (C#) … Continue reading Process Stream data from gRPC Server using Flutter/Dart
Create a Flutter gRPC client
In this post, we will address how to create a gRPC client in Flutter and connect to a Server. In order to test our client application, we will quickly build a gRPC service using .Net. gRPC Server (C# .Net) Let us use the Asp.Net core gRPC Service template provided by Visual Studio. With the basic … Continue reading Create a Flutter gRPC client
Generate Password Hash for RabbitMq
In the previous post, we explored how to use docker compose to per-initialize queues in a docker container. The configuration files also provided a way to initialize users. Each of the users where configured with a password, which is given in the configuration file as a hash value comprising of a randomly generated 32 bit salt and … Continue reading Generate Password Hash for RabbitMq
Initialize RabbitMq Docker Container with preconfigured Queues
As we work with docker containers, it is often desired to initialize the containers with specific application needs. One of such requirements was to initialize RabbitMq container with predefined queue. To be more specific, the objective needs to be achieved using docker compose. In this approach, we would use docker volume to map the configurations, which in turn … Continue reading Initialize RabbitMq Docker Container with preconfigured Queues
