Cross platform compatible GUI application with C++ core logic

[prasad2023]

Hi all,

We are analyzing the technologies to choose for a desktop application for professional traders on Windows/Linux/Mac OS. currently, we are thinking for qt gui with c++ core logic for all os. This application primarily needs rich gui, consume rest apis, and consume push notifications from websockets.

My basic queries are:

1. Are qt gui and c++ backend are right technologies to develop such application? if not, suggest any.
2. afaik, qt apis are wrappers around native os apis. will it impact performance?
3. is there any alternative for c++ for this requirement.

Thanks in advance.

Hi,

1. Yes and there's also work in progress to improve web technology integration
2. Performance of what ?
3. That offers support for all your requirements ? I don't think so.

Note that depending on your needs, you may also tape into KDE's set of frameworks that complements Qt.

Obviously, you will get a "yes" here.

There is a very large number of applications written using Qt that are similar to what you describe.
With "similar" I don't specifically mean trading applications, I mean professional desktop applications that use high-volumes of data and aim at a great user interface.

This is not a good description. Qt is a toolkit and covers a LOT of ground and provides a very large number of features.
Any other toolkits, including the ones from Windows or Mac will basically have the same approach that Qt has for most of these features.
Therefore it won't be slower than those.

The term "wrapped" I have mostly seen used for widgets. The point there is that a Qt app can look identical to a native Windows or Mac application. If you so choose. I don't think you need to worry about that being slow.

I don't think there is anything out there that will be good enough for such an application.
