also it would be good to look into producer-consumer design-pattern,

and using the Event Structure for your GUI.

producer-consumer design pattern separates data acquisition from presenting/acting-on the data. it is like a template of good software architecture for this kind of problem.

 

the event structure can be used for reacting on GUI events like clicking a button, as well as acting on self created user events (this works like a queue, where the event structure can react on messages).

this helps to make it clear where and what you do in regards to user interaction.

The benefits of choosing an appropriate software architecture may not be evident when a project is in its early stages.

However, it helps a lot later, when (very usually) it's needed to add more functionalities and features.

a very simple example:

NOTE: this is a snippet. if you save the .png on your computer, you can then drag+drop it onto a block diagram (directly drag+dropping from the image in the forum does not work anymore unfortunately)
