I must say that the recently updated TouchGFX documentation is excellent. Great job!
I apologize if I am missing the obvious, but is there a way to pass more than one value by way of an "action" to a Custom Container?
I am referencing the following tutorial:
https://support.touchgfx.com/docs/tutorials/tutorial-05/
I am working on a Custom Container with a Scrollwheel in it and I would like to add a custom action to be able to change the text of a specified element (a second parameter) programmatically. I tried the "custom" and when trying to add the action, I was not able to get it to accept a multiple parameter virtual function or when selecting "Execute C++ code".
Any help would be appreciated.
Solved! Go to Solution.

@scottSD Your input is really appreciated. We would like to make this more obvious.
What you can do for now:
Instead of having an action/method with two parameters, you could create an action/method that expects one struct parameter.
In Designer an example definition would be:
And an example usage would be:
Hope this helps.

I found out that when adding the "type", you can enter what types you want, separated by a comma. I had previously attempted to copy/paste a type with a variable from some code I was using:
Unicode::UnicodeChar* uCharText, uint8_t index
All that is necessary are the types:
Unicode::UnicodeChar* , uint8_t
Which creates a virtual function prototype in the base of the Custom Container:
virtual void SetElementText(Unicode::UnicodeChar* , uint8_t value);
And things work fine when calling this function.
Like I said, I was probably missing the obvious....
Anyway, my initial compliment of the new documentation stands. It is done very well.

Thanks, Scott! We put a lot of effort into it - Feel free to give us some input if you feel something is not clear enough =)
Re: your question, good job on finding out on your own. My response would have been that there's no obvious way to do what you wanted =) There'll be better support from the designer on this particular "issue" in the future.

That is helpful! I will get the hang of it one of these days ;) .
Overall, I think the new documentation is awesome.
I do appreciate that one can use the Designer to create virtual functions that can be used in user code.
