Can addon behave like the normal buiding elements tools ?

When using walls, colums etc in AC the tool stays active after you finish your input.

Is it possible to get this behaviour for an addon?

I have a palette with an icon that let me place a text element, but i have to reclick the icon for each new text element.

Is there a way to make this comand 'sticky' so i can reuse it multiple time ?

Hi!

Are you using an `IconButton`?
I think the behavior you want should work with an `IconPushCheck`.

I do use an iconButton on my palette, yes.

The issue is not to retain some parameter that works just fine, the issue is that I want the command linked to that button to stay active once the first iteration is finished.

In the palette I have a buttonclicked event observer, what I want it the function lnked to the button to be called again once it completes.

Thanks for the clarification. I misunderstood your question.

If I understand it correctly now, I think you would have to manage that manually by e.g. having a loop in your ButtonClicked event observer and stop the loop once the user cancels the input. For example the function APIIo_GetPointID returns APIERR_CANCEL when users cancel the input.

Does this address your issue? Otherwise could you provide the code of your ButtonClicked event observer?

Sorry I forgot to come back to say I found the solution.

Like you suggested i changed my function return type to GSErrCode and wrapped it in a do-while loop.

GSErrCode Do_iterate() { GSErrCode err; do { ACAPI_CallUndoableCommand("Iterated element", [&]() -> GSErrCode { err = Do_CreateText(); return NoError; }); } while (err == NoError); return err; }

my Do_CreateText function calls ClickAPoint() from APICommon.c whick does return APIERR_Cancel

Thanks for the help.
