Can't get my script to run! No dialog box -_-

[Six1Seven1]

Hi all,

Let me begin by saying I am new to coding with Python (about 3 weeks experience), but am quickly learning how to navigate through the API and execute some tasks. I have been following these videos:   click here and learning fast.

BUT I have run into a problem. I am trying to create a little dialogue box within fusion when my script runs. I have defined an event and a handler and all that and still nothing comes up. Here is a breakdown of my code...

1. Random extrusions at start up are created

2. Created a command definition for a button and placed that button inside the toolbar

3. Created an event and handler for the button

4. Created command inputs (selection inputs and then a dropdown)

4. When i click the button in the toolbar.... nothing happens 

I am looking to create a dialogue box which I can then link to  drawing functions. But I can't even get as far as creating a dialogue.

Any help is appreciated.

The API isn't designed to do what you're trying to do within a script.  Typically, when a script is executed, it does what it's supposed to do and then is done.  This means its no longer around to handle the button click. That's why when you click the button nothing happens because the script isn't running any more to listen for the click.

Customization of the user-interface should be done in an add-in.  An add-in differs from a script in that it is started and doesn't stop until Fusion is shut down or the user explicitly stops it using the Scripts and Add-Ins command.  When the add-in is started (which is typically when Fusion starts if the add-in is set to run on startup) it adds its commands to the user-interface and connects t the events it needs to listen for.  Then is continues to run in the background waiting for one of the events to occur.  If one of its buttons is clicked, then the command created event is fired and it can create the dialog and connect to other command related events and finally react the command execute event where the work that command does should be performed.

ekinsb,

Now I feel stupid! I thought that may have been the case but I wasn't exactly sure. None of the sources I read really defined that clearly. Is transferring my current script to an Add-in something that is difficult to do? Or does it just require a few commands? 

Thank you very much!

[ekinsb]

It shouldn't be too difficult.  I would create a new add-in and copy and paste pieces of your script code.  Hopefully this topic on Commands will help, but I'd be interested to hear where it didn't and you still had problems.

ekinsb,

So, i created a new Add-in. The only real difference in code that I see is the stop function. I pasted my code.

The result is that I now have no icon at all in the toolbar and nothing happens when the addin* runs.

Very confused! 

I will look at the documentation you provided, thank you
