What is data-wails-* for?

[Robert-M-Muench]

I tried to create a super simple FORM with an onsubmit function. But my function code was never called.

I created a plain vanilla project, where the greet button works. I added my form, nothing, same as my code. I removed the data-wails-no-drag tag (?) and the vanilla code didn't work too.

So, it seems to get any interaction up & running I somehow need to use this tag (?).

• What is it?
• Is there a documentation?
• When to use it?
• Where to use it?
• Are there are other tags I should be aware about?

The docs for it are here: https://wails.io/docs/guides/frameless
It's unrelated to javascript or form processing.

I've just realised search in the docs aren't enabled. I'll fix that.

Why are buttons becoming draggable? You can control this by turning drag off for the element. The page I linked to has the details

[Robert-M-Muench]

To summarize the problem, which either is a bug or a subtle thing, one has to know:

If a button is within a section that is marked with data-wails-drag the button is no longer firing click events.

[leaanthony]

That's correct and not a bug. If you want a button to be clickable, it shouldn't be a drag handle. I think passing through the event as well as dragging the window would be confusing. What do you think?

[Robert-M-Muench]

I would default to implicitly make all clickable things, no-drag. It doesn't make sense to use these for dragging. I'm sure most people forget to add the no-drag (if the rest is draggable) in the first round.

However, IIRC I removed all the tags and the problem persisted like no tag implicitly become data-wails-drag but I might be wrong.

[leaanthony]

I think this would be too hard. You can add onClick to any element. I suspect the drag handle use case to be limited to a section of the page without clickable elements.

[Robert-M-Muench]

Even more strange is, that I use Frameless: false, in main.go

Shouldn't this avoid any frameless side effects?

[leaanthony]

There's no side effect magic. If you want an element to be draggable, add the attribute. Whether it's frameless or not doesn't matter.

[Robert-M-Muench]

I was confused because of the link to the frameless page. Gave me a wrong context.

[leaanthony]

That's fair. Where would you expect that information to be?

[Robert-M-Muench]

I would split the frameless and draggable stuff into two separate pages. Give it an own page, as it's a topic of its own.

[leaanthony]

There wouldn't really be a frameless page though without draggable. I'll have a think about it
