Official Interacting with subsections of text.

I'm not sure if this is the right place to ask about it but using link tag can we implement things like adding effects to sections of texts?
Like a shake effect, resizing text or changing color, etc?
Can we get access to the vertex of each letter?

 

Hi, is it possible to make TextField also support rich text and text interaction? This function is very important to me, even imgui supports these, I hope uitoolkit can support it as soon as possible, thank you very much.

 

The linked package seems to be missing the cursor asset... no big deal but just thought I'd point that out

 

Will UI Toolkit links support EditorGUI.hyperLinkClicked?

 

Hello,
here is my use case:
I was making a stack-trace view and wanted the same behavior of opening the file at a specific line from the Console window.
I checked the CsReference repo and noticed that to open the file Console Window is using a callback that is always registered to `EditorGUI.hyperLinkClicked` and the method to open the file within it is internal.
This is mentioned in the documentation as well, although it does not explain how to format the path with the line number:

The logic for opening a file like that is missing in the UI toolkit's href tag, at least it wasn't working for me.
In the end, I used the <link> tag together with the public API I found `InternalEditorUtility.OpenFileAtLineExternal(filePath, line)` this API is undocumented but provides the exact behavior that I needed.

 

Hello, how long will it take for TextField to support rich text?

 

The PointerUpLinkTagEvent stops working after a while in very strange ways. I am overlaying a popup, with buttons inside. When I click on the buttons, oftentimes the text stops working afterwards.

That is, assume I create the popup, add it to the hierarchy, interact with it (particularly the buttons), then close it (i.e., remove it from the hierarchy), and then try to interact with the text on my screen. Such a text has the `PointerUpLinkTagEvent` attached to individual words, but for some reason, it stops working.

I thought it had something to do with event propagation, but I doubt it because I already tried removing the calls I was doing to that kind of methods.

Unity, is this experimental tool bug-free? I can't explain why the `PointerUpLinkTagEvent` would sometimes work, and sometimes it would not.

 

Shouldn't this be called

• PointerExitLinkTagEvent
• PointerEnterLinkTagEvent

(instad of Out / Over)
?

And where is the Clicked Event?

 

I suspect garbage collection in C# may be doing some very weird stuff with event callbacks. Ultimately, I was only able to workaround the issue by registering and unregistering the callbacks constantly on all of my text labels. In other words, I am resetting everything. I read on this thread (https://forum.unity.com/threads/qui...acks-on-ui-elements-textfield-button.1044016/) proposals to make it easier to debug events. It would be ideal if I could see in the debugger the callbacks attached to the events of a visual element.

UPDATE: I don't know why it seems I need to "force reset" the labels to apply the links, but I've also realized that modifying the string to a new value, and then to the old value, helped to make sure the link events worked.

 

Hey,

I do have an issue with this example.
While using a simple Rich text link the link turns black instead of blue.

I am using the same exact rich text link as the example. I am simply putting the UIDocument "LinkTag" from the package in a new scene in a UI document with a default panel settings.

Without any additionnal code, the first line is correctly themed but not clickable while the second line is clickable but not themed properly (underline but not blue).

Do you know where this could be coming from ?
I am using Unity 2023.2.5f1.

 

Any update on when this will be available?

I'm looking for some solution to be able to make certain words in a text have a pill-shaped background and make them hoverable and clickable. Is there any way to do this today?

 

The rich text is working and is very simple. It is simply not FULLY working as intended since the color is not working properly. There is an easy but dirty patch by adding a color tag with it...

You can add a clickable link by simple putting your link in this format :
<color=blue><a href="https://www.google.com/"><u>Google</u></a></color>

To detect a click on the link, you can look into the provided package, there is an implementation with some code.

 

Bump!

 

Hey, any updates on this?

Is there a way to do this in the newest version?

 

Thanks a lot for adding this! But is there a way to disable the native hyperlink handling when using the <a href> tag (in cases where we have user created text, for example)?

 

u should also be able to just replace("<", "&lt;"), (">", "&gt;") for example on any string from the user. i would imagine this works in Unity (but could be mistaken.. just figured I'd mention it, since that's an easy/typical solution if so).

Edit: I wrote the above assuming this meant preventing <a> tags from being parsed as a link within HTML (just showing the < and > symbols instead). If it's plain text with simple replacement for <a> tags only (no other HTML supported), then the above suggestion wouldn't work (because replacement would just show "&lt;" instead of "<" like it would for actual HTML).

 

When rich text support for TextFields is coming? It is mentioned it was planned for 2022, two years later still not implemented.

 

This feature was added in 2022, but events are still in experimental stage.
PointerOverLinkTagEvent - does not trigger the event when pointer is hovering the link. It is triggered only when clicked on the link.
PointerOutLinkTagEvent - same thing here, triggered when pointer is released over the link, not when it leaves the link area.
PointerMoveLinkTagEvent - Does not work at all
