Issue: auto sizing text from preset block size

[drew-512]

I am unable to have text auto-size properly into a TextBlock, even when block as a preset block size (hard coded V or %).

Repro:

1. Open UIPlayground and enter play mode
2. Select the "Label" game object for for the "Dark Theme" button
3. Disable auto shrink for the Label on X and Y (so that it's a fixed V or %)
4. Enable Auto-Size on the text
   Expected: text font size expands to fit block size (Y in this case)
   Actual: TMP chooses a broken font size

Is this issue something that is known or is there a different official way to autosize text for a given fixed size? I get that complexities abound for multi-line and/or wrap auto-sizing, but I'm thinking this should be possible for single-line text size fitting (or hopefully possible before long?)

Thanks!

Using AutoSize on the TextMeshPro - TextBlock will work, but you may not see anything change if you only disable Shrink.

When AutoSize is enabled on the TextMeshPro - TextBlock component, the "fillable size" is defined by the TextBlock's Size (which you can visualize by enabling the UI Block Tool). If you only disable Shrink, the text has no room to expand because it was already matching the "fillable size" - if you make the TextBlock's Size larger or smaller, then the text will adjust.

Also, one thing worth verifying (trips me up all the time) is that Max font size on the TMP component is large enough for the text to scale as expected. It defaults to 2, which will be too small in the UIPlayground scene - but something like 1000 will be sufficient.

Ah yes, thank you -- had a bad max font size set. Yay, no issue.

Not trying to make extra work for y'all but I bet this might reoccur with other people. Perhaps it makes sense to add a checkbox for autosizing a TextBlock and that manages a couple of the other UI elements (disables Font Size field or maybe it turns into a "Max Font Size"), etc. Or warning text in the docs to look out for that. Or maybe set the default max text size in the TMP item to a larger value to catch most cases. Some ideas anyway!
