Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Get size of auto-sized widget

Hi there, I'm trying to get the size of a widget. I know I can do this like in the example below: alt text

However, this doesn't work with an auto-sized widget ("Size to content" inside of a canvas), because it always returns the size the widget has before it gets auto-sized. How can I get the final size the widget has when it's displayed with auto size?

Get Desired Size.

Returns 0,0 in this case, that's not what I need. There's this node:

Auto Size

But instead of just saying if It's autosized or not I need the actual Vector2. :D

Just call the ForceLayoutPrepass BEFORE you return the size of your autosized widget. :)

Get Desired Size is what you are looking for. But you need to call it after some delay.

That's what ForceLayoutPrepass is for. Delay 0.0 should also work but it's more of a hack.

Sorry, forgot to answer this, ForceLayoutPrepass worked for me, thank you! :)

How are you using ForceLayoutPrepass? I can't get the final auto-sized dimensions no matter what I try.
