Resize background to match UIGrid

[drawmaster77]

Hi,

Sorry if this was asked many times before, I couldn't find it.

I have a UIGrid which I populate with items at a run-time. UIGrid itself is located inside a frame (UISprite) which needs to be resized to match updated grid's size (as opposed to clipping contents). How can that be done?

Thanks

Make the sprite be separate from the grid and put the EnvelopContent script on it, targeting your grid.

I think there's possibly a bug in SetRect code UIWidget.cs line 623

1. width = finalWidth;
2. height = finalHeight;
3.  

should probably be

1. this.width = finalWidth;
2. this.height = finalHeight;
3.  

since width/height is also a function parameter. It wasn't really working for me until I made that change anyway.

Thanks

That's what it is. You should always update to the latest first.

sorry about that.

But it looks like it's enveloping everything, including stuff clipped by panels? I have a scrollview in one of the items I am trying to envelop content on, is there anyway to only envelop visible items?

Thanks

No, it doesn't consider clipping. It's a simple example script that shows the 3 lines of code necessary to resize one widget to envelop the content of some target object. If you want it to take clipping into consideration, write a custom function instead of calling NGUIMath.CalculateRelativeWidgetBounds, or at least skip the scroll view. However if I was at this point, I'd start wondering why I need to resize one widget to envelop the bounds of something that has been clipped, and why not just leave the widget with a fixed size.

Well I was trying to do a fancy pop-up window thingy which would scale based on amount of text in it and also contain a long list of options (inside the UIGrid), here's an early screenshot:

(textboxes can be of variable height)

I was using a widget as a way to calculate center of my object, so that I can correctly position it next to the node selected.

I think I will just write my own script to calculate the size, as number of objects inside that affect it doesn't really change.

Thanks
