I could use some n00b level help. I saw the announcement for 0.8.0 and decided to give it a try. However, I seem to be missing something important. More in thread:

[Ruckus]

When I run the code below (JVM), I see only a blank window, and init and Hello World! are printed to the console. rendering is never printed, and nothing shows up in the window.

Am I missing something to get the rendering to actually start?

Untitled.cpp

Using a view { ... } block in the app init appears to work fine. Not sure what the difference is, as ViewBuilder appears to be a very simple wrapper.

Views will only render if they have a non-zero size. You need to set some size to UserInfo, since it defaults to 0.

[Ruckus]

Ah, I see. So views don't automatically calculate their size bases on contents?

[Ruckus]

I guess that makes sense if everything is essentially just canvas draws. What would be the appropriate way to make this view match its size automatically?

[Nick]

They don't.

[Ruckus]

Also, why does the view { ... } block work?

[Nick]

TextMetrics is used for calculating the size of text. So you can compute the size upon unit in the UserInfo and set a size then. Of course you're drawing two lines, so you'd account for that in the calculation.

[Nick]

Work as in?

[Ruckus]

Ah, I see. Also, the block version does not appear to work for me now. I must have had a size = display.size in there the first time and not noticed.

Thanks for the help!

(By works I meant it was showing up in the window and printing to the console)

[Nick]

I see. You can also set a Layout on the display to have it manage the size of the top level Views.
