But while the actual values can contain more decimal places (as shown by the ```println``` statement, there’s still no visual feedback inside the spinner text field:\r\n\u003e \r\n\u003e ```#@ Double (label=\"Distance\", min=0, max=0.05, value=0.01780, persist=false, stepSize=0.0001, style=slider) distance```\r\n```println distance```\r\n\u003e \r\n\u003e There’s no parameter attribute for number formats, but we could maybe use the `style` attribute for this; in any case we should try to guess a suitable spinner number format from the combination of min, max and stepSize, or from the default value…\"","author":{"url":"https://github.com/etadobson","@type":"Person","name":"etadobson"},"datePublished":"2019-02-14T14:53:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/45/scijava-ui-swing/issues/45"}
