在新创建的对象上工作的Groovy Swing数据绑定示例（联机示例不适用）

Posted 2021-02-25

import groovy.swing.SwingBuilder
import groovy.beans.Bindable
 
class MyModel {
   @Bindable int count = 0
}
 
def model = new MyModel()
new SwingBuilder().edt {
  frame(title: "Java Frame", size: [100, 100], locationRelativeTo: null, show: true) {
    gridLayout(cols: 1, rows: 2)
 
    // OLD - does not display until assigned a different value than the original
    // label(text: bind(source: model, sourceProperty: "count", converter: { v ->  v? "Clicked $v times": ''}))
 
    // NEW - this works
    label( text: bind(source: model, sourceProperty: "count", converter: { v -> "Clicked $v times" }) )
 
 
    button("Click me!", actionPerformed: { model.count++ })
  }
}
