Question

如何向下面定义的表添加标题？

import groovy.swing.SwingBuilder

data = [[first:'qwer', last:'asdf'],
        [first:'zxcv', last:'tyui'],
        [first:'ghjk', last:'bnm']]

swing = new SwingBuilder()
frame = swing.frame(title:'table test'){
    table {
        tableModel( list : data ) {
            propertyColumn(header:'First Name', propertyName:'first')
            propertyColumn(header:'last Name', propertyName:'last')
        }
    }
}
frame.pack()
frame.show()

Answer 1

如果将表格放在滚动窗格中，则会显示标题：

import groovy.swing.SwingBuilder

data = [[first:'qwer', last:'asdf'],
        [first:'zxcv', last:'tyui'],
        [first:'ghjk', last:'bnm']]

swing = new SwingBuilder()
frame = swing.frame(title:'table test'){
  scrollPane {
    table {
        tableModel( list : data ) {
            propertyColumn(header:'First Name', propertyName:'first')
            propertyColumn(header:'last Name', propertyName:'last')
        }
    }
  }
}
frame.pack()
frame.show()

表头是一个单独的小部件，必须显式添加。

import groovy.swing.SwingBuilder
import java.awt.BorderLayout

data = [[first:'qwer', last:'asdf'],
        [first:'zxcv', last:'tyui'],
        [first:'ghjk', last:'bnm']]

swing = new SwingBuilder()
frame = swing.frame(title:'table test'){
    def tab = table(constraints:BorderLayout.CENTER) {
        tableModel( list : data ) {
            propertyColumn(header:'First Name', propertyName:'first')
            propertyColumn(header:'Last Name', propertyName:'last')
        }
    }
    widget(constraints:BorderLayout.NORTH, tab.tableHeader)
}
frame.pack()
frame.show()
