您可以将面板放在 a 内vbox
,然后您将面板放在 a 内scrollPane
。
从上一个问题中获取代码,您最终会得到如下内容:
import groovy.swing.SwingBuilder
import javax.swing.WindowConstants as WC
import javax.swing.JOptionPane
import javax.swing.JScrollPane
import javax.swing.BoxLayout as BXL
int numPanels = 20
swing = new SwingBuilder()
frame = swing.frame(title:'test', pack:true, visible:true, defaultCloseOperation:WC.HIDE_ON_CLOSE) {
panel(id:'mainPanel'){
scrollPane( verticalScrollBarPolicy:JScrollPane.VERTICAL_SCROLLBAR_ALWAYS ) {
vbox {
(1..numPanels).each { num ->
def panelID = "panel$num"
def pane = panel( alignmentX:0f, id:panelID, background:java.awt.Color.GREEN ) {
label('description')
textField( id: "description$num", text:panelID, columns: 70 )
button( id: "buttonpanel$num", text:panelID, actionPerformed:{
swing."$panelID".background = java.awt.Color.RED
} )
}
}
}
}
boxLayout(axis: BXL.Y_AXIS)
panel(id:'secondPanel' , alignmentX: 0f){
button('Quit', actionPerformed:{
frame.visible = false
})
}
}
}
frame.size = [ frame.width, 600 ]
