编辑AS3中的组合框

Question

我在编辑AS3中的组合框时遇到问题。任何人都可以告诉我为什么我的ComboBox消失了吗？感谢所有提前帮助。

import fl.controls.ComboBox; 
import fl.data.DataProvider; 


var typeTextFormat:TextFormat = new TextFormat(); 
typeTextFormat.color = 0xFFCC00; 
typeTextFormat.size = 11; 
typeTextFormat.font = "Verdana"; 


var typeButton:Sprite = new Sprite(); 
addChild(typeButton); 
typeButton.graphics.beginFill(0x000000); 
typeButton.graphics.drawRect(0, 0, 109, 32); 
typeButton.graphics.endFill(); 
typeButton.alpha = 0.75; 
typeButton.filters = [new GlowFilter(0x000000,0.5,0,12,1,1,false,false)]; 


var workList:Array = new Array(
    { label: "All Work", data: "all" }, 
     { label: "Work1", data: "w1" }, 
     { label: "Work2", data: "w2" }, 
     { label: "Work3", data: "w3" } 
    ); 


var menu1:ComboBox = new ComboBox(); 
addChild(menu1); 

menu1.setStyle("upSkin", typeButton); 
menu1.setStyle("overSkin", typeButton); 
menu1.setStyle("downSkin", typeButton); 
menu1.setSize(109, 32); 

menu1.dropdown.setRendererStyle("upSkin", typeButton); 
menu1.dropdown.setRendererStyle("overSkin", typeButton); 
menu1.dropdown.setRendererStyle("downSkin", typeButton); 
menu1.dropdown.setSize(109, 32); 

menu1.textField.setStyle("textFormat", typeTextFormat); 
menu1.move(120, 0); 
menu1.prompt = "All Work"; 
menu1.dataProvider = new DataProvider(workList); 

Answer 1

好的，所以我找到了答案。它的一半！我现在有两个Sprite，两者形状相同，但称为typeButton和dropButton。这些都分别添加到父菜单1和menu1.dropdown。我不再得到消失的问题。所以这工作正常...有点...但点击左右一点后，我最终得到了参数错误：2025和我的有限的知识来对砖墙...

import fl.data.DataProvider; 
import fl.controls.ComboBox; 

var typeTextFormat:TextFormat = new TextFormat(); 
typeTextFormat.color = 0xFFCC00; 
typeTextFormat.size = 11; 
typeTextFormat.font = "Verdana"; 

var menu1:ComboBox = new ComboBox(); 
addChild(menu1); 

var typeButton:Sprite = new Sprite(); 
menu1.addChild(typeButton); 
typeButton.graphics.beginFill(0x000000); 
typeButton.graphics.drawRect(0, 0, 109, 34); 
typeButton.graphics.endFill(); 
typeButton.alpha = 0.75; 
typeButton.filters = [new DropShadowFilter(3,120,0x000000,0.5,0,0,1,1,false,false,false)]; 

var dropButton:Sprite = new Sprite(); 
menu1.dropdown.addChild(dropButton); 
dropButton.graphics.beginFill(0x000000); 
dropButton.graphics.drawRect(0, 0, 109, 34); 
dropButton.graphics.endFill(); 
dropButton.alpha = 0.75; 
dropButton.filters = [new DropShadowFilter(3,120,0x000000,0.5,0,0,1,1,false,false,false)]; 

menu1.setStyle("upSkin", typeButton); 
menu1.setStyle("overSkin", typeButton); 
menu1.setStyle("downSkin", typeButton); 
menu1.setSize(109, 34); 

menu1.dropdown.setRendererStyle("upSkin", dropButton); 
menu1.dropdown.setRendererStyle("overSkin", dropButton); 
menu1.dropdown.setRendererStyle("downSkin", dropButton); 
menu1.dropdown.setSize(109, 34); 

menu1.textField.setStyle("textFormat", typeTextFormat); 
menu1.dropdown.setRendererStyle("textFormat", typeTextFormat); 
menu1.move(120, 0); 
menu1.prompt = "All Work"; 
var dp:DataProvider = new DataProvider(); 
dp.addItem({ label: "All Work", data: "all" }); 
dp.addItem({ label: "Work1", data: "w1" }); 
dp.addItem({ label: "Work2", data: "w2" }); 
dp.addItem({ label: "Work3", data: "w3" }); 
menu1.dataProvider = dp; 

Answer 2

var dp:DataProvider = new DataProvider(); 
dp.addItem({ label: "All Work", data: "all" }); 
dp.addItem({ label: "Work1", data: "w1" }); 
dp.addItem({ label: "Work2", data: "w2" }); 
dp.addItem({ label: "Work3", data: "w3" }); 

menu1.dataProvider = dp;

menu1.setStyle("upSkin", typeButton);

menu1.dropdown.setSize(109, 32);

dp.addItem({ label: "All Work", data: "all" }); 
dp.addItem({ label: "Work1", data: "w1" }); 
dp.addItem({ label: "Work2", data: "w2" }); 
dp.addItem({ label: "Work3", data: "w3" }); 
menu1.dataProvider = dp;

好，
工作代码现在，我看你是有什么问题。
看来你的问题是与以下行

menu1.dropdown.setRendererStyle("upSkin", typeButton); 
menu1.dropdown.setRendererStyle("overSkin", typeButton); 
menu1.dropdown.setRendererStyle("downSkin", typeButton); 

显然，组合框的下拉列表是基于，因此使用项目渲染器。
所以你必须通过渲染器设置皮肤。

comboBox.dropdown.itemRenderer = "someItemRender.as"; 

我也跑过这个site.但是，我无法得到它的工作，但这个想法似乎是固体。
