在actionscript中创建一个带有图标的按钮

Question

我想使用Actionscript动态创建带有图标的按钮.

我试过这个,没有成功:

var closeButton = new Button();
closeButton.setStyle("icon", "@Embed(source='images/closeWindowUp.png");

Answer 1

我找到了一个适合我的答案.在我的.mxml文件中,我将为我将使用的图标创建类:

// Classes for icons
[Embed(source='images/closeWindowUp.png')]
public static var CloseWindowUp:Class;
[Embed(source='/images/Down_Up.png')]
public static var Down_Up:Class;
[Embed(source='/images/Up_Up.png')]
public static var Up_Up:Class;

在我的应用程序的Actionscript部分中,我在动态创建按钮时使用这些类:

var buttonHBox:HBox = new HBox();
var closeButton:Button = new Button();
var upButton:Button = new Button();
var downButton:Button = new Button();

closeButton.setStyle("icon", SimpleWLM.CloseWindowUp);
buttonHBox.addChild(closeButton);

upButton.setStyle("icon", SimpleWLM.Up_Up);
buttonHBox.addChild(upButton);

downButton.setStyle("icon", SimpleWLM.Down_Up);
buttonHBox.addChild(downButton);
