Degrafa 贝塞尔样条线将数据绑定到字符串

发布于 2024-07-22 17:38:33 字数 900 浏览 10 评论 0原文

我想通过以下代码将贝塞尔样条线插入我的画布：

<mx:Canvas 
id="graphCanvas" 
width="100%" 
height="100%" 
preinitialize="preInit()"
/>
<BezierSpline id="mySpline" graphicsTarget="{[graphCanvas]}"  data="points"

verticalCenter =“0”horizontalCenter =“0” >

点是我在 preInit() 方法中初始化的字符串

[Bindable]public var points : String;
private function preInit() : void {
        points = "200,100 200,300 100,300 300,500 500,300 400,300 400,100";
    }

但是当我现在构建项目时，画布上没有绘制样条线，而直接将数据集成到 mxml 中

<BezierSpline id="mySpline" graphicsTarget="{[graphCanvas]}"  data="200,100 200,300 100,300 300,500 500,300 400,300 400,100"

verticalCenter =“0”horizontalCenter =“0” >

有人能帮我吗？我需要动态更改样条线的数据。也欢迎以编程方式处理它的答案，因为我真的不知道如何通过代码在画布上重绘样条线（不知道如何使用样条线的 draw() 方法）。

I want to insert a bezier spline into my Canvas by this code

<mx:Canvas 
id="graphCanvas" 
width="100%" 
height="100%" 
preinitialize="preInit()"
/>
<BezierSpline id="mySpline" graphicsTarget="{[graphCanvas]}"  data="points"

verticalCenter="0" horizontalCenter="0"
>

points is a string I initialize in the preInit() method

[Bindable]public var points : String;
private function preInit() : void {
        points = "200,100 200,300 100,300 300,500 500,300 400,300 400,100";
    }

But when I now build the project no spline is drawn on my canvas whereas directly integrating the data in the mxml works

<BezierSpline id="mySpline" graphicsTarget="{[graphCanvas]}"  data="200,100 200,300 100,300 300,500 500,300 400,300 400,100"

verticalCenter="0" horizontalCenter="0"
>

Can someone help me? I need to dynamically change the data of the spline. Also answers that handle it programmatically are welcome as I do not really know how to redraw the spline on my canvas by code (don't know how to use the draw() method of the spline).

Thanks in advance

这段代码对我有用：

[Bindable]
private var points:String;
private function preinit ():void
{
    points = "200,100 200,300 100,300 300,500 500,300 400,300 400,100";
}

<degrafa:BezierSpline id="mySpline" graphicsTarget="{[graphCanvas]}" data="{points}">
    <degrafa:stroke>
        <degrafa:SolidStroke weight="2" color="#0000FF"/>
    </degrafa:stroke>
</degrafa:BezierSpline>

This code works for me:

[Bindable]
private var points:String;
private function preinit ():void
{
    points = "200,100 200,300 100,300 300,500 500,300 400,300 400,100";
}

<degrafa:BezierSpline id="mySpline" graphicsTarget="{[graphCanvas]}" data="{points}">
    <degrafa:stroke>
        <degrafa:SolidStroke weight="2" color="#0000FF"/>
    </degrafa:stroke>
</degrafa:BezierSpline>
