Setting the miter limit on a Path stroke in Flex 4

The following example shows how you can set the miter limit on a Flex 4 Path stroke by setting the miterLimit property on a stroke object.

Full code after the jump.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.

For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

            <FormItem label="miterLimit:">

                        value="0"

        <Path id="path" data="{pathData}">
            <stroke>
                <SolidColorStroke id="pathStroke"
                        joints="miter"
                        miterLimit="{slider.value}"
                        color="red"
                        weight="40" />
            </stroke>
        </Path>
        <Path data="{pathData}">
            <stroke>
                <SolidColorStroke
                        color="black"
                        weight="1" />
            </stroke>
        </Path>
    </Graphic>

</Application>

You can also set the miterLimit property using ActionScript, as seen in the following example:

    <Script>
        <![CDATA[
            import mx.events.SliderEvent;

            private function slider_change(evt:SliderEvent):void {
                pathStroke.miterLimit = evt.value;
            }
        ]]>
    </Script>

                        minimum="0"
                        maximum="10"
                        value="0"
                        tickInterval="1"
                        liveDragging="true"
                        change="slider_change(event);" />
            </FormItem>
        </Form>
    </ApplicationControlBar>

    <Graphic>
        <Path id="path" data="{pathData}">
            <stroke>
                <SolidColorStroke id="pathStroke"

                        weight="40" />
            </stroke>
        </Path>
        <Path data="{pathData}">
            <stroke>
                <SolidColorStroke
                        color="black"
                        weight="1" />
            </stroke>
        </Path>
    </Graphic>

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.
