缩小范围 - 排除一些孩子？ [英] Scaling in flex - exclude some children?

问题描述

我正在尝试在flex中构建一个webmap应用程序。
为ths，'有一个fxg文件，代表地图。
它在
中也有一些元素，如POI，文本等等。
我用scaleX和scaleY缩放，这对地图很好用。

但问题是：ALL childen缩放。我不想要这个他们应该保持在地图上相同的位置。

将某些代码
作为函数

 < fx：脚本> 
 
<！[CDATA [
 import mx.skins.Border; 
 [Bindable] 
 public var hoehe：Number = 1; 
 [Bindable] 
 public var breite：Number = 1; 
 
 protected function zoom_changeHandler（event：Event）：void 
 {
 hoehe = zoom.value; 
 breite = zoom.value; 
} 
]]> 
< / fx：脚本> 
  

和

 code>< s：Scroller width =100％height =100％baseline =10> 
 
< s：Group scaleX ={breite}scaleY ={hoehe}id =mapView> <！ -  zum zoomen  - > 
 
< s：Group horizo​​ntalCenter =0> <！ - Enthältalle Objekte  - > 
< images：karte id =kartePanelheight =630width =430/> 
< images：akw id =akw1scaleX =0.2scaleY =0.2top =158left =190/> 
< components：akwView x =154y =131resizeMode =scale> 
< / components：akwView> 
< / s：组> 
< / s：组> 
< / s：Scroller> 
  

componentsLakwView包含一些标签等，这不应该调整大小？

解决方案

您可以对具有反值的那些孩子进行否定缩放 - 例如，如果将缩放2.0应用于父项，则将1 / 2.0 = 0.5比例应用于这些孩子，他们的大小将不变。

i'm trying to build a webmap application in flex. for ths, 've got a fxg-file which represents the maps. it's in a also there are some elements, like POIs, text et cetera in this group. i zoom the with scaleX and scaleY, this works just fine for the map.

but the problem is: ALL childen zoom also. i don't want this. they should stay the same place on the map and the same size.

heres some code the as function

<fx:Script>

    <![CDATA[
        import mx.skins.Border; 
        [Bindable]
        public var hoehe:Number = 1;
        [Bindable]
        public var breite:Number = 1;

        protected function zoom_changeHandler(event:Event):void
        {
            hoehe = zoom.value;
            breite =  zoom.value;
        }
    ]]>
</fx:Script> 

and the

    <s:Scroller width="100%" height="100%"   baseline="10">

<s:Group scaleX="{breite}" scaleY="{hoehe}"  id="mapView" > <!-- zum zoomen -->

    <s:Group horizontalCenter="0" > <!-- Enthält alle Objekte -->
    <images:karte  id="kartePanel" height="630" width="430" />
    <images:akw   id="akw1" scaleX="0.2" scaleY="0.2" top="158" left="190" />       
    <components:akwView x="154" y="131" resizeMode="scale">
    </components:akwView>
    </s:Group>
</s:Group>
</s:Scroller>

componentsLakwView contains some labels etc. this should not be resized?

解决方案

You can negate zoom for those children with inverse value - for example, if you apply zoom 2.0 to parent, apply 1/2.0 = 0.5 scale to those children, and their size will be constant.
