在一个混合的Flash IDE / Flex项目,我有一个文本字段,我想找回,它将与该文本字段相关的字体类对象。该文本字段住在这是在CS4 IDE中创建并加载到Flex SWF的SWF。
目前,我有code如果满足以下条件的作品:
字体出口在孩子SWF的库。 在该文本字段链接到导出的字体。 导出字体的名称是硬codeD父SWF。code如下:
fontClass = childSwf.loaderInfo.applicationDomain.getDefinition(CustomFont的)为类;
我真正想要做的就是不会要知道导出的字体的名称。相反,我要动态地抓住任何字体的类或类的名字从文本字段。
更妙的是得到班内置字体,而无需出口的能力。
FWIW,最终目标是抓住任意文本字段,并检查它是否包含字符,它的嵌入字体不能使用字体:: hasGlyphs表明()。然而,在子SWF的字体没有登记显示在字体:: enumerateFonts()。
解决方案您可以使用它 getTextFormat
功能的文本字段的字体名称。考虑 TXT
的文本框,然后
VAR格式:的TextFormat = txt.getTextFormat();
跟踪(format.font);
经过一番研究,我发现这个解决方案,它可能会解决这个问题。
进口API元素flash.text.TextField;
进口flash.text.TextFormat用于;
进口flash.utils.getQualifiedClassName;
进口flash.text.Font;
进口flash.display.Loader;
进口对象类型:flash.events.Event;
进口flash.net.URLRequest;
VAR字体:字体;
VAR TXT:文本字段;
VAR装载机:装载机=新的Loader();
loader.contentLoaderInfo.addEventListener(引发Event.COMPLETE,onLoaded);
loader.load(新的URLRequest(sub_fla.swf));
功能onLoaded(五:事件){
VAR CL:类= e.currentTarget.applicationDomain.getDefinition(CustomFont的)为类;
Font.registerFont(CL);
跟踪(CL);
TXT =新的TextField();
this.addChild(TXT);
txt.text =Moorthy;
变种格式:的TextFormat =新的TextFormat(); // = txt.getTextFormat();
字体=新CL();
format.font = font.fontName;
txt.setTextFormat(格式);
enumerateFonts();
}
功能enumerateFonts(){
VAR embeddedFonts:阵列= Font.enumerateFonts(假);
embeddedFonts.sortOn(的fontName,Array.CASEINSENSITIVE);
跟踪( - >中+ embeddedFonts.indexOf(txt.getTextFormat()字体)。);
对于(VAR我:= 0; I< embeddedFonts.length;我++){
字体= embeddedFonts [I]
跟踪(embeddedFonts [+ I +]:+ font.fontName +:+字体);
如果(txt.getTextFormat()。字体== font.fontName){
跟踪(我的字体类是'+的getQualifiedClassName(字体)+');
}
}
}
不要忘记注册的字体得到它在 enumerateFonts 列表。否则,它获取的默认字体类不是你的自定义类。
否则,您只需加一个变量的影片剪辑(其中文本字段放置)来保存字体类或字体类名。
例如:如果架
是谁包含文本字段的影片剪辑,然后用
holder.fontClass = CL
Font.registerFont
您可以通过
只检索Font类 txt.parent.fontClass
如果因此在这种方式不需要 enumerateFonts
的。
In a mixed Flash IDE/Flex project, I have a TextField and I want to retrieve the Font class object that's associated with that TextField. The TextField lives in a SWF that was created in the CS4 IDE and is loaded into a Flex SWF.
Currently, I have code that works if the following criteria are met:
The font is exported in the child SWF's library. The TextField is linked to the exported font. The name of the exported font is hard-coded in the parent SWF.Code as follows:
fontClass = childSwf.loaderInfo.applicationDomain.getDefinition("CustomFont") as Class;
What I really want to do is not have to know the name of the exported font. Instead, I want to grab either the font's Class or the Class name dynamically from the TextField.
Even better would be the ability to get the Class for built-in fonts without requiring the export.
FWIW, the end goal is to grab any arbitrary TextField and check if it contains characters that its embedded font can't show using Font::hasGlyphs(). However, fonts in child SWFs aren't registered to show up in Font::enumerateFonts().
解决方案you can get the text field font name by using getTextFormat
function of it. Consider txt
is the textfield, then
var format:TextFormat = txt.getTextFormat();
trace(format.font);
After some research, I found this solution and it might solve the problem.
import flash.text.TextField;
import flash.text.TextFormat;
import flash.utils.getQualifiedClassName;
import flash.text.Font;
import flash.display.Loader;
import flash.events.Event;
import flash.net.URLRequest;
var font:Font;
var txt:TextField;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaded);
loader.load(new URLRequest("sub_fla.swf"));
function onLoaded(e:Event){
var cl:Class = e.currentTarget.applicationDomain.getDefinition("CustomFont") as Class;
Font.registerFont(cl);
trace(cl);
txt = new TextField();
this.addChild(txt);
txt.text = "Moorthy";
var format:TextFormat = new TextFormat();// = txt.getTextFormat();
font = new cl();
format.font = font.fontName;
txt.setTextFormat(format);
enumerateFonts();
}
function enumerateFonts(){
var embeddedFonts:Array = Font.enumerateFonts(false);
embeddedFonts.sortOn("fontName", Array.CASEINSENSITIVE);
trace("---->"+embeddedFonts.indexOf(txt.getTextFormat().font));
for(var i:int = 0;i<embeddedFonts.length;i++){
font = embeddedFonts[i];
trace("embeddedFonts["+i+"]:"+font.fontName+":"+font);
if(txt.getTextFormat().font == font.fontName){
trace("My font class is '"+getQualifiedClassName(font) +"'");
}
}
}
Don't forget to register the font to get it in the enumerateFonts
list. Otherwise it fetches the default font class not your custom class.
Or else, you can simply add a variable to the movieclip (in which the text field is placed) to hold the font class or font class name.
Eg: If holder
is the movieclip who contains the textfield, then use
holder.fontClass = cl
instead of
Font.registerFont
and you can simply retrieve the font class by
txt.parent.fontClass
If so there is no need of enumerateFonts
in this way.
