Assassinating jumpy htmlText hyperlinks
UPDATE: Read this great tutorial on styling the HTML text field
I read quite recently that people are still swearing Flash jumpy hyperlinks in htmlText with Anti-aliased for readability option turned on. What are they talking about? – here's the example.
Roll over and out the links in the left column and carefully observe what happens to the text. Pretty bad stuff.
Fortunately, there is a perfect workaround discovered by Jonnie Hallman aka Destroy Today, but not everybody knows about it yet. So, (to save the world), I wrote a simple TextField wrapper class that automatically deals with the issue, additionally it also fixes another annoying bug – selectable code>TextField scrolls one line on text select – when you click and drag down the mouse while selecting the text, the content scrolls vertically! (and it shouldn't as the text height is the same as the box height, so there's nothing to scroll)
The fixed TextField is presented in the right column – again, try rollover the links.
How does the fix work then?
Basically, after setting the htmlText property, store the height of the TextField, then set autoSize to NONE. That will lock it, so no no more jumping is happening. It is all done at one go by overriding htmlText setter method.
override public function set htmlText(value:String):void
{
autoSize = TextFieldAutoSize.LEFT;
super.htmlText = value;
recordedHeight = height;
autoSize = TextFieldAutoSize.NONE;
// adding extra height will prevent "vertical scroll on text select" bug
// the extra height value should be just bigger than the default leading
height = recordedHeight + getTextFormat().leading + 1;
}
Additionally, we're adding few pixels extra the TextField default leading value plus 1 to the height there (discovered by Luke Sturgeon), it will prevent "vertical scroll on text select" bug described above.
How should I apply this fix to my broken TextField?
By creating a FixedTextField instance instead, exactly the same way as you would instantiate an ordinary TextField:
var textTF:FixedTextField = new FixedTextField();
Alternatively, you could clone an existing TextField by referencing to it:
var textFieldFixed:FixedTextField = new FixedTextField(someOtherTextFieldToClonePropertiesFrom);
In fact, you can even attach the TextField stored in the Flash IDE library (obviously wrapped up in a MovieClip symbol) – I wrote a separate blog post on that matter.
