Detecting RTL and LTR TLF text

[Jim Wiley]

Hi All,

I have set RTL in the preferences panel.

I need to test RTL and LTR 'direction' setting. It reports Null if it has not been explicitly set because it inherits the LTR.  I am trying to set LTR explicitly when I initialize the text and put it on the stage or at minimum, test for null and force it.

import flash.text.*;

import flash.text.TextFormat;

if (txtField.direction == null) {
        trace("It traces Null");// It traces Null 
        txtField.direction = LTR;
}

RangeError: Property direction value LTR is out of range
        at flashx.textLayout.property::Property$/defaultErrorHandler()
        at flashx.textLayout.property::EnumStringProperty/setHelper()
        at flashx.textLayout.formats::TextLayoutFormatValueHolder/setCoreStyle()
        at flashx.textLayout.formats::TextLayoutFormatValueHolder/set direction()
        at flashx.textLayout.elements::FlowElement/set direction()
        at fl.text::TLFTextField/set direction()
        at Code::Page1/textOverFlow()
        at Code::Page1/_Topic()
        at Code::Page1()

I have tried to add this:
import flashx.textLayout.formats;

Then it reports:

Page1.as, Line 16 1172: Definition flashx.textLayout:formats could not be found.

It is a constant, you must prefix it with the class or pass it as a string.

e.g.

txtField.direction = "rtl"; // string

or, better:

import flashx.textLayout.formats;

txtField.direction = Direction.RTL; // const

thanks Sinious,

It got me real close. The first wouldn't work. I tried many variation on that one. Before and after your solid input.

The second/better did work when importing the .Direction too.

Was:

import flashx.textLayout.formats;

S/B:

import flashx.textLayout.formats.Directions;

Ah you're right. I'm glad you imported Direction and use the CONST RTL over the string version. Much better future proofing.

You're welcome and glad you got it fixed. Good luck!

Follow-up

I implemented it and I wanted to point out a few typos - details.

tempCC.ccTextMC.Label - is the text field. The If statement below is testing if the language is Arabic (ar) or Hebrew (he)

Code

import flashx.textLayout.formats.Direction;

    if (Lang ==  "ar" || Lang ==  "he") {

     tempCC.ccTextMC.Label.direction = Direction.RTL;

    }
