Flex 4: Changing the “displayAsPassword” default character
Today I ran into a situation where I wanted to display my password characters as a bullet versus the default asterisk (“*”).
I thought this would be pretty simple to do but realized after digging through the Flex 4 SDK that there was no public property I could set to change this. I tried hacking commitProperties and a couple of other methods but came up short in those areas as well until I found the exact spot in the Flex libraries where this character was defined:
RichEditableText.as (line 679)
1 2 3 4 | /** * @private */ mx_internal var passwordChar:String = "*"; |
A-ha! I see here that it’s prefixed with the “mx_internal” namespace and I remembered from other examples around the web that you can easily tap into that namespace and modify properties not normally meant to be modified.
Luckily, I had already extended the TextInput class for various other reasons and decided to add an event listener for the CREATION_COMPLETE lifecycle event of the component. This was added in the constructor:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | import mx.core.mx_internal; /** * Constructor */ public function myTextInput() { super(); this.addEventListener( FlexEvent.CREATION_COMPLETE, onCreationComplete ); } private function onCreationComplete( event : FlexEvent ) : void { //change internal passwordChar to a bullet versus an asterisk this.textDisplay.mx_internal::passwordChar = "●"; } |
…and voila! By tapping into the mx_internal namespace, I found I could modify the normally private variable “passwordChar” and set it to something I preferred better (in this case, the bullet point used in some sites like Twitter).
Hope this helps someone!

and tested to see if it can survive a 40 foot drop, just so she can be a youtube sensation. My apple ipad
is now broken and she has 83 views. I know this is completely off topic but I had to share it with
someone!
Excellent hours, salaries, ond conditions, and perk.

A Michigan man has created a rocking Christmas display at
his home that lights up to the tune of hit songs.
Footage shows Kyle Bostick’s Garden City property decked out
in lights synced to Aaron Gage’s version of Deck The Halls being
played to the tune of Black Sabbath’s heavy metal War Pigs.
In the clip, candy canes are seen jumping like high hats,
snow flakes flashing to the guitar riff and a computer-generated Christmas tree
is belting out the words.
The fascinating light show, produced by Kyle, is
now in its second year, and features rock hits like War Pigs to give passersby ‘the wow
factor’.
The Bostick family’s display is put on for charity but has proved so popular they have won Garden City’s annual holiday lights contest.
Kyle has run lights throughout the last two years including on 4th of July and Valentine’s Day after starting out last Halloween, his
wife Christina’s favourite holiday.

‘It started off with my wife wanting to do
something crazy for Halloween, so last year went all out and put on a light
show,’ Kyle explained.
‘We had no intentions of doing Christmas, but after we received messages
from hundreds of people saying “I can’t wait to see what you do for Christmas,” we thought
“ahh damn, now we’ve got to do something for Christmas”.’
Kyle, who has a background in computers, says the show is very time-consuming to put
on, as it takes ‘around 10 hours of programming for one minute of song’.

He has also set his dazzling lights to other hits, including Sia’s Candy Cane Lane, the Star Wars Theme, and Metallica’s Enter Sandman.
During last year’s Christmas light show, the Bosticks raised over $4,
500 for the Detroit Animal Welfare Group.
Each new show now raises money for another charity.
The family went a step further with a 4th of July show this year, organising an ice cream
truck to stop for kids and even integrating fireworks into the performance.
