textfield

问题 I'm working on a TextField and just get a strange "extra border" I can't identify where it is comming from.

问题 In actionscript 3, my TextField has : CSS styling embedded fonts textAlign : CENTER autoSize : CENTER ... when italics are used the very right character gets slightly cut off (specially caps).

Then do this little trick

问题 I know virtually nothing about Javascript.

The code below, is the code I

问题 We are creating an user's editing data page, so the textfield already comes filled with the user data and users can change and save it... The problem is that when I start to enter character into textfield, the cursor get lost, every character that I enter (from the device keyboard), the cursor goes to the first character... and if I remove the controller with my initial value, it works fine, but then I can not have my textfield filled with the users data.
