Re: [flexcoders] Override private ComboBox function

[Warren]

Just a followup.  I got the combobox re-written to optionally force direction 
of the dropdown menu. I ended up following Tracy Spratt's suggestion by copying 
the code directly into a new component class (along with the inclusions).

Thank you to all that replied!

  Well, I gave it a go with no luck.  Too many inaccessible properties (like 
_showingDropdown ).  Sigh

    You can simply override the open and close functions as well. (public 
override function open():void{ ... ).

      Very good idea.  I didn't think to look for the calling functions. How do 
I handle the two public functions (Open and Close)?  Can I simply create new 
functions for them in my class?

        Hi Warren,

        While the displayDropdown method is private, the methods which call it 
(downArrowButton_buttonDownHandler & keyDownHandler) are both protected.
        You can override these 2 methods and have them call a new private 
method which can mimic the behaviour of displayDropdown along with the new 
functionality you want to add.

        Hope this helps,

        Tibor.

          I'm want to make a ComboBox on which I can force the dropdown menu to 
go up or down.  It should be a simple matter of adding a variable and changing 
the way the displayDropdown method works.  I tried extending the ComboBox and 
overriding the displayDropdown method but I can't do that since the method is 
private.

          How can I do this with my own class ?  I feel like I'm missing 
something basic here.....  

          I'm using Flex 3.2.0 SDK

          Thanks!
