Hey everyone,

I wanted to know, what is the status of undocumented API's on the blackberry?

I want to use TextField.autoSelectFullText(). It works well, but isnt documented.

What are the risks? is there an alternative to using this message to select all the contents of a TextField?

Undocumented methods should not be used.  They can change or be removed at any time.

Can you describe what you are trying to accomplish?  With that we may be able to provide an alternative option.

i would guess that he wants to select all the text in a field

[MSohm]

This can be done by calling setCursorPostion(0), then calling the select method and passing in true and then calling setCursorPostion again and passing in the text length.

[omri]

like this?

fEditField.setCursorPosition(0);
fEditField.select(true);
fEditField.setCursorPosition(EditField.getTextLength());

because it dosnt work.

it just puts the cursor at the end.

I checked it now with just  fEditField.select(true); 

calling this method didnt enter select mode.

Yes that should work.  I tried it in the BlackBerry Simulator included in the version 4.5.0 BlackBerry JDE.  What version are you using?

[omri]

i use the eclipse plugin, JDE 4.3.

for backwords compatability reasons.

i have the JDE 4.6 Beta installed, Ill check if it works with that for me.

I tried it in the version 4.3.0 BlackBerry JDE and it worked there as well.  In my test, I was overriding the keyChar method of EditField to execute the same code if a specific key was pressed.

From where are you trying to call this code from?  Does the field have focus at the time (required to select)?

[omri]

I'm doing this within the constractor for my class.

Before calling it i call field.setFocus()

 fEditField= new EditField("Name: ", strName);

add(fEditField)

if (selectTitle)
{

    fEditField.setFocus()
    fEditField.setCursorPosition(0);
    fEditField.select(true);
    fEditField.setCursorPosition(fCardName.getTextLength());
    //fEditField.autoSelectFullText();
}

 and i tried on 4.6 beta and that didnt work too...

any idea?

First push the screen that contains the EditField, then perform your selectTitle code block.
