Get User Input

[genleo]

Hi all,
I'd like to validate text input from user, the length of a key for example. Is there a way to do it from InstallAnywhere directly or should I implement a custom panel?

Thanks in advance.

You are using IA 2008 or an earlier version?

You can use a custom panel if you want to.

You should also be able to evaluate a rule after your original panel with either a custom rule or a regular expression.

I'm using IA 2008.
I've implemented a custom panel but I'm not able to add action listener (is it possible???) to the Next button of Installer Frame.
I tried to add a jButton to custom panel and I can get the input text from the user correctly... So, how can I add a listener to default Next button?

Thanks

Yes you can:

Container guiContainer = ((GUIAccess) ccpp.getService(GUIAccess.class)).getFrame();
if (guiContainer instanceof JFrame) {
	guiContainer = (Container) ((JFrame) guiContainer).getContentPane().getComponent(0);
	JButton guiJButton = (JButton) ((Container) guiContainer.getComponent(3)).getComponent(2);
	guiJButton.addActionListener(new NextListener(guiContainer));
}

Best Regards,
Yves

Ok, in which method should I put this code? And should I create a new NextListener class?

Thanks for your help!

When do you want to validate your text entry? I find it much easier to validate when the user clicks next. I put the validation code in the okToContinue() method of the CustomCodePanel. Then if the input is incorrect, I display a dialog explaining and have that method return false and make the user try again.

Thanks a lot... It works correctly!

i tried the same thing to get the user input..
i have:
1)custom panel with oktocontinue method.. which checks the correctness of input.. and set the $var$ variable true/false..
2) then according to $var$.. i display error message dialog saying input is wrong 3)But after message appears and user clicks OK.. Just blank white screen comes without anything in it.. (the panel is not refreshed somehow 😞 )

But if i minimize and then maximize the installer window .. it appears again !..

please help !

thank you
