Textfield Uppercase

[cblanken...@gmail.com]

If you are experiencing an issue please mention the full platform your issue applies to:
IDE: NetBeans
Desktop OS
Simulator
Device

I need to allow the user to use alpha, numeric, and symbols but need to uppercase any provided alpha values to uppercase.

1. is there a way to force a textfield to uppercase regardless of if it is being entered in as lowercase? if so examples?

2. is there a way for a textfield on loss of focus to update the data that has changed to uppercase? also if so examples?

Thank you.

Hi,

myTextfield.setInputMode("ABC");

could help, but you can't change textfield value to anything else as you type, it will trigger a stackOverflowException. 

You can add a doneListener to your textfield to change it's value to Caps after input is completed.

have tried setInputMode("ABC") that does not appear to work on my device. doneListener will only work on supported platforms.

Hi,
in the action event for the text field just invoke tf.setText(tf.getText().toUpperCase());

The input mode code is only relevant to older devices that work with lightweight input.

As Shai suggested, actionEvent got triggered once the Textfield loses focus. You can invoke it as follows:

        txtChangeToUpper.addActionListener(new ActionListener() {

            @Override

            public void actionPerformed(ActionEvent evt) {

                txtChangeToUpper.setText(txtChangeToUpper.getText().toUpperCase());

            }

        });
