How to check if JTextField is NOT editable

Question

Sorry if this is a simple question but I'm not entirely sure how I check if a JTextField is not editable?

I know that to check if it is editable, you just use

JTextField.isEditable();

but how do I check if it is not?

Thanks

Answer 1

Accordingly to Java docs ( https://docs.oracle.com/javase/7/docs/api/javax/swing/text/JTextComponent.html#isEditable%28%29 ), isEditable:

Returns the boolean indicating whether this TextComponent is editable or not.

So, I guess you could just:

if (yourInstance.isEditable() == false) {
    // Your action here
}

Or even:

if (!yourInstance.isEditable()) {
    // Your action here
}

Use the logical complement operator (NOT):

if ( !textField.isEditable()){
    .
    .
    .
}
