How can i tell if a textfield is blank?
i've tried using

it works ok if no key has been pressed, but if the space bar has been pressed the length would be greater than 1 but the text field would still be blank.
Any suggestions would be appreciated

Try trimming the String after you call the getText() method, like this:

Or
if (textfield.getText().trim().equals("")){//do something}
}
