Examples of javax.swing.InputVerifier.shouldYieldFocus()

javax.swing.InputVerifier.shouldYieldFocus()

Calls verify(input) to ensure that the input is valid. This method can have side effects. In particular, this method is called when the user attempts to advance focus out of the argument component into another Swing component in this window. If this method returns true, then the focus is transfered normally; if it returns false, then the focus remains in the argument component. @param input the JComponent to verify @return true when valid, false when invalid @see JComponent#setInputVerifier @see JComponent#getInputVerifier
