POUpdating swing components correctly?
text
Body
copied!<p>I'm new to swing, any help appreciated.</p> <p>In this piece of code I'm turning a card over face up, if it turns out that they don't match I want them to turn back face down again.</p> <p>At the moment what is happening: 1. when clicked the first card turns over 2. when a second card is clicked either of two things happen (a) if they are the same they both stay up which is what I want (b) if they are not the same I never see the 2nd card at all as it immediately re-displays the back of the card (and the back of the previous card also as defined in my method).</p> <p>I thought putting in the sleep timer might keep the 2nd card displayed for a period of time before turning back over but it does not.</p> <p>I attempted to use contentPane.revalidate(); & contentPane.repaint(); but it doesn't change anything.</p> <p>I have put in some console outputs:</p> <pre><code>Console output: Card: 0 set Card: 6 set Sleeping now Card: 6 unset Card: 0 unset </code></pre> <p>Above is the resulting console output when clicking two card which do not match</p> <pre><code>@Override public void actionPerformed(ActionEvent e) { String buttonPressed = e.getActionCommand(); int pos = Integer.valueOf(buttonPressed); action = Control.model.ReceiveCardsTurned(pos); keypadArray[pos].setIcon(myIcons[pos]); System.out.println("Card: "+pos+" set"); currentTime.setText("" + Control.model.time); currentScore.setText("" + Control.model.score); //contentPane.revalidate(); //contentPane.repaint(); if(Control.model.twoCardsTurned == false) { if (action == "unturn") { System.out.println("Sleeping now"); try { Thread.sleep(1000); } catch (InterruptedException e1) { e1.printStackTrace(); } keypadArray[pos].setIcon(back); keypadArray[Control.model.lastCard].setIcon(back); System.out.println("Card: "+pos+" unset"); System.out.println("Card: "+Control.model.lastCard+" unset"); } } } </code></pre>
