I'm trying to code a JButton in Netbeans and I want to display an image from my local disk when the button is clicked. This button is inside a panel.
How to display an image when I click a button?

As you can see in this gif:
when I click an icon on the navbar the icon and text background appear, also, if I long click it will appear a text too, how can I remove the icon and text background and the long click text?
Im trying to make a simple memory game where if two buttons rather the icons on them match, the score increases. Im quite stuck on how to make the icon on the button show after it has been clicked. So far I have used:
public class NextFrame extends javax.swing.JFrame {
/**
* Creates new form NextFrame
*/
public NextFrame() {
initComponents();
btnCard1.setIcon(null);
btnCard2.setIcon(null);
btnCard3.setIcon(null);
btnCard4.setIcon(null);
btnCard5.setIcon(null);
btnCard6.setIcon(null);
//list goes on....
}
private void btnCard1ActionPerformed(java.awt.event.ActionEvent evt) {
//Not sure what goes here....
}
Using java Swing I have placed my icons within the JButtons. So only when a user clicks on it I want the selected button to display the icon. By setting the property of the button to pressedIcon only shows the icon when I press and click on the button. How do I make it so that the icon is rather fixed as I click once.
Also since my images are already there in GUI and I've only just set each button to null in the beginning, is there a method to just change from null to the actual icon.
You're overthinking things.
You know how to create an icon and set it as a button icon, yes?
Image image = new ImageIcon("C:\\some_image.png");
JButton myButton = new JButton(imageIcon);
What if you actually created two icons like so:
Image image1 = ImageIcon(getClass().getResource("real_image.png")
Image image2 = ImageIcon(getClass().getResource("blank_image.png")
When you create the button, use the blank image, which is the same size as the real image, but doesn't contain the actual image. The reason for using a blank image rather than setting the image to null is because a button without an image may actually change size once you add the image, which can potentially mess with your layout.
JButton myButton = new JButton(image2);
Now in your ActionPerformed handler which runs when the user clicks the button, you set the real image on the button:
myButton.setIcon(image1);
I created a JButton in java and I set a png logo icon to it. The icon is round with transparent background and I want that the button is activated only when I click on the image and not on the transparent background. How can I do it?
I want to change the color of the button.
When you press the button it will show for you to choose red, blue, green and when you choose one color. This color will be shown on the button that was first pressed.
I read problem ----> Click Button and change background color of another button
But I not understand.
Well for this you can create an alert dialog with buttons
And in the buttons you have to add.
buttunname.setBackgroundColor(thecolor);
And then if the button is clicked the background of the button will be changed after that to the color that you choose
I am Creating a ImageViews dynamically now i need to display pop up menu if click the ImageView.
ex: In that pop up i will add download. If i click that download button respective Image should download.
I'm not very sure about putting a button on an imageview...take a look at this answer:
Put a button over an ImageView
As for making a popup appear on button click, use dialogfragments.
