JAVA SET ICON TO BUTTON HOW TO
Refer to Swing Components Supporting Action for more details, and you can find more information in How to Use Actions, a section in The Java Tutorial. Using an Action with a button has many benefits beyond directly configuring a button. JFrame f = new JFrame("Add Image Icon to JButton") Buttons can be configured, and to some degree controlled, by Action s.
Example 1: Add Image Icon to JButton import javax.swing.* In the above code, we have defined the icon for the btn button. Icon icon = new ImageIcon("C:\\image.jpg") In the example below, we create a button in which we add an icon with the class Icon. To add an icon to a button, use the class Icon, which will allow you to add an image to a button. If (scaledDimension.In this tutorial, we are going to see how to add image Icon to JButton in Java Swing. Center the scaled image into the BufferedImage scaledAndCenteredImage = new (_width, _height, .TRANSLUCENT) ĭimension scaledDimension = getScaledDimension( new Dimension(_icon.getImage().getWidth(null), _icon.getImage().getHeight(null)), new Dimension(_width, _height)) Rescale the image such that it maintains its aspect ratio but fits within the IconLabel size Public IconLabel(Image image, int width, int height)
Public IconLabel(ImageIcon icon, int width, int height) In this JLabel-extending class, the real tricks are to override getPreferredSize and the paintComponent methods, where I do the image resizing. The getScaledDimension is taken from that URL, and it does a better job of explaining how it resizes an image and maintains its aspect ratio. That way, you can pre-determine how big of a space you want your image to take without compromising its aspect ratio. For added bonus (and for satisfying my OCD), I have pieced together some logic that also scales the image to within a certain size, maintaining its aspect ratio (i.e., I used ). You may not need the whole IconLabel class, but it does implement the resize technique mentioned above. In the project I am working on, I have been using a modified JLabel to use a resized icon. In this situation, it looks like you do actually need a resized image. All of the posts I have read elsewhere recommend using the BufferedImage/Graphics.drawImage approach. Now recreate the IconImage with the new buffered image:
JAVA SET ICON TO BUTTON CODE
(The code above may be incorrect - check the docs) G.drawImage(img, 0, 0, WIDTH, HEIGHT, null) Then blit the icon image to the buffered image, and resize it as you do so: Now create a buffered image the same size as the image:īufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB) Then use getImage() to grab the image from the ImageIcon: Make sure the reference you create is an ImageIcon reference. ImageIcon icon = new ImageIcon("whatever.jpg") You load your image straight into the ImageIcon using the constructor that takes a file name as an argument like: Daniel Searson wrote:Ok, here's one way of doing it.
