How to use Look&Feel in Swing
Editor to share with you how to use Look&Feel in Swing, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
Today, I used Swing to do a login interface that imitates QQ2009, using the open source Look&Feel (Substance). I encountered some problems and learned some skills in the process of using it. Substance (https://substance.dev.java.net) has a lot of looks to choose from, and they are all beautiful, and it also provides a powerful API for developers to use. Substance has now developed to the 5.2RC version. At first, I used version 5.1, but I found some bug in the process of using it. When I used the watermarking feature provided in Substance, there were a lot of exceptions. This bug was not available in 5.0. later, I downloaded the 5.2RC version of *, which has been solved in version 5.2.
* question: how to use Look&Feel completely?
This is a piece of cake for Swing veterans, but it is difficult for Swing beginners, because many of the tutorials they see using look&feel are like this:
UIManager.setLookAndFeel (new SubstanceOfficeBlue2007LookAndFeel ())
Or this:
Try {UIManager.setLookAndFeel ("org.jvnet.substance.skin.SubstanceRavenGraphiteLookAndFeel");} catch (Exception e) {System.out.println ("SubstanceRavenGraphite failed to initialize");}
Or I'm too lame. In short, I don't know how to change the title bar until I seriously learn the look and feel of Swing.
It only takes one sentence to change the title bar, which is to add this sentence to the main method:
JFrame.setDefaultLookAndFeelDecorated (true)
The second question is, how to add a watermark or background to an application?
The official documentation says very little, and there are no specific examples of how to use it. Later, I downloaded the source code of Substance to find out how to use it.
The following is a core code I wrote in the main method with reference to the official source code
JFrame.setDefaultLookAndFeelDecorated (true)
JDialog.setDefaultLookAndFeelDecorated (true)
Try {
SubstanceImageWatermark watermark = new SubstanceImageWatermark
(LoginFrame. Class .getResourceAsStream ("/ demo/001.jpg"))
Watermark.setKind (ImageWatermarkKind.SCREEN_CENTER_SCALE)
SubstanceSkin skin = new OfficeBlue2007Skin () .withWatermark (watermark)
/ / initialize the skin with watermark
UIManager.setLookAndFeel (new SubstanceOfficeBlue2007LookAndFeel ())
SubstanceLookAndFeel.setSkin (skin); / / set skin
}
Catch (UnsupportedLookAndFeelException ex) {
Logger.getLogger (LoginFrame. Class. GetName () .log (Level.SEVERE, null, ex)
}
