Nimbus Look&Feel 刷新 Painter

Question

I'm using the Nimbus look & feel in my swing application.

I set the primary and secondary properties of the UIDefaults of the look & feel. The colors are right. Now i have the problem, that the painter of the components use the colors, which were defined before updating the color theme.

Is there a way, to update the painters of all components to use the new colors, or do I need to implement a custom painter for each property?

I already call SwingUtilities.updateComponentTreeUI(window) after setting the properties in the UIDefaults .

EDIT:

The following code sets the L&F of the whole application:

 try { for( LookAndFeelInfo info : UIManager.getInstalledLookAndFeels() ) { if( "Nimbus".equals( info.getName() ) ) { UIManager.setLookAndFeel(info.getClassName()); customizeNimbusLaF(); SwingUtilities.updateComponentTreeUI( appWindow ); break; } } } catch( Exception e ) { LogUtility.warning( "cannot set application look and feel" ); LogUtility.warning( e.getMessage() ); }

The code does, what it is supposed to do (setting the Nimbus Look & Feel). The problem is, that the Painters of the Menu and other components work with the old colors.
The following code sets the colors:

 private final void customizeNimbusLaF() { UIManager.put( "control" , UIConstants.GREY_LIGHT ); UIManager.put( "nimbusAlertYellow" , UIConstants.YELLOW ); UIManager.put( "nimbusBase" , UIConstants.GREY_DARK ); UIManager.put( "nimbusDisabledText" , UIConstants.GREY_DARK ); UIManager.put( "nimbusFocus" , UIConstants.BLUE_LIGHT ); UIManager.put( "nimbusGreen" , UIConstants.GREEN ); UIManager.put( "nimbusInfoBlue" , UIConstants.BLUE_MIDDLE ); UIManager.put( "nimbusRed", UIConstants.RED ); UIManager.put( "nimbusSelectionBackground", UIConstants.BLUE_MIDDLE ); UIManager.put( "background" ,UIConstants.GREY_LIGHT ); UIManager.put( "controlDkShadow" , UIConstants.GREY_DARK ); UIManager.put( "controlShadow", UIConstants.GREY_MIDDLE ); UIManager.put( "desktop", UIConstants.BLUE_MIDDLE ); UIManager.put( "menu", UIConstants.GREY_LIGHT ); UIManager.put( "nimbusBorder", UIConstants.GREY_MIDDLE ); UIManager.put( "nimbusSelection", UIConstants.BLUE_MIDDLE ); UIManager.put( "textBackground", UIConstants.BLUE_LIGHT ); UIManager.put( "textHighlight", UIConstants.BLUE_LIGHT ); UIManager.put( "textInactiveText", UIConstants.GREY_MIDDLE ); // panel UIManager.put( "Panel.background", UIConstants.GREY_LIGHT ); UIManager.put( "Panel.disabled", UIConstants.GREY_LIGHT ); UIManager.put( "Panel.font", UIConstants.DEFAULT_FONT ); UIManager.put( "Panel.opaque", true ); // button UIManager.put( "Button.background", UIConstants.GREY_LIGHT ); UIManager.put( "Button.disabled", UIConstants.GREY_LIGHT ); UIManager.put( "Button.disabledText", UIConstants.BLUE_MIDDLE ); UIManager.put( "Button.font", UIConstants.DEFAULT_FONT ); // menu UIManager.put( "Menu.background", UIConstants.GREY_LIGHT ); UIManager.put( "Menu.disabled", UIConstants.GREY_LIGHT ); UIManager.put( "Menu.disabledText", UIConstants.GREY_DARK ); UIManager.put( "Menu.font", UIConstants.MENU_FONT ); UIManager.put( "Menu.foreground", UIConstants.BLACK ); UIManager.put( "Menu[Disabled].textForeground", UIConstants.GREY_MIDDLE ); UIManager.put( "Menu[Enabled].textForeground", UIConstants.BLACK ); UIManager.put( "MenuBar.background", UIConstants.GREY_LIGHT ); UIManager.put( "MenuBar.disabled", UIConstants.GREY_LIGHT ); UIManager.put( "MenuBar.font", UIConstants.MENU_FONT ); UIManager.put( "MenuBar:Menu[Disabled].textForeground", UIConstants.GREY_MIDDLE ); UIManager.put( "MenuBar:Menu[Enabled].textForeground", UIConstants.BLACK ); UIManager.put( "MenuItem.background", UIConstants.GREY_LIGHT ); UIManager.put( "MenuItem.disabled", UIConstants.GREY_LIGHT ); UIManager.put( "MenuItem.disabledText", UIConstants.GREY_MIDDLE ); UIManager.put( "MenuItem.font", UIConstants.MENU_FONT ); UIManager.put( "MenuItem.foreground", UIConstants.BLACK ); UIManager.put( "MenuItem[Disabled].textForeground", UIConstants.GREY_MIDDLE ); UIManager.put( "MenuItem[Enabled].textForeground", UIConstants.BLACK ); // tree UIManager.put( "Tree.background", UIConstants.BLACK ); }

The datatypes of the constants in UIConstants are either of type Color of Font depending of the attribute to be set.

Can someone tell me where my problem is?

Answer 1

no idea what did you tried, because

• set all setting for UImanager before creating an Swing GUI and starting AWT Thread

• you have to call SwingUtilities.updateComponentTreeUI(window) in all cases that Swing GUI is visible and you needed to change L&F on runtime

• separated issue could be with XxxUIResources , but no idea without seeing your SSCCE

• for better help sooner post an SSCCE demonstrated your issue about Nimbus L&F , value for UIManager and Colors stays unchanged

Answer 2

Change place on these to lines of code

       UIManager.setLookAndFeel(info.getClassName());
       customizeNimbusLaF();

to

       customizeNimbusLaF();
       UIManager.setLookAndFeel(info.getClassName());

I would like to add an alternative to this method proposed here.

In particular, all the problems related to the UIManager described in the following issue are solved by the material-ui-swing library with the concept of Material Theming System.

Material Theme System gives the possibility to set up your colors and style decision like with/without border, the border with round corner or not in a single class that is documented here under the package mdlaf.themes .

An example of usage can be the following one

  try {
      JDialog.setDefaultLookAndFeelDecorated(true);
      JFrame.setDefaultLookAndFeelDecorated(false);
      MaterialTheme theme = new MaterialLiteTheme();
      // here your custom config theme.setXXX();
      MaterialLookAndFeel material = new MaterialLookAndFeel(theme);
      UIManager.setLookAndFeel(material);
  } catch (UnsupportedLookAndFeelException e) {
      e.printStackTrace();
  }

You can keep around also the Theme, makes your custom change and when you are read call SwingUtilities.updateComponentTreeUI(window)
