look-and-feel

问题 Hello I am trying to change the colors of my swing progress bar in java. Initially I tried using the following code: UIManager.put("ProgressBar.selectionBackground", Color.black); UIManager.put("ProgressBar.selectionForeground", Color.white); UIManager.put("ProgressBar.background", Color.white); UIManager.put("ProgressBar.foreground", Color.RED); m_progressBar.setBackground(Color.BLACK); m_progressBar.setForeground(Color.red); But none of the commands seemed to have any effect!!!

问题 I know this question has been asked a million times, and can be done by overriding paintComponent() , but what I want to know is how to change the shape while respecting the current Look And Feel. If I want to change the shape to a circle, I also want the button to look like a button, just with a different shape. I tried making a JButton, the overriding paintComponent , then clipping it to a circle, but I didn't get the border effects on Nimbus LAF . Is there a better way? Or is there a

问题 I have a simple-ish cell renderer which is composed of a few JLabel s (the renderer itself extends JPanel ) and I'm trying to get it to render sensibly in the Nimbus look and feel. Basically what is happening is that in the lighter rows (as Nimbus has alternate row coloring ), my specific cell renderer is using the table background color (which is much darker than both lighter and the darker row colors). In my renderer I do: if (isSelected) { setBackground(table.getSelectionBackground); }

问题 I have a VB6 application where I'd like to have a consistent behavior among its controls application-wide. One of the behaviors, for example, would be highlighting a text box when it gains focus and removing the highlight when it loses focus. I'd like this to happen on every form. What I'm trying to do is have one sub procedure that can be called by all forms when they load that will make this behavior happen. That way, I don't have to manually code for each individual text box to make it

问题 In my Java Swing app I have some JTextAreas, I realize the text looks different when it's run from Netbeans and when the app is run from a Jar file, why ? How to make them look the same ?

问题 i want to know how to set the color of a button (in example, but i will need to set every component color) with the apple look and feel. I found an answer in stackoverflow that suggest to change to the standard look and feel, that works for me, but i prefer not to change because I like apple's one. Is there any solution? I know there is because I saw many apps written in java that have colored buttons and also that use particular styles or images as background. Can you tell me a solution? 回答1

问题 Can anybody see what I have done to cause the NullPointerException (stack trace below)? The panel appears OK: Textual output os.name: Windows Vista os.version: 6.1 java.version: 1.6.0 java.vm.version: 1.6.0-b105 java.vendor: Sun Microsystems Inc.

问题 Note to reviewers: This may be a (possibly known) bug in NimbusLookAndFeel, and is not (as yet) a dup to the canonical NPE question. I have multiple classes, but I have no clue which of them the Exception might imply.
