jbutton

问题 It is often necessary to change the behaviour of other GUI objects depending on the state of another GUI object. E.g. when a button is pressed, a label shall change its name. However, when I use an AbstractAction object like JButton myButton = new JButton(myButtonAction); I need a reference to the GUI objects in the object that inherits from AbstractAction. Should I just create the AbstractAction objects in the GUI and then pass all the necessary GUI references to the AbstractAction objects

问题 So recently, I have been trying to make my own Mario game (for myself, possibly to show my other friends). Games include buttons. When I click on a button in other games, it plays a sound. I would love to add that feature to my game. The problem is, it doesn't play. My source code is: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.File; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import javax.sound.sampled.Clip;

The images have been used in the background of the program and buttons. Please see the diagram below which shows the program I desire to convert to a jar. IMAGE As you see above the program runs OK. I created the same program with no custom background and custom buttons containing no images and I successfully packaged it into a jar and subsequently into an .exe file.

I want to add an extra cell with each row(dynamically) that contains two buttons...and on clicking those buttons some event should occur only on the respective row ..

问题 I recently read this thread (Creating a custom button in Java) on creating custom buttons in java by extending the JButton class, however all the solutions on this thread use graphics drawn in java. I wanted to have my button based on a button image I had drawn in photoshop. So I tried to apply what I read in that thread with this result: import javax.swing.*; import java.awt.*; public class nextButton extends JButton { @Override protected void paintComponent(Graphics g) { Image image = new

问题 For my project, I need to create customizable buttons. Except that I have a problem and I do not know how to solve it. I have a background image for my button and I would like it to be extensible in X and Y according to the text there will be over without loss of quality. Do you have any ideas? 回答1: Swing has a pluggable Look&Feel which allows to alter the appearance of its widgets by means of a ComponentUI (in this case: a ButtonUI ). Example for your buttons: class StyledButtonUI extends

问题 Here is the screenshot of what I want to do : What's happening there is the JButton shows correctly but nothing happens when I click on it.
