问题 I'm sorry if the title is worded a bit incorrectly. I have recently started a new Game project, and have thought about the use of multiple JFrame s in Java. The reason being is my game has 2 JFrame s: 1) Main Menu ( which is a singleton) 2) Battle. Now the MainMenu JFrame will initialize the Battle JFrame on its own EDT, and then hide itself via setVisible(false) ,when the game is over setVisible(true) can be called from Battle frame on the MainMenu frame singleton. NB: The reason I did this

问题 Initially I was using JMenu and establishing hot keys to work using accelerator. It was working perfectly. Now I want the same behavior in JButton but I am stuck. Here is the code that I wrote : Please share your ideas so I can go in the right path. import javax.swing.*; import java.awt.Event; import java.awt.event.*; import java.util.Arrays; public class ShowDialogBox{ JFrame frame; public static void main(String[] args){ ShowDialogBox db = new ShowDialogBox(); } public ShowDialogBox(){

问题 I ran into an issue with specifying a html element's width in a JLabel and thought I would run it up the flag pole here and see if anyone had any advice. When I specify the width of an element using a "px" unit value, the resulting size is actually ~133%, whereas if I don't use a unit, or use "pt", I get the exact size I specified. In the below example, if you change the "width: 100px" to "width: 100pt", you will get the right size. This answer https://stackoverflow.com/a/6257861/131795 seems

问题 I have many tables in my Java application. When i click "Ctrl + A" in Mac OS X, it selects all rows inside the current table. I wonder if i can change the default shortcut to use "Command + A" instead to select all the rows in the table ? I am trying to do this inside the EventQueue class to be applied automatically on all the tables in my application. 回答1: Swing uses Key Bindings to map KeyStrokes to Actions . So you can add another binding to map "Command A" to the existing "Control A"
