jframe

问题 I'm trying to create a JFrame with a background image, a JLabel over the background image centered and toward the bottom, with two buttons on the right and left that say "Stay" and "Leave". This is already created. The issue arises with the order of each of the items. I cannot get the JLabel with text and buttons over the background image, with both of them showing. Here is my code; any advice would be appreciated. Thank you in advance. public class SceneOne { public static void main(String[]

问题 On my Mac, fullscreen JFrames initially have key bindings that do not work, and the computer outputs alert beeps each time I try to type. There is a workaround, though, after fully initializing my JFrame, I added these lines of code and all the errors stopped: setVisible(false); setVisible(true); Here's the source of this workaround: http://mail.openjdk.java.net/pipermail/macosx-port-dev/2012-November/005109.html Another problem which is yet to be solved is adding a mouse adapter to my full

问题 I've been trying for a while now to get a game working in Java, after much anguish over other peoples Sprite functions I made my own and don't understand why I can't erase it.

Does anyone have an idea why that is or how I can fix it? Link to google doc with images: https://docs.google.com/document/d/1eU6faW1d7valq1yE

This is necessary because I already have another Jtextfield below and a button 回答1: Don’t set a preferred size on the JTextArea . Set the preferred

问题 I need to have a JFrame, which when i change the window taskbar size or position, the frame shouldn't adjust itself. Which method of the JFrame will be called exactly on changing the taskbar size and position? Which method will I be required to override? To put it in more clear words, By default the instance of JFrame will adjust its height and width by itself when I change the size and position of the window taskbar. But my JFrame shouldn't respond when I extend the window taskbar or when I

问题 I'm going to start off by saying that I can almost guarantee that this question is going to be a copy but I couldn't find any other answers that suited my needs / worked on my program.

问题 I have created a simple compass program that moves the GUI box around the screen and I am now progressing on to adding NE, NW etc. This involves using JPanels as this allows multiple objects. My issue is that I've made 9 separate panels for the separate buttons but I have no idea how to add them to the JFrame as everything I do doesn't seem to work. Any ideas would be appreciated. import java.awt.*; import java.awt.event.*; import javax.swing.*; public class MovingCompassExtraJFrame extends
