问题 I want my frame components to be always adjusted in the screen, regardless of screen size. I draw the frame in my Laptop (small screen) and when I run my application in another machine (jar file) with a big screen the frame components doesn't re-size! How I can make my frame resize it's components when I put the frame in full-screen mode in any machine? Current layout Code package package_MSM; import java.awt.Color; public class MSMGui extends JFrame { private static final long

问题 I am creating a simple lottery as a practice, I am a beginner of Java. I have achieved almost everything that I want apart from one thing: Moving the different texts and buttons to the position that I'd like them to be. Here is a picture edited in Photoshop describing how I would like it to be: The Lottery currently looks like this after you press the Play button: (As you can see the buttons get shifted to the right in order to make space for the text that is squished in to the left of the

问题 If the array you are using is, let's say a length of 15, and you want to display them all at once, it shows them side by side in a really long display box: String[] options = {"Option 1","Option 2","Option 3","Option 4", "Option 5","Option 6","Option 7","Option 8","Option 9", "Option 10","Option 11","Option 12","Option 13","Option 14", "Option 15"}; int displayoptions = JOptionPane.showOptionDialog (null, "select one", "Title", JOptionPane.DEFAULT_OPTION, JOptionPane.WARNING_MESSAGE, null,

问题 I'm working with JFrames in Java, specifically with absolutely positioned elements that need to overlap. I understand that to overlay components, one should make a JPanel (with setOpacity(false); ), and position it with either setBounds(x,y,x2,y2); or setPosition(x,y) & setSize(x,y) . Unfortunately the panels act like CSS's inline-divs ; they take up only the needed amount of room on their line, and do not stack. This is the code I have so far, but it doesn't seem to act like I'd imagine it

问题 I have Labels and JButtons i want to define the position in JFrame. import java.awt.*; import java.net.InetAddress; import java.net.UnknownHostException; import javax.swing.*; public class GuiFrame extends JFrame { public static void main(String[] args) throws UnknownHostException { JFrame f = new JFrame("This is a test"); f.setSize(400, 150); JRadioButton ButtonServer = new JRadioButton("Server"); JRadioButton ButtonClient = new JRadioButton("Client"); InetAddress thisIp = InetAddress

问题 I am learning Java Swing and I appended a menuBar to the frame. By default this should call jframe.getContentPane().add(child) . When I ran the script the menuBar didn't show up. But the button was at the very top "y=0" if that makes sense. Then I realized my mistake I actually had to put in a menu in the menubar. Then the menuBar showed up. So that got me thinking...is the "menubar" "contentpane" actually 2 panels? It is confusing the hell out of me. Because that acted a lot like a panel.

问题 I have a bar at the top of my application that has a number of buttons either side of a JLabel. The button's visibility is dependent upon the current task a user is carrying out and one of the button's text may also change depending on the current state. What I would like to do is have a number of buttons stick to the left of the JPanel, the JLabel's center to be in the very center of the JPanel and the rest of the buttons to be to the right of the JPanel. So far I have managed to get the

问题 I have added the org-jdesktop-layout.jar to my libraries in my netbeans in my project. I found this .jar file in: C:\Program Files\NetBeans 7.0.1\platform\modules However the following line of code is still not recognized: org.jdesktop.layout.GroupLayout layout = new org.jdesktop.layout.GroupLayout(getContentPane()); I think I am missing the right import statement. What is the right import statement? If there is any other information that would be useful, let me know! Also what determines the
