In my main class I am just creating the frame and the panel then adding the panel to the frame.
I have swing UI designed and I want the components to resize when the frame is manually resized. The design is as shown in the fig Project UI.jpg
The panel 4 and panel 5 will change their contents according to the list item clicked. Panel 4 just has text area but panel 5 a panel with numerous components as label, combo box, text field,check box will be present.Now if the frame resizes, I won't all the components to resize according to the frame size.
My JPanel when adding components to it will never make its self larger but it will make my components inside smaller even though I have set the minimum and preferred sizes for those components? I am using the GridBagLayout for my layout manager as I am trying to get used to it.
I am trying to to insert time onto my jFrame (Netbeans) by using textfields. this is the code i've tried to put into the textfield so whenever i run the program it automatically shows the time.
As said, running the jar file instead of exe file the splash screen is displayed.
I printed some logs into splash screen class: when I run the app from the jar this logs are printed, instead when I run the app from .exe file these logs are not present.
there is a main JPanel in my application in that main JPanel i want to add two JPanels with a seperator in between . Though i have added the seperator but its taking some extra space and when i am changing its size , there is no effect . how can i remove/reduce this extra space taken by JSeperator? below is view logic ,
mainPanel = new JPanel(new GridLayout()); jp = new JPanel(new GridLayout(8, 2, 5, 5)); jp2 = new JPanel(new GridLayout(8, 1, 5, 5)); jText = new JTextField(10); jText2 = new JTextField(10); jText3 = new JTextField(10);
I'am new to java, this question may have been asked earlier but I'm not getting the exact answer.I want to add data from database into at and display it through jsp. But empty or null values is shown i.e no data is being displayed and when I execute the same sql query which is used in code in sql server then required output is displayed. My java code is:
Java Code:
public List < Alarm_Bean > get_Count(String system_Name) { if (system_Name.equals("MPS")) { try { con = getConnection(); stmt = con.createStatement();
So for a test i have a small array set as a jlist which is the contents of my jscrollpane, and it appears as if nothing is there until i adjust the window size by dragging it out or in... whats going on?
I made a web app to test the ServletContextListener in tomcat according to the book head first servlets and jsps and used the code
out.println("test context attributes set by listener<br>"); Dog dog = (Dog) getServletContext().getAttribute("dog"); out.println("Dog's breed is: "+dog.getBreed());
in the listener class.But the output is showing the first line only and the second println() is not showing any output whereas my Dog class compiled successfully and I didn't see any NullPointerException as expected in the book but somehow it seems like the problem is in the 2nd line of code only but I don't know what.
I also tried to add a 4th line at the end with println() only but with a simple text even that is not running but when I put that same line after the 1st line, the output is shown.I am unable to see what has gone wrong in the 2nd line of code.
I want to import an image to resize but not sure how to start of.Should I be using the "BufferedImage & ImageIO.read" method or the "paint(Graphics g) { Image img1 = Toolkit.getDefaultToolkit().getImage" method?
I need to make a code that will ask the user for an array size and the numbers that go in the array. Then it must ask for a new size and copy the numbers from the first array and add numbers to fill the new array.
import java.util.Scanner; import java.util.Arrays; public class Lab07{ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("How many numbers do you want to enter?");
[Code] ....
I can make the first array but I am getting stuck on the second this is what I am getting back
How many numbers do you want to enter? 3
Enter the 3.0 numbers now. 7 1.2 9
These are the numbers you have entered. [7.0, 1.2, 9.0]
How many numbers do you want to enter? 5
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3 at Lab07.resizeArray(Lab07.java:27) at Lab07.main(Lab07.java:18)
I have a problem with my program. My aim is to display in a JPanel, 2 rectangles, and resize them by clicking. I want to give the user the ability to change the height of the rectangles (independently) by moving the top and/or bottom edges. Currently, it displays the 2 rectangles, but impossible to resize and I can not find the solution.
Java Code:
import java.awt.*; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.util.ArrayList; import javax.swing.*; public class Resizing extends JPanel { private static final int PREF_W = 600;
Whenever I make something in Swing, I always need to resize the window for me to see the graphics on the window. I have been told to use the pack() method on it, which I have, but the problem with it is that it just sets the window to a minimal size, only displaying the x + and -.For one of the "games" I made, it at first didn't work until resize, then I added a repaint() after the constructor and it worked for me, but when my friends download it they cannot see it.
I need to create a program that draws a graph, but for now, all I have done is two lines: the X and Y axis. The program is designed in a way as to automatically resize the graph when the window is resized.
Is this code in some way extremely inefficient? I get TERRIBLE flickering when I resize the window. Is there something that will at least reduce the flickering?
mainApp.java: import java.awt.*; import javax.swing.*; public class mainApp { public static void main(String[] args) { JFrame frame = new JFrame(); frame.setSize(300,300); frame.setVisible(true);
[Code] ....
I have added a screenshot that shows the window flickering.
Suppose i have a book class and bookArray class.in book class contains four fields name,id ,publisher and author. in bookArray class: book bookArray=new book[20]; i have to save those four fields in the array but after completed the array i should have re-size the array with contains the previous data. How?? I have pass those values from the main class..
I have a problem with my program. My aim is to display in a JPanel, 2 rectangles from an arraylist, and resize them by clicking. I want to give the user the ability to change the height of the rectangles (independently) by moving the top and/or bottom edges. There is errors in my code but where ? Netbeans underlines 2 lines (in bold).
Any way to resize an ImageIcon when placing it on a Button so that I don't have to physically rezize the image file?? I am writing an Application, not an applet, so the getImage method won't work.
I have created a small program with methods of the Graphics class. I want to resize the frame and make it fit the screen, but after trying various layout managers, have come to the conclusion that by setting the sizes of the various shapes specifically in the paintComponent method, I can't resize. Is it possible to resize a frame with its paintComponent methods? Maybe I'm just not using the layout managers correctly but the Graphics just wont resize. I have tried setting the weights when I used GridBagLayout.. not working. I thought maybe there is a way to set the frame or panel to take the Graphics and then resize the panel. That doesn't work either.
Lets say the JDialog opens 5x5. The user is allowed to modify its size to be any size larger than 5x5 but is not allowed to make it smaller. Is there such a property or will this have to be regulated via code?
Is it possible to allow users to resize columns in a JTable that has no header? I'd like the user to be able to grab the column lines on any of the data rows and be able to resize just like they can in the header.
I am looking for a way to find a resize animation for an application I'm developing. I found this answer but I figure there could be a better method out there,

I am just looking to select something in a list, then press a button which would enable the animation and enlarge the stage. This will happen twice.
