Swing/AWT/SWT :: When Maximize JInternalFrame Controls Disappear

Jun 17, 2014

I got a JFrame with its JDesktopPane, and opens a JInternalFrame at the beginning of the execution of the application. That's all fine.

And then, the first JInternalFrame opens another JInternalFrame in its maximum size, and that's when a simple JLabel that I got o the second internal it disapears. Why?

JavaFX 2.0 :: Slow GUI Response When First Displaying Controls

Jun 15, 2015

I have been using JavaFX for some time now and have encountered many performance issues, mainly with the initial display of GUI elements.  For example, a simple stage with a table view (with about 10 columns) and chart takes about 5 seconds to display.  A color picker will take about 3 seconds from the time I click the control to when it displays the pallet.  This only happens when the controls are first displayed.  This can't be right.  I have searched and none seems to have a similar problem so I thought I would ask here just to make sure.  Here is a sample Hello world that shows the problem with the color picker (takes ~ 3 seconds to show pallet when clicked). 
 
public class HelloWorld extends Application
{
    @Override
    public void start(Stage primaryStage) {
        StackPane root = new StackPane();
        ColorPicker cp = new ColorPicker();
        root.getChildren().add(cp);

Swing/AWT/SWT :: Controls Not Updating Until Method Is Completely Finished

Dec 30, 2014

I have this method that does several RegEx queries along with a lot of searching and replacing of text, and each regex search / replace takes some time and a total of maybe two minutes for all of them to finish up. So I added a ProgressBar to my JavaFX form and I added code after each step to simply use the ProgressBar.setProgress method by a factor of 10% each step ... so the code would resemble something like this:

do a regex query
if it finds things then do a replaceAll method on the string being searched
ProgressBar.setProgress(.1)

do another RegexQuery
If it finds stuff, so a replaceAll method
ProgressBar.setProgress(.2)

etc...

What is happening is that the progress bar will not actually paint any progress until AFTER the entire method is done executing. So from the users perspective, they click on the button and the program appears to freeze until its all done with that method at which point it instantly changes the progress bar to the last value I set ...

So the desired effect is simply not working, and I don't know why.

I tried changing (as in replacing the progress bar with a different control) the progress bar value settings with updating text in a text box on the form, and even that didn't display any of the text messages until AFTER the procedure was done executing at which point, all of the text logs appeared at one time instead of gradually adding text to the box in increments as the method executed.So it FEELS like any time a method is actually running, the JavaFX scene simply freezes until the method is done running. And it doesn't matter if I change the progress bars value directly or put it into its own method which gets called throughout the execution of the regex method ... either way, nothing actually happens on the form until the software is done executing all of the procedures called and then it comes back to a "resting" state...

I tried simplifying it by making a single method that does two things ... it updates the progress bar and then it waits for 1 second. Then it increments a variable then updates the progress bar, then waits a second, thinking to myself that 1 second pause would give it time to update the progress bars value but even that little method would not work.

Here is the test method I created:

private void testProgressBar() {
for(int x = 0;x<10;x++) {
progressBar.setProgressBar(.1*(x+1));
try {
sleep(1000);
}
catch(InterruptedException e) {
e.printStackTrace();
}
}
}

Even that little piece of code will not actually show any changes in the progress bar until after its done looping at which point, the progress bar is filled to 100%, but I never see the first 9 changes in the progress bar within that for next loop.

JavaFX 2.0 :: Styling Of Controls Doesn't Work programmatically

Dec 9, 2014

I have a stylesheet (mystylesheet.css) with following entry:
 
.flowpane{
    -fx-background-color: rgb(0,0,0);
}
 
In then start-method of my application I execute:
 
       StackPane root = new FlowPane();
        Scene scene = new Scene(root,primaryScreenBounds.getWidth(),primaryScreenBounds.getHeight());
        scene.getStylesheets().add(css.getFile());
        root.applyCss();

No FlowPane gets black. But if I do that in SceneBuilder and add the stylesheet to root than after loading Fxml-file the FlowPane gets black.

Another approach:

        StackPane root = new FlowPane();
        Scene scene = new Scene(root,primaryScreenBounds.getWidth(),primaryScreenBounds.getHeight());
        scene.getStylesheets().add(css.getFile());
        root.getStyleSheets().add(css.getFile());
        root.applyCss();

Nothing happens.

        StackPane root = new FlowPane();
        Scene scene = new Scene(root,primaryScreenBounds.getWidth(),primaryScreenBounds.getHeight());
        scene.getStylesheets().add(css.getFile());
        root.getStyleSheets().add(css.getFile());
        root.getStyleClass().add("flowpanel"); 
        root.applyCss();

Doesn't work too;
 
but root.setStyle("-fx-background-color: rgb(0,0,0) works. But I need to style my application by css-files.

Use 2D Array To Layout Map With Pictures

Jun 2, 2014

I'm making a Pacman look-a-like game, now I'm making the map out of an 2D array (as a grid). I already initialized the 2d array spots with "0" and "1". I managed to do this but now I'm stuck.

I want to use the "0" and "1" to print the map. For example the "0" are grass and the "1" are walls. The map should be printed within a JFrame. And I would like to make the width and height 32x32 pixels.

I searched on the internet and i found a couple of example codes but non of it seems to work properly. This is the code I'm using to make the 2D array and initialize the spots.:

public class Level1 extends javax.swing.JFrame{
final int ROWS = 17;
final int COLS = 17;
int[][] field = new int[ROWS][COLS];
public Level1() {
initComponents();
setLocationRelativeTo(null);

MVC Layout - Adding Listeners?

May 4, 2014

So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?

Method 1:

View Class ActionListener method:
Java Code: public void addMovementListeners(ActionListener u, ActionListener d, ActionListener l, ActionListener r){
moveUp.addActionListener(u);
moveDown.addActionListener(d);
moveLeft.addActionListener(l);
moveRight.addActionListener(r);

[Code] ....

Which method is better? Is there another method that is even better than these two? Trying to get this MVC thing down.

Grid Layout Implementation

Mar 13, 2014

How to implement GridLayout. In my applet, I want to make a grid of 2 rows and 2 columns. In each grid I want to add a Label and a TextField. I want the background to be red.

So my code would be?

import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class GridLayoutApplet extends Applet implements ActionListener{
// construct components
Label fNameLabel = new Label("First Name");
TextField fNameField = new TextField(20);

I have read about panels and frames but, it is all confusing to me. How can you add a label and a TextField to one square of the grid?

Arranging Layout With JFrame

Aug 7, 2014

I'm just trying to do a simple JFrame class, with standard menubars, labels, buttons, etc. So far, it looks really bad. The only way I can get it to look somewhat decent is if I pack it, but then the GUI is too thin. When I resize it manually, I can get the correct position by sizing it to something specific, but it obviously changes when resized again, and I don't want to set dimensions, if my users are just going to resize it, and mess it up. I want the labels on the left, textboxes neatly to the right of them, and the button somewhere on the bottom.

I also want to dynamically create a new label, textbox and button when they click on "Write File" from the menu bar - I assume this is just done with action listener, but I have enough problems as it is with formatting my layout, that I don't even want to start on it!

import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;

JFrame Layout Appearance

Dec 4, 2014

Below is my assignment and as you can see there is lots of empty space and it looks a bit ugly. Im currently using

content.setLayout(new GridLayout(5,1));

as follows:

Welcome Label and four buttons in the top JPanel,
"Employee count" and JTextField in the second JPanel,
"Employees in System: ", and empty JList in the third JPanel,
Delete employee and Edit Employee buttons in the fourth JPanel
Exit button in last JPanel.

When I set the size any smaller, the buttons sort of shrink into each other so Im looking for a way to have the panels take up less space? At the moment it seems like each of the panels are set to the same size for some reason, regardless of the content.how can I give the frame less vertical height without ruining the content.

JSP :: How To Have Common Page For Different Action Name But Have Same Layout

Mar 16, 2015

I have developed a web portal using jsp and struts 2. I have approximately 10 JSP pages which looks exactly the same and have two text areas and two hidden fields. All 10 pages are exactly the same except for hidden field value. Can't i have a single common jsp page. How can i achieve it. A sample page i am attaching...

<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ page pageEncoding="UTF-8"%>
<%@ page language="java"%>

As this is an Assignment page so hidden field value is assignment. If the page is OBJECTIVEs then value will be OBJECTIVE.

How To Create A Custom Layout Pattern

Feb 19, 2015

I would like to implement a custom Logging strategy for my Java project.I have implemented 3 appenders : one console-log, one file-log (errors only) and another (custom) file-log (with the custom parameters).The custom parameters are : loggerName, logPathDir, logFileLevel and layoutPattern.

I have not managed yet to implement a custom layoutPattern strategy for the custom file-log.When I launch my tests : test1 (default logging setting) and test2 (custom logging setting), I have only managed to get a sucessfull status if I switch the custom layoutPattern strategy to the default one for the test2. My implementation extract :

// Layout patterns : default (layout) and custom (patternLayoutCustomBuilt)
Layout<String> layout = PatternLayout.createLayout(PatternLayout.SIMPLE_CO NVERSION_PATTERN, config, null, null, false,
false, null, null)
PatternLayout.Builder patternLayoutCustom = PatternLayout.newBuilder();
PatternLayout patternLayoutCustomBuilt = patternLayoutCustom.withPattern(layoutPattern).wit hConfiguration(config).build();

Swing/AWT/SWT :: Alternative To Null Layout

Aug 10, 2014

My IDE has a visual editor for creating Swing applications. The created application windows have no layout manager and use method "setBounds()" for placing Swing components on the application window. I have built an application that uses JInternalFrame. Each JInternalFrame is a separate and different "screen" for the user to interact with.

There are around 2,000 screens in the application and new screens are constantly being added as well as existing screens being modified. As a result, the top-level container - a JFrame - is a fixed size and is not resizable. I have now been asked to increase the size of the JFrame while maintaining the proportions of the screens.

Rather than manually editing the invocations of "setBounds()" on all the screens, any alternative way to achieve this? Also, is there a way to achieve this such that if, in future, the JFrame will again be resized, the screesn will automatically adjust?
