Scrollpane Scrollbars To Entire Jframe When Resizing / Adding Components
Jul 23, 2013
I am trying to add scrollbars to my frame containing many different components and appearing when user resizes the window with the mouse adds pictures and admin of this online application adds labels or other components.
I want scrollbars to appear when the frame is resized and has components you don't see under so you can scroll down.
If I have for example this code, how i add the scrollbars when i make frame smaller ?
public class Test extends JFrame {
private JPanel contentPane;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
[Code] ....

I am trying to develop a GUI through hard coding. I encountered a challenge:
I created a Jframe and onto this I added a JPanel. I assigned thge flow layout manager of the frame to null(because i want to do the positioning of my components manually)
The program is running perfect except when i click the maximise button of the frame, the JPanel does not change its size.
With Netbeans IDE - i found that the propert is Horizontal Resizable propert. I have tried to look for the method but in vain.
I am trying to develop identical things from hard coding and in drag and drop environment. so with drag and drop its easy but in hard coding how do I work it out?
Here is the code :
public class JPanelDemo {
JFrame frame;
JPanel panel;
JPanelDemo(){
createFrame();
[Code] ....

I have the following project:
Java Code:
package boxmatrics;
import java.awt.BorderLayout;

import javax.swing.JFrame;
public class BoxMatrics {
public static void main(String[] args) {

Why I have to resize the window(JFrame window) manually, with the mouse, in order to see the components?Where do I need to call repaint(); ?

I made UpdateInmateDisplayer a Singleton so that I could access it from the private class ButtonHandler. It works to display the first inmate's number on the screen but when I close out the window and click the Book Inmate button in CurInmatesDisplayer again, it only shows a blank window. I've tried adding the components again from the ButtonHandler in CurInmatesDisplayer but it doesn't work.

In a project I'm ivolved in I have to dynamically add some components. All was going well until I had to generate data tables dynamically. I'm iterating a list of "SomeObject" and when I try to access a property of that object Glassfish tells me that object doesn't have such a property that is readable. I have getters for those properties and SomeObject implements Serializable as well. I used BalusC resources but I'm having no luck.

The program loads, but nothing shows. I did some research and saw that I needed to set the JFrame to visible at the bottom of the frame section. I made the change, but it still does not show anything. Do I need to add everything that I added to the content pane to the frame? From my understanding you add elements to the panel, the panel to the contentPane, then the pane to the frame...

I decided to write a small Java program to experiment around with BorderLayout, because I'm developing a Java game and I need to have 2 objects placed in a single JFrame at the same time, and everyone I asked said I need BorderLayout to do that.Before you answer: Also, is using BorderLayout the best option for adding multiple video game oriented objects such a sprites to a JFrame?
So the Java program I wrote is supposed to place a JButton on the JFrame and ALSO place a graphic component (a rectangle in this case). The problem is, only the button shows up, as can be seen in the image link below: URL....
Here is the code:
**main.java** --> The main method class + JFrame/JPanel/JButton constructor
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class main {

I am making a table that is dynamically made but it isn't working with scroll bars. The scroll bars show but don't work. Here is the code:
JPanel pList = new JPanel();
Component pListl = new JLabel("Here you can view and search for players.");
pList.add(pListl);
tabbedPane.addTab("Player List",pList);
tabbedPane.setMnemonicAt(0,KeyEvent.VK_1);
[Code] ....
Yes I am spamming entries into the result object, this is so I can test the scrolling as right now I don't have enough data for overflowing entries but will do soon.

I using this code to fir FlowPane into ScrollPane
FlowPane flowPane = new FlowPane(Orientation.HORIZONTAL);
ScrollPane scroll = new ScrollPane();
scroll.setContent(flowPane);
scroll.viewportBoundsProperty().addListener(new ChangeListener<Bounds>() {
@Override
public void changed(ObservableValue<? extends Bounds> ov, Bounds oldBounds, Bounds bounds) {
flowPane.setPrefWidth(bounds.getWidth());
flowPane.setPrefHeight(bounds.getHeight());
}
});
Unfortunately this maybe is not the best solution. Is there another more simple way to fit FlowPane into ScrollPane in Java 8?

I am trying to get a scrollPane working correctly, but not having any luck. The picture drawn in the center panel is quite large and goes off the screen. I visited URL... but I am missing something vital. Both tracks show, but there is no knob to do the scrolling.
public DViewer() {
super();
frame = new JFrame();
frame.setSize(Toolkit.getDefaultToolkit().getScreenSize());
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

I am having problems trying to get my jPanel to display my drawings properly after scrolling. (My drawings is done using by overriding the paint() method as the paintComponent() method does not work in my case.) My jPanel is component of my JScrollpane, and my JScrollpane is part of my jFrame.
The organization of components is: JFrame <-- JScrollPane <-- JPanel ( <-- means added to).
Situation: My drawings did appear when the frame becomes start, but when I start scrolling the scrollbar in any direction, it starts to eat up my drawing leaving only part of drawing which is not affected by scrolling.
I want my jpanel to display the drawing properly even after scrolling in both vertical and horizontal directions. I did use revalidate and repaint methods in my method for start of the JFrame.
Some Ways which I have tried:
1) I have tried adding this.revalidate() and this.repaint() method to the paint() method which did retains the image, but the jPanel keeps blinking on my screen which is trying attempt to update the drawing in a recursive manner.
2) I have tried panel.repaint() and panel.revalidate() in my paint() method, but it did not display my drawing.
3) I have read from other sources that I needed a listener to do it, but I am not sure how it works.
// Code Use for Listener
jScrollPane1.getViewport().addChangeListener(new ListenAdditionsScrolled());
public class ListenAdditionsScrolled implements ChangeListener {
public void stateChanged(ChangeEvent e) {
jPanel3.revalidate();
jPanel3.repaint();
}
}

I'm trying to implement a scene with a ScrollPane in which the user can drag a node around and scale it dynamically. I have the dragging and scaling with the mouse wheel working as well as a reset zoom.
Here's my issue:
I'm having trouble with the calculations to fit the node to the width of the parent.
If I zoom in or out, the fit to width does not work.
If I change the window size after running fitWidth() once, the fit to width does not work the second time.
Here is my code as an SSCCE and how it works...
1. (works) Mouse wheel will zoom in and out around the mouse pointer
2. (works) Left or right mouse press to drag the rectangle around
3. (works) Left double-click to reset the zoom
4. (doesn't work) Right double-click to fit the width
My calculations to re-position the rectangle to the upper left of the pane and fit it (i.e. scale it up or down) to the width of the parent are incorrect.

import javafx.animation.KeyValue;
import javafx.animation.Timeline;

I want to create a ScrollPane where I can scale the contents. Think of a simple drawing program that allows you to zoom in and zoom out.
If I create a ScrollPane in SceneBuilder and then drop a couple of Circles into the AnchorPane all looks good.
If I then set a scale of 0.5 for the AnchorPane Scale X and Scale Y the AnchorPane gets scaled about its centre leaving space between the left and top edge of the AnchorPane and the left and top edge of the enclosing ScrollPane.
The only way to get the AnchorPane so that it aligns with the top left of the ScrollPane seems to be to add a negative amount to Translate X and Translate Y.
In my application I would like the user to be able to adjust the zoom (Scale) continually and also the size of the AnchorPane must be allowed to change as the user add/deletes/edits content.
Does this mean I have to continually monitor the AnchorPane properties and set compensating Translate X and Translate Y values each time? Or is there an easier way to achieve what I want?
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.paint.*?>
<?import javafx.scene.effect.*?>
<?import javafx.scene.*?>
<?import javafx.scene.shape.*?>

I have to write a resize method so that when my Bucket gets to a certain point, then it resizes the bucket when it is called. What is happening is, I am getting strange results when I run the method. My mean bucket length should be at 2.5 for the last insertion, but I am getting something like 0.1346. Here is my dictionary class
// The "Dictionary" class.
// The Dictionary class implemented using hashing. Hash buckets are used. A dictionary contains a set of data elements with corresponding keys. Each element is inserted into the dictionary with a key. Later the key can be used to look up the element. Using the key, an element can be changed or it can be deleted from the dictionary. There is also an operation for checking to see if the dictionary is empty.
package dictionary;
public class Dictionary {
protected final static int MAX_BUCKETS = 1000; // number of buckets
protected DictHashEntry[] buckets; // the bucket array
private int collisionCount = 0;
