Swing/AWT/SWT :: How To Enlarge The Clickable Area Of A JButton

Jan 30, 2015

what I have already tried:

to set the margin of a button - didn´t work
to set anything like padding - didn´t found something for java
to set an empty border - didn´t work

I don´t know what to try next.

My main problem is to enlarge the clickable area without resizing the buttons image.

Can Enlarge Image As It Is Print Out By Graphics By Scale Of 2?

Apr 8, 2014

So I have scale, and you can change it, like I print out a bufferedimage read by imageio from a file, can I enlarge it by 2x, because my tiles are too small eventhough they're 16x16, should I decided to decrease my tile grid from 40 to 20, but instead change the scale by 2. Can I enlarge the image as it is put on the screen?

import java.awt.*;
import java.awt.event.*;

public class MoveIt extends Applet implements ActionListener {

Swing/AWT/SWT :: Can Text Area Also Be Used For Input

Apr 7, 2014

I have a popup that displays textual info and sometimes gets text input from the user. I'm using the following code:

JTextArea textArea = new JTextArea( getGameHistory( true, -2 ) );
JScrollPane scrollPane = new JScrollPane(textArea);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
textArea.setFont(new Font("courier", Font.PLAIN, 12));
scrollPane.setPreferredSize( new Dimension( 30, 100 ) );
String input = JOptionPane.showInputDialog(null, scrollPane, "Fun Chess ",
JOptionPane.YES_NO_OPTION);

This shows a nice text area and an input field underneath it.The getGameHistory() method just returns a long string detailing the current game.Is there a way of just showing the text area without the input field underneath?Can the text area also be used for input instead?

JavaFX 2.0 :: ImageView With Transparent Image Not Clickable

Dec 29, 2014

I created an ImageView with an image with transparent portions. I also did some scaling and moving, which I though might cause this effect, but that is not the case. When I click on the transparent portion of the image the onMouseClick event is not fired. Other mouse events (mouse enter, mouse move, mouse exit, ...) get fired. Only when I click on the non transparent part the click event is fired.

Image img = new Image(getClass().getResourceAsStream("barrel_icon.png"));
ImageView view = new ImageView(img);
view.setScaleX(0.5);
view.setScaleY(0.5);
view.setOnMouseClicked(new EventHandler<MouseEvent>() {

[Code] ....

The area between the barrel and the shadow belongs clearly to the image, however is transparent. I am wondering if there is a reason for this behaviour and what is the best way to work around this issue, as my image has large transparent portions and the non transparent parts are hard to click on. By the way this is all based on JavaFX 2.2.

Swing/AWT/SWT :: JButton Does Not Do All Tasks

Aug 3, 2014

I have a jButton that when the action perform runs it only does part of the tasks some of the code doe not appear to run and i just can not figure out why i have tried wrapping parts of it in an if statement and it still do not run so here is the code behind the button:

in the code the parts that do not run are jTextField10.setText("Working Please Wait"); and jButton15.setVisible(false);

what i am expecting to happen is the text field has the words Working Please Wait placed in it , this does not happen and the button should be hidden to prevent it being clicked a second time again this does not happen

the rest of the code works as expected

InputStream inStream;
OutputStream outStream;
try {
File afile = new File("C://templates//amendments.xls");
File bfile = new File("C://amendments.xls");
inStream = new FileInputStream(afile);
outStream = new FileOutputStream(bfile);

[code]....

Swing/AWT/SWT :: Road Map Of Some Area Inside Desktop Application?

Jul 20, 2014

I try to create Java Swing Desktop application which show Road map of some area in JFrame. But pc not connected to internet it will be in LAN. Map should be like if we scroll the mouse we go down from height in map. Like zooming the area.

I try to find out by google i get lots of forum links but each showing me.

1. I have to do web application.
2. Google not support 'without internet' map facility.
3. I should use lots of jpgs which store in folder for showing map from various height so it look like when we see any map in Google Earth application.

I found goworldwind.org but not clear understanding right now.

Swing/AWT/SWT :: JButton Actionlistener Not Working?

Mar 5, 2014

I was suspecting I had a jButton not working, so I added a console print to test. See below. When I click the button, the console doesn't display anything. Am I using the button wrong?

private void jButtonUpdateItemsMouseClicked(java.awt.event.MouseEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

I have also tried the following with the same results (or lack of).

private void jButtonUpdateMajorDeckItemsActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

Swing/AWT/SWT :: Setting Icon On JButton

Feb 23, 2014

Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:

try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}

Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.

How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.

Here is the whole code...

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.io.File.*;

[Code] ....

Swing/AWT/SWT :: How To Change Action After 1st JButton Click

Aug 3, 2014

I am relatively new to java. . I cannot...(actually do not know) how to change the actionlistener (actionPerformed) after the second click in an array of JButtons. This is how the program performs right now.

On the 1st click on the grid, the border of the button clicked will change to 'blue' and another button will change its boarder to 'red'. on the next click the same action is performed.

What I need is to change action when the 'red' bordered button is clicked, lets say change the color of the buttons from the 'red' to the 'blue' buttons.(x 3 buttons).

The logic about how to perform the final result I think I can do on my own but my problem is how to change the action when the red bordered button is clicked.

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.BorderFactory;

Swing/AWT/SWT :: Search For A Key In Properties File - Jbutton Won't Work

Aug 26, 2014

I have a properties file with key values in it, now when I use my search box to search for a key in the properties file to check whether or not it is there - I can't get it to check and return the key value if it is theere. I've tried a few methods but keep getting a null pointer exception when it hits line 15 in the code all the time so I'm stumped at the minute.

My text field is called textFieldSearch

This is my button code

JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//search button
//find selected comman
String key_name = textFieldSearch.getText();

[Code] ....

This is my method code

public void FindSelectedKey()
{
if(textFieldSearch != null)
{
properties.getProperty(key_name == textFieldSearch)
}
}

Swing/AWT/SWT :: Making JButton That Switches Text From 2 JTextFields On Click With Mouse

Aug 6, 2014

I have made a window using JFrame and on my JPanel I have added 3 components: 2 JTextFields ("field1" and "field2") and inbetween them a JButton ("switch"). My goal is to switch the value of field1 to field2 and vice versa when the JButton is clicked. I thought this ActionListener which I have added to my JButton would achieve my goal:

public void actionPerformed(ActionEvent e) {
field2.setText(field1.getText());
field1.setText(field2.getText());
}

However, it changes the value of field2 into the value of field1 but not the other way around.

Swing/AWT/SWT :: How To Bold The Text In A Text Area

Something like "Alan: Hello, how are you?". I can't find a way to do this with a text area or on a string. Do any swing components suitable for use as text areas support bolding of certain sections of the string that you will set to it?
