JavaFX 2.0 :: Determine Which CombBox In A Pane Has Been Clicked?
May 14, 2015
I have a pane with numerous comboboxes. Each ComboBox must perform an action when the mouse button is clicked on the ComboBox (OnMouseClicked). I have written a function that operates on a particular ComboBox, but I want to generalize it to operate on any of the CombBox objects clicked. I think the function should resolve the CombBox object within the function itself, and perform the operations on that ComboBox. But, I don't know how to get the ComboBox from within the function itself.
I have tried viewing the ComboBox documentation, but there doesn't seem to be a method that lets a clicked ComboBox notify the OnMouseClicked action which ComboBox has been clicked. How I go about identifying the clicked ComboBox within the OnMouseClicked function?
I want to have a button that will include another node beyond the text and image that are part from the Button. This node as example will be a circle that I will change his color from gray to green if the button was pushed.
I try to do this with Background / BackgroundFill with no success
I tried to get access to the Pane / Region of the Button, but I can't find a way to do it.
We needed to use a GUI via JOptionPane with our program. So that we may turn out programs in as executable jar files. However, I have never used it. Here is my problem and code:
Now for some reason I am getting an error when trying to create a new instance of the Person class and pass inputFirst and inputLast. Its telling me that I have not initialized inputFirst or Last. When I allow it to initialize it sets inputFirst = null; and so forth with inputLast. All I want to do is pass the two Strings to my constructor in my Person class.
while using JOption Pane. So my output for the code is correct, however, it keeps repeating the dialog.
public static void main { String y = ""; String aString; int a, sum; double average; int count=0;
[code]....
My output for the first input ends up like this:
You have enter 1 as integer. Sum = 1 Average = 1.0
So far so good....however when I add another input.
You have enter 1 as integer. Sum = 1 Average = 1.0 You have enter 1 as integer. Sum = 2 Average = 1.0
What I want is the You have enter, sum,average to show up once while still adding sums and average.I tried moving string y out of the while loop and used if statement but to no avail.
I have my below Swing GUI code in which I want to read and display some contents present in text file say (test.txt) which is located in my local disk (C: est.txt). My pane tab 2 is divided into two halves horizontally. How can I read and write the test.txt file contents under the tab tab2 in the first half of the pane(where currently it is 2 written)?
Sample test.txt present in my local hard disk location username:test1 Password:test1 DataBasename: testDB
CODE FOR TABBED PANE
import javax.swing.*; import java.awt.*; public class SplitPaneExp { public static void main(String[] args){ Runnable r = new Runnable() { public void run() { JFrame frame = new JFrame("WELCOME");
I'm dealing with, change the content pane color of jFilechooser. Color has been changed but the problem is when I open the subdirectory leads errors; Note : It also trigger error when I set default directory; like chooser.setCurrentDirectory(file);
The following error is the result:
Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException at javax.swing.plaf.metal.MetalFileChooserUI$IndentIcon.getIconWidth(MetalFileChooserUI.java:912) at javax.swing.SwingUtilities.layoutCompoundLabelImpl(SwingUtilities.java:961) at javax.swing.SwingUtilities.layoutCompoundLabel(SwingUtilities.java:888) at javax.swing.plaf.basic.BasicLabelUI.layoutCL(BasicLabelUI.java:94) at javax.swing.plaf.basic.BasicLabelUI.getPreferredSize(BasicLabelUI.java:239)
Using JOptionPane,ask for 10 numbers from the user.Use an array to store the values of these 10 numbers.Output on the screen the number with the greatest value.
The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.
I have two classes one is called main.java another is called Gui.java
in gui.java, will create a JFrame and some component.here is some code in main.java.
Java Code:
public static void main(String[] args){ while(true)//will always loop once user close the window Gui gui = new Gui(); gui.setVisible(); if()//at here need to determine button in Gui.java is press or not to process the user input { String fromUser = gui.Jusertxt.getText(); }
} mh_sh_highlight_all('java');
what is the code need to use to know Button in Gui.java is clicked or not? i try use method to return true value, but in not working.
im trying to play a sound when button is clicked. here is the following code
InputStream in; try { in = new FileInputStream(new File("failure1.wav")); AudioStream audios = new AudioStream(in); AudioPlayer.player.start(audios); } catch (Exception e) { }
just wondering why it does load;
i do get the warning
warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioPlayer is internal proprietary API and may be removed in a future release AudioPlayer.player.start(audios);
I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package UI;
I want the Jbutton Button1 icon to change when i click it howerer i am getting the error can not find symbol for the code in the actionPerformrd method.
I'm new to java and I'm currently trying to make a program that uses a JTree that implements a properties file. I have the Keys set to the nodes but I want it so that when the node is clicked it will retrieve the keys value from the prop file.
I did have some code for this initially but I as it did not work at the time and was causing issues to my project I got rid of it. I have my code for the jtree,the listener and the prop file.
Tree
Java Code:
JPanel panel_1 = new JPanel(); panel_1.setBackground(Color.WHITE); panel_1.setSize(new Dimension(22, 0)); scrollPane.setViewportView(panel_1); Properties properties = new Properties();

Java Code: add = Adds files changes in your working directory to your index. Example: git add .
rm = Removes files from your index and your working directory so they will not be tracked.
I have a question and wasn't able to find what I needed through the search. I am currently using Netbeans 8.0 and working on a desktop app. I have a main GUI file where I am going to add a menu item that can be clicked to open up an "About" Dialog box. The problem is, I don't know how to do this
The file are...
MainGui.java About.java
How would I go about opening the About.java when clicking on a menu item? I tried using...
I'm working on an applet for my class. I decided to use AWT even though it's really old.
I'm having trouble with the labels on my program. They don't show up until I click another tab in the browser and then go back to it each time after I click on a button. I tried to use repaint() but it doesn't seem to work. What can I do?
What it's supposed to do: This code is supposed to see if the clicked card is selected. If it's not, select it and show the player where it can move / attack. If it is selected, then find out what card the player clicked on. If he clicked on the card that was already selected, deselect it. If he clicks on a friendly card (same playerID), then select that card. If he clicks on an enemy card (different playerID), attack that card. If he clicks on a tile, move it to that tile.
The problem: However, line 24-58 give me a bit of a problem. Right now, it works fine BECAUSE lines 46-58 are commented (which also means the unit can't move). If I uncomment those lines, the unit becomes able to move, however, lines 34-46 cease working...
Java Code:
@Override public void mouseClicked(MouseEvent e) { mainloop: for (int i = 0; i < Main.cards.size(); i++) { Card c = (Card) Main.cards.get(i); if (Card.cardSelected == null) {// Contains / Is not selected if (c.contains(e.getX(), e.getY())) { Tile.reset(); Card.reset(); Card.cardSelected = c;
I'm working on a spreadsheet-like table and I was able to set it so that it would highlight the first cell in the relevant row(titled 1,2,3.. etc) when a cell is clicked. (Just like in MS Excel - preview attached) Now I want to do the same to the column header(i.e. A,B,C,D....etc) . How can I do it?
private void formWindowOpened(java.awt.event.WindowEvent evt) { setLocationRelativeTo(null); int rowNum = sheet.getRowCount(); for(int i=0; i<rowNum; i++){ sheet.setValueAt(i+1, i, 0);
This is an old project that I had working probably 2 years ago. Since I reopened it the only thing I have changed is the database location. This is a very basic project I did to dip my toes in to Java. I'm going to add it to my portfolio but just to clarify I am not a Java developer so this is mainly there to show that I am not completely blind when it comes to Java.
Errors when I click the button that launches the JFrame:
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 6 >= 6 at java.util.Vector.elementAt(Unknown Source) at javax.swing.table.DefaultTableModel.getValueAt(Unknown Source) at javax.swing.JTable.getValueAt(Unknown Source) at javax.swing.JTable.prepareRenderer(Unknown Source) at javax.swing.plaf.basic.BasicTableUI.paintCell(Unknown Source)

It will launch the window but it will be blank. If I resize the window it will show me the headers. If I click below the headers were the data should be, it will show me the data.
Since it has been so long the only thing I can think of is some of the code has become antiquated. As I said, this was working originally. I just fired it up again to take some screenshots for my portfolio.
