I would like a small box to be able to enter a contacts information and I started with building it thru netbeans. Now I am thinking I should start from scratch so I understand everything. What should I do? I am having trouble making the buttons at the bottom work. All I would like to be able to do is setFrameVisible(false); but I can't seem to be able to do that without loosing the whole project not just the frame I am working on.
The buttons I am referencing are the Cancel & Accept
public class pa4GUI extends javax.swing.JFrame
{
String ph;
String ln;
String fn;
String em;
String or;
I am developing a program in netbeans forms. I've got to a point where I will click a jButton to print the content of either JFrame or JPanel. I am using Netbeans forms to develop the project....
I want to create a jsp where there is a textbox and the user can change font styles (such as bold, italicized, underline, change color, change font style, highlight align a word/s) inside the textbox just like an MS Word. I'm not looking for a system similar to code ranch's posting of message which displays the tag in a textbox...
I am wondering if there is something similar to the "Find and Replace" action, that we use in applications like Eclipse and MS Word, that is actually built into the Java API so we can use it in our code, mainly for method names?
For example, right now I have these couple of lines
that does one operation for a side of Rubik's cube. However, all other sides of the cube can use these same exact code with the exception of the 2nd word, ie the position, in each method.
So for example, another side would do something, like, lets say
The reason why I ask this is because this would DRASTICALLY shrink the size my code, rather than have to create separate methods for each operation. Now I know there is a Find and Replace feature for Strings, but I am not sure about method names...
my IDE doesn't seem to recognize that my program is a Swing app.I get the following error message when I run the app: "jtabledemo.JTableDemo class wasn't found in JTableDemo project."It compiles successfully though.Here is the code verbatim:
ActionPerformed and ActionListener on Netbeans...If I create a ComboBox on Netbeans using GUI design, then I right click over the Combobox I can find Events - Action - ActionPerformed... but I can't find ActionListener...
Are ActionPerformed and ActionListener the same?
or...
where is ActionListener on GUI Netbeans? Do I need to manualy write the ActionListener part?
I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:
I'm trying to use netbeans GUI creator to create a chessprogram. However, the default "freeflow" layout is very difficult to work with. However, when I switch the layout to gridbag or border layout, I can't figure out really how to do anything. I don't know how to resize or position elements. Any good set of tutorials for using netbeans GUI creator with non standard layouts?
(I originally used absolute layout, which I can easily add and position elements in, but which I abandoned because i want the chessboard squares to resize when the window changes size).
I am still learning how to perfectly use the netbeans palette. I just created a GUI and want to use jTable on it. I have also dragged and dropped jTable component on my GUI. What should I do thereafter? My aim is to allow user input figures into cells, sum up the figures and enter same into a database. I have not used jTable before in java.
I am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.
I've used Netbeans IDE to create a simple Swing JFrame container, class NewJFrame.
NewJFrame calls another JFrame with dialog in it. Problem is there is an endless call made to it. Here's the issue relevant piece of code:
//Code for calling class package p; public class NewJFrame extends javax.swing.JFrame implements ActionListener { ......... public NewJFrame() { initComponents(); //IDE auto generated code for binding
[Code] ....
I searched but i cannot understand why run class is getting called multiple times. I have attached the screen prints for both the screens. 2nd screen print(of called class) is very shallow since screen was blinking unstopped due to multiple calls, but i have attached a faint image of it.
Create a Java Application in NetBeans with the following two classes.
1. A Java class College o Use the following data fields: College Name College City Number of Tracks Number of Students Number of Faculty Number of Staff o Implement an empty constructor o Implement a full constructor o Implement Setters and Getters (Mutators and Accessors) o Implement SetAll() method with all data members as parameters
2. Another Java class called CollegeDemo with the main() method: o In the main(): o Read the values of the fields of 3 colleges from a text file and for each create a College object. Filename: colleges.txt IT Dubai 7 200 50 20 ENG Abudhabi 4 400 60 20 SCIENCE Sharjah 3 300 40 20 First with empty constructor then uses setters. Second with full constructor (no need to use setters). Last one with empty constructor and SetAll() setter. o Display the average number of students for all the 3 colleges. o Change the value of ‘Number of Students’ in the SCIENCE College to 500, and display the average number of students again.
here my code :
public class Demo { private String name ; private String city; private String cname ;
I'm developing an SE Java application which allows the user to view a database that I've created. I've done the data binding to a JTable but don't see any data. I've read the Derby/Java DB manual and it seems that I need to put data into this Embedded database (single table). All I want to know is how to put the data in - can I copy the files from '.netbeans-derby' folder or do I have to utilise another method?
I have two JComboBox the first contains a list of patients, the second a list of antibiotics I want to make a button when I chose an antibiotic and a patient they will be added in my database (sql server)
I would like to use java se api names like, undo, redo, stylededitorkit, htmleditorkit in editorpane swing. So, I don't understand how to use these apis.
The naming conventions for coding Java applications are clear to me. I'm wondering what the best practices are for naming Java projects e.g. when creating a new project in NetBeans IDE or in BitBucket?
I have a couple .java examples I want to mess with but don't know how to get them into Netbeans so I can work with them. What is the process in loading a .java into Netbeans so I can work with the code and run it in Netbeans?
I am trying to create a program in NetBeans GUI builder and I am having trouble creating the 2D array. Here is what I have come up with so far:
private void enterButtonActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: double time = 0; try{ time = Double.parseDouble(timeText.getText());
[Code] ....
Right now it is printing what i need but I need to separate columns, not rows.
Currently the while near the end is not working in netbeans. It is saying illegal start of type. This whole section was working before when it was within the public static void method. I moved it to a separate class to try and clear up a, static variable problem. My question is can i fix it to keep it structured this way. Or do I have to put it back into the main method and try to work out the static variable problem a different way.
public class InventoryProgram { double[] dvdprice; // defines variables int[] dvdnum; int[] dvdstock; String[] dvdnames; int count; double total;
I'm working on a University project creating a simple game using Netbeans but I'm totally stuck. I've created a number of classes to perform various methods, such as throwing back formatted text but I can't get them to work from within a Swing GUI created in Netbeans.
The Main method simply creates an instance of another class called Game which then itself creates instances of a number of other classes (textEngine, timer) and also a Swing GUI Class. The GUI appears on screen ok and I've been able to get methods working inside the GUI such as changing pictures and text when clicking a button. But I CANT get the GUI class to recognise the instances of the other classes or access their methods. I've created an instance of the TextEngine class called tEng. So I type this code in the GUI class:
textField.setText(tEng.getPhrase(2));
getPhrase() returns a String based on the number passed in the argument. But Netbeans reports an error that tEng is not recognised as a symbol despit it being a member of the same package. Creating the instance of the class within the GUI class likewise fails:
