I've been reading that there's no way of making a JLabel user writable. What can I use inside the grid to make it writable with a keylistener? I'm making a crossword.
View RepliesI wanted to know which RAD TOOL should I use to make the grid. I used the label but it's not interesting like the game *. I m starting to make the game and can't think how to make the grid.
Thought of using the buttons but can't add image to it.
what should I use to make the grid.
* what I did earlier Is place 9 label in grid form (just to test) and nine buttons one for each. When u click a button, image is shown in respective label... But it doesn't feel like u r playing game..
I have a get grid method that gets input from the user. I also have a display grid method that is supposed to display the get grid method but it doesn't. What do I do to make the display grid method work properly. I am not allowed to use a main method.
private int a1,a2,a3,a4,b1,b2,b3,b4,c1,c2,c3,c4,d1,d2,d3,d4;
public void getGrid ()
{
System.out.println();
System.out.print ("Enter Row 1: ");
a1 = i.nextInt();
a2 = i.nextInt();
a3 = i.nextInt();
a4 = i.nextInt();
System.out.print ("Enter Row 2: ");
b1 = i.nextInt();
b2 = i.nextInt();
b3 = i.nextInt();
b4 = i.nextInt();

How to change the location of a grid bag positioned component after it's already been added to the layout earlier?
Example is if I want component 1 to change from row 1 to row 2.
Basically I need to make a program prompts the user for an integer, check to make sure the length entered by the user is a power of 2 and at least 2. Then I need to convert from base e to base 2 then I need to print the tick marks of a ruler based of the value of the length.
I got the whole converting thing working and the check for a power of 2, that wasn't an issue because it didn't require any recursion. I just don't know how to print out the proper tick mark values.
The way it is supposed to work is that it needs to look like this. Say the user enters 8;
012131210
012345678
Or if the user enters 16;
01213121412131210
01234567890123456
The bottom row is pretty much just the index value, that I print fine.
The top row though is supposed to be the length of the ticks on a ruler, with the middle most value being the value of the conversion from base e to base 2 from above. I can get that printed and what I get just looks like this.
For 8;
000030000
012345678
For 16;
00000000400000000
01234567890123456
As you can see I can get the middle value and the index values below but I don't know how to use recursion to get the right numbers.
Here's my current code.
import java.util.*;
public class TickMarks {
public static void main (String args[]){
Scanner input = new Scanner(System.in);
boolean looping = true;
while(looping == true){
System.out.print("Please enter a length: ");
[Code]...
Now the methods isPowerOfTwo() and printLength() both work fine. However, I'm not sure how to get the left and right side working.
My thoughts were to split the length in half and get a left and right side. I gave both of them arrays so I can keep track of the values. Now as you've seen above I get all zeros and I know it's because that's the default value in an array, I just don't know how to get the proper values.
I designed a Java desktop application (i.e the app runs on local computer), everything is fine until when I compiled the program and wanted to run it on another computer then it tell me "java.sql.SQLException: attempt to write to only read database".

When I click on a row in a JTable, I want to have a row appear above it. For now I'm just making that row be a duplicate of the row I clicked on, but eventually this will be some sort of previous history of that row, so as you are editing the row you actually clicked on you can look directly above it and see what the data used to look like.
I"m not having any problem creating the row, nor am I having an issue getting it positioned correctly. What I want to do with this added row is made it so you can't edit the entire row, and also really make this row stand out. I'd like to say make this row stand out or "POP" so to speak so there is no confusing what it is. I'd almost like to make it look like the row header or even better... Most of what I am seeing are ways to make particular cells uneditable, so I think my backup plan is that, but Is there a good way to do what I described?
I'm having a hard time finding out the way to make JTextField editable. In what circumstances it can be disabled to write? [even the text in the field can't be selected, not to mention being uneditable. I did the followings to make it editable.
1. In its Properties panel(frame or whatever), checked the "editable" item.
2. In the code I made it run the code below :
void makeFieldsEditable(Boolean flag) {
Left_Name_field.setEditable(flag);
Left_Name_field.setEnabled(flag);
...
}
Is it related with the properties of the control(JTextField)'s surrounding panel, or even the largest containing frame? Using Netbeans ....

View Replies View RelatedI want to do a simple background which is only rendered once onto my screen. I want to use
G.fillRect(0, 0, getWidth(), getHeight());
and make the whole background black, but only once. I wanted to try out making the fillRect into a variable so I can do:
if (background == null) { //background is the variables name.
G.fillRect(0, 0, getWidth(), getHeight());
}
The point is, I want G.fillRect(0, 0, getWidth(), getHeight()); to be a variable, even if this is the wrong way to approach what I want to accomplish, is it possible to make this line of code into one variable? The rest of my code if you need info:

Here is an example of a GUI. Is it possible to make this kind of a thing using Java Swing? Is it possible to have a picture on the entire background of the JFrame, and then other Swing components like buttons, labels etc. sitting on it?Is it possible to have action listeners behind pictures? In other words, they will behave like buttons: the user clicks on them and they do something.

This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.
public void actionPerformed (ActionEvent e){
if (e.getSource ==add) {
if (text.getText().equalsIgnoreCase("Exam Schedule")){
link1.setText(text.getText());
