Variable NumClicks Adds All Of The Button Clicks Together?
Oct 12, 2014
import javax.swing.*; //import javax swing package
import java.awt.*; //import java awt package
import java.awt.event.*; //import java awt event package
public class JPizzaSize extends JFrame implements ActionListener //class name
{
final int SMALL = 7;
final int MEDIUM = 9;
[code]....
My variable numClicks counts all of the clicks on every button instead of each individual button and adds the cumulative total to the JTextField. What have I missed? If I click button1 twice, $14 appears in the text field, then if I click button2, $27 appears in the text field instead of $23. I though that numClicks would stop counting at the end of the curly bracket for that block of code?
I have this piece of code, which adds marks into 2 different arrayLists, one for homework marks, and one for examination marks..
ArrayList<Double> homeworkMark = new ArrayList<Double>(); ArrayList<Double> examinationMark = new ArrayList<Double>(); boolean markCheck = true; do{ // the purpose of this try catch is to make sure that the entered mark is a valid number. If the program encounters an exception markCheck will become true and the loop will begin again asking the user to enter the marks. If the marks are all encountered correctly markCheck will be false and the loop will end.
try{ for (int i = 1; i <= amountAssignment; i++ ) { sc.reset(); System.out.print("Homework Mark for Assignment " +(i) + ": "); homeworkMark.add(sc.nextDouble()); System.out.print("Examination Mark for Assignment " + (i) + ": "); examinationMark.add(sc.nextDouble()); markCheck = false;
I have a bookings table where customers can view their bookings and in the table there is a button with a command button that onclick goes to the dialogue to display the variable petUpdate value but if you have 2 bookings then all the update buttons display the value of the last petUpdate in the arrayList.
DataTable with the button
<p:dataTable id="bookingTable" var="customerBooking" value="#{booking.sessionBookingList}" editable="true" style="margin:0px 0px 20px 100px;font-size:15px;width:600px;" >
Code in the above datatable.......The commented out output label displays the correct value for each but when the button is clicked the dialog only displays the last ones value
I have a class Tile that extends JPanel within the constructor for Tile I have set the opacity to false so that I can place tiles atop each other and see parts of the tiles below and the background through those parts of the tile that are not being drawn on. This implies that I am using paintComponent within Tile to display the image of the tile I want shown on this object.
The tiles are stacking perfectly. But I find that if I click on a tile through the transparent area of another tile, it is the top tile (transparent area) that retrieves the mouse click. This makes perfect sense, but is there a way to allow the mouse click to pass through transparent portions of the JPanel?
I've considered writing my own method to determine if the mouse click was within bounds then if it was outside the bounds of the object, find a way to pass the click event to the tile below. But this would be extremely challenging if the tiles were implemented as donuts (with holes in the center) or as some other obscure shape with transparent sections.
I'm creating a small program to count the number of mouse clicks the user is inputting into a BlankArea for a school assignment. I just finished with making the program look nice and all so I was putting in a MouseListener to detect the clicks. However, when I tried adding a MouseListener to the code, the error in the title appeared.
Java Code:
import javax.swing.*; import java.awt.*; import javax.swing.border.*; import java.awt.event.*; public class CountClick { JTextArea textArea = new JTextArea();
[Code] ....
Here's what's going on:
Compiling causes error as described in Title Java Code: createAndShowGUI() mh_sh_highlight_all('java'); cannot be referenced from a static context appears Java Code: public static void main(String [] args) mh_sh_highlight_all('java');
It contains the thread safe and program previously launched without mouse functionality(program appeared when there were no MouseListener components and thread safe had all static method stuff).
I have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
I am using JS, how we can make focus to a button during onload, the button need to get focus which is in tabbedPane tab Name : (Search Critera1) using javascript.
I have a JButton with a .PNG icon on it. I want to get that button click in actionPerformed Method but Jbutton have no Label... How i will know that which button clicked?
The term "Local variable" is related to scope. That is a local variable is one which is defined in a certain block of code, and its scope is confined inside that block of code.And a "Member variable" is simple an instance variable.
I read in a discussion forum that when local variables are declared (example code below), their name reservation takes place in memory but they are not automatically initialized to anything. On the other hand, when member variables are declared, they are automatically initialized to null by default.
Java Code: public void myFunction () { int [] myInt; // A local, member variable (because "static" keyword is not there) declared } mh_sh_highlight_all('java');
So it seems that they are comparing local variables and member variables. While I think a member variable can also be be local in a block of code, isn't it?
when we create another variable and set it equal to the first : Car c2 = c1;
we're pointing c2 at the same car object that c1 points to (as opposed to pointing c2 at c1, which in turn points at the car). So if we have code like,
Car c1 = new Car(); Car[] cA = {c1, c1, c1, c1};
are we doing the same? Are we creating four *new* reference variables, each of which points at the same car (again as opposed to pointing them at c1 itself)? I think so, but want to make sure I'm understanding this correctly.
I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
public class MadLibs { public static void main(String[] args) throws IOException { //////////////////// //TEXT PANE WINDOW// //////////////////// //Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane //designed especially for the editing (and display) of styled text. final JTextPane pane = new JTextPane();
I have a JFrame jf and JPanel jp on it. jp has five TextFields named cel1, cel2.. cel5. I wish to construct a String Cel + for loop index and run a for loop to reset the values of all the text fields using a single statement such as cel1.SetText("abc"). Similar things can be done in foxfro. How does one do it in java?
I dont know why this does not work. A string called naam is empty in the beginning. Thats why its NULL on the button. But if I give it the value "karel", it still states null on the button, how can I update this?
Im trying to use num as the text on the button..... (Im trying to make it count when i press the button.)I need to make a listener for the button, and an event that adds 1. (num++)
import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.*; import javax.swing.*; public class ClickIt { public static void Practice()
public void actionPerformed(ActionEvent ae){ float A=0; int a = Integer.parseInt(tf1.getText()); if(ae.getSource()==b2) { A=(((30*a*14) / 100)+(30*a));
I have gotten the code up and running, now I am trying to add a previous button. The next button I have now works fine but I can't seem to get the previous button to work.
import java.util.Scanner; class Sum { public static void main(String[] args) { int sum = 0; System.out.println("Please write a number, end with ESC button"); Scanner in = new Scanner(System.in);
