(0,0) (0,10) (0,20)
(10,0) (10,10) (10,20)
(20,0) (20,10) (20,20)
And we have a class that draws a rectangle of 10 pixel height and 10 pixel width at 0,0 coordinates.
And we want to move with the arrows the rectangle but not to go off the frame.
The question is:
How can I do that if I draw another rectangle, it knows where is the other object and they not collapse. And so on, they move, but not collapse, just touch and stop.

When I comment out the adding and setting of the pnlChart on my main driver, the pnlPopulationInputs shows up fine, and it runs ok. When I add the pnlChart I get errors like crazy and a white screen. My errors:

Scrolling In Panel Won't Work
Oct 9, 2014I've got a panel which an arbitrary number of text fields may be added to at run time. I've got it set up so that the window's height, and the height of the panel in which the fields appear will never exceed the height of the screen.What I don't have is a way to make the panel scroll to access the fields that are being visually truncated. I'm setting the autoscrolls on the panel to true, but when I run the program, the fields are simply truncated.
pnlDeclensions.setAutoscrolls(true);

Fill A Panel With Seats
Jun 13, 2014We get a database and some DAO classes. We had to fill a ShowPanel with different shows being given in a theatre, and then when you choose from this you get several dates. Then when you click a date, the seatings appear in the SeatPanel. I got the first part with the shows and dates. But Im stuck at getting the seatings.We have a controller class which calls the shows+dates (this happens in one method). But i always get a nullpointerexception for the seatings. (this happens in a different method). I think i just don't know how to link the chosen show+date with the seatings.For the moment i have
public ArrayList<Seats> getSeating() throws SeatingException{
Show s = shows.getName();
ArrayList<Showdate> showdate = s.getDates();
ArrayList<Place> seating = new ArrayList<Place>();
try{
for (Showdate sd : showdate ){
[code]...
The given class PlaceDao has a static getInstance() method and an ArrayList<model.Place> getSeating(model.Showdate showdate) method.In the next stage i have to try and fill the panel with the seatings, but first i need to be able to call them.

How To Get Object From Panel Back Across To GUI
Jul 6, 2014I've been putting together an addressbook and try to work on some idea but I have hit a bit of a wal early on, and Im sure the problem is easy to resolve, I just can't get the old brain to do it.At present I have 5 classes
PersonDetailsAdressDetailsAddressBookAddressBookGUIEnterDetailsPanel
I have taken EnterDetailsPanel out of the main GUI code, as I plan, or had planned on using additional JPanels for the other options of the application until I got stuck. What I want the EnterDetails panel to do, which it does so far is to have the user enter all of their information and when the button is pressed it will then create a PersonDetails object and here is where my problem is. how to get the object from the panel back across to the GUI which initalises the AddressBook class in the constructor and add it to the List via an addDetails() method.
If I create a quick method in the AddressBookGUI class I can add the object to the List fine, I'm guessing this is because I have created a new instance of the AddressBook in here already via the constructor, however if I add an AddressBook reference in the EnterDetailsPanel I get a nullpointerexception for the opposite because it's not been created in there.These are what most of the classes do so far.
PersonDetails has a reference to the AddressDetails and holds all information for that person.AddressBook contains a List that accepts PersonDetails and has methods to add/remove the person.AddressBookGUI creates a new instance of the AddressBook class along with the general gui things. EnterDetailsPanel is added to JTabbedPane in the GUI class and allows the user to enter their details and submit those via a button which will then create a new PersonDetails object that I am trying to get added to the AddressBook class List

View Replies View RelatedGUI - Calling Int And Double Values From One Panel To Another
May 10, 2014So I am making a panel project that calls three panels. Panel one holds all information and the other two panels are panels that open up when I press a button. How it works is I call the first panel, press a button, second panel opens. Then in the second panel I plug in a password. If it is correct, a third panel will open. I need to call values from the first panel into the third panel and those values act as sort of like counters. In the third panel it will display all the counters that were added as well as the complete sub total, tax, and total that the program accumulated during its run time duration. I know how to use constructors, accessors and mutators, but the values I need are generated in an event when I press a button. I am trying to figure out how to call those values from the event into the third panel. Here is my code :
Main Class:
import javax.swing.*;
public class AppleRegister {
public static void main(String[] args) {
double subTotalp2 = 0, taxP2 = 0, realTotalp2 = 0;
JFrame frame = new JFrame("Apple Crazy Cola Cash (Apple IIC) Register");
[Code] .....
Here is the main panel holding the information. The counters counterp21 through p24, subTotalp2, taxP2, and realTotalp2 are the values that need to be carried over to the third panel and displayed in the textfields. I will post half of the panel, at least the important parts. Notice that I made my constructor initialize double variables which are the subTotalp2, taxP2, and realTotalp2. In this instance, I am not calling the counters just yet due for the sake of testing purposes. TempListener2 is the event that holds the variables that I am trying to call into the third panel.
Main Panel:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.DecimalFormat;
public class AppleRegisterPanel extends JPanel {
private JButton button1, button2, button3, button4, button5, button6;
[Code] ......
And here is how I am trying to call those values into the third panel. If you notice, the class is actually called AppleRegisterPanel2; this is because I made this before the second panel that is now implemented. This panel now acts as the third panel.
Third Panel:
public class AppleRegisterPanel2 extends JPanel {
private JButton b1;
private JTextField t1, t2, t3, t4, t5, t6, t7;
private JPanel panel, panel2, panel3;
private JLabel l1, l2, l3, l4, l5, l6, l7, l8, l9;
private double subTotalp2, realTotalp2, taxP2;
[Code] ....
So my question is; is what I am trying to do even possible? I know the information that is being stored is inside a void that is acting as an event. As it stands the code that is called in the third panel is 0.0. I know this code seems sloppy but I've been trying different things with no result. How I can do this if at all?
How To Hide A Panel But Preserve The Space
Mar 27, 2014I have eight panels that are one above the other and are the full width of the frame.
I would like to hide some of them some of the time and then "bring them back".
If I use panel1.setVisible(false) panel1 will disappear but then all the panels below it move up to take panel1's place.
I don't want that to happen. I want just a blank area where panel1 was.
Is there a way to do that?
JSF :: PrimeFaces Accordion Panel Information
Aug 13, 2014I have an JSF that uses primefaces accordion snippet. However I want to populate the information from each tab from a seperate webpage that would also have accordion snippet in it. I can do this on a single page no problem, but the length of the program (webpage) is getting to the point that it is unmanageable.
The code I have:
<p:layoutUnit position="center">
<p:accordionPanel activeIndex="null">
<p:tab title="Burglar">
<h:outputText value= "Burglar"/>
<p:accordionPanel activeIndex="null">
<p:tab title="Skills">
<h:outputText value= "Skills"/>
[Code] ....
What I am after:
<p:layoutUnit position="center">
<p:accordionPanel activeIndex="null">
<p:tab title="Burglar">
<h:outputText value= "Burglar"/>
<p:accordionPanel activeIndex="null" url="burglar.xhtml">
</p:accordionPanel>
[Code] ....
How to get this to work... I am sure that it has something to do with my url but not sure how to fix it and I can not find anything on the web on how to do this.

Enable / Disable All Textboxes In Panel
May 31, 2014I am learning Java but have a strong C# background. I am trying to figure out the syntax to do this in Java. In C# I would do the following to enable all text boxes in a panel
private void EnableAll() {
foreach (Control ctrl in Panel1.Controls) {
if (ctrl is Textbox)
((Textbox)ctrl.Enabled = true;
}
}
Is there something similar I can do in Java to do the same thing.
