I am relatively new to java. . I cannot...(actually do not know) how to change the actionlistener (actionPerformed) after the second click in an array of JButtons. This is how the program performs right now.
On the 1st click on the grid, the border of the button clicked will change to 'blue' and another button will change its boarder to 'red'. on the next click the same action is performed.
What I need is to change action when the 'red' bordered button is clicked, lets say change the color of the buttons from the 'red' to the 'blue' buttons.(x 3 buttons).
The logic about how to perform the final result I think I can do on my own but my problem is how to change the action when the red bordered button 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?

I'm nearing the final development stages of my first game, but have run into a problem. I've constructed 4 different levels and allow the user to select the level they want to play from a central JPanel in a Card Layout system. My problem is that once a level is completed, I can't switch the JPanel which is displayed to start the next level, since I don't know how to access the original JPanel which acts as a driver for the other panels.

e.g User types: color blue
Then the background color of the console should turn blue
Is this possible and how would I go about doing it?
I am creating a JSP page with a html table to display employee directory. This is scriptlet :
<%
List<Employee> list = new ArrayList<Employee>();
PhoneListController controller = new PhoneListController();
list = controller.getAllContacts();
for (Employee eachEmp : list) {
%>
and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)
I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).
How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.

View Replies View RelatedWhat I'm trying to do is basically draw a Rectangle outline through left-click and then dragging the mouse to the size one wants.
After one has created this rectangle, the user can change the color of the rectangle through clicking the 3 sliders found on the top in the program. Upon the change in color, the rectangle should change from "g.drawRect" to "g.fillRect" and use the desired color.
I have the basic outline of the program done, but working with the last part (the color and changing of the Rectangle type after changing the color)
Is there like a "then" command in Java? Like: after you've done x, do y. That would make this heaps easier.

I'm facing a problem in controlling the focus traversal mechanism inside a jframe...as i want the focus to travel from top to bottom by pressing tab key regularly , but it travels left to right and then top to bottom through the textfields... The form looks like
textfield1 textfield4
textfield2 textfield5
textfield3
The focus travels from 1 to 4 , 2 to 5 and then rests at 3. but i want it to be like from 1 to 2 to 3 and then 4 and 5....

package event;

I have to implement the methods for what is happening if on some panel the action selected are Remove/Move/Change/Resize (Draw is already implemented).
The Applet in question draws ovals or rectangles on the screen and you can change the fill-color and outline-color of the shape. All this works already. I have dabbled with the move-method, but am not going anywhere.
This code will not dismiss the MemoryDateDialog when it loses focus, while it is what it is intended to do.
btnMemoryReason.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent e) {
List<MemoryDates> lMemoryDates = db.getMemoryDates(custID);
final MemoryDateDialog mdd = new MemoryDateDialog(lMemoryDates);

the focus traversal policy (hereafter "tab order") in forms and panels doesn't follow the order in which controls were inserted into the container, but is derived from the position of the components on the form or panel. This is very neat (and probably allows sloppy coders and GUI builders to exist without actually ever thinking about the tab order), except when it isn't. As when you actually want to specify a different component order, for example.
In the following example, I've created a form with two columns of buttons. I want the tab order to go through the first column of buttons, followed by second column of buttons (ie. a column-by-column schema). The default tab order is row-by-row, however, and can be obtained for reference by commenting out the setupFocus() call in the constructor.
I had hoped that the ContainerOrderFocusTraversalPolicy would do the job, but there is a couple of problems (which I've addressed in the setupFocus() method). Firstly, the container itself is part of the focus chain. This at least is easily remediable by calling setFocusable(false), but I don't have to do that with the initial focus traversal policy, so I wonder why I have to do it with this one. The other problem is more pressing, though - the ContainerOrderFocusTraversalPolicy lets me (un)hapilly tab through JLabels. Again, I've fixed this, but the initial policy knows all by itself that it's not a good idea to focus a JLabel. Moreover, I'm afraid there might be other components that do not receive focus with the original policy, but ContainerOrderFocusTraversalPolicy might plod though them.
isn't there some focus traversal policy implementation that I could just set and it would tab through exactly the same components as the original policy, except it would order them according to their order in the container?
