Button Question/Issue

Question

16 Years Ago

I currently have a program using keyboard input from the user, but am trying to replace keyboard input with onscreen buttons. Does anyone have any information on the best way to do this? I've pasted the code file involved with this (there are other files in the program). I'm not very familiar with java so what I'm finding so far is a bust (some of my attempts are commented out in code). Thanks in advance to anyone able to shed light on this!

Decide where you want to put the buttons on the GUI, place them there, and add ActionListeners to them. Each new button represents a key that was pressed before. Decide which buttons go with which keys. Say a button called kButton was assigned to do the same thing as what used to happen when the user pressed K on the keyboard. Somewhere in your old code you have a KeyListener and a keyPressed function to go along with it. Within that keyPressed function, some code exists to handle what happens when K is pressed. Copy that code and put it into your new actionPerformed function. Somewhere within actionPerformed you'll want to have a block of code to be executed if kButton was pressed. Paste the code that you just copied from keyPressed into there.

public void actionPerformed (ActionEvent e)
{
     if (e.getSource () == kButton)
     {
          // paste code from keyListener here
     }
     // code to handle other events
}

If it's a class that you CAN add a button to, it'll be something like this:

kButton = new JButton ("K Button");
add (kButton);
kButton.addActionListener (this);

This particular example comes from code where I created my own class called "Proj1Component", which extended JComponent and implemented ActionListener. I added a JButton called "kButton" to "Proj1Component". An instance of "Proj1Component" was added to a JFrame. This code is from the Proj1Component constructor. kButton is defined in Proj1Component outside of any functions.

This tutorial has examples of working with the available layout managers: http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html

You can probably use a BorderLayout for the main frame with your main panel in CENTER and a button panel in SOUTH. The button panel could use FlowLayout or GridLayout perhaps. Neither of those is too complex.

GridBagLayout would be more flexible, but it can take a little work to get comfortable with it.

Thanks, but here's the kicker: HOW do I add the button?? I'm sorry to say I can't get a button to show up on screen at all.

OK, I have one giant button coming onto the screen, but it's behind the display screen. What's the best way to get the buttons to show up at the bottom of the screen? I'm thinking some sort of layout manager will be the best way, but not sure how to get it to work.

This tutorial has examples of working with the available layout managers: http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html

Thanks, I'll go through that. Was looking at a diff one, but my main concern is button size; don't want the buttons to be huge on the screen.

You can probably use a BorderLayout for the main frame with your main panel in CENTER and a button panel in SOUTH. The button panel could use FlowLayout or GridLayout perhaps. Neither of those is too complex.
GridBagLayout would be more flexible, but it can take a little work to get comfortable with it.

So basically 2 Layout managers are involved, one for the main screen, and another for the controls; that should work. already coding out the FlowLayout for the buttons. Cool, I'll try that. Thanks.

Cool, thanks. Good to know about PreferredSize control too. As for doing a layout for both the display screen and for the buttons, can I set that within the related panel, or do I have to set it up from a seperate panel? Specifically, if I have a panel named FireworksPanel that displays the game, can I setup the layout from within FireworksPanel to place it on North and the controls on South, or would I have to do that within a different panel?

Each panel can keep all of it's layout setup completely internal (and should). The code that puts together the main frame should place the panels wherever they need to go.

Edit: Fireworks panel can still have as many internal panels as it wants to group components together. The main frame can still just treat it as a single component. If FireworksPanel has two internal panels, one for the screen and one for buttons, that won't affect the main frame at all. You don't have to put each piece into the frame - panels can have panels within panels within panels ad nauseum, so don't think each piece has to go into the top level container.

OK, I'm trying to add the buttons as discussed (place the buttons down below display). 2 questions:
1) How would I set the display to be its own panel seperate from the buttons (or should I just have the buttons be its own panel layout and stop there)?
2) What I have below seems to have some sort of issue, as I can no longer see the score, or execute the rest of the program. What am I doing wrong?
