Gui Help ( toolbar )

Expand Post »

Greetings,
Ive came across problems while doing a tutorial work piece.

i've to design a toobar ( yup a JToolBar ) with 5 buttons inside it, that will do certain functions for a JSlider.( set them at certain values )

Its simple enough to go and write 5 buttons into my code, but thats not wot ive to do.

Quote ...

The idea is that you will
develop one button that is customisable at design time to have one of 5 different
appearances. Developing 5 separate buttons is NOT an acceptable solution.

Is this even possible? ( pls note the 5 different appearances are Symbals )

Problem: Placing 5 buttons inside a JToolBar, and positing it under my created JSlider

Re: Gui Help ( toolbar )

Sure it's possible. You just have to correctly read your assignment.

Putting a JToolBar anywhere except on the edges of a window is however NOT possible.

Re: Gui Help ( toolbar )

I looked through some of my old codes, and found something i thought would be useful.

Upon editing it i came up with this

Java Syntax (Toggle Plain Text)
import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JToggleButton;
import javax.swing.JToolBar;
 
public class ToolBarTest {
  public static void main(String args[]) {
    JFrame frame = new JFrame();
    Container contentPane = frame.getContentPane();
    JToolBar bar;
    bar = new JToolBar();
    JToggleButton jb;
    for (int i = 0; i < 5; i++) {
      jb = new JToggleButton("" + i);
      bar.add(jb);
 
    }
    contentPane.add(bar, BorderLayout.SOUTH);
    frame.setSize(300, 300);
    frame.show();
  }
}
import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JToggleButton;
import javax.swing.JToolBar;

public class ToolBarTest {
  public static void main(String args[]) {
    JFrame frame = new JFrame();
    Container contentPane = frame.getContentPane();
    JToolBar bar;
    bar = new JToolBar();
    JToggleButton jb;
    for (int i = 0; i < 5; i++) {
      jb = new JToggleButton("" + i);
      bar.add(jb);

    }
    contentPane.add(bar, BorderLayout.SOUTH);
    frame.setSize(300, 300);
    frame.show();
  }
}

So far my attempts to implement it into my code have failed.
Could anyone give me pointers? ( in my first code im using the light layout functions ( UI ) im afraid thats all ive been taught in so far

Re: Gui Help ( toolbar )

That isn't what you're supposed to do.
Think subclassing the button to create one that has a custom constructor taking an argument telling it what incrememt or decrement it should apply to the slider and another argument passing a reference to the slider.
