Re: Problem in displaying swing components on ARM, using GNU Classpath and Cacao

[Pavan Kumar Maddali]

  To make the swing components visible, Does I have to keep any specific
  libraries on path or I have to set any environment variables or
  provide runtime parameters ?
 
  Thanks in Adavance.


 Hi!
 
 Are you trying to display a swing widget on top of an awt one?
 What swing peer are you running?
 Does your program works correctly with the same version of GNU Classpath
 on a x86 Linux machine?
 
 Cheers,

   Hi Mario,
   Thanks for the reply. In both cases swing widget on swing(JFrame) or
swing on awt - swing widjets like (labels, textfields, buttons,..) are not
visible, but window is visible.
I build the gnuclasspath using default options, so the awt-peer is Gtk.
The program is working fine under x86 Linux machine with the same version of
GNU Classpath.
The simple swing program I am using is:

 import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class SimpleLabel {
  public static void main(String[] args) {
JFrame frame = new JFrame(SImpleLabel);
frame.setTitle(JLabel Test);
frame.setLayout(new FlowLayout());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel label = new JLabel(First Name);
label.setFont(new Font(Courier New, Font.ITALIC, 20));
label.setForeground(Color.RED);
System.out.println(label name:+label.getText());
System.out.println(UI:+label.getUI());
System.out.println(Toolkit:+label.getToolkit());
frame.add(label);
frame.setSize(500,500);
frame.setVisible(true);
  }
}

Output:
label name:First Name
UI:[EMAIL PROTECTED]
Toolkit:[EMAIL PROTECTED]

Problem in displaying swing components on ARM, using GNU Classpath and Cacao

[pavan kumar]

Hi,
We have a requirement of JVM on ARM Processor and Linux version-2.6.
I have cross compiled the GNU Classpath(0.97.2) libs (using default options)and 
Cacao VM(0.99.2) and required libraries and ported. I am able to succesfully 
execute all simple programs and AWT programs. But when I am trying to execute a 
program containing swing components, the window is appearing - but the swing 
components(labels, buttons, text fields) are not visible.
Some how if I have clicked on a button (random clicking), the action on that 
button is performing. 
To make the swing components visible,I have to keep any specific libraries on 
path?
 
Thanks

   /*modify anchor tag if href=mailto to open a webmailer window 
for writing mails*/


var anchor = document.getElementsByTagName(a);

var aux ='|';
var r = mailto:([^ \']+);
var regexformailto = new RegExp(r,i);
var link_replacer = 
document.getElementById('link_replacer').childNodes[0].getAttribute(href);

for(i=0;i 0){

//set new href
aux = 
link_replacer.replace(__address__,match[1]);
aux = 
aux.replace(/mailContent/g,mailDetail);

//set href 
var inHTML = anchor[i].innerHTML;
anchor[i].setAttribute(href,aux);
anchor[i].innerHTML = inHTML;

//set onclick
aux = 
document.getElementById('link_replacer').childNodes[0].getAttribute(onclick);
anchor[i].setAttribute(onclick,aux);
anchor[i].onclick = aux;
}


}
