JTextArea content is not displayed

[deepsree1417]

Hi,

I tried to display some text in JTextArea. but its not displayed , but when i did System.out.println(JtextArea.getTeaxt()) the content is displayed in the output window.

Can anyone find the mistake in the code?

Here is the code...

public void scanner(File f) throws Exception
{


int worm_count=0,file_count=0,dir_count=0;

String file_name;
File[] listoffiles = f.listFiles();
String pathforworms = "C:/Documents and Settings/Srudent/My Documents/NetBeansProjects/securenet/WormList.txt";
File wormlist = new File(pathforworms);
BufferedReader br = new BufferedReader(new FileReader(wormlist));
for(int i=0;i<listoffiles.length;i++)
{
if (listoffiles[i].isFile())// for checking wether it is a file or not
{
file_count++;
file_name = listoffiles[i].toString();

//outwindow is the name of textarea
outwindow.setText(outwindow.getText()+ "\n Scanning ..... "+file_name);
Thread.sleep(100);

System.out.println(outwindow.getText());
while(br.readLine()!=null)
{
String name = br.readLine();
// System.out.println(name);
if(file_name.contains(name))// if it is a file then checking its name from
{ // the list
worm_count++;
outwindow.append("\n Worm Detected of the type"+name);
listoffiles[i].delete();
outwindow.append("\n Worm has been deleted");
}
}
}
else if(listoffiles[i].isDirectory()) // this is to check wether its a directory or not
{
dir_count++;

outwindow.append("\n Now scanning .."+listoffiles[i].getName());
scanner(listoffiles[i]);

}
}
}

Thanks

Here is the code...

You didn't post the code that's the cause of the issue. To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates the problem. Not all your code.

Two likely candidates: (1) the JTextArea you're appending to isn't the one displayed in the GUI or (2) calling sleep(...) on the EDT.

thanks sir...

i confirmed the control name . and i removed the sleep() also.
but still the problem exists.

outwindow.append("\n Scanning ..... "+file_name);

i gave this statement to display the contents in the textarea.

So where's that SSCCE?

edit
1) Java doesn't have 'controls' -- there are AWT and Swing components
2) A component doesn't have a name, unles you set one via the setName(...) method
