Update of JProgressBar

java-programmer, Update of JProgressBar Hi,

in my program i use a JProgressBar. I know, that i have to use another
Thread for updating the progressbar.
But with the following code it isn't working. What's wrong?

public class Parser1CheckVisitor{
int iCount = 0;
JFrameJRespCheck m_JFrameJRespCheck;
ResponseFile m_ResponseFile;

public Object visit(ASTrecord node, Object data) {
if (data != null) {
m_JFrameJRespCheck.jProgressBarPanelStatus.setMinimum(0);
m_JFrameJRespCheck.jProgressBarPanelStatus.setMaximum(m_ResponseFile.
m_iCount);

makeProgressThread().start();

for (iCount = 0; iCount < m_ResponseFile.m_iCount; iCount++) {
m_ChipFile.readRecord(iCount + 1);

data = node.childrenAccept(this, data);
}
}
return "OK";
}

Thread makeProgressThread() {
return new Thread() {
public void run() {
while (iCount != m_ResponseFile.m_iCount) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {}

m_JFrameJRespCheck.jProgressBarPanelStatus.setValue iCount);
//System.out.println(iCount);
}
}
};
}
}

java-programmer >> Update of JProgressBar It is not clear how the members m_JFrameJRespCheck and m_ResponseFile
are instantiated and initialized. Have you removed these lines from
your example ?

java-programmer >> Update of JProgressBar OK, i have it.
Within the while loop in the thread i have to invoke
m_JFrameJRespCheck.jProgressBarPanelStatus.update(m_JFrameJRespCheck.jProgressBarPanelStatus.getGraphics());

That's all.
