gadio: you are right. My loop is within an event handler. It actually occurs after a button is clicked. But I cannot figure out a different structure... Is there any suggestions from you? <br />

<div class="content wysiwyg-content">
Hi,<br />
<br />
&nbsp; My code has the following structure:<br />
<br />
for(int i = 0; i &lt;&nbsp;10000; i++) {<br />
&nbsp; do some calculation;<br />
&nbsp; drawCanvas.repaint();<br />
}<br />
<br />
What I want is to do some calculation and plot the progress, and so on. But it seems that only after the loop is finished, the my &quot;drawCanvas&quot; is repainted(WM_PAINT message is blocked). May I know how to force painting? In MFC, we can use GetClientDC() to obtain a graphic device to draw on. Is there anything similar in Java? By the way, I need this to be done with JDK1.0.2 for maximum compatibility.<br />
Thanks for your time.<br />

Hi,

  My code has the following structure:

for(int i = 0; i < 10000; i++) {
  do some calculation;
  drawCanvas.repaint();
}

What I want is to do some calculation and plot the progress, and so on. But it seems that only after the loop is finished, the my "drawCanvas" is repainted(WM_PAINT message is blocked). May I know how to force painting? In MFC, we can use GetClientDC() to obtain a graphic device to draw on. Is there anything similar in Java? By the way, I need this to be done with JDK1.0.2 for maximum compatibility.
Thanks for your time.

how to force repaint()?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
