Problem With Image Data And getImage(...) Function

Hi Experts,

Whether you open accidently say a .txt file in Image data using getImage(..) or whatever the case is this method always and immediately returns non-null. Even if the image is not FULLY AND SUCCESSFULLY loaded but because of this function immediate returning of non-null value, you can't trace whether there is really image data or whether the image is successfully and fully loaded or not.

I have also use mediatracker with th images after calling getImage(..), and used the mediatracker waitforAll() methods but many times mostly when number of images are more, it too doesn't give the desired results.

Is there any way that the control of the java-applet program doesn't go any further unless an until the Image gets fully and successfully loaded.

In my applet there are 15-20 jpeg's (not big), but always two or three are left out giving a bad view of the applet to the end user.

Best Regards
Austin

Thanks heyhey and bpouydog,

I will explain you things now after 4 days of long work. I too believed that mediatracker cannot work in a wrong way as you also quoted heyhey, But still the following problem is occuring with my code.

I have 8 buttons on my applet and each button has image(gif) over it, my code all in the init() method::

url1=getClass().getResource("button1.gif");
button1gif=getImage(url1);
url1=getClass().getResource("button2.gif");
button2gif=getImage(url1);
..... for all eight gif's, then

mediatracker1.addImage(button1gif,0);
mediatracker1.addImage(button2gif,1);
....... for all eight,then

try
{
mediatracker1.waitForAll();
}catch(InterruptedException e)
{
}
if (mediatracker1.isErrorAny()==true)
System.out.println("Yes Errors");
else
System.out.println("No Errors");

Console Prints that there are No Errors, after which I create buttons as ::

JButoon button1=new JButton(button1gif)
..... and so on for the rest buttons

But the gif's can be seen only in the last four buttons and not the first four. No doubt, apart from these images there are some more images which gets downloaded for my applet to work. But for all I have used the same technique ..

waitforall() and IsErrorAny(), and everywhere I gets "No ERROR". Rest all images are fine. The problem is with the gif's of the FIRST FOUR BUTTONS. ALSO THE PROBLEM IS NOT ALWAYS. FEW TIMES THEY ALL GETS DOWNLOADED say 1 out of 4.

I don't know why this is happening, Please see to it.

Best Regards
Austin
