Interface ProgressListener
- JiuAwtFrame
public interface ProgressListener
This interface must be implemented by classes that want to be notified
about progress of an image operation.
void | setProgress(float progress) - Set the progress level to a new value, which must be between 0.0f and 1.0f
(including both of these values).

void | setProgress(int zeroBasedIndex, int totalItems) - Sets a new progress level.

setProgress
public void setProgress(float progress)
Set the progress level to a new value, which must be between 0.0f and 1.0f
(including both of these values).
You should not call this method with a value lower than any value you've set
before.
However, this is not checked.
progress
- the degree of progress as a value between 0.0f and 1.0f
setProgress
public void setProgress(int zeroBasedIndex,
int totalItems)
Sets a new progress level.
If an operation consists of totalItems steps, which are numbered from 0 to
totalItems - 1, this method can be called after the completion of each step.
Example: if there are three steps and the first one is done, the parameters
must be 0 and 3, which will indicated 33% completion.
Parameters 1 and 3 mean 66%, 2 and 3 100%.
If you use 3 and 3, an IllegalArgumentException will be thrown.
Computes
(float)(zeroBasedIndex + 1) / (float)totalItems
and calls
setProgress(float)
with that value.
zeroBasedIndex
- the index of the step that was just completedtotalItems
- the number of steps in this operation
