How to Make the total work of SubMonitor as IProgressMonitor.UNKNOWN in eclipse RCP?

Question

I have created SubMonitor by SubMonitor.convert(monitor,IProgressMonitor.UNKNOWN ). Even though i am providing the total work as UNKNOWN, internally it assigns 1000 as total number of ticks(refer SubMonitor.java). how to make the total work as UNKNOWN in this case?

Answer 1

SubMonitor doesn't really support unknown progress.

You can either stick with just using IProgressMonitor and not converting or you can use code like this:

void unknownProgress(IProgressMonitor monitor)
{
    SubMonitor subMonitor = SubMonitor.convert(monitor);
    while (hasMore())
     {
        // Use 1% of the remaining space for each iteration
        processNext(subMonitor.setWorkRemaining(100).split(1));
     }
}
