ProgressMonitorDialog during viewer.refresh() [message #726684]

I have quite big table with columns (more than 10 000 elements) and I provide sorting for each column. After setting sorting column and comparator parameters I need to refresh viewer. This operation take some time and I want to add any progress indicator, but refresh() method block UI from beginning to the end of refreshing, application hang for a moment. Any attempts to resolve this problem was unsuccessful. Is there any way to refresh viewer partially? Or maybe there is other way to refresh viewer after setting comparator.

I will be greatfull for any hint Smile

The most time cost is to calculate the sequence of the TableItems .

so I think you can use a job, when the job compolete then refresh the view.

Unfortunately I have used ViewerComparator to sort items. Comparator is triggered when viewer is refreshing so from my point of view I only start refresh() method. Operation is not divisible. Probably I can manually sort my data set and put it into viewer, but right now I have no time for this and I am looking for easier fix Wink

In case 2 the sorting and filtering wont work,u have to do the sorting and filtering on the model and do the set input again(which by the way u can do in a job)

In case 1 i am not sure if thats the case,try it out.
