Dialog while calling method

Support
#1

Hello,

I’m trying to generate a dialog whith a progress bar with style “indeterminate-circle” while a method is running.

This is my screen xml:

<layout>
    <progressBar id="loading" width="100%" indeterminate="true" stylename="indeterminate-circle"
                 align="MIDDLE_CENTER"/>
</layout>

The idea is:

1.- show the dialog: openWindow(“popup”, WindowManager.OpenType.DIALOG);
2.- call a method: reloadData(initDate, endDate); (with the dialog still visible)
3.- close the dialog when the method ends.

How can I do this?

If I write this code on my Controller, I get the following result:

1.- call the method reloadData
2.- when the method finish, the dialog is shown.

What I’m doing wrong?

Thank you.

Hi,

You should not perform heavy computations in UI event handlers. Instead you should start an asynchronous operation. Take a look at BackgroundTask API and BackgroundWorkWindow dialog:
