How To Show Changes To TUniStatusBar's Panel Text Immediately?

[Frederick]

I have a TUniStatusBar where I have one panel with a text of "Ready". When I click a button to perform some database processing (which takes about 2 seconds), I would like to change the panel's text to "Processing..." at the start of the process.

However, the panel's text never changes to "Processing...". What can I do to get the text of the panel to change immediately once the button is clicked?

begin
   UniStatusBar1.Panels[0].Text:='Processing...';   // This is not handled?

   // some database processing
end;

Hello,

Here are some solutions to this problem.

First:

UniMainModule.EnableSynchronousOperations > True

Thanks. Looking at the demo, it seems that I need to treat the database processing as a main thread and update the visual controls on the side.

I will explore this further.

BTW, my EnableSynchronousOperations property of UniMainModule is already set to True.

Thanks. Calling UniSession.Synchronize allowed the TUniStatusBar to show the new text.
