QLineEdit update before external method

[Ishtar]

Greetings All

I have something like the following in my project.

MainRoutine doStuff;
 
QLineEdit test = new QLineEdit();
test.setText("Updating...");
 
doStuff.runSTLcppRoutine();

MainRoutine doStuff;

QLineEdit test = new QLineEdit();
test.setText("Updating...");

doStuff.runSTLcppRoutine();

To copy to clipboard, switch view to plain text mode 

The call to QLineEdit::setText() does not get updated until doStuff.runSTLCppRoutine() returns despite being physically before it. Can somebody help with this?

Many Thanks.
