Qt Linguist: translation of text changed dynamically in tr()

Question

I am using qt linguist and qt 5.2. I have a problem that when I add something to .ui files I can see it after lupdate in ts file but when I change name of this button dynamically in my code like:

ui->label->setText(tr("foo"));

I can't see it in ts file, is it possible to make translation in that case? How I can do this?

Answer 1

Basically, tr() can be detected anywhere in the codes.For ui files, linguist would detect the changes immediately, however in codes I encounterd the same problem. Based on my experience, try to reBuilt/qmake it.

(I am using Qt4.8 & 5.1.)
