promoted widget constructor not called

[Seb Tur]

Hi
I have a customized QTableView class with constructor as below

iTableView::iTableView(QWidget *parent):
QTableView(parent)
{
qDebug()<<Q_FUNC_INFO;
}

in QtDesigner I promoted a QTableView widget in my mainwindow ui to iTableView

when I run program the constructor does not get called / no debug is visible

I check ui_mainwindow.h and I can see
rw = new QWidget();
TV_rw = new iTableView(rw);

@Seb-Tur said in promoted widget constructor not called:

TV_rw = new iTableView(rw);

If this line is executed then iTableView::iTableView(QWidget *parent) will be called (assuming your class declaration in .h is correct and constructor shown is indeed read in) . Put a breakpoint on the calling line to see if it is hit?

There is nothing special about designer code or promotion. You can see the .h files generated so then it is just C++ code. You will have to diagnose this yourself: do a clean rebuild, make sure the .cpp/.h/ui_....h files are all in the right place and it's not picking up an old one, etc.

@JonB
It was probably due to some kind of glitch that in global "promotions" dialog I had a customwidget with invalid header file specified to completely different class. It might have happended when I renamed my class files and I expect this is when it happened.

Now all works I expected, thanks for trying to help and assuring me that it was nothing wrong in the code.

@Seb-Tur When you get "unexpected" behaviour in Qt program, first thing to try is a clean, complete rebuild because of stuff like this!
