Hi there,

I'm just following examples from Jasmin Blanchette's book "C++ GUI Programming with Qt 4" Second Edition, which seems to be very good so far. The only area I'm having any difficulty with is using Qt Designer to generate C++ header files.

In the gotocelldialog example, from Chapter 2, when I run qmake -project & qmake gotocell.pro the ui_gotocelldialog.h file is not created. I've searched on my system and it didn't appear in any other path either.

I am running the latest 2010.05 realease of the Qt SDK on Windows XP SP3 under the LGPL license (although my license knowledge is somewhat limited)

I think my main.cpp file is the same as the example

Qt Code: 
  1. #include <QApplication>
  2. #include <QDialog>
  3. #include "ui_gotocelldialog.h"
  4. int main(int argc, char *argv[])
  5. {
  6. 	QApplication app(argc, argv);
  7.  
  8. 	Ui::GoToCellDialog ui;
  9. 	QDialog *dialog = new QDialog;
  10. 	ui.setupUi(dialog);
  11. 	dialog->show();
  12.  
  13. 	return app.exec();
  14. }

The example files show a ui file as follows:

Qt Code: 
  1. <ui version="4.0" >
  2.  <class>GoToCellDialog</class>
  3.  <widget class="QWidget" name="GoToCellDialog" >

There seems to be something going on with

Qt Code: 
  1. 1.<?xml version="1.0" encoding="UTF-8"?>
To copy to clipboard, switch view to plain text mode 

Any ideas why Qt Designer is generating this difference, or if it is an issue?
