    Default Generating header files from ui files with uic

    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. }
    To copy to clipboard, switch view to plain text mode 

    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" >
    4. <property name="geometry" >

    6. <x>0</x>

    To copy to clipboard, switch view to plain text mode 

    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?

    Default Re: Generating header files from ui files with uic

    Ahhh I see. Sorry for the newbie comment. The header file is generated after running make. This certainly isn't clear in the book though.

    Anyway at least it got me to post something. Hopefully my next post will be more worthwhile.

    Default Re: Generating header files from ui files with uic

    And there are errors with that include when you run nmake, or mingw32-make if you use the SDK, which comes with mingw compiler?
