#include <QString> error

[jpn]

It should be:

QT = core sql gui

or simply

QT += sql

(core and gui modules are enabled by default).

Thanks jpn,
That fixed the problem I started with, now I'm left with the other problem I just posted.

I suppose you should add areacodescombobox.h and areacodescombobox.cpp to clientNotebook.pro.

I suppose you should add areacodescombobox.h and areacodescombobox.cpp to clientNotebook.pro.

It is already. Look at posted code above.

It is already. Look at posted code above.

Oh, I thought you said it was a plugin.. Anyway, did you actually implement a function body for AreacodesCombobox constructor?

[vieraci]

Yes the notebook part IS a plugin, and no, I didn't provide a constructor. I thought a default constructor might be provided by Qt... I just implemented the extra functions I need for the comboBox.

The .h file is in this post, this is the cpp file:

void AreacodesCombobox::initializeFields()
{
   QString blank = " ";
   setSelectedAreacode(blank);
   setSelectedLocale(blank);
   clear();
}
 
void AreacodesCombobox::on_returnPressed()
{
   QString aLocale=currentText();
   if ((aLocale.trimmed().length() > 1) && (aLocale != QString(selectedLocale()).toUpper()))
   {
      QString searchText= ("UCASE(locale) like '%");
      searchText.append(aLocale.trimmed().toUpper());
      searchText.append("%' order by LOCALE");
      QString clause = searchWordsClause(aLocale, "locale", "AND", false,"locale");
      clause.prepend("SELECT  Areacode, Locale FROM AreacodesView WHERE ");
      clause.append(" Order by Locale");
      QSqlQuery query(clause);
      if (query.isActive())  // successful execution
      {
         if (query.size()==0)
         {
            QApplication::beep ();
            QMessageBox::warning(this, tr("Postcode Search"),
               tr("No match found.\nCheck the spelling and try again."), QMessageBox::Ok);
            setFocus();
         }
         else
         {
            clear();
            while (query.next()) 
            {
               QString locale = query.value(0).toString();
               addItem(locale);
            }

               QComboBox::setCurrentIndex(1);
            else

Yes the notebook part IS a plugin

But template is "app" and it has main()..?

and no, I didn't provide a constructor. I thought a default constructor might be provided by Qt... I just implemented the extra functions I need for the comboBox.

C++ compilers provide a default constructor in case you don't provide one. But in case you declare anything, you must also implement it:

AreacodesCombobox::AreacodesCombobox(QWidget *parent) : QComboBox(parent)
{
    // ...
}

AreacodesCombobox::AreacodesCombobox(QWidget *parent) : QComboBox(parent)
{
    // ...
}

The .h file is in this post, this is the cpp file:

In case that's really the full .cpp, looks like you're missing implementations of a bunch of other functions as well; setSelectedLocale(), setSelectedAreacode(), selectedLocale(), selectedAreacode().

[vieraci]

But template is "app" and it has main()..?

I created it by followed the example in the docs, now I can't find it, but from memory there was a "main" and template was "app"...but that probably doesn't mean it's correct.

C++ compilers provide a default constructor in case you don't provide one. But in case you declare anything, you must also implement it:

AreacodesCombobox::AreacodesCombobox(QWidget *parent) : QComboBox(parent)
{
    // ...
}

AreacodesCombobox::AreacodesCombobox(QWidget *parent) : QComboBox(parent)
{
    // ...
}

But do I really need a constructor here ? there's nothing special I need to implement there, I'm just adding custom code.

In case that's really the full .cpp, looks like you're missing implementations of a bunch of other functions as well; setSelectedLocale(), setSelectedAreacode(), selectedLocale(), selectedAreacode().

Yes, they're implemented, seems I didn't select the whole file when I copied.
I actually was going to implement a constructor but thought about what I needed to do that was different, answer was "nothing" so I rem-ed it out.

#include "./areacodescombobox.h"

  {
    vSelectedLocale = aSelectedLocale;

So changing TEMPLATE = lib compiles ok, but a simmilar error message appears when I move into the plugin dir and attempt to make the plugin.
