Language Selector QCombobox question

[MarkoSan]

Good morning to all, especialy nice and kind experts like wysota and jpn!!!

Can I get some help, please? I need a QComboBox that act as language selector widget. I've written this (header):

#ifndef CLANGUAGESETTINGSPAGE_H_
#define CLANGUAGESETTINGSPAGE_H_
 
// qt includes
#include <QtGui>
#include <QVBoxLayout>
#include <QHBoxLayout>
#include <QPointer>
#include <QString>
 
// custom includes
#include "globals.h"
class CLanguageSettingsPage : public QWidget
{
public:
    CLanguageSettingsPage(QWidget* pParent=0);
    ~CLanguageSettingsPage();
 
    inline QPointer<QLabel> languageSelectorLB()
        { return m_pLangaugeSelectorLB; };
    inline QPointer<QComboBox> languageSelectorCB()
        { return m_pLanguageSelectorCB; };
    inline QPointer<QHBoxLayout> languageSelectorHBL()
        { return m_pLanguageSelectorHBL; };
 
private:
    QPointer<QLabel> m_pLangaugeSelectorLB;    // lang. sel. label
    QPointer<QComboBox> m_pLanguageSelectorCB;    // lang. sel. combo box
    QPointer<QHBoxLayout> m_pLanguageSelectorHBL;    // lang. sel. horiz. layout
};
 
#endif /*CLANGUAGESETTINGSPAGE_H_*/

#ifndef CLANGUAGESETTINGSPAGE_H_
#define CLANGUAGESETTINGSPAGE_H_

// qt includes
#include <QtGui>
#include <QVBoxLayout>
#include <QHBoxLayout>
#include <QPointer>
#include <QString>

// custom includes
#include "globals.h"
class CLanguageSettingsPage : public QWidget
{
public:
    CLanguageSettingsPage(QWidget* pParent=0);
    ~CLanguageSettingsPage();
    
    inline QPointer<QLabel> languageSelectorLB()
        { return m_pLangaugeSelectorLB; };
    inline QPointer<QComboBox> languageSelectorCB()
        { return m_pLanguageSelectorCB; };
    inline QPointer<QHBoxLayout> languageSelectorHBL()
        { return m_pLanguageSelectorHBL; };

private:
    QPointer<QLabel> m_pLangaugeSelectorLB;    // lang. sel. label
    QPointer<QComboBox> m_pLanguageSelectorCB;    // lang. sel. combo box
    QPointer<QHBoxLayout> m_pLanguageSelectorHBL;    // lang. sel. horiz. layout
};

#endif /*CLANGUAGESETTINGSPAGE_H_*/

and it's implementation:

#include "CLanguageSettingsPage.h"
 
CLanguageSettingsPage::CLanguageSettingsPage(QWidget* pParent)
: QWidget(pParent)
{
    // language selector label
    m_pLangaugeSelectorLB=new QLabel(tr("Client default language:"), this);    // creates new label
    Q_CHECK_PTR(m_pLangaugeSelectorLB);    // checks creation
    //m_pLangaugeSelectorLB->setFrameStyle(QFrame::Panel | QFrame::Raised);    // test
    // **** end oflanguage selector label
 
    // language selector combo box
    m_pLanguageSelectorCB=new QComboBox(this);    // creates new combo box
    Q_CHECK_PTR(m_pLanguageSelectorCB);    // checks creation
    m_pLanguageSelectorCB->addItem("SlovenÅ¡čina");
    m_pLanguageSelectorCB->addItem("English");
    m_pLanguageSelectorCB->addItem("Deutsch");
    m_pLanguageSelectorCB->addItem("Italiano");
    m_pLanguageSelectorCB->addItem("Español");
    // **** end oflanguage selector combo box
 
    // layout creation
    m_pLanguageSelectorHBL=new QHBoxLayout();    // creates new layout
    Q_CHECK_PTR(m_pLanguageSelectorHBL);    // checks creation
    // adds widget to layout
    m_pLanguageSelectorHBL->addWidget(m_pLangaugeSelectorLB);
    // adds widget to layout
    m_pLanguageSelectorHBL->addWidget(m_pLanguageSelectorCB);
    // sets layout
    setLayout(m_pLanguageSelectorHBL);
}
 
CLanguageSettingsPage::~CLanguageSettingsPage()
{
}

#include "CLanguageSettingsPage.h"

CLanguageSettingsPage::CLanguageSettingsPage(QWidget* pParent)
: QWidget(pParent)
{
    // language selector label
    m_pLangaugeSelectorLB=new QLabel(tr("Client default language:"), this);    // creates new label
    Q_CHECK_PTR(m_pLangaugeSelectorLB);    // checks creation
    //m_pLangaugeSelectorLB->setFrameStyle(QFrame::Panel | QFrame::Raised);    // test
    // **** end oflanguage selector label

    // language selector combo box
    m_pLanguageSelectorCB=new QComboBox(this);    // creates new combo box
    Q_CHECK_PTR(m_pLanguageSelectorCB);    // checks creation
    m_pLanguageSelectorCB->addItem("SlovenÅ¡čina");
    m_pLanguageSelectorCB->addItem("English");
    m_pLanguageSelectorCB->addItem("Deutsch");
    m_pLanguageSelectorCB->addItem("Italiano");
    m_pLanguageSelectorCB->addItem("Español");
    // **** end oflanguage selector combo box
    
    // layout creation
    m_pLanguageSelectorHBL=new QHBoxLayout();    // creates new layout
    Q_CHECK_PTR(m_pLanguageSelectorHBL);    // checks creation

    m_pLanguageSelectorHBL->addWidget(m_pLangaugeSelectorLB);
    // adds widget to layout
    m_pLanguageSelectorHBL->addWidget(m_pLanguageSelectorCB);
    // sets layout
    setLayout(m_pLanguageSelectorHBL);
}

CLanguageSettingsPage::~CLanguageSettingsPage()

}

Everything works fine, however, language native charaters (in Slovenian language and Espanol) are not shown. How do I achieve so native characters will be shown?? I've attached a sscreenshot of a problem.

[ChristianEhrlicher]

Your compiler treats the source as whatever it likes (either latin1 or utf-8 I guess) but there your native chars are no available / wrong.
Don't use native chars in source code as you can never predict how (== which encoding) a specific compiler interprets the source.

[MarkoSan]

So, there is no solution to this problem? Then I simply must translate all languages into English (which is not a problem, but I would really like to know how to implement more than language support for further use).

[ChristianEhrlicher]

use QTranslator to translate the english names into their native characters

[MarkoSan]

Ok, will do so, but i do not like this solution, but can I use, QTextCodec class, do you have any experience with it?

[ChristianEhrlicher]

QTextCodec can't help you here either - As I said you can't be sure what codec the compiler is using.
But this can work:

QString str = "Sloven" + QChar(0x1234) + QChar(0x1235) + "ina";

QString str = "Sloven" + QChar(0x1234) + QChar(0x1235) + "ina";

To copy to clipboard, switch view to plain text mode 

where 0x1234 and 0x1235 should be the correct unicode numbers for Å¡ and č .
