[Qt-interest] qtoolbar

[Pradeep K Vijayan]

Hi,

The below code worked for me with Qt 4.6.3:

#include <QApplication>
#include <QMainWindow>
#include <QLineEdit>
#include <QToolBar>
#include <QLabel>

class MainWindow : public QMainWindow
{
public:
    MainWindow( QWidget* parent = NULL )
        : QMainWindow( parent )
    {
          m_networkLineEdit = new QLineEdit( this );

          // Set attributes.
          m_networkLineEdit->setReadOnly(true);
          m_networkLineEdit->setMaxLength(17); /* Allow max of 17 
characters. */

          QToolBar* m_networkIdToolBar = addToolBar( "" );
          m_networkIdToolBar->addWidget(new QLabel( "Blah:" ));
          m_networkIdToolBar->addWidget(m_networkLineEdit);
          m_networkIdToolBar->addWidget(new QLabel( "The end!" ));
    }

    void foo()
    {
          m_networkLineEdit->setFixedWidth( 17 * 
m_networkLineEdit->fontMetrics().maxWidth() + 20);
    }

private:
    QLineEdit* m_networkLineEdit;
};

int main( int argc, char* argv[] )
{
    QApplication app( argc, argv );
    MainWindow mw;
    mw.resize( 600, 200 );
    mw.show();
    mw.foo();
    return app.exec();
}
