[Marble-devel] Question

[Bryan Greenway]

Hello,

 

I am trying to put the MarbleWidget into a Qt only application using Qt
Creator, and am having some difficulty.  Here's is what I've done thus far:

 

1.       Followed instructions for downloading and compiling Marble on
Windows.  That seemed to go fine.

 

2.       I looked at the QtMainWindow.cpp as a model for what I was putting
together.  I deviated from that approach somewhat as I am creating a simple
Dialog app.  On this dialog, I am trying  to instantiate a ControlView (as
is done in QtMainWindow) from ControlView.cpp/.h.  See dialog.cpp/.h below.

 

 

////////////////////////////////

#ifndef DIALOG_H

#define DIALOG_H

#include <QDialog>

#include "ControlView.h"

namespace Ui {

    class Dialog;

}

namespace Marble{

class MarbleWidget;

class Dialog : public QDialog

{

    Q_OBJECT

public:

    explicit Dialog(const QString& marbleDataPath,QWidget *parent = 0);

    ~Dialog();

    ControlView* marbleControl(){return m_controlView;}

    MarbleWidget* marbleWidget(){return m_controlView->marbleWidget();}

private:

    Ui::Dialog *ui;

    ControlView *m_controlView;

private slots:

    void on_QuitPB_clicked();

};

} // namespace Marble

#endif // DIALOG_H

 

////////////////////////////////

#include "dialog.h"
#include "ui_dialog.h"
using namespace Marble;
Dialog::Dialog(const QString& marbleDataPath,QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);
    m_controlView = new ControlView(this);
    setWindowTitle("MIT Lincoln Lab - COTM Tracker");
}
Dialog::~Dialog()
{
    delete ui;
}
void Dialog::on_QuitPB_clicked()
{
    exit(0);
}

 

 

////////////////////////////////

#include <QtGui/QApplication>

using namespace Marble;

int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    QString marbleDataPath = "C:\\Program Files\\Marble 0.8.0\\data";

    Dialog *mp_dialog = new Dialog(marbleDataPath);

    mp_dialog->setAttribute(Qt::WA_DeleteOnClose,true);

    mp_dialog->show();

    return a.exec();

}

My observations:

 

It appears to me that I'm not getting my libmarblewidget library to link.
The file: libmarblewidget.dll is definitely in the c:\marble-build\src\lib\"
directory.  And the makefile has the line:

LIBS        =        -L"c:\Qt\2010.04\qt\lib" -lmingw32 -lqtmain
"-Lc:\marble-build\src\lib -lmarblewidget.dll" -lQtGui4 -lQtCore4

 

It also appears to me that I need to link in something for the
MarbleControlBox and MapThemeManager.  I'm guessing that these are not part
of the MarbleWidget, so something else will need to be included.

 

 

Any help/suggestions would be greatly appreciated.  I apologize for the long
email.

 

Thanks very much!!

 

Bryan
