Problems using generator
Message 1 in thread
Hello!
I'm getting some strange error messages when I try to compile a C++ Qt
widget using the jambi generator.
../cpp/com_poseidon_mapborealis/qtjambishell_CMbSimpleTextItem.cpp: In
function 'void
Java_com_poseidon_mapborealis_CMbSimpleTextItem__1_1qt_1setText_1String__JLjava_lang_String_2(JNIEnv*,
_jclass*, jlong, _jobject*)':
../cpp/com_poseidon_mapborealis/qtjambishell_CMbSimpleTextItem.cpp:1290:
error: invalid conversion from '_jobject*' to 'jlong'
../cpp/com_poseidon_mapborealis/qtjambishell_CMbSimpleTextItem.cpp:1290:
error: initializing argument 1 of 'void* qtjambi_from_jlong(jlong)'
The class definition looks like this:
class CMbSimpleTextItem : public CMbItem
{
public:
void setText( const QString text );
QString text() const { return _text; };
private:
QString _text;
QGraphicsSimpleTextItem *_textItem;
void init();
public:
CMbSimpleTextItem ( QString text, CMbItem * parent = 0, CMbScene*
scene = 0 );
CMbSimpleTextItem ( CMbItem *parent = 0, CMbScene* scene = 0 );
~CMbSimpleTextItem();
virtual QRectF boundingRect() const;
virtual void paint(QPainter *painter, const QStyleOptionGraphicsItem
*option, QWidget *widget);
};
where CMbItem looks like this:
class CMbItem : public QGraphicsItem
{
public:
enum CMbItemType
{
General = UserType + 1,
Point,
Ship,
Anchor,
Fairlead,
Bollard,
MooringCable
};
private:
void init();
CIdFactory *_idFactory;
unsigned int _id;
public:
CMbItem ( QGraphicsItem * parent = 0, CMbScene* scene = 0 );
CMbItem ( QPointF pos, QGraphicsItem *parent = 0, CMbScene* scene =
0 );
~CMbItem();
virtual QRectF boundingRect() const;
virtual void paint(QPainter *painter, const QStyleOptionGraphicsItem
*option, QWidget *widget);
void setPos( const QPointF& pos );
void removeChildren();
unsigned int id() const { return _id; };
virtual int type () const;
protected:
virtual void mousePressEvent( QGraphicsSceneMouseEvent *event );
virtual void hoverEnterEvent( QGraphicsSceneHoverEvent *event );
virtual void hoverLeaveEvent( QGraphicsSceneHoverEvent *event );
};

Hi Helge,
This is a bug in the generator when you pass strings as const QString
(not reference). If you change your signature to be:
const QString &
you'll not run into this problem, which is probably what you intended in
the first place ;-)
I've attached a patch to the generator which solves the problem there too.
best regards,
Gunnar
