Print out graphics item type information

[sajis997]

Hello forum,

I am having issues while printing out the graphics item type information. I want to print the verbose information not the numeric one.

Is there any mechanism in Qt to print the graphics item type, something like the following:

qDebug () << "Item type: " << item->type() << endl;

qDebug () << "Item type: " << item->type() << endl;

To copy to clipboard, switch view to plain text mode 

The above code gives me the numeric value, i would like to have something verbose

You can use the typeid operator to print the class name of any object:

#include <QApplication>
#include <QtCore>
#include <QDebug>
#include <QtGui>
#include <typeinfo>
 
class MyClass
{
};
 
int main(int argc, char **argv) {
 
    QGraphicsLineItem line;
    QGraphicsRectItem rect;
    QApplication app(argc,argv);
    MyClass m;
 
    qDebug() << typeid(line).name() << typeid(rect).name();
    qDebug() << typeid(app).name() << typeid(m).name();
 
    return 0;
}

#include <QApplication>
#include <QtCore>
#include <QDebug>
#include <QtGui>
#include <typeinfo>
 
class MyClass
{
};
 
int main(int argc, char **argv) {
    
    QGraphicsLineItem line;
    QGraphicsRectItem rect;
    QApplication app(argc,argv);
    MyClass m;
    
    qDebug() << typeid(line).name() << typeid(rect).name();
    qDebug() << typeid(app).name() << typeid(m).name();
    
    return 0;
}

To copy to clipboard, switch view to plain text mode 

remember to #include <typeinfo>. The output depends on the compiler, so use this carefully (don't make any assumptions about this value, just use it for your information only):

17QGraphicsLineItem 17QGraphicsRectItem
12QApplication 7MyClass
