[SOLVED] How to find out about "read only properties"

I try to populate a QObject descendant with the properties of another QObject descendant to have them identical (for example set a QTreeView to have the same property values as another QTreeView). Retrieving all properties poses no problems:

Code:

---

QStringList properties;
 
for(int i = 0; i < myTreeView->propertyCount(); ++i)
    properties << QString::fromLatin1(myTreeView->property(i).name());

---

When applying the properties to another object I do verify that a property exists like this:

Code:

---

const  QMetaObject* moOtherTreeView = otherTreeView->metaObject();
 
...
 
QByteArray propName = properties[ix].toLatin1();
 
// Make sure prop exists
 
if (moOtherTreeView->indexOfProperty(propName) < 0)
    continue;    // ignore this property
 
...
 
// Ok, apply property
 
otherTreeView->setProperty(propName, myTreeView->property(propName));

---

But unfortunately some of the properties are read only, which is reported by Qt in the debug output:

Code:

---

...
 
updatesEnabled
visible
minimized
QTreeView::setProperty: Property "minimized" invalid, read-only or does not exist
maximized
QTreeView::setProperty: Property "maximized" invalid, read-only or does not exist
fullScreen
QTreeView::setProperty: Property "fullScreen" invalid, read-only or does not exist
sizeHint
 
...

---

My question now is how to find out whether a property is read only or not?

thanks for any reply!

Try checkout return value
bool QObject::setProperty ( const char * name, const QVariant & value )

or

Code:

---

QMetaProperty QMetaObject::property ( int index ) const
bool QMetaProperty::isWritable () const

---

Thank you, SABROG

The isWritable() method perfectly solves my problem (next time I should have a deeper look at the Qt docs).
