Check QVariant type

luca

Hi all,
I initialize a QVariant this way:
@
float my_float;
my_float = 12.2;
QVariant my_variant;
...
...
my_variant = QVariant(my_float);
...
...
@

now I need to be sure it's a float and not a double or an int.
QVariant::Type doesn't have "float" but I actually check the type this way:
@
if(my_variant.type() == QMetaType::Float)
{

}
@
this seems to works but I get a warning while compiling:
@
warning: comparison between 'enum QVariant::Type' and 'enum QMetaType::Type'
@

Is this the right way to check the QVariant type?

After reading the sources:
@
QVariant(float f) { d.is_null = false; d.type = QMetaType::Float; d.data.f = f; }

Yes it is! Although you could use int QVariant::userType() if you feel more comfortable comparing to an int.

Note that in Qt 5, the distinction between QVariant::Type and QMetaType::Type will most likely go away.

That's a good news...
