Re: cannot allocate an object of abstract type
Hi,
As WebCore::ChromeClient contains pure virtual function, it must override all the pure virtual functions.
You can provide default definition as of now for compilation as provided for other functions:
For example:
bool ChromeClient::hasOpenedPopup() const
{
notImplemented();
return false;
}
I believe that it will resolve the compilation error.
Thanks,
Prince Goyal
