[Insight-users] using reader as global variable

[john smith]

Hello to all,

I am using a function in which I am loading a 3D image volume using a
reader,as it seems bellow:

void MainWindow::push_button_File()
{
      ReaderType::Pointer reader = ReaderType::New();
{

how could use this reader as a global variable in order to use the same 3D
volume in an other function?
