Tracking memory consumption of plugins.

[wysota]

You can have a stack variable with a small memory footprint that will simply be initialized in the init, like so:

class .. {
 
private:
  QImage img;
...};
void ...::init(){
  img = QImage(800,600,...);
}

class .. {

private:
  QImage img;
...};
void ...::init(){
  img = QImage(800,600,...);
}

To copy to clipboard, switch view to plain text mode 

img is allocated on stack but initialized (and expanded) in init().

BTW. In the interface those methods have to be virtual.
