In your question whereas there is a class named window and it would be like this:
class window {
//code here
}
Next is there is a function called close and freeresource and it goes like this:
class window{
function close( ){
//code here
}
function freeresource( ){
// code here
}
public destruct (){
this.close();
this.freeresource();
}
}
The last code function destruct invokes the function close and freeresource. Hope this would help
