// Generally, the objects they point to are deleted only after kpView

|

//
|
|
// However, sometimes we use deleteLater() for the kpView.
|
|
// Before the delayed deletion is executed, those objects are deleted
|
|
// and then our paintEvent() is called. paintEvent() must therefore
|
|
// have some way of realising that those objects have been deleted so
|
|
// we use guarded pointers.
