This class makes it possible to have nested scoped calls to QWidget::setUpdatesEnabled.
|
|
|
|
For that matter:
|
|
|
|
@code
|
|
{
|
|
...
|
|
setUpdatesEnabled(false);
|
|
someCall();
|
|
setUpdatesEnabled(true);
|
|
...
|
|
}
|
|
@endcode
|
|
|
|
Would be equivalent to
|
|
|
|
@code
|
|
{
|
|
...
|
|
HoldUpdates hu(this);
|
|
someCall();
|
|
hu.stop();//if we need to, otherwise we can let it fall out of scope
|
|
...
|
|
}
|
|
@endcode
|
|
|
|
if someCall was using HoldUpdates too, it will make sure to only call setUpdatesEnabled(true) in case it's needed.
