Signals
void	accept ()

void	reject ()

Signals inherited from QObject
void	destroyed (QObject *=nullptr)
	This signal is emitted immediately before the object obj is destroyed, after any instances of QPointer have been notified, and cannot be blocked.

void	objectNameChanged (const QString &objectName, QPrivateSignal)
	This signal is emitted after the object's name has been changed.

◆ StyleHint

enum QPlatformDialogHelper::StyleHint

This enum type specifies platform-specific style hints.

\value DialogIsQtWindow Indicates that a platform-specific dialog is implemented as in-process Qt window. It allows to prevent blocking the dialog by an invisible proxy Qt dialog.
