Detailed Description

QAxSelect dialog can be used to provide users with a way to browse the registered COM components of the system and select one. It also provides a combo box for selecting desired sandboxing level. The CLSID of the selected component can then be used in the application to e.g. initialize a QAxWidget:

QAxSelect select;
if (select.exec()) {
    QAxWidget *container = new QAxWidget;

Member Type Documentation

enum QAxSelect::SandboxingLevel

The SandboxingLevel enumeration defines the desired level of ActiveX sandboxing.

QAxSelect::SandboxingNone0No specific sandboxing desired
QAxSelect::SandboxingProcess1Run ActiveX control in a separate process
QAxSelect::SandboxingLowIntegrity2Run ActiveX control in a separate low-integrity process
QAxSelect::SandboxingAppContainer3[since 6.5] Run ActiveX control in a separate AppContainer-isolated process

Sandboxing requires that the ActiveX is either built as an EXE, or as a DLL with AppID "DllSurrogate" enabled.
