我想问下，有没有讲解Qt开发ActiveX控件的（就是微软的COM组件），用于网页调用的。下面的我不理解，我从没接触过 ActiveQt framework，哪位能给点指点，非常感谢！！
The QAxServer module is part of the ActiveQt framework. It consists of three classes:
QAxFactory defines a factory for the creation of COM objects.
QAxBindable provides an interface between the Qt widget and the COM object.
QAxAggregated can be subclassed to implement additional COM interfaces.
Some example implementations of ActiveX controls and COM objects are provided.
Topics:
Using the Library
To turn a standard Qt application into a COM server using the QAxServer library you must add axserver to the QT variable in your .pro file.
An out-of-process executable server is generated from a .pro file like this:
TEMPLATE = app
QT += axserver
RC_FILE = qaxserver.rc
...
To build an in-process server, use a .pro file like this:
TEMPLATE = lib
QT += axserver
CONFIG += dll
DEF_FILE = qaxserver.def
RC_FILE = qaxserver.rc
...
The files qaxserver.rc and qaxserver.def are part of the framework and can be used from their usual location (specify a path in the .pro file), or copied into the project directory. You can modify these files as long as it includes any file as the type library entry, ie. you can add version information or specify a different toolbox icon.
Using the axserver module will cause the qmake tool to add the required build steps to the build system:
Link the binary against qaxserver.lib instead of qtmain.lib
Call the idc tool to generate an IDL file for the COM server
Compile the IDL into a type library using the MIDL tool (part of the compiler installation)
Attach the resulting type library as a binary resource to the server binary (again using the idc tool)
Register the server
To skip the post-processing step, also set the qaxserver_no_postlink configuration.
Additionally you can specify a version number using the VERSION variable, e.g.
TEMPLATE = lib
VERSION = 2.5
...
The version number specified will be used as the version of the type library and of the server when registering. |
