一个关于ActiveX的问题

[gxg...@gmail.com]

一，二，三是背景介绍，四，五是需求。

一，用QAxBase::generateDocumentation()功能生成了ActiveX控件的reference，片段如下：

============================================================================

[b][u]Signals:[/u][/b]

void DisplayExecution(IDispatch* exec, ExecutionDisplayReasons reason);

void ExitApplication();

void DisplaySequenceFile(IDispatch* file, SequenceFileDisplayReasons reason);

void ExitApplication () [signal]

Connect a slot to this signal:

QObject::connect(object, SIGNAL(ExitApplication()), receiver, SLOT(someSlot()));

void DisplayExecution (IDispatch* exec, ExecutionDisplayReasons reason) [signal]

Connect a slot to this signal:

QObject::connect(object, SIGNAL(DisplayExecution(IDispatch*, ExecutionDisplayReasons)), receiver, SLOT(someSlot(IDispatch*, ExecutionDisplayReasons)));

void DisplaySequenceFile (IDispatch* file, SequenceFileDisplayReasons reason) [signal]

Connect a slot to this signal:

QObject::connect(object, SIGNAL(DisplaySequenceFile(IDispatch*, SequenceFileDisplayReasons)), receiver, SLOT(someSlot(IDispatch*, SequenceFileDisplayReasons)));

============================================================================

二，在这个ActiveX控件中原生的说明文档中，对应的片段如下：

[u][b]Events[/b][/u]

DisplaySequenceFile Event

Syntax

ControlName_DisplaySequenceFile ( file, reason)

DisplayExecution Event

Syntax

ControlName_DisplayExecution ( exec, reason)

============================================================================

三，在MFC中对应的代码如下：

BEGIN_EVENTSINK_MAP(CTestExecDlg, CDialog)

    //{{AFX_EVENTSINK_MAP(CTestExecDlg)

ON_EVENT(CTestExecDlg, IDC_APPLICATIONMGR, 1 /* ExitApplication */, OnExitApplication_ApplicationMgr, VTS_NONE)

ON_EVENT(CTestExecDlg, IDC_APPLICATIONMGR, 10 /* Wait */, OnWait_ApplicationMgr, VTS_BOOL)

ON_EVENT(CTestExecDlg, IDC_APPLICATIONMGR, 11 /* HandleError */, OnHandleError_ApplicationMgr, VTS_I4 VTS_BSTR)

ON_EVENT(CTestExecDlg, IDC_APPLICATIONMGR, 22 /* DisplayExecution */, OnDisplayExecutionApplicationMgr, VTS_DISPATCH VTS_I4)

ON_EVENT(CTestExecDlg, IDC_APPLICATIONMGR, 21 /* DisplaySequenceFile */, OnDisplaySequenceFileApplicationMgr, VTS_DISPATCH VTS_I4)

//}}AFX_EVENTSINK_MAP

END_EVENTSINK_MAP()

============================================================================

四，目前的需求是，在pyqt中实现类似MFC这段代码的功能，按ActiveX控件供应商的话来说就是create ActiveX event handlers就可以了。不知道在pyqt中如何进行create ActiveX event handlers。根据第一段生成的reference，似乎是可以用pyqt的signal/slot的机制来create ActiveX event handlers（对应mfc的eventsink map那段的代码），但是不知道代码要如何写：

QObject::connect(object, SIGNAL(DisplayExecution(IDispatch*, ExecutionDisplayReasons)), receiver, SLOT(someSlot(IDispatch*, ExecutionDisplayReasons)))

五，等效的需求。在http://blog.csdn.net/yangxiao_0203/article/details/7422715这篇文章中，有人用excel的ActiveX控件也搞了一个reference，如果有基于excel的create ActiveX event handlers的代码可以参考一下也可以。另外我还没搞明白系统中哪个ActiveX控件是对应excel的，从而可以通过generateDocumentation()获取excel的reference。

多谢大家啦。
