This is prelimanary stuff - the controls need extra methods and events etc,
|
||
|
|
feel free to email with suggestions &/or patches.
|
||
|
|
|
||
|
|
Tested with wxWindows 2.3.2.
|
||
|
|
Built with MS Visual C++ 6.0 & DevStudio
|
||
|
|
Minor use of templates and STL
|

This sample illustrates using wxActiveX and wxIEHtmlWin too:
|
||
|
|
1. Host an arbitrary ActiveX control
|
||
|
|
2. Specifically host the MSHTML Control
|
||
|
|
|
||
|
|
|
||
|
|
wxActiveX:
|
||
|
|
==========
|
||
|
|
wxActiveX is used to host and siplay any activeX control, all the wxWindows developer
|
||
|
|
needs to know is either the ProgID or CLSID of the control in question.
|
||
|
|
|
||
|
|
Derived From:
|
||
|
|
- wxWindow
|
||
|
|
|
||
|
|
Include Files:
|
||
|
|
- wxactivex.h

|
wxActiveX::wxActiveX(wxWindow * parent, REFCLSID clsid, wxWindowID id = -1);
|
||
|
|
- Creates a activeX control identified by clsid
|
||
|
|
e.g
|
||
|
|
wxFrame *frame = new wxFrame(this, -1, "test");
|
||
|
|
wxActiveX *X = new wxActiveX(frame, CLSID_WebBrowser);
|
||
|
|
|
||
|
|
wxActiveX::wxActiveX(wxWindow * parent, wxString progId, wxWindowID id = -1);
|
||
|
|
- Creates a activeX control identified by progId
|
||
|
|
e.g.
|
||
|
|
wxFrame *frame = new wxFrame(this, -1, "test");
|
||
|
|
wxActiveX *X = new wxActiveX(frame, "MSCAL.Calendar");
|
||
|
|
|
||
|
|
|
||
|
|
wxActiveX::~wxActiveX();
|
||
|
|
- Destroys the control
|
||
|
|
- disconnects all connection points
|
||
|
|
|
||
|
|
HRESULT wxActiveX::ConnectAdvise(REFIID riid, IUnknown *eventSink);
|
||
|
|
- Connects a event sink. Connections are automaticlly diconnected in the destructor
|
||
|
|
e.g.
|
||
|
|
FS_DWebBrowserEvents2 *events = new FS_DWebBrowserEvents2(iecontrol);
|
||
|
|
hret = iecontrol->ConnectAdvise(DIID_DWebBrowserEvents2, events);
|
||
|
|
if (! SUCCEEDED(hret))
|
||
|
|
delete events;

wxIEHtmlWin::wxIEHtmlWin(wxWindow * parent, wxWindowID id = -1);
|
||
|
|
- Constructs and initialises the MSHTML control
|
||
|
|
- LoadUrl("about:blank") is called
|
||
|
|
|
||
|
|
wxIEHtmlWin::~wxIEHtmlWin();
|
||
|
|
- destroys the control
|
||
|
|
|
||
|
|
void wxIEHtmlWin::LoadUrl(const wxString&);
|
||
|
|
- Attempts to browse to the url, the control uses its internal (MS)
|
||
|
|
network streams
|
||
|
|
|
||
|
|
bool wxIEHtmlWin::LoadString(wxString html);
|
||
|
|
- Load the passed HTML string
|
||
|
|
|
||
|
|
bool wxIEHtmlWin::LoadStream(istream *strm);
|
||
|
|
- load the passed HTML stream. The control takes ownership of
|
||
|

the pointer, deleting when finished.
|

|
|
void wxIEHtmlWin::SetEditMode(bool seton);
|

|
||
|
|
NOTE: This does work, but is bare bones - we need more events exposed before
|
||
|
|
this is usable as an HTML editor.
|
||
|
|
|
||
|
|
bool wxIEHtmlWin::GetEditMode();
|
