Adobe have announced the official EOL for flash is 2020 so we're now at the point where support for flash just isn't interesting any more. It doesn't make sense to support it for the upcoming 3.2.x release series, and the sample .swf files are lacking source code. Closes https://github.com/wxWidgets/wxWidgets/pull/1427 Closes #15886.

@class wxActiveXEvent
|
|
|
|
An event class for handling ActiveX events passed from wxActiveXContainer.
|
|
|
|
ActiveX events are basically a function call with the parameters passed
|
|
through an array of wxVariants along with a return value that is a wxVariant
|
|
itself. What type the parameters or return value are depends on the context
|
|
(i.e. what the .idl specifies).
|
|
|
|
@beginEventTable{wxActiveXEvent}
|
|
@event{EVT_ACTIVEX(func)}
|
|
Sent when the ActiveX control hosted by wxActiveXContainer receives an
|
|
ActiveX event.
|
|
@endEventTable
|
|
|
|
ActiveX event parameters can get extremely complex and may be beyond the
|
|
abilities of wxVariant. If 'operator[]' fails, prints an error messages or
|
|
crashes the application, event handlers should use GetNativeParameters()
|
|
instead to obtain the original event information.
|
|
Calls to operator[] and GetNativeParmeters() can be mixed. It is valid
|
|
to handle some parameters of an event with operator[] and others directly
|
|
through GetNativeParameters(). It is \b not valid however to manipulate
|
|
the same parameter using both approaches at the same time.

@class wxActiveXContainer
|
|
|
|
wxActiveXContainer is a host for an ActiveX control on Windows (and as such
|
|
is a platform-specific class).
|
|
|
|
Note that the HWND that the class contains is the actual HWND of the ActiveX
|
|
control so using dynamic events and connecting to @c wxEVT_SIZE, for example,
|
|
will receive the actual size message sent to the control.
|
|
|
|
It is somewhat similar to the ATL class CAxWindow in operation.
|
|
|
|
The size of the ActiveX control's content is generally guaranteed to be that
|
|
of the client size of the parent of this wxActiveXContainer.
|
|
|
|
You can also process ActiveX events through wxActiveXEvent.
|
|
|
|
|
|
@section activexcontainer_example Example
|
|
|
|
This is an example of how to use the Adobe Acrobat Reader ActiveX control to
|
|
read PDF files (requires Acrobat Reader 4 and up).
|
|
Controls like this are typically found and dumped from OLEVIEW.exe that is
|
|
distributed with Microsoft Visual C++.
|
|
This example also demonstrates how to create a backend for wxMediaCtrl.
