[news.eclipse.platform.swt] WMPlayer.OCX (Windows Media Player) trouble

[Philip Mayer <news@xxxxxxxxxx>]

Hello everyone,

This has been in this group before, but I didn't really find a solution 
for it. The problem is as follows:

I am trying to use the Windows Media Player (v.10), WMPlayer.OCX, to 
display video inside an SWT frame. I have sucessfully activated the 
control and played back some video (Eclipse3.1RC1).

The control, however, cannot be activated using 
OLE.OLEIVERB_INPLACEACTIVATE (results in a VM crash; there is a bug 
report on this), but only using OLE.OLEIVERB_SHOW. I SUSPECT that all 
the following problems are because of this (correct?).

So, when using OLEIVERB_SHOW, it is VERY difficult to set the sizes of 
the OleFrame and the OleControlSite to the right values in order to 
display the whole video picture (and only the picture) inside the frame. 
There are really weird things going on there; mostly, the video is 
displayed only partly and in strange places inside the black media 
player area (right click to invoke the media player context menu is 
possible everwhere). I have found the size (300/206) to be working for 
me - but only this size, which really is not a solution.

If I use FillLayout or any other layout which allows me to resize the 
control, the video gets only partly displayed. I tried setting the 
control's size via listeners, but this doesn't work.

Attached is some code which shows how the WMPlayer tries to play back 
the video somewhere inside the frame.

Any ideas? :) Thanks !! :)
