Qt Integration

I took a break from the video player I was trying to create with a frame-by-frame step feature. But I am back on that now and I have found a player that contains the frame-by-frame skipping. It is the playwnd program provided by Microsoft's DirectShow samples. What I would like to add to this sample are some buttons below the video player that would allow for the frame skipping, and possible a play/pause button and a stop button. These are already implemented through a menu system and keyboard shortcuts, but the buttons are a requirement. Is there anyway to use Qt to add these buttons to this already existing program? I know how to create buttons in the .ui file and I have experimented with them a little bit. But I do not know how I can add these to the already exisiting player. I am guessing that since this is a Microsoft sample, the code is implemented using MFC. I could be wrong, but this is just an assumption. Thank you for all your help and continued support to us Qt users!

You can mix MFC and Qt, however this is neither nice nor portable. There are tools from Trolltech for migrating MFC-Apps with Qt but I think you'll have to buy them. You can get a handle for a QWidget using http://doc.trolltech.com/4.1/qwidget.html#winId and set up your directx context there. So the solution is to make a Qt-App and let directx render into a QWidget.

I have read through the documentation for QWidget, but I am confused as to how I can stick in DirectX code into the widget and get it to display my video. I have a GUI all built and have a QFrame set aside to put the video into, but I am confused with the integration. Maybe I am not understanding the documentation correctly. If you have some ideas as to where I could look for some examples or more help, that would be great. Thanks!

I know my DirectShow object is a COM object and I think I know how to integrate this into my Qt project. My problem is trying to find the ID number to create a DirectShow object in a QWidget or perhaps a QAxWidget. Does anybody have this ID for a DirectShow object so I can access the object through Qt? I have seen numerous CLSIDs for DirectShow, but have no idea which one if any may be correct. Thanks again!

It should be in the documentation of the COM server (msdn.com probably)
