I just checked in new codes of PPCam to SVN on sourceforge.net, I guess I won’t spend too much time on visual effect in the future, so what we have now is most likely what we have all the time:

  • no Windows gadget, i.e. no toolbox, no menu, no border, no title bar
  • semi-transparent effect, means you can still read content on windows below PPCam
  • Moving by any point, means you can click on any position of the window and drag & drop the window to the new place, this is a must as it does not have title bar for this

Note that this is data driven 😉 , I learnt the idea from previous music player project – you can just provide a bmp file, and the application will take top-left point as “transparent sample”, then any points in the bmp that has the same color as top-left point will be treated as transparent. This feature makes really easier to change the look and feel.

Other than these visible changes, that are some codes related changes, may or may not be that interesting:

  • Added win32api.ads to include those Win32 APIs that the project needs to use, but are missing in win32ada binding
  • PPCam now becomes a dummy top level package, it used to have those data conversion functions but obviously I can use those from win32ada
  • Added a bmp to the source, this is the bmp I used to debug/demo
  • I’m trying to turn some functions to procedures whenever I don’t need a return code, I think this is another C habit needs to be changed

There will be couple of parts of features to be done in the coming days

  1. Include vfw features, I haven’t got any idea so far
  2. Pop-up menus for the interface to let user enter user name/password/server name, etc
  3. Network, UDP only, then later on I need to have P2P based on it
  4. Server, another GNAT Ada program that will be running on a server to handle authentication, port discovery, etc

I believe this project will be running pretty long thinking of how much I have to learn, if I can make a workable version by June I will be super happy.

I will try to check in at least every week so to make the project active, I will also post documents (svn first, web site later) so to make it possible for others to understand the whole project well.

  One Response to “Checked in new codes”

  1. I think … I should rename those identifiers with Ada style, while leaving those Windows definitions still in Windows style.

    Current codes look a little bit weird, Ada program with lots of C/C++ styles around …
