Topic for Delphi plugin developers

[DrLobo]

Hi,

the aim of this topic is to gather knowledge about plugin development with Delphi.

You can find some code by browsing this forum, but I never found a complete example on how a delphi plugin should be.

Here some code that could be useful to start:

tutorial for a general plugin:
www.sntd.de
This is one is old (2000!) and based on winamp 2.x api but works.

One of the most intersting thing, was the translation of winamp 2.9.x api by Saivert:

I have ported (or, actually translated) the C/C++ code and headers from the WA 2.9x SDK to Object Pascal (for use with Borland Delphi).

A little about the so-called skin SDK:
What you actually get when you download the above Winamp 2.9x SDK is two headers.
One called wa_ipc.c (wa_ipc.pas in my ZIP).
And one called wa_dlg.h (wa_dlg.pas in my ZIP). So to make your plugin window look like the rest of Winamp's window you must implement a lot of the code that is in wa_dlg.h. When you write your Window Procedure you must pass the hwnd, msg, wParam and lParam to a function called "WADlg_handleDialogMsgs". Like this:

function LRESULT myWndProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {
int a=WADlg_handleDialogMsgs(hwnd, uMsg, wParam, lParam); if a > 0 return a;
switch uMsg
{
case WM_DISPLAYCHANGE:
WADlg_init(hwnd);
// Do other stuff here
}
}

but I never found how to use it...


If somebody could create a very simple general plugin with the new api (and with skinned,dockable windows), I think it will help a lot of people (and me the first!).
