Win32 bindings

Posted: 01/26/08 07:43:22 While working on DWT-Windows, i encountered problems with the tango.sys.win32 package. I have no expirience with win32 developemnt so i might miss something essential :) 1.) There is this Ansi vs. Unicode thing in windows. Many structs are dependending on the decisions on which platform an application runs. So I think this is a compile time decision. Structs exist with the naming schema xxxA and xxxW. At compile time, depending on version statements an alias should be created. Shall i try to change that, so that there is version(ANSI) statement like this: version( ANSI ){ alias LOGFONTA LOGFONT; } else{ alias LOGFONTW LOGFONT; } 2.) I encounter not declared functions (AddFontResourceExW, AddFontResourceExA). Shall I try to add them to tango? 3.) DWT uses also gdiplus.lib, shall i try to add that binding to tango? module name?

It appears that Microsoft wraps the C functions with C++ (in the gdi+ headers) and publishes the C++ interface only (plus a very select number of C functions). There is no support for using the C interface directly. What this means is that it's possible to use the C functions if one figures out to do so, or it's possible to do some sort of a OOP D wrap (in light of the C++ version) of these C functions to achieve a similar goal. In dwt, I guess we'll need to wrap them somehow and figure out how to access the C++ members. Whatever we come up with may be useful for tango adoption.

Instead i added them as redundant copy into dwt. Now i can maintain them as needed, without the need to wait for decisions/responses of the tango win32-bindings responsibles. If someone is interested in removing this redundancy and/or fixing the tango bindings, please contact me.
