<body class='hmmessage'><div dir='ltr'>Hi guys. <div><br></div><div>I am working on porting a Windows application over to Linux, and my hope is to use Wine to make that go as quickly as possible. In my research, I have found one possible hangup, and hopefully you guys can answer it in a few minutes, vs the week or so of work for me to test it out myself.</div><div><br></div><div>Long story short, I have an application which creates child HWNDs. The application also launches separate processes. When WM_PAINT messages come in for those child HWNDs, it passes the HWND to one of the other processes, and that other process is the one that actually draws on it.</div><div><br></div><div>This works great on Windows. But I have found out that Wine only makes XWindows for top level HWNDs. So my question is: Can an application in wine perform operations (like drawing, BitBlting) onto a child HWND owned by another process?</div><div><br></div><div>Any tips or guidance you can give will be greatly appreciated.</div><div><br></div><div>Best regards!</div> </div></body>
