I would try to automate it with Delphi converter but I don't know much about graphics programming myself. I am testing the converter with DeleD 3-D program which would be an extremely cool porting project. On January Birger Jansen wrote: Project conversion Delphi - FreePascal: success! which mentions OpenGL so it seems to be possible. Juha Hi Juha, IIRC, Freepascal/Lazarus uses the units GL.pas, and GLU.pas as opposed to Delphi's OpenGL.pas. I think this is correct, and I hope this helps :) cheers, Paul -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] More thread questions.
Hi Frank, AFAIK, a thread WILL execute immediately exiting the Create method unless you pass False to the suspended variable in the create method, and call Resume in the main thread later on. I don't think resuming a thread will never do anything if the threads execute method has fallen through, but people can feel free to correct me on this :) cheers, Paul - Original Message - From: Frank Church To: Lazarus mailing list Sent: Tuesday, July 13, 2010 1:42 AM Subject: [Lazarus] More thread questions.

I think it would be helpful to hide all comments at times, because while helpful, they make reading the actually working code a lot harder.

I know a number of people who would be interested in your delphi converter, including myself :) Good to know! (Although it is not really MY converter, but I am willing to improve it.) An easy to use 3d modeling package has now gone open source: www.delgine.com https://sourceforge.net/projects/deled/ The project has currently been written using Delphi, but some of us would love to be able to convert it over completely to Lazarus/freepascal so it is multi-platform :) This won't be easy as there is a LOT of delphi GUI forms and frames there, but it would be great if this could be done. Wow, such a good test case! I became curious and downloaded it and converted to Lazarus. Conversion worked better than expected. All the forms I opened looked good. My patches for converter make it less verbose, not asking so many trivial questions. Now I see it still asks too many questions, about non existing units and properties. It should be made configurable to be fully silent and automatic. Excellent! thanks for trying :) Please, continue to use this as a test case if you wish :) perhaps your delphi converter improvments could help us in this area :) Yes, the amount of questions is more reasonable now but there are still many things to improve. good to know Please remember that you still must make (lots of) manual changes to make your code compile and work. The converter doesn't try to fix windows dependent code or such things. In your code I see at least 2 things that need porting: OpenGL and jpeg. There is support for both in FPC/Lazarus (GL and pasjpeg) but I have no idea how difficult the porting is. At least the windows handles will not work. Yup...you are right about plenty of manual changes :) I knew about windows dependent code ;) The OpenGL should be only a minor issue to fix. Thanks for the info about the windows handles! Keep up the great work :) Perhaps I should try using lazarus from SVN instead of binaries and try your patch? I hope I can develop the code for trunk. That would allow interaction with people who use it. Besides the isolated patches can end up being ignored forever, that's how I feel now... OT Your code has very many units. How did you solve the circular reference problem? I didn't make any deep analysis of your code but it looks clean. I could expect there are lots of cross references in such 3D design prog. Or, maybe there are some units full of type casting but I missed them. /OT I haven't looked closely at the code in regards to the circular reference issues either LOL I guess units have been put in the implementation section to get around this issue as like you, I haven't noticed much type casting yet. And as you might have guessed, it isn't MY code either LOL I HAVE contributed to it, but that is all ;) Regards, Juha Manninen -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus Is there anyway I could try out your Lazarus delphi converter improvements?

[Lazarus] Lazarus minimization and code editor maximization issues
Hi all, I'm running Lazarus 0.9.28.2 (Win32), and have noticed two issues... 1.When I click on the minimization button on the main Lazarus program window, more often than not, only the top part of Lazarus minimizes...it leaves the editor window, messages window, etc. still there. This means I have to alt-tab to move away to the program behind Lazarus, and not just using minimize. 2.When I click on the maximization button on the code editor window, it maximizes over the top of all other windows in Lazarus, and doesn't stop underneath the top part of Lazarus like it does in Delphi ( I do realize this is NOT Delphi...LOL ) I love Lazarus, but these 2 issues really annoy me :) Any ideas or tips for me? cheers, Paul-- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
