Have you got the GTK1 Pixmaps theme engine installed (not just the themes). I had the same problem under Ubuntu. I could install Pixmap based themes, but no affect under Lazarus or any GTK1 based apps. After running Lazarus from the command line, GTK gave me a error message saying it couldn't find some pixmap engine .so files. Used apt-get, installed it, and now my themes work. :-) It will be really hard to get Mac OS X users to use apps that look like this. They want that all their apps look the same and that is true for me, too I'm taking it on step at a time and prioritising according to my current needs. At the moment I have no need for OSX support.

At some point I thougth about implementing it purely on LCL, but I discarted this option a little later. It was a implementation option. I don´t remember exactly the reasons, I think the reason you abandoned it is because you want to leverage existing code, which is fine. But you probably loose cross-platform compatibly that way, as each platform does it differently, unless you are really lucky. On linux, for example, message loops are done via IPC, as is shmem and mutex.

At some point I thougth about implementing it purely on LCL, but I discarted this option a little later. It was a implementation option. I don´t remember exactly the reasons, I think the reason you abandoned it is because you want to leverage existing code, which is fine. But you probably loose cross-platform compatibly that way, as each platform does it differently, unless you are really lucky. On linux, for example, message loops are done via IPC, as is shmem and mutex. So, what we need is an IPC component, that wraps the platform details inside the component, and exposes a platform-independent interface. but I can try to thing again about it. I got the impression, there is no short example for the need of AllocateHWnd. The only reason seems to be making it easier to port a special winapi IPC mechanism. Are there any other reasons?

If AllocateHWnd can be implemented (enough for Orpheus and graphics32) easily on all widgetsets, then let's do it. Otherwise we should think about using/extending the existing FPC/LCL IPC mechanisms. IMHO the idea of the LCLIntf is to provide those parts of the winapi, that can be done on all widgetsets without emulation. The rest is done with FPC/LCL specific functions.

On the other hand if portability is not an issue and simply users want to be able to run fpc/graphics32 programs under windows (I would be one of them :P ), then I guess, something must be done in win32 interface only, what needs to be done?, I don't know for sure, but see for one example the problem of user messages enabled only with a conditional, I never liked (in fact I implemented the part that enabled it) but the argument against it is the same: lazarus is about portability (and in this case I would add usability). When FPImage was implemented I thought it would be the solution to write software similar to what graphics32 allows to do, but in a portable way, I don't know it that reasoning was right though.

Think of what a widget set is (referring to the visual aspects only). It's a set of drawing instructions, to paint a component on a canvas. It's that simple. Now if you take the time with a custom written widget set, you can paint exactly like that. The end-user wouldn't even know. This is simply too naive. You can see the difference, although it might only one be pixel. the title bar (because the app was running under Linux). I believe later versions of QThemed actually hooked into the themes engine of WinXP, to do the painting without the need for composite images. Using WinXP theming engine is indeed possible, but will blow up your binary size, since you are including two painting engines then; regular windows and windows xp. Windows Vista is going to be different still, quite possibly. Implementing themes like Win2000, Win98 or Motif is even easier. I haven't yet seen a good emulation of those, though. Changing only the painting backend is much easier (100s of times) then writing a new widgetset interface. Of course it's easier; but IMHO it's also ugly/uglier. Uglier than the current LCL interface? With units like gtkproc or gtkwinapi, etc. ;-) gtkproc is probably helper procedures, gtkwinapi is implementation of common winapi functions for gtk ... Still I was talking about ugly in the UI aspect, not necessarily the implementation. The gtk interface is not pretty, and needs some cleaning, but that's life of any software project in the long run.
