I will fix this in lazarus. If we look at winapi definition then
typedef struct tagNMLVCUSTOMDRAW {
NMCUSTOMDRAW nmcd;
COLORREF clrText;
COLORREF clrTextBk;
...
}
In lazarus definition NMCUSTOMDRAW fields are moved from nested record
field into TNMLVCUSTOMDRAW itself.
Ah, now I see. Note that the winapi version is already in commctrls. It
doesn't need redefinition
- comctrlversion* constants are not known in the SDK. What are these?
- DSC_ constants are unknown in SDK (DSC_MODAL, DSC_MODELESS)

notes:
- cdrf_NOTIFYITEMERASE not available in SDK 6.0!?!?! - added for now
anyway, since some other constants (swp_*) have comments that defines
from wine were added.
open msdn for NM_CUSTOMDRAW (list view) and you'll see CDRF_NOTIFYITEMERASE
(I grepped the headers of a SDK (6.0) dled last week. No match. Note that I
copied it anyway)
My full notes of the conversion is here:

I found this:
swp_* new items added, one not in sdk, but comments says it is from wine.
Comment actually says that this one value is not documented, but windows
itself uses it. IIRC name of this const has been taken from wine since
there is no official name for undocumented const :)
Yes, but it was good enough, it is copied.
I'll merge these changes to 2.2.1 today, since they mostly are nearly only
constants, and then the symbols can be removed/ifdefed from win32extra.
Big thanks.
They were merged to 2.2.1 yesterdayevening, and since your comments don't
need more changes FPC side, I guess Lazarus can start changing when they
want.

Take Pixel (the image editor) as an example - It looks like Windows XP default theme, but at closer inspection it's not (file dialogs are very different, no keyboard focus support, no mouse over/down states on buttons and scrollbars etc..) but it seems to be enough to fool the average user and make them feel okay with the application. For me it is simple. Despite that I'm multiplatform oriented, I can't wipeout that Windows is still dominant. Anything substandard on Windows is thus IMHO a dead horse except in certain niches. When trying to improve the behaviour when totally gets into the swamp of details, differences of approach, customizability etc. And with dead horse I mean the technique (the widget set), not necessarily the application (like Pixel), since that can have additional features going for it that make up for it. So unless I have a very strong reason I'll go for the native set. I'm trying the same with fpGUI - getting them to feel comfortable, even though some things might be a bit different. fpGUI's goal is consistency across platforms with the addition that anything can be customized if the developer needs it. And whatever I missed and somebody else needs - hopefully it will be fairly straight forward to implement. That is indeed a different vision. So you are more targeting the same user working on multiple platforms, then delivering an app to multiple users on different platforms. As for bleeding edge looks like Vista - 99% of ours clients use Win98 and WinXP (and yes I know I shouldn't generalize only on our experience). Only now (the beginning of this year) we finally stopped supporting Win95! People don't upgrade nearly as quick as Microsoft wishes! There is a lot of old hardware still being used with Win98. Yes I know. I've been in the same position. But those machines were dedicated to that hardware, and no new stuff was bought for that market. So we gave up on pre 2000.

One assumes here that a usability defects makes unusable per se. Which is false. Usability defects can be painful, but if it can be worked around, it can be still worth, depending on the gains. And there we get into the usual pattern. Not everybodies expectations and requirements are the same. If Lazarus could be as useful to me as Delphi 7, I would change my opinion from nice little toy, to amazing open source platform pretty quickly. Calling something a toy that people earn a living with, and other people invested over a decade in, doesn't gain credit points. Nor will they listen to your arguments. It's not that I hate Lazarus. I am deeply disappointed with it. All the whiners who stopped buying from CodeGear because of low quality, seem to have no problem with the low quality and the missing basic features of Lazarus that Delphi has had since Delphi 3.0. Maybe they still miss features in D2007 that FPC had in 1.0, like Linux support. Or multi-arch support like in 2.0 :-) Or generics, like in 2.2. You still can't install packages in Lazarus because the underlying FPC compiler lacks a runtime package system that could support a more delphi-like designtime/runtime packages installation system. Which by the way is the worst part of Delphi. Everyone complains about Delphi component installation headaches. To be honest, I use D7 daily. Mostly because in my current job I have no need for crosscompat atm. But in all my years of being a Delphi programmer, I never used packages, and in some ways the Lazarus package system is better (e.g. not having to manually add directories after installing a package, why couldn't that be fixed in 11 versions of Delphi?) If Lazarus develops ANY package support whatsoever, I'll contribute and help make it better. I only partially agree with Florian. I don't think a package system is useless, but it sure is overrated, and the costs are tremendous. It's that big hump that has stopped progres thusfar. Your messages is typical in this regard, and by the way roughly something that has been echoing in b.p.d.non-tech for about an year now as the lastest last-straw whip to bash Lazarus. Except the vague (and IMHO bogus) notation that packages is some silver bullet that will make Lazarus right, it doesn't provide any clue about usage patterns of packages, notion of implementation details, the question if versioning in an open source projects won't be awfully hard (364 1/4 .FPL packages every year. Minus one day when the server gets exchanged) etc etc. And of course, nobody wants to help. It must be there first, and then the same people will hold on to the next straw that FPC misses, something that has been going on since Delphi times (including one person that persisted that FPC is not there yet for ten years because it wouldn't compile his 16-bit asm) Personally I would rank debugger way higher on my wishlist than packages. But until the FPC base compiler supports some kind of runtime package support, I see no point working on the top level GUI (lazarus). Maybe I should try to help the FPC team write package support. I don't know if I can, I have zero compiler-writing experience. It's more linker knowlede btw. And we wouldn't mind. On a similar note, recently a new resources system was committed, mostly created by an interested external (thanks again Giulio) But may I suggest you should actually have a look at Lazarus internals beforehand, to really make sure you are not wasting time on a silver bullet that turns out to be rust? Another thing to think over is that if packages are less useful on non windows platforms, how useful is the package then? It will be some time that FPC beats Delphi in pure Delphi/win32 applications. Cross platform matters to me. So I'm not like most of the lazarus haters. I'm not a hater at all. But I am a critic. Uninformed critics are often awfully close to haters. Except the former word it better. That's not necessarily a direct crack at you, but be careful that you don't echo the tenure of that NG too much.

Yes I understand but why loose so many new users? All the programmers come from Delphi reports this issue and only a little subset of them check for a solution on Google. Others are lost!

Note also that such users typically don't know how to run shellscripts in the first place. But if a solution exists why do not use it? I do not understand! :( Well, you are right somewhat. Delphi has a separate VCL and a debug vcl for this purpose. However the core maintainers are a bit busy, so we would need extra resources for that. Maybe you should make a design document detailing how to do this, and most importantly, inventorise - the problems of having multiple LCLs in an eco system where the IDE is also using the LCL, - directory structure - distribution size (another such eternal size problem). Maybe an autobuilder (only distribute source?), another project, another document - how to configure in the IDE. - what should be default, - how to get backtraces (lineinfo) without full debuginfo, do we need a third type? etc etc. I'm sure if you spend some time on it, you can really do good here. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

When using the sockets library I'm getting compiler warnings such as 'Symbol RecvFrom is deprecated'. What exactly is something trying to tell me here, and what should I be doing about it? The old 1.0.x symbols have been deprecated in 2.2.0+, new variants exist that have proper typing and (standarized) errorhandling. These new variants are called prefix with fp, so fprecvfrom. These are all documented in http://www.freepascal.org/docs-html/rtl/sockets/index-5.html (though badly, they are not aliases, they are the real thing) The deprecated functions are also possibly buggy, don't use them.

The whole idea is that the end-users of a binary don't need the whole shebang. I agree. It is a compiler. So we shouldn't be afraid to ask it to compile an extra file for us. The issue is more about platform independance and download size. By distributing packages in source code and compiling them after download, it means quicker downloads and less time recompiling the whole of lazararus just to add in a new package. How is this different than e.g. fppkg ? - fpc/lazarus uses these library files just as it would internal functions... That is impossible. (or you use internal functions entirely the wrong way). Why impossible ? At compile time, the compiler could decide whether the function is internal ie within the lazarus library files, or external within the users library directory. Well, the compiler knows nothing about lazarus. But I have noticed that we are using the GNU ld linker and I have been exposed to that a bit in the past. I know what that thing can do and what it can't. (actually starting with 2.1.x/2.2 not on windows anymore) When I use GLScene in Lazarus, ld takes an enourmous amount of time to link. It is unbearable. ld is being asked to write in all the glscene code into the .exe and seems to take forever (15+ seconds). I would prefer to have the option to link against the runtime libraries dynamically. This would save so much time. Well, I actually don't know that, but it could be yes. But that would require library packages like Delphi has and is far off. Further, it is pretty unrelated to the source packaging system. As far as I am aware, it is only a matter of changing the command line parameters when ld is being called, and ensuring that all the libraries that are being linked against are in the correct directories. _IF_ you have a valid librarypackaging system (shared lib generation on pascal level) system. But this is maybe as big as a change as e.g. adding a ELF internal linker. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

It is, because there is no function to change this value in TXMLConfig.
The main purpose of TXMLConfig is to get and set some config values,
not to parse an XML document.
The question was more (since I'm not to deep into XML), if there was a true
notation to linearise this. IOW if some character is used to signal
nodevalue, or simply #text or so.
I'm no XML wizard, which is why I actually reused code instead of
writing my own ( :-))
So what would be (a) more normal rule to distinguish child values from
attributes?
The Document property gives full access to the internal XML.
I made the FindNode method public, so you can find the node easier.
I can't do much with this, since laz_xmlcfg (and the value=path) assumption
is a bit too deep into my framework at work, and this is only an exception.
But that is not a problem, I keep my hacky way, and don't merge it back.

In what way is the GLScene license non-GPL compatible? It's MPL, and it is designtime. Note that violation is a bit of a big word, specially since all people involved are on speaking terms. It is more meant as a testcase for the new policy. Specially because this is the exact example that I gave that started this discussion (MPL designtime) The first point would be to investigate if there is MPL code in the designtime parts. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] After compiling and debugging my app, sometimes (randomly) a failure pops up.

My setup: Windows XP Pro SP2, Lazarus 0.9.22, fpc 2.0.4 How to debug this irritating thingie? You could try to use this GDB command: set scheduler-locking mode Set the scheduler locking mode. If it is off, then there is no locking and any thread may run at any time. If on, then only the current thread may run when the inferior is resumed. The step mode optimizes for single-stepping. It stops other threads from seizing the prompt by preempting the current thread while you are stepping. Other threads will only rarely (or never) get a chance to run when you step. They are more likely to run when you `next' over a function call, and they are completely free to run when you use commands like `continue', `until', or `finish'. However, unless another thread hits a breakpoint during its timeslice, they will never steal the GDB prompt away from the thread that you are debugging. show scheduler-locking Display the current scheduler locking mode. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Re: [lazarus] History of the widget set design?

Yes. And because that is so easy, the look and feel of *nix is so much better :_) IOW, that is a stopgap emulation at best, and often doesn't adhere to global OS settings. I think it is much harder to get C++ widget sets to play along in our Object Pascal world than to modify some backend Object Pascal code. Except for QT I don't know C++ widget sets worth mentioning. The rest is all procedural interface.

Just try to convince somebody to use a Qt or GTK application on Windows or MacOS. They will tell you always it looks and behaves strange. Consistent Getting a native look is easy. QThemes (or something like that) was a add on unit for CLX which could make a Kylix application look exactly like XP (blue and silver themes) and exactly like a few GTK themes.

The other major concern that held me back was about how much disk space an SVN implementation consumes over time as it grows, and how big a backup of the SVN server data would be compared to my present method. What are your experiences? Way smaller _IF_ you commit carefully (don't commit slightly mutated binary files all the time. Our backup of 120 revisions together in .tar.bz2 are 120% of the size of the source as ZIP. Setting up SVN took about a day, including plugging a ssh hole in the firewall so it works from home. The biggest thing is figuring you need groupid permissions here and there. Including reading the book.

The linux machine is running Mandriva 2006 and does absolutely nothing at the moment other than serve a remote disk for backups. The app uses Synapse for networking and TDbf for it's data bank. I have never used Linux and have no idea about how it works. So here are my questions: 1) How do I (cross)compile a linux app from windows?
