It is useful in some situations and moreover I use this in my work projects when I want for example to integrate some form which may be a dialog in some cases into another form panel. So when form is manually docked with DragKind dkDock is not a bug in LCL and LCL should not change this property. But it's required to make the IDE dockable. If you oversve that some docked form should be undocked via mouse in IDE please change this in IDE. Not me :-( You need to find the control which changes the capture diring the drag and fix this control code. What do you need more than setting an breakpoint? Why should I do this if IDE docking has not 1.0 target? Because it does not only affect the IDE, but dragging in general. Consequently 1.0 will not properly support dragging, in all applications. That was your patch. The patch had target 0.99 and I reviewed it. The patch is wrong. If you want to fix IDE docking problems please submit another patch which does not break LCL behavior. I'm tired of supplying patches which then are rejected, and searching bugs in deliberately broken code. Docking worked fine in earlier Lazarus versions.

I'm not sure if you are having difficulty with this (maybe you just
haven't had the time yet) or even how it was implemented in the old
wiki. But my I make a suggestion. Why not implement a custom wiki
function like I have done with {{keypress}} (for keyboard shortcut
display), but for the roadmap status?
For example:
{{roadmap|w}}
That could produce styled text output such as:
span style=color:#FF; background:#00FF00working/span
thus white text on a green background.
{{roadmap|p}}
That could produce styled text output such as:
span style=color:#FF; background:#B7B104partially implemented/span
thus white text on a olive green background.
...and so for
The first parameter is one of:
w - working
p - partially implemented
i - in progress
n - not implemented
u - unknown
A quick search and replace can then get rid of the
'class=working|Working' type text, which seems more verbose anyway.
For more details on how I implemented {{keypress}}, take a look at the
following URL's.

O forgot to mention the content of ChangeOwner function procedure ChangeOwner(AComponente, NewOwner: TComponent); begin AComponente.Owner.RemoveComponent(AComponente); NewOwner.InsertComponent(AComponente); end; I suppose this function will handle all Notification changes, isn't ? That is not that easy to answer. That depends on who owns what... Maybe even which classes are involved. To answer that I would have to read through some of the RTL/LCL rcode myself. It is not even sure that the bug is related to this. Though with the bug in place, I would avoid changing owners. It is possible with workarounds, but I can't foresee all the pitfalls. I had a quick look at the LCL code. Anchors to not seem to use FreeNotify When the app crashes, use the debugger, open the stack and make sure the frame selected is pointing to the source you posted (it may already be) Then evaluate self and/or self.fname to see which components refers to the missing anchor. That should help you find out which control the anchor pointed to. Maybe that holds some clue. Then you can debug again, and set breakpoints (in TControl.Destroy / wit condition on FName), and trying to find when the other control gets destroyed (if that is the problem, there are other possibilities...) Sorry this answer may appear a bit vague. But tracking that kind of issue can be very hard. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Lazarus crashing reproducibly on startup (64-bit Linux)
Well, I've done a bunch of testing with some virtual machines, plus a bunch of web searches looking for other threads on this error, and it seems to be plain that it's a multi-way incompatibility. If you are running Linux Mint Debian Edition (LMDE) V12 on an AMD 64-bit CPU (and it doesn't matter whether you run a 32 or 64 bit version of the operating system) then Lazarus will crash, reproducibly, and that holds for any version of LAzarus between 0.9.28.2 up to a fairly recent svn version. If you're running on an Intel CPU, or a 32-bit AMD chip, or you're running the Ubuntu-based version of Mint, you won't have a problem. This is particularly puzzling since LMDE is built on Debian testing, and Debian testing will run Lazarus without a problem. For that reason, it seems to me that it's a problem for the LMDE folks rather than the Lazarus developers. Now, where did I put that Debian installation DVD? Brian.

While I've had one reply from a posting to the Mint Debian forums from someone who is tracking the unstable repositories and is able to run Lazarus without a problem, there seems to be no doubt that there is a basic incompatibility between Lazarus and either the stable or testing distros of Mint Debian. I haven't been able to get Lazarus to start on either distro, whether 32 bit or 64 bit, but plain Debian stable or testing runs Lazarus just fine. I'm going to try pointing at the unstable repositories now, and I'll post again in 3-4 days when I've had time to do the final set of updates and try all the different permutations. For the moment, I strongly advise anyone who wants to run Lazarus *NOT* to install Linux Mint Debian. If you want a rolling distro, stick with plain Debian rather than the Mint version, or try one of the others. All of the above does NOT apply to the Ubuntu-based versions of Mint. They run Lazarus without problems, too. Brian. On 03/18/2012 08:36 AM, brian wrote: I've recently switched distros to Mint Debian 12 64-bit XFCE. This is on an AMD Phenom *4, 4 GB of RAM. When I was reinstalling stuff I noticed that the latest version of Lazarus that they have in the repo is 0.9.28, a bit old I know, but it works for what I do. So I installed 0.9.28, which also brought in FPC 2.4.0-2. When I try to run Lazarus from the menus, I get the splash screen and then nothing, the IDE never comes up. So, I switched to a terminal, ran startlazarus and got the following output. [WARNING] Out of OEM specific VK codes, changing to unassigned [WARNING] Out of unassigned VK codes, assigning $FF TLazarusManager.Run starting /usr/lib/lazarus/0.9.28.2/lazarus ... Runtime error 203 at $00736A16 $00736A16 $00720991 OK, maybe it's an old version. I downloaded the latest .DEBs from SourceForge, and installed those. No change in the symptoms (well, OK, I can't say the addresses were exactly the same, but the bit about the VK codes was, and it was still a runtime error 203). I cleaned out everything to do with Lazarus and FPC that I could find (using KFind to make sure I got everything) and had one more try with 0.9.28. As expected, still the same error. I know that 0.9.28 used to run on Mint 9 64-bit, but that was the Ubuntu-based version, not the Debian-based one. Anyone have any ideas how to fix this, please?

Re: [Lazarus] Is there a function that returns UTC time in FPC or Lazarus?

Frank, You could search the fpc and lazarus mailing list; I know there've been posts regarding this. IIRC, the conclusion was that doing this is potentially very difficult to do cross platform, keeping daylight saving changes etc in mind. There is a separate unit that deals with this, IIRC, the wiki mentions it somewhere..
