It is clearly a bug somewhere in the LCL-GTK2 widgetset, because other GTK2 applications like Mozilla Firefox, Thunderbird, Nero for Linux, gEdit, Nautilus etc all run fine with acceptable speeds. No, Firefox (or specifically Debian's rebranded version which they call IceWeasel) does NOT run with acceptable speed over a remote X session, although this might in part depend on the hardware platform. I'm afraid I can't test this in detail at present due to Debian self-destructing after an update to one of my development systems, but so far it appears that I get exactly the same combination of problems as we've previously discussed with Lazarus. I was going to comment on this publicly after I'd tried to characterise the Mozilla problem a bit more, but at present I'd suggest that it's either a bug inside GTK2 itself or is associated with a particular way of using one or more GTK2 facilities.

Re: [Lazarus] Open URL in default browser X-platform
Bart wrote: Hi, I come from Windows/Delphi (3.0) background and I'm gradually moving towards Lazarus/fpc. Opening an URL in Windows is a piece of cake, you just let the OS take care of the assotiations with the http protocol to open it (using shellexecute). This of course will not do for other platforms. So I set myself the task of launching an URL in an external browser on other platforms. Since I only have Linux (besides Win) I began with that. I tried to find examples on the net, but had no luck. I might well be re-inventing the wheel though... Here's my approach: - try to detect the windowmanger (for now I know how to do this for KDE and GNOME, XFCE is on my whishlist) On KDE - lookup DESKTOK_LAUNCH environment variable - if not there, look for kde-open - if not there look for kfmclient - if not there look for xdg-open - if not there try fallback (possibly using gnome-open might also work under KDE ???) On GNOME - look fo gnome-open - if not there, look for xdg-open - if not there try fallback Fallback - search for know browsers (firefox, iceweasel, mozilla, opera, konqueror, ...(suggestions are welcome)) If browser (or URL handler like kde-open, xdg-open etc.) is found launch it with the appropriate URL. This approach (the finding mechanism) seems to work at least on my Suse KDE desktop. I would like your opinions on this approach, and better still, I would like some suggestions how to achieve something similar on a Mac. (I suppose on Mac OSX the linux approach should work also???) And as a final rather dumb question: do all supported OS's have an environmentvariable PATH (as this is used in the fallback mechanism)? There's already a standard for that: xdg-open. Granted that a fallback for older distreaux that don't include it is useful, but apart from that rather than trying to reinvent the wheel your time would be better spent cooperating with the people who've implemented it- I'm sure they'd appreciate your help. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Linking to an arbitrary DLL (libusb-win32)
Out of curiosity I'm trying to press ahead a bit further with linking a
Lazarus program that runs successfully with libusb to run instead with
libusb-win32. I know that there will be runtime problems since I'm
trying to run on NT4 but I'm interested to see to what extent I can get
additional error messages etc. out of the system.
When compiled for Linux I've got a simple unit UsbIf that calls Uwe
Zimmerman's translation of libusb.h which includes
{$linklib usb}
..
procedure usb_set_debug(level: longint);cdecl;external;
On the Windows systems the DLL is libusb0.dll and in principle I've got
.h files etc. available. When I compile I get
Error: Import library not found for usb
..
Error: Undefined symbol _usb_set_debug
It's 20 years since I've played with import libraries, and before I
start tinkering I need to know that I'm not heading off in the wrong
direction.
This is in no way important, but what should I be doing to get this to
link against the available DLL?

You shouldn't need libusb for that, the usb-serial converter should work right out of the box (most of them do nowadays) but instead of using /dev/ttyS* it will (most probably depending on udev rules) be assigned to /dev/ttyUSB*. I use synaser (http://www.ararat.cz/synapse) to program serial communications in a cross platform (at least win/linux) way. I agree that access to the ports shouldn't need anything other than /dev/ttyUSBx, but in the case of monitoring there's a need to get accurate timestamps on every character and signal transition which complicates things. As a result any possibility of improved resolution is worth pursuing.

That was certainly not my intention and I apologise without reservation to anybody who took it that way. However if somebody had said C# won't do what you want because it doesn't have a decent form designer or integrated debugger it would certainly have reinforced my preference to stay with Lazarus. I understand your position and the original message now, and to explain my reaction, we get some people here which when their personal needs are not met (usually bussiness driven people), end up being all negativist about the project and start a sort of mini-war about how they'll go to insert other project here and how ours sucks etc. usually very immature reactions. My position is that if somebody wants a feature in a piece of open-source software and has commercial resources they should sponsor its development with a bounty. I've never said I want this feature, I admit that I have rather thrown my hands up in horror when something doesn't work (e.g. hiding the menu bar in gtk1), stops working (SPARC in 0.9.26) or is implausibly slow (e.g. gtk2 to a remote X screen). If somebody doesn't have commercial resources they should use their free time to learn how to add the facilities they want. If somebody has neither commercial resources nor free time I guess a bit of charity is in order, but they certainly shouldn't /demand/ anything :-) As to the problem of Gtk2/LCL speed, it's still quite possible there's a bug in LCL which does some unnecessary drawing/signals in gtk2 (this was so in the past, but on my end/setup was fixed). I don't think that speed is really the issue. The Big Freeze after mouse movement is far more serious, and using Wireshark I've not seen LAN traffic during this- I might be wrong and will revisit if I've got time. Many people get problems with remote lazarus tho, but I'm not sure if it's only Lazarus/LCL or also other gtk2 programs. I think it's specific to Lazarus in this case since I've not seen other problems with Debian Lenny which defaults to gtk2, and I almost invariably run this to a remote screen. It could be some rarely-used facility in the gtk2 libraries that is only being used by the LCL, but that is tantamount to saying it's a Lazarus problem. Also as I said before, gtk2 performance in general depends heavily on many aspects including the drivers, theme, it's version and settings in X.org (for examply my miraculous speed is actually result of using the EXA accelmethod). Understood, and I think that the significant difference in gtk2 performance between the two machines I was using as X terminals (I prefer that term because so many people get confused by discussion of what a server is in this context) suggests that at least part of the speed issue is dependent upon properties or facilities negotiated between gtk and X. However as I've said I don't think reduced performance is the significant issue here. Going back to your earlier question about display types, both systems that I was using as X terminals for test purposes are probably far too old to have significant hardware acceleration- certainly as is understood today. The IBM PC-310 is reported by lspci to have an S3 86C864, the Sony Maiow is reported by NT to be a NeoMagic MagicGraph 128XV; in both cases they are operating at 1024x768x16 (I think) and have about 2Mb RAM. Obviously the video in Sun systems is custom, there are issues on that platform about what kernel versions support acceleration for GLX that I think aren't relevant to the current discussion; the IBM has a Savage which again has acceleration issues which I don't think are relevant since in general I'm not using it as a display device. The remaining Compaqs have onboard video, I might be able to replace the 3000 with something marginally newer from our hardware store but I don't think the details are relevant. I need to press on with a bit of USB hacking to keep people happy at this end, I'm also trying to revisit 0.9.27+gtk2 on SPARC. If I can I'll try to look at the menu bar issue with gtk1, but the Big Freeze almost certainly needs more familiarity with the LCL's innards than I will be able to build up in finite time. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

What I don't like is when people try to sort of blackmail their problems into attention by statements like you did before regarding we'll be forced to go elsewhere. This isn't a demand driven development model, bugs are fixed on personal mood/itch basis, not on someone customer needs (although majority and critical bugs obviously get more attention). So if you think your money/time is best spent elsewhere, fine, but don't make a crybaby out of the decision. If you decide to stay and help with the problem then even better of course :) NOTE: opinions here are my own Fair enough, but I think that puts me in a position that I need to state my policy and that of the people I work for and with. My policy is that I would prefer to build up enough competence in Lazarus and FPC to be able to make a worthwhile contribution to them. Our policy is that we don't want to be forced into supplying equipment and services to our customers which carry unfavourable technical and contractual baggage. Roughly translated, we don't want to embed MS OSes in x86 kit unless it really is inevitable :-) We need to eat, and if it gets to the point where the time I'm putting into dragging myself painfully up the learning curve prevents me from doing concrete development and system management that is going to be a problem. Fortunately I don't think we're particularly near that, but I regularly find that real work intervenes in things that are far more interesting and knocks me offline for days or weeks. I think you are being slightly unfair characterising Lazarus, and by extension other open-source projects, as being driven entirely by goodwill rather than by enlightened self-interest. The bottom line is that we like Pascal-style languages, we value the integrated design and debugging that Delphi championed in its days of glory, and for a whole lot of reasons we want those facilities on platforms that Borland never took seriously. Now I'm trying to do my bit keeping things going on SPARC, in part because it's a representative non-x86 architecture so is worth attention but also because- at present- it's comparatively easy to get SPARC-based systems which go rather larger than x86-based. Finally, I would thank you not to mis-quote me. You claim that I wrote we'll be forced to go elsewhere. I did not write that, what I put was I'm in a position where I find myself wondering whether I should start looking at C# or possibly Embarcadero's current offering which I think is fair comment.

I'm not saying that gtk1 is a good choice, but with the performance of the gtk2 IDE to a remote screen it is, regrettably, an inevitable choice. If a gtk2 program takes 13 seconds to run on a local screen against 3 for gtk1, well basically who cares? CPU power is cheap and users have to go with the flow- in just the same way that sooner or later they will have to abandon KDE3 in favour of KDE4 even if the user interface is unfamiliar and some facilities have been dropped. If a program is slow on a remote screen then users will just have to abandon that way of working- and while we're at it shouldn't we just recognise that X is obsolete and go straight to the hardware? Look, I'm sorry but as long as both gtk1 and gtk2 are supported as standard- and particularly while gtk2 is marked Beta in 0.9.26 which I believe is the promoted stable release- it's just not feasible to brush UI and performance issues under the carpet. The fact is that users and developers won't change their hardware and way of working on a whim, they don't even do that without a lot of kicking and screaming when the whim comes from Microsoft.

It was myself who experienced the speed problems. I tried to post them 4 or 5 times but the mailing list rejects my emails - I will try this once more. As a test project I have been porting a WinCE (ARM) application I first wrote using C#. It's for PocketPC. The C# version was compact but sluggish in operation, so I rewrote it in old fashioned vanilla C, directly to the WinCE API. This also produced a compact executable, and the execution speed was excellent. The downside is that development is painfully longwinded. While the C version of the app works just fine, I will at some point want to extend it, and Lazarus looks to be a far better development environment. And indeed, it is. I've been very impressed with it. Most development was using the emulator, but when I copied it over to the PDA for the first time I was shocked by the performance. It's about 10 times slower than the C# version, which already was too slow. I knew the executables were going to be large, and accept that as a penalty for the very much easier development.

[Lazarus] Performance of GTK 2 and CE
I can't help notice that IDE 0.9.26 compiled for gtk2 crawls, I've not yet investigated the speed of gtk2 apps. Is this being slowed down by debugging code, and is there a compile-time option to disable this? Somebody I know started experimenting with Lazarus for CE a few days ago but finds the performance unacceptable- vastly slower than C#. Is this likely to be caused by debugging code, and again can this be disabled- preferably without having to recompile the IDE? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

If any test takes more than few seconds, there's something wrong, either your theme, or your driver. Gtk2 isn't the fastest kid on the block, but it's not that slow either, if the drivers perform.

The only instance I'm routinely using VNC is to a Win-32 box I use for Delphi and as a client to the CIX conferencing system. I'm obviously connected to my Sun desktop system (Debian Etch) directly, apart from that almost all other Debian and Slackware systems are accessed over X. The remaining exception to the above is a SPARC system that Vincent was tinkering with- I think he's using X for that rather than VNC, but I'm not sure what combination of libraries he's been using. The latter I can confirm as dog slow. Over a 1 Gb lan it takes minutes before the cursor moves one char in the editor. (Responses to mouseclicks on dialogs take the same time btw) This resulted for me to continue laz development using a gtk1 IDE. That's much what I'm seeing, I similarly concluded that it would be better for the moment to continue with the IDE built for gtk1 but I assumed that there was debugging code in the system which at some point would be removed. If my assumption was wrong then I am troubled. One thing does occur to me however. If I fire up a system based on Debian Lenny, which I believe (somebody please correct me) is based on gtk 2, I observe that Gnome itself runs adequately over a networked X connection. In other words, this problem is specific to Lazarus operating over a networked X connection, not to gtk 2 itself. When using a VNCserver, it should work more smooth, since all is handled locally and only display changes are copied ove the LAN. I'll investigate, but the number of systems set up here for VNC is limited unless it's needed for something special. In general I simply enable gdm with xdmcp and everything works fine.

[Lazarus] 0.9.26 (FPC 2.2.2) on Slackware and Debian
I've set up a rather elderly Compaq here specifically for a number of jobs where I expect to have to wipe it and re-install if necessary. On it I have Slackware 12.1 and Debian Lenny, largely so that I've got gtk2 etc. If I install the binary of FPC 2.2.2 on Slackware I can compile Lazarus (both all and bigide) from source without problems. If I do exactly the same on Debian I have to add libgdk-pixbuf-dev (no big deal) but then to get Lazarus to compile have to add a handful of symlinks: libatk-1.0.so - libatk-1.0.so.0 libpango-1.0.so - libpango-1.0.so.0 libgmodule-2.0.so - libgmodule-2.0.so.0 libgthread-2.0.so - libgthread-2.0.so.0 libglib-2.0.so - libglib-2.0.so.0 libgobject-2.0.so - libgobject-2.0.so.0 libgdk-x11-2.0.so - libgdk-x11-2.0.so.0 libgtk-x11-2.0.so - libgtk-x11-2.0.so.0 libgdk_pixbuf-2.0.so - libgdk_pixbuf-2.0.so.0 where libgdk_pixbuf-2.0.so.0 - libgdk_pixbuf-2.0.so.0.1200.11 etc. I presume that this works on Slackware because the symlinks already exist, and can confirm: libgdk_pixbuf-2.0.so - libgdk_pixbuf-2.0.so.0.1200.9 and so on.

Mark Morgan Lloyd wrote: 0.9.25 compiled for Win-32 running on NT allows you to hide and unhide a form's main menu depending on the visibility of the items on the menu, i.e. if nothing's visible on the menu then it doesn't take any space on the form. When compiled for gtk running on Debian Sarge x86 the menu is hidden as a thin strip which expands to its full height when items on it are made visible but cannot be hidden again. I was hoping that compiling Lazarus on Debian Lenny, which I believe is oriented towards gtk v2, would fix this. However it appears to require the libgdk-pixbuf-dev package which still appears to be based on gtk 1 and appears to install libglib1.2-dev as well as possibly splurging symlinks into /usr/lib. I tried building for Qt but Debian is still on v3.5 rather than v4, and fpgui also failed. I've got nothing against gtk 1 as such, but am interested in seeing if this menu problem is tied to a particular widget set since it impacts on some stuff I'm trying to lay out. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Event editing on ARM Linux
0.9.25 compiled for Linux on ARM (little-endian) appears to have a problem with the event editor. If I put a button on a form then double-click on the OnClick event I get a messagebox Unable to find method. Please fix the error shown in the message window. The message is Error: source not found: unit /usr/local/share/lazarus/lcl/units/arm-linux/stdctrls.ppu. I admit to being rather inexperienced on that particular platform but I think I've set it up the same as other systems.

[Lazarus] Help viewer
Looking at lazhelphtml.pas, I suggest it might be worth adding seamonkey immediately before netscape. This is the integrated bundle of HTML viewer and mail client which supercedes Netscape. It's probably not necessary to add iceape and iceweasel which are rebrandings of Seamonkey and Firefox since they'll be found by xdg-open which was introduced at about the same time.

However I can't do much real work on this platform- compilation on the hardware available is somewhat sluggish and while I've got some higher-spec boards (or could cross-compile) it all takes time which is in short supply.

To me, this seems to be a compiler bug. Line 230 is:

FReference is an object with a boolean property Allocated. I see no
reason, why this should give a problem.
Can you try with fpc 2.2.2?

Re: [Lazarus] Is this a new microsoft approach?
Graeme Geldenhuys wrote: Simply allow configuration files to be written in the users HOME folder, nowhere else, unless you are Admin — how difficult is that! You don't need this virtual crap. I think the virtual business was probably inherited from MS IIS which had virtual directories (e.g. some location in the filesystem corresponding to http://localhost/). I don't like configuration or state files that are written without warning, what I do if I want to save (for example) a list of recently-opened document names is use a file named like ~/.myapp.ini (for unix, or a hidden file in the user's profile directory for Windows) but only if it already exists and is accessible. However the real problem is where programs have been written assuming files in hardwired default locations which in retrospect were inappropriate despite being compliant with MS's recommendations. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Current version?
Over the last couple of years I've been tinkering with Lazarus on i386 (Windows and Linux) and SPARC (Linux), I'm mostly using 0.9.24 on FPC 2.2.0. I'm currently trying to get it running on ARM (Linux, little-endian). What is the current preferred version for non-core users, in terms of being reasonably stable but with problems being of interest to the core developers? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Then comes 0.9.25 with revision 15471. The current 0.9.25 has currently some image problems, otherwise it is the best of all lazarus. Mattias, Joost: many thanks. I might be safest sticking with 0.9.24 + 2.2.0 for the moment since the Windows development machine is NT and I've previously seen problems. I'll have another shot at building for ARM and raise any issues in a separate thread. Later I'll try moving to something newer than 2.2.0 on all platforms and then 0.9.25 or later. One of the things I'm still trying to find time to look at is problems when a project is moved between x86 and SPARC which might be related to endianness. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Bringing a form to the foreground
Is there a portable way of bringing an application to the foreground, specifically so that its Do you really want to quit? dialogue is immediately visible? The scenario here is that when running under KDE if you click on an app's frame's close button or Right ClickClose on its taskbar button it doesn't bring the app to the foreground, so the dialogue is hidden. I know that arbitrary focus changes are deprecated, but this is one of a small number of cases where it's justified. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
