Re: [lazarus] Reducing Flickeron a TImage component
It seems, gtk_pixmap is creating the disabled image on-the-fly on first paint. So, the flickering is built-in. Because you change the image often, you see it often. Conclusion: gtk1+TBitBtn+disabled = flicker So the short version is - that GTK1 couldn't do what I needed (a dynamically updated but often disabled set of buttons with pictures on them) without creating a new component. It turned out to be far less work to just port this part of the program to GTK2, the rest remains GTK1 for now (there are three apps that make up the suite here) simply because fixing all the layouts etc. for GTK2 would take a LONG time (and worst of all GTK2 is still horrible with Z-order handling) but this part works just fine under GTK2 - and as per your predictions, the GTK2 version is completely flicker free. For the next OutKafe release (which I will start on after I return from this project on Friday) I will port it to GTK2 in it's entirety (it can be done now that SetWindowFulScreen works for GTK2) however.

Re: [lazarus] Zeos Lib Question
Lee, I had another look at this and found that Zeos is trying to use libsqlite.soto connect to sqlite3. So, I thought I'd change the code but then had endless trouble to recompile :-( and in my efforts to recompile I changed it back to what it was (lol). Anyways, in the end it was easiest to create a link /usr/lib/libsqlite.so - /usr/lib/sqlite3.so. It works like a charm. :-) Mmm, I just saw you were on Windows. This means I am confused again since the windows driver is specified as sqlite3.dll. Perhaps you could check that the installation of sqlite3 has its dll called sqlite.dll or sqlite3.dll.

I have many hints now: enough to keep me busy for many hours: --- My fstab does not say anything about .../floppy... That does not seem normal? It is in fact normal with many modern distro's (I don't know what you are running), there is no requirement even on older ones, but NOT having it there would mean there is no way to make the device user mountable (by default only root could run mount $DEVICE $MOUNTPOINT) --- My code does not have to be portable, but the users are Microsoft oriented and I find it very difficult to sell my Linux/FPC/Lazarus code. For me, opening the floppy before I run the application is easy, but for my users, it seems like an impossible task... Their next step would be to press the reset button ! I hear you, I often used to face the same issues, on most modern distros the floppy would open itself when inserted, I'm guessing this is NOT one of those. Assuming you can mount it with a simple command, I think the easiest is to just call the command from your app before running the dialog, another way would be to use the kernel automouter (there's a howto) which will mount the device whenever the mountpoint is accessed, and unmount it after X seconds inactivity. --- One colleague told me about mtools utility that will access the floppy without going through the file system. I do not know if there is a library or some programing interface? Mtools does exist, it is specific to dos floppies, it accesses them in a different way though. It can do things like copy files etc. Konqueror has a kpart which uses it so either it DOES have an API of some sort or you can read disks and manage their content pretty completely with the commandline tools it includes - if you wish to try this, I would suggest reading up on the mtools howto. --- Now I year all the laughs because I still use floppy disks: We still have an old network analyser (model 8510C) from Hewlet Packard: It is very old (1990), but very expensive to replace. It has a 720 kB flopy drive built in it. Any upgrade will be difficult because of compatibilty issue. I already feel very lucky that it will write on DOS formatted floppys. That explains it - no worries. If you let me know which distro you're using, I could possibly give more specific advice. A.J. Thank you all any way Alain On Wed, 2007-05-30 at 08:58 +0200, A.J.

My guess is that you've destroyed/freed SQLQuery somewhere before this code is called. Joost Not that, the SQLComponent is put on the form and no instruction exist for free it. Is it possible that a bug free a component without programmer ask to it ? A component is freed when its Owner is destroyed (in this case the form), so as long as you don't free the form or SQLQuery by hand, all should be ok. To track the cause of the exception, you probably need to get a stacktrace; e.g. use GDB or Lazarus itself. Hint for GDB: break FPC_RAISEEXCEPTION run ... bt You can insert ShowMessage of DebugLn statements to find out what your application is doing.

Sometime i can move move in list a long time before crash, sometime just two clicks in list are sufficient to crash. And never on a specific location in the list.

RE: [lazarus] Debugger on Mac OS X
Good point. But if the linker on other platforms complains about the OS X specific switches, you should be able to uncheck Pass Options To Linker box, correct? Here's the reference for what can go into the app bundle's Info.plist file: http://developer.apple.com/documentation/MacOSX/Conceptual/BPRuntimeConfig/index.html Some of the settings in Info.plist kind of overlap with Windows-type version resource info, hence the idea that maybe some of them could be set in Project Options | Version Info, although this would require a way to define any sort of string the way you can in Delphi, not just the limited version strings that it allows now.

[lazarus] Accepting Input on controls which don't have focus
Hi, I have a form with a TScrollBox and a TMemo. The TScrollBox has a TImage within it. The Purpose of the TScrollBox is to capture MouseWheel events (And also, it's painted black, the same colour as the TImage to reduce flicker). What I want is for the user's keyboard input to be reflected in the TMemo. However, if the Focus is set onto the TImage, the TMemo doesn't take the keyboard input, and visa versa, if the TMemo has focus, the Mousewheel events are discarded. Any solutions?
