Windows and Mac has it easy, because there is one governing body and a lot more standardized. Everybody keeps going on about how easy it is to install software on Windows or Mac.

The average Joe simply doesn't know how to install software on Linux and they hate the command prompt.

[Lazarus] lazarus editor coloring
Hello list, I've noticed two things that are missing at Lazarus: 1. The ability to add/save new color style I'm making 2. Loading custom made coloring I always change the default coloring of Lazarus to extended the coloring, however I can't save it as a new coloring style. Moreover I've noticed that on a darker places, a light editor is harder to work, and on a light place, a darker editor is harder to work with, so if I could replace such colors depending of my needs (that's where the saving come handy) it will be much easier to work with the editor imho. Now the big question is, how do I add such feature to Lazarus ? What exactly does it require and what points do I need to know before doing such thing ?

Things that need to be addressed: * For one, I think the color scheme information should go into a separate .xml file and not be part of the editoroptions.xml file. * I also think a runtime loading of color schemes is required. Lazarus comes standard with 5 or so, but when Lazarus starts up, it should also check a directory (eg: ~/.lazarus/colorschemes/) for any custom schemes and populate the scheme combobox with those too. * If previously you used a custom color scheme and one restarting that scheme is not available, it should fall back to one of the default color schemes include with lazarus (always available).

That's the crucial difference between Linux and windows in that regard. * The setup must be configurable at runtime. We have a single setup.xml file that controls the setup. (Doesn't this violate single file?) No, not from the end-users point of view. After creating the setup, one further step is taken using the tool 'makeself'. The setup files (setup binaries, data, setup.xml etc) are packaged with makeself into a single self-extracting file. This is the file that the end-user will download and run. Makeself also has the feature that once unpacked, it can run a command - in our case it will fire off the executable of the real unpacked setup files. Once the command makeself executed is done, it even cleans up after itself by removing the unpacked temporary files. Clear. But if it is internal and not user adaptable, all communication must happen (be possible) via the cmdline. Do you plan to support windowmaker? A lot of packages do this wrong under Windowmaker. If Window Maker supports the LSB or freedesktop.org standards it should work. A quick search on Wikipedia says the last stable release was in 2005, so it might not support the latest desktop standards. I'll make a note and double check for you. Make it at least pluggable, so that if you need to support some odd ball desktop, you can at least run a script or binary to install the link.

OK, I found my problem. It was code I ported from Delphi 7, and the usage of the cursor is slightly different for Lazarus. I used a stack to push pop cursors onto while opening nested modal dialogs and then restore them as the dialogs close. It was a test app of mine. But all is working again.

No, it would appear not. Nevermind, it turns out it's only called at the start of the idle handler in any case, so if the application is idle, it's no better than me polling with a timer. Surely there is a cross-platform, threadsafe way for me to alert the main thread there is something I want it to respond to *now*. Oh well, I'll keep looking.

Traditionally I'd do something ugly like have a timer polling a variable used as a flag, or polling a RtlEvent on a short timeout, but this seems like a much nicer solution. After reading the source for TThread.Synchronize() I see it already implements the round thing with spokes and a hub that I've been so busily trying to re-implement.

Luiz Americo Pereira Camara wrote: Is there a way to retrieve the version info that is stored in the project file at runtime? Instantiate a TProcess class and execute 'app -v' (obviously your app needs that command line param support) and read the output. This is the safest way and most cross-platform way I could find. I simply ignore the version information tab in the Project Settings dialog, because it only works for one out of all the supported platforms (windows). You can even have a command line parameter that outputs similar version information as that tab, but in the format key=value, so when you read that output directly into a TStringList, it is even easier to parse and use.

I couldn't find a way of formatting the date and time to my locale (under
Linux, not sure for other platforms). It seems to be hard-coded, so you
will have to parse and format it manually.

[Lazarus] DBGrid highlighting certain cells
Hi, What is the recommended way of highlighting (by changing cell background color) certain cells based on there display value? In Delphi I did the following: * DefaultDrawing = False * OnDrawDataCell I implemented the following. Check for criteria, then set Brush.Color Then call DefaultDrawDataCell This saves me the trouble from having to manually draw everything like the background color, border, text etc... Unfortunately this easy method is not possible with Lazarus, because DefaultDrawColumnCell doesn't paint the background (only text), it is done somewhere else (not sure where). Is this an oversight, or by design? If by design, what is the recommended way of doing this?

I can create a class which will retrieve all the written info from the version resources. There are no big problems here. The only question I have whether it is a part of LCL or more belongs to RTL/FCL?

[Lazarus] FTP Server component?
Hi, I looked at lnet and TurboPower IPro components and only saw FTP Client components. Anybody know where I could get a FTP Server component? Alternatively, a free or open-source FTP Server application that can run on Windows XP or Windows Server 2003 would also be great. Linux already has decent FTP servers available. Why? We transfer a lot of files (huge amounts of data) over our internal network. We tested performance between Win - Win and Win - Linux systems using Samba or MS Network Neighbourhood. We then tested Win - Linux using FTP and the transfer speeds where a LOT better! This speed increase makes sense because FTP is a specific file transfer protocol, where SMB is mixed bag: file sharing, printer sharing and lots of other communications we don't need.

The recommended way is using OnPrepareCanvas DbGrid event. In Delphi I did the following: * DefaultDrawing = False * OnDrawDataCell I implemented the following. Check for criteria, then set Brush.Color Then call DefaultDrawDataCell This saves me the trouble from having to manually draw everything like the background color, border, text etc... Using OnPrepareCanvas you don't have to draw anything, you get the column:tcolumn which is being painted as an argument and from there you get the field and can take decisions based on fields value, then you change dbgrid's canvas properties, for cell background you will have to adjust grid.canvas.brush.color, font changes can be made on grid.canvas.font, alignment, etc. for borders one needs custom drawing and OnDrawColumnCell is needed, OnPrepareCanvas do not help here. Unfortunately this easy method is not possible with Lazarus, because DefaultDrawColumnCell doesn't paint the background (only text), it is done somewhere else (not sure where). Is this an oversight, or by design? I think until now nobody noted the problem, probably this feature is not used too much. But IIRC, the background was supposed to be painted in OnDrawColumnCell and then you call DefaultDrawColumnCell, I might have mis understood how this works, I need a good test case. If by design, what is the recommended way of doing this? Although with OnPrepareCanvas we cover most of cases where this feature is needed I would like to make it Delphi compatible, if possible, please submit a bug report.

Yes, because resource support in fpc made in a 'windows-like'/'delphi-like'. Nothing bad in this but work with resources requires knowledge of windows structures which are used to store different resource info into executable.
