At that time I never even wrote a single component of myself, so I really had to study the LCL and Lazarus code very hard. I then discussed these issues in the bugtracker with several of the devels and got very usefull feedback. This encouraged me to submit patches and some of them got accepted. I thinl that's how most devs started out. It was the same for me and FPC :) No need for VM images (which one could not provide for Windows at all). Note: Lazarus works more or less on ReactOS. So one could test how good it really works and then provide a ReactOS VM with Lazarus preinstalled.

The mailing list you are referring to is not listed at http://lists.lazarus.freepascal.org/mailman/listinfo and it is clearly not related to development of features as is generally understood.

Although they enable code displays to be better formatted once you have to follow more than a few different wikis and forums they are less convenient. This is an issue which has been well debated and I have no intention of raising it here. FWIW I have just spent over an hour exploring Mantis and it looks like the place where a lot of Lazarus development related discussions occur. Obviously it is a complex multiplatform system which is rather mature in internet years and has gathered quite an amount of cruft and I can understand why its developers prefer to focus on fixing existing issues rather than spending/wasting time debating new features. @Matthias and Bart - I think it helps to open up the more technical discussions to outside viewing.

Re: [Lazarus] Alpha transparency on GTK2 widgetset
Nice job. I had a different approach in mind, but that required a rewrite of gtk2devicecontext and a lot of cairo stuff. This effectively would be similar to gtk3 and take a lot of time. After some initial rewrites, life changed and my time became limited. At the same time I heard rumors about a start of a gtk3 interface. So the interest of changing gtk2 dropped.

[Lazarus] Problem with Record Helpers and Identifier completion
Hi! in the past I have not used Lazarus that much, currently I am developing some code for embedded platforms based on fpc and I would like to make this code as usable as possible in Lazarus. I am currently extending the record definitions for embedded controllers with Record Helpers. (The reason is that this approach uses less precious flash storage than objects or classes and it looks cleaner to me than to redefine the records again). Problem with this approach seems to be that identifier completion does not have a clue about the extra procedures defined in the Record Helper. Here's an example: In stm32f10x_cl I have this code type TGPIO_Registers = record CRL : longword; CRH : longword; end; Then I have a helper Unit defining some extra procedures: unit gpioHelper; uses stm32f10x_cl; // necessary to make indentifier completion work at all type TGPIO_RegistersHelper = record helper for TGPIO_Registers procedure setConfig(bit : TGPIO_Bit; config : TGPIO_Config); procedure setConfig(bit : TGPIO_BitSet; config : TGPIO_Config); end; In main Code I now have: program test; uses gpioHelper; begin GPIOD. end. and hit Ctrl-Space after GPIOD. The record elements show up in completion, all the procedures defined in the helper class are not visible. Is it me doing something wrong? Or is there something that I can do with my code to create hints/whatever so that the helper classes are visible? Or am I doomed and should bite in the sour apple and redefine all records that I need?

Re: [Lazarus] Alpha transparency on GTK2 widgetset
Yeah, the proper approach would be to make a Cairo-based gtk2devicecontext implementation and it might still be a valid goal, depending on how long the gtk3 interface will be in development (after all it took years for the gtk2 interface to become the default in Linux). Also i think that with gtk2 and gtk3 being incompatible, we'll see gtk2 to remain around for a while, especially in non-GNOME-based desktop environments (such as MATE, the GNOME2 fork, XFCE, etc). But for the short term, this solves some common issues. Some of the stuff mentioned in the related bugs seem to require a more solid conversion to Cairo since currently there is a lot of information lost with the conversions between pixmaps and pixbufs.

For now i'm looking into trying to use the pixbuf when an image operation is requested and see if that helps for solving the most glaring issues with toolbars having no transparency and converting between tbitmap to tlazintfimage and back losing the alpha channel. It wont solve the issue of other operations (f.e. drawing a line, arc, rectangle, etc over an image with alpha channel), but that would require a complete rewrite of the GTK2 graphics context code to use Cairo (which will be necessary for GTK3 anyway). A patch for GTK2 bindings would surely be welcome. Do you know that GTK3 bindings also exist. They have a different architecture than GTK2 bindings. Zeljan has started them but they are in alpha state now. Contributions are welcome there, too.

Squeak is a Smalltalk system and all the changes are versioned automatically in the live image and shared via the Monticello repository. If they use svn it is probably some ancillary systems related to the project. Between 1st and 5 Jan their repository system has recorded 25 commits to about 10 different packages. Anyway I am not comparing a dynamic, interpreted system using a live image with a static compiled language as they are quite different paradigms and the development styles are quite different. -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

In other words, if I want working in something in Bugtracker -- to send a patch on the future -- how I can know if someone is working on the same bug? One can't tell for sure, but often you can tell by checking whether the bug is assigned to someone. This can be a wrong indicator however as - mostly in the Lazarus project - some bug categories are automatically assigned to people also one might accidentaly collect a bug by setting it to feedback and forgetting to unassign oneself. Nevertheless it's the best indicator you have. To be really sure you should maybe ask on the mailing list whether someone is working on a specific bug. Ok Sven, thanks.

True, new features are not being debated much but they are being developed surely. This is not only about fixing bugs. This is possible because people mostly agree that those features are needed. At least currently developers are not pulling to different directions. @Juha - Perhaps you could follow the example of the older wiser heads such as Florian and Matthias who have responded to this thread with examples and suggestions because they had a better understanding of why I asked this question. Just because someone's manners or style rubs you the wrong way doesn't mean they are trolling - which is generally understood to be creating drama and controversy for its own sake. I try to be more constructive. The fact still is that most features are in developers' personal ToDo--lists and not discussed actively by developers. However there are many ideas which get often discussed in forum and mailing list by many people. So there is no lack of discussion. There is only lack of people implementing the ideas. You forgot the most important means of communication which is the code commit history. We are like aliens using an alien language, Pascal in this case. It is the most powerful way to communicate SW, a human language cannot do it as well. Good program code explains to people what we want the computer to do.

[Lazarus] how about a HasProperty() property?
For example, if you want to loop though components and set the dbNavigator's DataSource property to that of the component if it has a DataSource property (and of course is not a dbNavigator itself). It seems you can't do that by using the component's hierarchy. Is there someway else to do that? Components do seem to have HasHelp and HasParent properties already. Perhaps being able to test for the Palate that the component is on would work, is there a way to do that? Thanks. A.

Unit typinfo contains: Function IsPublishedProp(Instance: TObject; const PropName: string): Boolean; Function IsPublishedProp(AClass: TClass; const PropName: string): Boolean; That should do what you want.
