Re: [lazarus] Lazarus programs with multiple languages?
Adilson, ResourceStrings are exactly meant for that purpose. Read more on them in the FPC documentation. If you want a working example check the idetranslations.pas file in lazarus/ide. The nice thing is that lazarus reads it's translations directly from .PO, so you don't need to compile to .MO. In the lazarus directory there's a localize.bat file that converts the .rst files (generated by the compiler) to .PO files. Darius -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi guys. I've been away from Lazarus and Pascal for a very long time and I want to return to my favorite language, even if just for fun :) I'm thinking about create a test application and I was wondering if there is internal support to have texts in multiple languages.

[lazarus] lazarus licensing
Hi, I'm having some questions about the licensing of Lazarus. According to the docs supplied lazarus sourcecode is GPLed. Does this mean that the IDE binary is too? Is this automatically the case always? In my company I got the question to provide a proof that Lazarus is freeware. I cannot find it on the website. The only remark I found in the about section is that you can create commercial apps with the ide. I'm shure that other have similar issues, therefore I would like a legal issues section to be placed on the main site page? The attachment represents possible contents. What do you think? Darius This page answers most of the common queries relating to the Lazarus GPL license. Q1. What does the GPL mean and where can I find it? Q2. What does the Lazarus GPL license mean? Q3. What are the requirements to use Lazarus for internal use? Q4. Does the Lazarus GPL license prohibit commercial use? Q5. Is it possible to include the Lazarus software in CD's accompanying books? Q1. What does the GPL mean and where can I find it? GPL means General Public License and you can find it here: Q2. What does the Lazarus GPL license mean? Note: this answer gives you a short general explanation in common language of the meaning of Lazarus GPL license but keep in mind that only the license is legal. Lazarus GPL license allows you to: use freely Lazarus for non commercial use use freely Lazarus for commercial use if you do not use it as a derived software (ie a modified Lazarus) or a composite software (ie Lazarus included in another software). Lazarus GPL license forbids you to: use a composite or derived version of Lazarus for commercial uses without acknowledging Lazarus. Q3. What are the requirements to use Lazarus for internal use? There is no requirements for the use of Lazarus for internal use and Lazarus GPL license makes no distinction between public scientific and research area and industrial environment. Q4. Does the Lazarus GPL license prohibit commercial use? No, the Lazarus GPL license does not prohibit commercial use as long as you do not modify Lazarus software or include it in another software. Q5. Is it possible to include the Lazarus software in CD's accompanying books? Yes, it is. You can reproduce and distribute Lazarus software on any support as long as you do acknowledge the original Lazarus software.

[lazarus] TStringGrid Question
I am using a TStringGrid in a project that I am working on. I have a few questions about the use of this and all my delphi books seem to delve into DBGrids but not string grids. Here are my questions:1. My grid would allow the user to enter data in the first column while the other columns show result based on the data just entered. How do I selectively restrict data entry to a column/row/cell? 2. If the user presses enter while in a cell, the cell to the right of the previous one is selected. How do I change this so that the one below is active?3. What is the best event to use for updating a running total as the user enters data? In other words, the user has entered a number and gone to the next cell, I want to do a summation and present the new total. Thanks!Matt Henley

RE: FreeAndNil (was: RE: [lazarus] procedure TObject.Free)
Couldn't they have used a var Obj:TObject instead? Would there be a problem with passing nil objects to that proc then? I wonder why No, because the compiler requires an the 'var' parameter is of exact same type, it can't even be a descendant :-( It does indeed. Hadn't ever needed such a thing so didn't notice it. One could use a PObject param instead of a var instead, but then they'll have to use @ to pass an object to SafeFreeAndNil. Another interesting thing also, is that both x^.Free and x.Free work (the button disappears when SafeFreeAndNil gets called at the button's event handler), seems the Delphi compiler treats pointers to objects as the objects themselves or something like that. Of course x:=nil wouldn't also do the same as x^:=nil at the next line. type PObject=^TObject; procedure SafeFreeAndNil(x:PObject); begin x^.Free; //seems x.Free also works! x^:=nil; end; procedure TForm1.Button1Click(Sender: TObject); var x:TButton; begin x:=button1; SafeFreeAndNil(@x); x.Caption:='A'; end; The x.Caption:='A' doesn't throw a runtime error at Delphi7, which made me wonder why. So I added if x=nil then x.caption:='nil'; right after SafeFreeAndNil(@x) And it even hit the breakpoint and I stepped and executed the line x.caption:='nil' even though x was nil (cause of the if statement). Changing x^:=nil to x:=nil of course made it not hit that breakpoint I even noticed that with x^:=nil (which is the correct thing to have) for SafeFreeAndNil to do its job, if one adds a Label on the form, they get an EAbstractError with no more details after SafeFreeAndNil is called. Not sure why, most probably cause the event handler of Button1 kills Button1 and there's some problem with the stack then when the event handler returns or with message passing. This seems to bite only if there are more than one controls on the form. The following seems to work fine type PObject=^TObject; procedure SafeFreeAndNil(x:PObject); begin x^.Free; //seems x.Free also works! x^:=nil; end; procedure TForm1.Button1Click(Sender: TObject); var x:TLabel; begin x:=label1; SafeFreeAndNil(@x); button1.Caption:='A'; end; Although if I use x.Caption:='A' it doesn't throw an error (even though x is nil). Have to use the /cpu view I suppose to see what Delphi7 compiler generates there (it's not the first strange behaviour with borland's pascal compilers that I've seen over the years [using them since arround 1990]) As it is now it does very bad crash if you pass by accident say an interface reference to it instead of an object reference (can easily do this mistake if one reengineers their code to use interfaces - they may forget to remove the FreeAndNil stuff, thus getting bad runtime crashes instead of a compiler message that a TObject descendent is needed as param to FreeAndNil) Is FreePascal using TObject there or a var Obj param too? I've just checked (version 2.0.2) and it indeed is implemented like Delphi :-( But as a matter of fact it could have been implemented the right way, because FPC does the sane thing and allow descendants as 'var' parameters. Since object references are just pointers, I suppose FPC does correctly, so Lazarus could use the var:TObject version of FreeAndNil procedure FreeAndNil(var x:TObject); begin if xnil then x.Free; x:=nil; end; One might say you don't need to check for nil, Free must be checking it too, but not sure which is worse, an extra nil check or one unneeded call to Free (I suppose the 2nd is worse, although with Delphi passing params using registers by default instead of using the stack I'm not sure) Yerder yet there's a 'FreeThenNil' function in LCLProc which calls obj.Free before setting the pointer to null :-/ Why is there a FreeThenNil too apart from FreeAndNil. Is it supposed to do something different?. Not sure if the order there plays any role.

Re: [lazarus] lazarus licensing
Hi ! In my company I got the question to provide a proof that Lazarus is freeware. I cannot find it on the website. The only remark I found in the about section is that you can create commercial apps with the ide. All source files refer to the COPYING file. No other proof is needed ? . . . I'm shure that other have similar issues, therefore I would like a legal issues section to be placed on the main site page? I think it can be useful, but nor prioritary... Legal issues are a very important issues. Copyright on the source code could be faked, so ours employers can't trust them. An explicit License page in the Lazarus's site can't be faked. That way you can provide a very useful way to prove the legality of using Lazarus as a tool for software development. Gustavo Jiménez ps: How much will cost a paper with an explicit License agreement, signed by the Lazarus developers ? _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] lazarus licensing
Are some employers that paranoid? I mean.. go to the http://lazarus.freepascal.org website and click on About Lazarus... that page explains it pretty well... including the Can I develop commercial products with this? section. Just a little up the page, it says that the IDE is gpl. But copright in source pulled from the development site by your employer from cvs/svn is about as trustworthy as you are going to get. If needed they can pull up the development history.Copyright on the source code could be faked, so ours employers can't trust them.Our IT department loves GPL software.. they dont push it as a panacea but we have Dia, Gimp, Scribus and Firefox(gpl?) floating around.

Re: [lazarus] TStringGrid Question
- Original Message - From: Matt Henley To: lazarus@miraclec.com Sent: Friday, June 23, 2006 9:28 AM Subject: [lazarus] TStringGrid Question I am using a TStringGrid in a project that I am working on. I have a few questions about the use of this and all my delphi books seem to delve into DBGrids but not string grids. Here are my questions:1. My grid would allow the user to enter data in the first column while the other columns show result based on the data just entered. How do I selectively restrict data entry to a column/row/cell? 2. If the user presses enter while in a cell, the cell to the right of the previous one is selected. How do I change this so that the one below is active?3. What is the best event to use for updating a running total as the user enters data? In other words, the user has entered a number and gone to the next cell, I want to do a summation and present the new total. Thanks!Matt Henley 1. Create a OnSelectEditor event and set there: if Col1 then Editor:=nil; 2. in Object inspector set AutoAdvance:=aaDown 3. Create a OnEditingDone event there you can recalc the total. Note: OnEditingDone may be triggered some times at the grid setup after that is triggered when user ends editing. Jesus Reyes A.
