During the package installation, recompiling should be triggered rather 
automatically. So I don't think it is a disadvantage.

Re: [Lazarus] TTreeView, string and SIGSEGV

2013-08-26 Thread Xiangrong Fang 
Ok, that's reasonable, however:

1) If I use Move() is there a "manual" way to increate the string ref count?

2) why the error is gone if I change this line:

prev := tv.Items.InsertObjectBehind(prev, p^.title, p);

to this:

prev := tv.Items.InsertObjectBehind(prev, 'Node #' + IntToStr(i), p);

3) Why this error does not happen on node #0 and #3, but only node #1 and
#2?

4) Why it behaves different on Windows and Linux?

Thanks!

Actually it is the other way round. The source editor does not remain
behind the package editor.

It works here. Please use at least svn revision 42501. 
Can you give more details about the mouse and keyboard commands you use
to open the package?

Yes, but it is better to let the compiler do the work:
p^:=PNode(tv.Selected.Data)^;

All this has the same answer:
When you mess up the heap you get results depending on the current
memory, which depends on lots of stuff. The results
can vary from host to host and might not even be the same on each run.
In other words: random.
Windows and Linux have different approaches how to initialize memory,
so you see differences more likely.

[Lazarus] SynEdit Development Status

2013-08-26 Thread Fabrício Srdic 
Hi,

I'm new to the Lazarus/Free Pascal.

I have posted this message on the lazarus forum, do not know if there
is the best
place to discuss this topic...

According to the wiki page, the SynEdit contained in Lazarus and used by
Lazaru's editor is based on SynEdit 1.03. The current version of the
orginal SynEdit is 2.07.

Wiki also says that there is a port of the version 2.05 to Lazarus and also
says that there is a attempt to redesign the component.

My questions:

What are the future plans of the Lazaru's dev team for the SynEdit?

Is the team planning to use the port of the version 2.05?

Is the project to redesign the component a fork of the original SynEdit
project, breaking the compatibility between both components in the future
versions or the redesign will occur in the original project?

Best regards,
Fabrício

Hi Malcolm,

I made a few testprograms that work fine with your code. Now I made a 
full keyboard (Belgian AZERTY) and I'm having a problem I can't solve.


The keyboard has some "special" characters : é§èçà and others. Those are 
not 1 byte characters. When I add them, they appear in the memo, but the 
next character seems to erase the memo. If I have already some lines in 
it, all disappears and the cursor is on the first line, fully left.

I add the characters with a string :

Kars:='§';
Memo1.Text := Copy(Memo1.Text, 1, testcaretpos) + Kars + 
Copy(Memo1.Text, testcaretpos+1, MaxInt);


Actually, I do this in a procedure with Kars as a parameter.

Any suggestions where to look ?

BTW, I tried this on Lazarus 1.0 on Linux.

Thanks,

Koenraad Lelong

Basically, these options tell the component to automatically resize the
Column 1 to fill the remaining header space (control width - width all
other columns)

Re: [Lazarus] SynEdit Development Status

2013-08-26 Thread Fabrício Srdic 
Thanks for the reply!

My name is Fabrício, i am a certified delphi programmer. I'm using Delphi
for over the last five years.

I'm Brazilian (thus, sorry if my English speaking is not good =)).

I'm would like to use Lazarus to build my own projects and i would like to
contribute to the community too.

I'm new to the Linux platform, but i'm still using Windows in my work.

I have noticed that doesn't exists a powerfull text editor - like Notepad++
- which I could use the same editor on both Windows and Linux.

I still prefer a text editors like Notepad++ - so, Gnu Emacs and Vi doesn't
work for me.

In Linux we have KEdit, but it's not avaliable on Windows platform. JEdit
is powerfull but it's Java-based, thus launches slowly...GEdit has fewer
features than the others.

So, initially, I'm planning to join the existing LazEdit project and help
to improve it. This also may be an opportunity for me to contribute to the
Lazarus project, learning about the SynEdit and helping to maintain this
component that is part of the Lazarus IDE today.

Regards

Thanks a lot for the 1.0.12 release. I noticed this minor glitch: The tar.gz 
archive in 
http://sourceforge.net/projects/lazarus/files/Lazarus%20Zip%20_%20GZip/Lazarus%201.0.12/
 has at least a wrong name. I did not check the content.
