Thanks for any advice Don't know what version do you have, some days ago a patch was submited that implements by default ascending sorting based on string comparision, previously all comparision returned 0, ie assume that all strings are equal, in this circustances the sort algorithm still swap some rows and that's why you may see funny jumping results after repeated sorting. But if you want custom sorting (descending) there are some alternatives; a. Create an handler for StringGrid's OnCompareCells event, something like this: procedure TForm1.StringGrid1CompareCells(Sender: TObject; Acol, ARow, Bcol, BRow: Integer; var Result: integer); begin // Compare strings result := CompareText(StringGrid1.Cells[ACol,ARow], StringGrid1.Cells[BCol,BRow]); // if you want to compare integers instead of // strings so '1','3','11' are correctly sorted: // result := StrToIntDef(StringGrid1.Cells[ACol,ARow],0)-StrToIntDef(StringGrid1.Cells[BCol,BRow], 0); // suppose that there is a checkbox that enables // descending sorting, do something like this if Checkbox1.checked then Result := -Result; end; b. Install SemaphorGrid (examples/grid_semaphor) afaik, it also implements sorting with several options. Jesus Reyes A. ___ Do You Yahoo!?

Re: [lazarus] Help with DLL (using pchar, etc.)
As an experiment for CompactSysUtils project I started a while ago, I have used this opportunity to demonstrate why FPC should reorganize the FPC sysutils unit for better smartlinking (i.e. create just one more unit than just sysutils to take care of smartlinking). Many functions in the FPC sysutils unit do not rely on any finalization or initialization code. By simple copy and pasting some of the sysutils functions into a unit of my own, called CompactSysUtils, I have gotten the DLL down to 40KB which was previously 91KB Project files showing 40KB DLL versus 91KB DLL is here: http://z505.com/pascal/MD5Hash/MD5Hash_COMPARE.zip CompactUtils and CompactSysUtils project is here: https://opensvn.csie.org/pspcgi/psp-lib-1.5.0-devel/src/extras/CompactUtils/ In order to compile the CompactUtils version in that zip file, you will need the latest copy of the compactutils.pas and compactsysutils.pas which is located on the SVN link above. Sometimes we don't worry so much about bloat like this since today's processors are getting faster, but this one is a no brainer. There is no work to be done other than copy/paste functions and reorganize them such as I have done with CompactSysUtils project. I have also made notes about this before on the mailing lists, such as mentioning how the findpart function can be cut copied and pasted right out of the StrUtils unit so that no sysutils initialization and finalization is hauled in. Maybe people can learn from this with the lazarus project too - as I'm guessing some (not all) the reason lazarus exe's are so big is because or simple initialization/finalization bloat. Sure there are abstraction bloat that is incurred for multi-platform programming in SOME CASES, but I've just proved with above CompactUtils project that abstraction has nothing to do with the majority of the bloat in this case. Rather simple reorganization in this case, to cut the EXE and DLL in half (actually, *more* than half). So either I continue to maintain this compactutils project with my elite cutting/copying/pasting skills or the FPC team decides to reorganize sysutils at the distribution level (i.e. kill the compactutils project and just do it in the RTL itself). Also anyone wishing to participate in this compactutils project I started is welcome - I started it to gain smartlinking knowledge myself and I'm sure others could benefit from knowing more about smartlinking. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
[lazarus] -dPassWin32MessagesToLCL and WndProc
Hello, This has being discussed before, but was non-conclusive. A conditional compile was added around code witch forwards all messages = WM_USER to the LCL (and thus WndProc) on Win32 Widgetset. I see many advantages on not having the conditional compile, but I can't see any advantages of having it. Thus I think Lazarus would be a better software without it. Advantages of not having the conditional compile: * Compatibility with Delphi * No need to recompile the LCL. This can take around 20 minutes on a very old 400 Mhz computer. * Does not affect multiplatform capabilities because windows will never send a message = WM_USER unless the programmer has created code witch tells windows to send such messages. Even if Windows starts sending messages for no reason, I still don't see how this would affect Linux code. Advantages of having the conditional compile: please, fill me. thanks a lot for your attention, Felipe _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Thank you very much for working at this spot.
I've applied it and it is not the whole thing (or too much of it):
- TButton and TPanel do not react to setting the color at all
I've investigate setting colors under GTK
SetColor for tButton and tBitBtn now work
In attach new patch and simple program to test
Please check, if it is good way to do this.

I was thinking of messages sent using the Windows API. What are other ways of sending custom messages? If the LCL implements a multiplatform message sending routine, supose I use it to send a = WM_USER multiplatform message. The messages gets locked in the win32 widgetset. Now I want to retrive that message on WndProc. Where is it? It doesn´t get there, because it was locked in the widgetset. What can the Widgetset do with that message? Nothing.

Therefore I will be happy with a define, at least a define to turn it off. IMHO the way to do what you want to do, i.e. to receive a wm_user or higher message on win32, is to hook a windowproc using OldWindowProc := Windows.SetWindowLong(MyForm.Handle, GWL_WNDPROC, MyWindowProc); with MyWindowProc declared as a function (not of object). Touching those wm_user messages in windowproc is a hack IMHO. Of course if you convince Micha, Marc and Mattias, I won't fight it anymore, although I don't want to have my name on that commit.

If the LCL implements a multiplatform message sending routine, supose I use it to send a = WM_USER multiplatform message. The messages gets locked in the win32 widgetset. Now I want to retrive that message on WndProc. Where is it? It doesn´t get there, because it was locked in the widgetset. What can the Widgetset do with that message? Nothing. If I understand it right, the WM_USER messages are not understood by the winapi. So, the only purpose of WM_USER messages is interprocess communication, isn't it? Michael VC has implement some platform independent IPC units.

That is what I was hinting on in my last sentence.
Touching those wm_user messages in windowproc is a hack IMHO.
Is using Windows API a hack?
No, by no means. The way you want to get at it is, IMHO.
You can find an example of necessary use of WM_USER message for
creating a taskbar icon on the MSDN website:
http://support.microsoft.com/default.aspx?scid=kb;en-us;149276
notice this part on that page:
Private Function setNOTIFYICONDATA(hWnd As Long, ID As Long, _
Flags As Long, CallbackMessage As Long, Icon As Long, _
Tip As String) As NOTIFYICONDATA
Dim nidTemp As NOTIFYICONDATA
nidTemp.cbSize = Len(nidTemp)
nidTemp.hWnd = hWnd
nidTemp.uID = ID
nidTemp.uFlags = Flags
nidTemp.uCallbackMessage = CallbackMessage // = WM_USER message!
nidTemp.hIcon = Icon
nidTemp.szTip = Tip Chr$(0)
setNOTIFYICONDATA = nidTemp
End Function
I am using this for callback messages from the Windows API.
This is OK.
I bet there are many other Windows API functions that need special
messages.
Yes, and you can receive them by hooking the windowproc.

Then there should be a win32 widgetset function:
TWin32Widgetset.AddCustomMessage
or something like that. This way it is clear, that the code is not portable.
I hope eventually someone volunteers to start a package with win32, gtk and
carbon tray icons.

Sounds a good solution. Much better then recompiling the LCL! I hope eventually someone volunteers to start a package with win32, gtk and carbon tray icons. I am already doing it =P It will probably be ready before February. For win32 and gtk at least. I don't have easy access to a Mac, but I already know somethings. The Mac tray icon system is imensely different from windows or linux, and this will be a problem.

RE: [lazarus] TIpHtmlPanel
Dear Jesus,
Thank you very much for your help.
I realized that I was seeking for answer at the wrong direction.
Following your instructions I managed to display html page loaded from
MemoryStream. I found that TIpHtmlPanel does not support Style Tags and
sometimes paints in a strange way. Is it just version's restrictions or
could I improve it's quality?
Are you located on Earth? :-)

Basically you can make it work in two ways, with a dataprovider and

Working samples for both aproaches are included in lazarus.
