Correct me if I am wrong.

Now I know that TWn32WSCustomX classes are linked at runtime to TWSCustomX class procedures and functions, which are empty.

My problem is that one of these functions does not result, I don't know why. (I have already written some procedures that return, but now one of these fails). Any idea?

Thanks,
Ant?nio

The class name is TWin32WSCustomX and the problem is about a function which does not result. Any limit? Any restriction?

Do you mean the TWSCustomX.AMethod is called, but your TWin32WSCustomX.AMethod is not called?

The control is TRichMemo. Hello Ant?nio

Need to be noted that RichMemo is not part of standard LCL but a separate package.
Thus it has its own set of "register" process.

See richmemofactory.pas. This is the place where the Widgetset-specific RichMemo implementation is registered with LCL-RichMemo class.

thanks,
Dmitry

Dear Dimitry,

I have the RichMemo Revision 3703 version and I am trying to implement some extra features. I have made this for 2 ou 3 methods, but now I have a method which does not respond. I don't know why this occurs and if you could clarify this I would appreciate.

So what the hell do class procedure TCustomRichMemo.WSRegisterClass? It associates the LCL TCustomRichMemo with a certain WS-handler class.

That's necessary at the time TRichMemo is allocated by LCL it would receive a proper WS-level handler associated.
If there's no WS-specific handler registered/implemented, then TRichMemo would still be allocated by won't do have any RichMemo specific functionality.
As an example Qt widgetset doesn't have any implementation of RichMemo handles. However, an application using RichMemp could still be allocated.

Please note that WSRegisterClass is necessary for controls that heavily depend on the underlying widgetset. Pure cross-platform controls don't need this kind of bindings.

Dmitry

I can only guess that the changes you're talking about were reported here: http://bugs.freepascal.org/view.php?id=27009

From the changes I can see noted there, they're done not quite accurate

manner.
For example, Windows specific code is moved to TWSCustomRichMemo class (WSRichMemo.pas).

However, for the Win-widgetset the code should be added to TWin32WSCustomRichMemo (win32richmemo.pas)
Since TWin32WSCustomRichMemo drives RichMemo for Windows . TWSCustomRichMemo is only used for "unsupported" widgetset (such as Qt) or projected widgetsets (such as Cocoa)

thanks,
Dmitry

Forget what I wrote on that bugreport. Now I have added to TWin32WSCustomRichMemo.

class function TWin32WSCustomRichMemo.GetColor(const AWinControl:
TWinControl) :TColor;
begin
  SayHello;   // this fails
end;

Windows RichEdit messages refer to selection, you don't need to refer to text range. Windows specific implementation has no effect on the interface of RichMemo.

However, if there's a glitch in the Windows implementation please report it.

After clicking on the answer button, press <Down> twice (which selects the ellipsis) then press <Enter> and voil?, you get the message contents, which you can edit as you like.

But I agree GMail makes this unnecessarily complicated.

(the below is to Ant?nio actually but replied to Frederic to keep OT janitor duty to minimum)

Please also don't top-post if you don't have to.
(are you using a screen reader ? that would be just about only acceptable exception)

We are not commercial support operatives, we might not be 'on top of things' all the time.

Also this is a mailing list (though readable through a news server too) not a web forum with implicit threading.

/Not everybody/ has threading enabled or even available in their email/newsgroup readers /all/ the time.

Sometimes servers also mangle messages and the threading is lost, loosing context.

We need to see the message context and the natural reading sequence is down, not up.

Hence recommended place to put replies is UNDER the message, not above.

The linking exception is to allow to use the LCL in a non (L)GPL application. Without it you can still use it in (L)GPL applications. For example the IDE.

See also http://bugs.freepascal.org/view.php?id=23383 where at that time certain parts of the code were marked GPL.

Sorry, see by yourself: http://wiki.freepascal.org/lzRichEdit#License

As I posted on the forum:
http://forum.lazarus.freepascal.org/index.php/topic,26425.0.html

lzrichedit.zip does not mention license in readme or in doc folder. In the .lpk package, it mentions LGPL (so not "modified LGPL")

Apparently (I haven't checked) the pas files contain the modified LGPL license, so I suggested on the forum to harmonize the licenses so that they match the actual license.

Thanks,

According to the Wiki it only supports Linux/gtk2 and Windows/Win32. It is too early to add it to the LCL, isn't it?

"The two"? I don't really understand what you mean there. In fact, I have trouble understanding how this is a reply to my post. If neccesary, could you explain a bit more what you mean?

I refered to issues when using code with incompatible licenses. You yourself said to look at the lazrichtedit implementation. I'm qualifying that with the warning that incompatible licenses do not allow code reuse.

If you want to adjust paragraph attributes for the current selection only then you can subclass RichMemo (or CustomRichMemo) and add delphi RichEdit compatible properties, that would use existing RichMemo methods.
