Both xorg-x11-6.8.2-37.FC4.49.2 and X-Win32 8.0.2216 (also xorg based)
have this problem.

You can check this by looking at the result for:
  XKeyCodeToKeysym(Display, N, M);

where N=10..20 and M=2..3

M=2,3 are the values of the 2nd keysym group and they result in 0, where
they (obviously) shouldn't be 0 if you look at the result of xmodmap

Example how to sort a TTreeView

First of all happy new year,

Can anybody show me how to sort a TTreeview? I am trying with the 
Customsort method but I don´t know how to call the right parameters.

|TTreeView.CustomSort(SortProc: TTreeNodeCompare): Boolean;| 
<http://www.lazarus.freepascal.org/lcl_doc/TCustomTreeView.html#link2668>

Could you show me a little example of how to declare the SortProc 
Variable of type TTreeNodeCompare?

Thank you for your help,
Alex

Re: Example how to sort a TTreeView

Thank you,

But almost I am really confused, that example is for Delphi, the 
TTreeView implementation of Lazarus is a little bit different, the 
number of parameters and declaration of CustomSort are different.
I just try with the example of the webpage and I get a compiler error:
Error: Incompatible type for arg no. 1: Got "<address of 
function(TTreeNode, TTreeNode, LongInt):LongInt;StdCall>", expected 
"<procedure variable type of function(TTreeNode, TTreeNode):LongInt of 
object;Register>"

Thank you for your help.

Naturally it's a matter of taste, but I really cannot get used to the 
indenting of begin-end. It just looks wierd to me, even after all these 
years.

It's something like

for (int x = 0; x < 99; x++)
  {
     FooStuff();
  }

Doesn't that look odd, too?

No, why? I always do that.

I don't know, it just always looks odd to me. I prefer

for (..)
{
}

or even

for (...) {
}

which, imho, only looks good in C.

Then again, there are probably even more coding styles in Pascal than in C.

This is exactly the way that I format those blocks in C#!

[lcl internals] - keyboard handling

Hi,
even looking at sources of various interfaces, I cannot really understand 
how the interface should behave in respect to lcl when handling keyboard 
events.

Let's look at keydown case:

(note: for "event considered handled" I mean the interface should tell 
native widgetset that the event has been handled, that is, widgetset doesn't 
handle/propagate further that message)

a key has been pressed.
Interface sends a CN_(SYS)KEYDOWN message
  If lcl handles it (result<>0), interface should consider the event handled 
and stop there
  (no xx_char or utf8keypress). right?
  if lcl doesn't handle it, interface should proceed:
    if key was changed it has to stop. right? the event has to be considered 
handled?

Does the interface have to send a LM_(SYS)KEYDOWN message then? does it have 
to do the same checks it did for CN_KEYDOWN (handled by lcl/key changed 
etc)?

If the key is not "special" (like arrows, ins, canc, return, backspace and 
so on) interface
sends an utf8 char via IntUTF8KeyPress.
  if lcl handles it (result=true) interface should consider the event 
handled and stop
  there (no xx_char). right?
