[lazarus] Min/Max Constraint handling in Win32 interface
Hi, Where in the Win32-LCL interface does the Min/Max size constraints get set for Forms? I searched all the code and can only find information where it queries the size, but never sets the size. The Min/Max constraints do work for a TForm, but I can't seem to find out which Win32 API it calls to set those values. Any hints?

[lazarus] Object Inspector and non-default values
Hi, How does the Object Inspector detect non-default values of properties? For example: I create a custom component which has a Integer property defaulting to 100. The constructor also sets FMyProp = 100. TMyComponent = class(...) published property MyProp: Integer read FMyProp write SetMyProp default 100; end; If the value is set to something other than 100, it gets written to the .lfm file and the object inspector writes the value in Red. How does Object Inspector know that? Can you use RTTI to query such a property to detect a non-default value?

[lazarus] SQLdb : program crash using more than 9-10 fieldsets: bug...?
This is a bug notification... I managed to re-create the segmentation
fault bug.
The service was crashing without giving any output and any reason, the
problem was in the NUMBER of the parameters in the result set fetched in
the select:
10.
Fetching less parameters (9), all works. You can add and remove any kind
of parameter, not one in particular to force the crash.
The query is perfectly working both via ssh and graphical clients, even
on localhost.
A strange thing is that if I set parseSQL to true, I get a mysql syntax
error before the crash of the application:
Check the manual that corresponds to your MySQL server version for the
right syntax to use near 'GROUP BY i.pk_iscrizione, i.n_ingressi,
t.nome, a.nome, a.tipo_
So I'm guessing who parses the sql... if the mysql (as it should be) or
the component, cause there is no reason to have a sql syntax error from
a query that works perfectly via shell and gui.
As you can see from the query, there are no strange (italian) characters
in it.
I tryed also to concat two fields that I need concatenated in the code
(first name and last name (nome e cognome)) to make 9 fields fit me,
with no success.
So the problem seems to be not the number of parameters i fetch in the
query, but the number of parameters i fetch in the code via
sqlquery.fieldbyname('field').asstring
Also, a strange fact is that the crash happens the SECOND time I do the
query and not the first one... but I can also do it one time and then
crash the program with a second whathever query, so I suppose that the
first time I do the query the connection or the transaction are bugged
and the problem appear the second time I use them.
This is the crashing query, commenting any of the fields of the first
rows (so reducing the number (10) of the fetched fields) and commenting
the fetching I do in the second part of the code makes it work perfectly:
SqlQuery.SQL.Text := 'SELECT i.pk_iscrizione, i.n_ingressi, ' +

'a.nome as nome_attivita,

[lazarus] Custom editing of a TStringGrid cell (with PickList)
Hello,
I'm looking for ideas for making a TSringGrid behave exactly the way i like .
One of the columns ('Category') has a short list of pre-defined values , so
i've set the buttonStyle of that column to cbsPickList and defined a
select editor event handler:
procedure TTrackTimeMainForm1.StringGrid1SelectEditor(Sender: TObject; aCol,
aRow: Integer; var Editor: TWinControl);
begin
case aCol of
0: {category}
begin
Editor:=PickListCategories;
end;
1,2,3:
Editor:=StringGrid1.EditorByStyle(cbsAuto);
end; {case}
end;
My problem with this approaches is that i need three clicks:
- one for selecting the cell
- one for getting into the editing mode
- one for clicking the small button that opens the pickList
This is horrible for the user, even if it's an application for my own use.
How could I display the list of possible values with just one click ?
I realize that it must be possible to use the grid's OnClick , but maybe
there is some better/simpler solution that I'm not aware of .
PS: i'm on Linux using the fpc 2.0.4 , latest svn Lazarus and the gtk
interface.
Cheers,
Adrian Maier
