Self.ControlByName('v' + IntToStr(i)).Hint := 'AAAAA';
i := i +1

Does not recognize ControByName
Help me

thanks

Define: USE_NAMES
Use: TObj.Name

> USE_NAMES - to use property Name with any TObj.
> This makes also available method TObj.FindObj( name ): PObj.

I'm making an application for WinCE.
I use lazarus 9.28.2 for Windows, and Kol-CE 2.80.3
I have a form with about 20 items TKOLLabel.
I need to run this code

per i: = 0 count-1 do
begin
Self.ControlByName ( 'v' + IntToStr (i)).Hint : = 'AAAAA'; //Self is the form
i: = i +1
end;

When completed (target = arm wince widget = SO = WinCE compiler = ppcrossarm)
Error: identifier idents no member "ControByName"
This code without using KOLCE work, so I would know how to convert it to use KOLCE

Maybe you didn't understand my previous reply.
Go to project options and define a new conditional of USE NAMES
Here is a test using KOL only (not the MCK):

program Test;

uses KOL;

type
PForm1 = ^TForm1;
TForm1 = object(TObj)

public
procedure ButtonClick(Sender: PObj);
end;

var
Form1: PForm1;

procedure NewForm1(var Result: PForm1; AParent: PControl);
begin
New(Result,Create);
with Result^ do
begin
Form := NewForm(AParent,'Test');

end;
end;

procedure TForm1.ButtonClick(Sender: PObj);
var

begin
for i := 1 to 20 do
begin

if c <> nil then
PControl(c).Text := 'zzz';
end;
c.Free;
end;

begin
Applet := NewApplet('Test');
NewForm1(Form1,Applet);
Run(Applet);

I designed the GUI using the controls of the bar KOL.
As I understand I should not use the controls at design time, but
create them at runtime?

Use of controls at design time is not possible in my case?

thanks a lot for the time you've spent.

<Цитата>
Jon © (05.01.10 18:03) [6]

You can use design time creation, that is not a problem.
Download this MCK project: http://www.sendspace.com/file/el3izp
Let me know if it makes sense to you.

Go to project options and define a new conditional of USE NAMES

In project options where insert USE NAMES?

sorry my bad english

<Цитата>
Дмитрий К © (05.01.10 21:03) [10]

In Lazarus Project - Compiler options... - Other - Custom options
Add -dUSE_NAMES

<Цитата>
magi6162 © (08.01.10 10:55) [11]

I did as you have written, but:

fmain_1.inc(19,17) Error: identifier idents no member "SetName"

thanks for all the help

<Цитата>
Jon © (08.01.10 14:41) [12]

Looks like a bug with Lazarus. In Lazarus IDE do this:
- Menu: Package >> Open loaded package...
- Select: MirrorKOLPackage >> Open...
- Click Compiler Options >> Other
- In Custom options add: -dUSE_NAMES
- Click OK
- Click Compile
- When compile completed, close package window and try again

Ok!!! great!!!

Now...

v1..vxx: TKOLLabel

for i := 1 to nMesi do
begin
c := Form.FindObj('v' + Int2Str(i)); <--- Error here
if c <> nil then
PControl(c).Hint :='zzz'
end;

fmain.pas(213,19) Error: identifier idents no member "hint"

"Hint" the property I need to store string data relating to the control.

thanks

You need to add another conditional define: USE_MHTOOLTIP

So now you will have: -dUSE_NAMES -dUSE_MHTOOLTIP

Then rebuild. The correct syntax for tooltips is Hint.Text:

procedure TForm1.Button1Click(Sender: PObj);
var
i: Integer;
c: PObj;
begin
for i := 1 to 20 do
begin
c := Form.FindObj('Label'+Int2Str(i));
if c <> nil then
PControl(c).Hint.Text := 'Label'+Int2Str(i);
end;
MsgOK('Label hints added!');
end;

MirrorKOLPackage when compiling with-dUSE_MHTOOLTIP, error:

C:\lazarus\components\kol-ce-2.80.3\kol\KOLMHToolTip.pas(268,50) Error: Identifier not found "TTM_GETDELAYTIME"

<Цитата>
Jon © (08.01.10 17:00) [16]

TTM_GETDELAYTIME is defined in delphicommctrl.inc

TTM_GETDELAYTIME = WM_USER + 21;

but in KOL.PAS it is only enabled for Win32...

{$IFDEF WIN}
//{_#IF [DELPHI]}
{$IFDEF WIN32}
{$INCLUDE delphicommctrl.inc}
{$IFDEF UNICODE_CTRLS}
{$DEFINE interface_part} {$I KOL_unicode.inc} {$UNDEF interface_part}
{$ELSE} // ANSI_CTRLS
{$ifndef FPC}
{$DEFINE interface_part} {$I KOL_ansi.inc} {$UNDEF interface_part}
{$endif FPC}
{$ENDIF UNICODE_CTRLS}
{$ENDIF WIN32}
//{_#ENDIF}
{$ENDIF WIN}

Try to add the relevant bits from delphicommctrl.inc to your unit.

Hopefully Yury Sidorov (the maintainer of KOL-CE) will read this and fix it in the SVN.

sorry,
My last message was wrong, MirrorKOLPackage compiling with -dUSE_MHTOOLTIP OK.

v1..vxx: TKOLLabel

for i := 1 to nMesi do
begin
c := Form.FindObj('v' + Int2Str(i));
if c <> nil then
PControl(c).Hint.Text :='zzz' <--- Error here
end;

still error:

fmain.pas(213,19) Error: identifier idents no member "Hint"

thanks
