Hi,

here is a very basic thing.
I want to use a double click event, but I cannot get it fired:

For reproduce

create a new project
add a Tchart
add a TchartEditorPanel
write a doubleClickEvent for TChartEditorPanel

=> start the program, double click the panel
here: nothing happens
The same with the click event.

this time it is very easy to add a sample code:

the code:

Code: Select all

unit Unit7;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, VclTee.TeeGDIPlus, VCLTee.TeeEdit,
  VCLTee.TeEngine, Vcl.ExtCtrls, VCLTee.TeeProcs, VCLTee.Chart;

type
  TForm7 = class(TForm)
    Chart1: TChart;
    ChartEditorPanel1: TChartEditorPanel;
    procedure ChartEditorPanel1DblClick(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form7: TForm7;

implementation

{$R *.dfm}

procedure TForm7.ChartEditorPanel1DblClick(Sender: TObject);
begin
  ShowMessage('Why ist this event not fired on double click?');
end;

end.

=================================
the form:

Code: Select all

object Form7: TForm7
  Left = 0
  Top = 0
  Caption = 'Form7'
  ClientHeight = 674
  ClientWidth = 820

Hello Cheryll,

I could reproduce this so I've added it to the public tracker:
http://bugs.teechart.net/show_bug.cgi?id=903

Hi,

thank you for doing so.

What would you recommend as a workaorund?
I use this doubleclidk as "smart clean up" for my panels.
It works like this:
My panels have associated buttons.

OnClick the button happens:
"myPanel".Visible:=true;

Doubleclicking the panels does:
"myPanel".Visible:=false;
and "shrinks" the panel to the button again.

I did not program many panels with this idea.
So it would not be a miracle to change all or them to a different event, which would work with ChartEditorPanel as well.
But which one? Double click is that nice to clean the desktop.

Regards,
Cheryll

Hi Cheryll,

I'm afraid I can't think on any workaround at the moment.
I'll increment the ticket priority.
I'd suggest you to add you mail to the CC list on the ticket so you can be notified when an update arrives.

Hi Jeray,

thank you for your answer.

I use TeeChart2013 Pro without source code and my support ID will expire within a few days.
Will there be an update for me?
And if yes, when about?

How do I add this thing you suggested? I have not understood where I can add what.
Would be great to receive just an update information. But to get one mail a week, would be too much, because the one-mail-a-week summed up dramatically in the meanwhile.

Regards,
Cheryll

I'm afraid I can't tell you if this is going to be fixed before your subscription expiration.
I'd suggest you to subscribe to the ticket on the public tracker to be automatically notified when an update arrives. And when you'll know this has been fixed in our internal sources, you'll be free to ask us if we have plans for a maintenance release and what options you have to get that fix.
If at that time your subscription has expired, we may be able to tell you a workaround.

In the ticket on the public tracker, you'll find the CC list on the top right section (you need to be registered on the system to see this option):

This system doesn't send spam, just a mail with the information detailing the modifications the according ticket has suffered.

Hi Yeray,

thank you for your reply.

This may be the reason, why I did not manage it:
There is no box reading "cc" for me. Probably this is, because I am not logged in. I must not edit anything.
Unfortunately I do not have the permission to this site. The password from here is not accepted.

Is there an alternative way to add my name?

Thanks,
Cheryll

Hi Yeray,

thank you for your reply.
Unfortunately it did not work.
I retried several times, allowed cookies, asked for a password reset.
Did not work.

I keep reading:
"Die Kombination aus Benutzername und Passwort ist ungültig. "
(=the combination of user name and password is not valid)

My user name is Cheryll as well, the chosen secundary mail-address is used by the system to send tokens.
So the address is saved.

(btw: The password-resend-field asks to key in the "user name". To my mind, it expects "e-mail" instead.)

Cheryll
