TButtonColor

Post by fjrohlf » Tue Nov 17, 2015 5:17 pm

Is there some documentation or a good example of the use of the TButtonColor component? I have not been able to find much information.

Thanks,

Hello,

The documentation says:
TButtonColor wrote:Description
This Button control is internally used at Chart Editor dialogs.

It's like a normal TButton control, but includes a property to "link" this button to a Color property.

The Color is used to display a graphical filled rectangle at the right side of the button.
Clicking the button will automatically show the Color editor dialog to change the color.

Example:

Code: Select all

ButtonPen1.LinkProperty( Series1, 'SeriesColor' );
Here you have another example with two:

Code: Select all

uses Series;

var Series1: TLineSeries;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;

  Series1:=Chart1.AddSeries(TLineSeries) as TLineSeries;

  Series1.FillSampleValues();
  Series1.Pointer.Visible:=true;
  Series1.Pointer.Color:=Series1.Color;

  ButtonColor1.LinkProperty(Series1, 'SeriesColor');
  ButtonColor2.LinkProperty(Series1.Pointer.Brush, 'Color');
end;

So one does not have to enter any code for the button's onclick event? I would not have guessed that. Thanks again for your help.

Hi,

Exactly. You just have to link a TColor property to it.

That works very well - but how does one set the initial color of the "symbol"? Initially it is black and it does change once one clicks on it and selects a color but I would like it to start with a specified color (i.e., the existing color of a series).

The code I posted above does it for me here. Doesn't for you?
Can you arrange a simple example project we can run as-is to reproduce the problem here?

Thanks in advance.

see attached. Unfortunately, It uses some components from TMS but you should be able to see my buttoncolor code.

After cleaning any 3rd party reference I made the simplified example to work with this code:

Code: Select all

procedure TForm2.FormCreate(Sender: TObject);
var
  i: integer;
  Series1: TpointSeries;
  seriesarray: array [1 .. 3] of TpointSeries;
  buttonsarray: array [1 .. 3] of TButtonColor;
  ButtonColori: TButtonColor;
begin
  Chart1.View3D := false;
  Chart1.Legend.Visible := false;
  for i := 1 to 3 do begin
    Series1 := Chart1.AddSeries(TpointSeries) as TpointSeries;
    seriesarray[i] := Series1;
    Series1.FillSampleValues();
    ButtonColori := TButtonColor.Create(self);
    buttonsarray[i] := ButtonColori;
    buttonsarray[i].Parent := Self;
    buttonsarray[i].Left := 15;
    buttonsarray[i].Top := buttonsarray[i].Height * i + 15;
    buttonsarray[i].Caption := IntToStr(i) + '   ';
    buttonsarray[i].SymbolWidth := 30;
    buttonsarray[i].LinkProperty(Series1,'SeriesColor');
  end;
end;

ok, that does work. It even works when I restore the parent as the newly created TAdvTabSheet. Thanks!

One last thing - how can i set the initial colors for the button and the series? If I use code such as
Series1.Pointer.Color := clRed;
then the series has that initial color but the button does not (they have the colors that the series would have had without the change given above). I believe the answer to this will reveal what the problem was in my original code.

Hello,

Using a TPointSeries you should change the series color, not the pointer color:

Code: Select all

  Series1.Color := clRed;
Here the complete code that works fine for me:

Code: Select all

procedure TForm2.FormCreate(Sender: TObject);
var
  i: integer;
  Series1: TpointSeries;
  seriesarray: array [1 .. 3] of TpointSeries;
  buttonsarray: array [1 .. 3] of TButtonColor;
  ButtonColori: TButtonColor;
begin
  Chart1.View3D := false;
  Chart1.Legend.Visible := false;
  for i := 1 to 3 do begin
    Series1 := Chart1.AddSeries(TpointSeries) as TpointSeries;
    seriesarray[i] := Series1;
    Series1.FillSampleValues();
    ButtonColori := TButtonColor.Create(self);
    buttonsarray[i] := ButtonColori;
    buttonsarray[i].Parent := Self;
    buttonsarray[i].Left := 15;
    buttonsarray[i].Top := buttonsarray[i].Height*i + 5;
    buttonsarray[i].Caption := IntToStr(i) + '   ';
    buttonsarray[i].SymbolWidth := 30;
    ButtonColori.LinkProperty(Series1,'SeriesColor');
  end;

  Series1.Color := clRed;
end;
