Problem with Gauge component.

[Rrodd 0]

Hello, I have a problem with the component Gauge, looks like it draws the text twice, one white and another with the inverted color (this is the only I want to be drawn), looking bad.

I am using a "Windows VCL Application - Delphi" under Delphi 10.4.

I'd like to know what to do for this to work like expected, or another free gauge alternative and similar component.

I have sent a snapshot of the problem.

 

Thanks.

TGauge is a really ancient sample component (from D1 days I think). Have you looked at TProgressbar as alternative?

Hi, TProgressbar has a graphical animation and does not add a percent, and I don't know how to have this features with it, and remove the animation.

The Bonus KSVC components included with Delphi but not installed by default include some components that might help. Installable through GetIt.

 

Going through a few it seems the Meter component from the KSVC components can come closest.  The KSVC progress bar makes the text match the bar or background color depending on the progress which makes the yellow bar / white background combination a problem. Also here I don't see the messed up text for the ancient TGauge.

Overdraw the control.    Here's two workarounds. The second uses the centering text of Panel.caption. 

 

 

procedure ComputeBarCenter(control: TControl; var x, y : Integer);
begin
  with Control do begin
    x := Left + width div 2;
    y := Top + Height div 2;
  end;
  //self.Left := 10;
end;


procedure TForm9.Button1Click(Sender: TObject);
var
  textX, textY: Integer;
begin
  gauge1.ShowText := False;
  computeBarcenter(gauge1, textX, textY);
  self.Canvas.TextOut(textX-5,textY-3,'50%');
end;

procedure PutlabelControlAroundGraphic(panel, graphic: TControl);
begin
  with graphic do
  panel.SetBounds(Left-3, Top-3, Width+3, Height+3);
end;

procedure TForm9.Button2Click(Sender: TObject);
begin
  Gauge2.ShowText := False;
  panel1.Caption := 'Working hard Boss';
  PutLabelControlAroundGraphic(panel1, Gauge2);
end;
