Overview
|
|
--------------------------------------------
|
|
A3nalogGauge - simple component for displaying
|
|
floating point value as analog voltmeter. In
|
|
addition to AnalogGauge component, the A3nalogGauge
|
|
allow to use the supersampling antialiasing algorithm
|
|
for improvement the image quality. Besides, the
|
|
A3nalogGauge contains additional properties for
|
|
more powerfull control of the own face. And also
|
|
others, less significant improvements.

Reference
|
|
--------------------------------------------
|
|
The component contains fallowing properties:
|
|
|
|
- these properties define the voltmeter elements colors:
|
|
* MinColor: TColor - color of indicator of minimum range;
|
|
* MidColor: TColor - color of indicator of normal range;
|
|
* MaxColor: TColor - color of indicator of maximum range;
|
|
* FaceColor: TColor - voltmeter scale background color;
|
|
* TicksColor: TColor - voltmeter scale mark lines color;
|
|
* ValueColor: TColor - color of values on mark lines;
|
|
* CaptionColor: TColor - values unit name color;
|
|
* ArrowColor: TColor - voltmeter pointer arrow color;
|
|
* MarginColor: TColor - margin rectangle color;
|
|
* CenterColor: TColor - color of a knob on an axis of the pointer arrow;
|
|
* CircleColor: TColor - color of circles on mark lines;
|
|
|
|
- these properties define the voltmeter elements sizes:
|
|
* CenterRadius: Integer - radius of a knob on an axis of the pointer arrow;
|
|
* CircleRadius: Integer - radius of circles on mark lines;
|
|
* Angle: Integer - the angle of scale segment;
|
|
* Margin: Integer - margin width;
|
|
* ArrowWidth: Integer - width of pointer arrow;
|
|
* LengthMainTicks: Integer - main (marked) tick lines length;
|
|
* LengthSubTicks: Integer - additional tick lines length;
|
|
* Style: TStyle read - the scale styles (left corner, on center and
|
|
right corner);
|
|
* NumberMainTicks: Integer - number of main tick lines;
|
|
* FaceOptions: TFaceOptions - defines what voltmeter elements will
|
|
be displayed;
|
|
|
|
* Position: Single read - the value for display;
|
|
* Scale: Integer - the maximal value for display (minimal is always 0);
|
|
* IndMaximum: Integer - maximal value for normal range;
|
|
* IndMinimum: Integer - minimal value for normal range;
|
|
* Caption: string - this text will be displayed in the voltmeter centre;
|
|
* AntiAliased: TAntialiased = (aaNone, aaBiline, aaTriline, aaQuadral) -
|
|
Mode of smoothing. Accordingly: without smoothing, smoothing with
|
|
cells of 2x2, 3x3 and 4x4 pixels;
|
|
* OnOverMax: TNotifyEvent - this event is fired if the value reached
|
|
the maximum of normal range;
|
|
* OnOverMin: TNotifyEvent - the same for a minimum;
|
|
|
|
- if you have set a "TICKER" condition, the component will calculate own
|
|
performance:
|
|
|
|
{$IFDEF TICKER}
|
|
* Frames: Integer - last repaint speed, frames per second (FPS);
|
|
* OnFrames: TNotifyEvent - this event will fired when performance value
|
|
has been changed;
|
|
{$ENDIF}
