Speedometer and Gauge for Qt QWidget and QMainWindows

This is a graphical gauage for qt/c++ application you can use it in your application easily

In This gauge we don't use any picture or wallpaper , we making it on C++ Runtime by drawing

I just Show How to Create Gauge by this class But you can make other thing like Compass , AttitudeMeter , ...

How To use This gauge

First use header and source file in your project
After That add vertical layout to your ui file
In the End Use This code To Start

Add This to header (.h) file

 #include "qcgaugewidget.h"
 QcGaugeWidget * mSpeedGauge;
 QcNeedleItem *mSpeedNeedle;

Add This to Source (.cpp) file

    mSpeedGauge = new QcGaugeWidget;
    mSpeedGauge->addBackground(99);
    //this will add side color to gauge
    QcBackgroundItem *bkg1 = mSpeedGauge->addBackground(92);
    bkg1->clearrColors();
    bkg1->addColor(0.1,Qt::black);
    bkg1->addColor(1.0,Qt::white);
    QcBackgroundItem *bkg2 = mSpeedGauge->addBackground(88);
    bkg2->clearrColors();
    //this two line below will set background color of gauge
    bkg2->addColor(0.1,Qt::gray);
    bkg2->addColor(1.0,Qt::darkGray);
    mSpeedGauge->addArc(55);
    mSpeedGauge->addDegrees(65)->setValueRange(0,120);
    //this will add color red-green color band
    mSpeedGauge->addColorBand(50);
    // add value rage
    mSpeedGauge->addValues(80)->setValueRange(0, 80);
    //set gauge title
    mSpeedGauge->addLabel(70)->setText("Km/h");
    QcLabelItem *lab = mSpeedGauge->addLabel(40);
    lab->setText("0");
    mSpeedNeedle = mSpeedGauge->addNeedle(60);
    //add lable 
    mSpeedNeedle->setLabel(lab);
    // set needle color 
    mSpeedNeedle->setColor(Qt::white);
    //add range for your gauge => it should be just like the gauge range 
    mSpeedNeedle->setValueRange(0,80);
    mSpeedGauge->addBackground(7);
    //add some shadow like glass
    mSpeedGauge->addGlass(88);
    //add this to your vertical layout
    ui->verticalLayout->addWidget(mSpeedGauge);
