QT-Gauge-Widget

Custom Gauge Widget for Qt QWidget and QMainWindow

A graphical gauge for qt/c++ applications

This gauge doesn't use any static picture or wallpaper, rather it is rendered at C++ Runtime by 'drawing'. This allows for dynamic changes to the instrument's attributes.

Extensibile widget can be adapted for use as Compass , Altimeter , etc...

How to use this widget:

• First use header and source file in your project
• Instantiate QcGaugeWidget object (this will run necessary initialization)
• Set key attributes for your application
• Add widget to layout (unless widget is already present in UI form)
• See example below:

Add to header (.h) file:

 #include "qcgaugewidget.h"
 QcGaugeWidget * mSpeedGauge;

Suggested initialization in .cpp file (change colours, units etc. as desired)

    mSpeedGauge = new QcGaugeWidget();          // Instantiate and call constructor    
    mSpeedGauge->setColour(Qt::cyan);           // Set accent colours        
    mSpeedGauge->titleLabel->setText("km/h");   // Title or Units
    mSpeedGauge->needle->setValueRange(0,80);   // Displayable range of values
    ui->verticalLayout->addWidget(mSpeedGauge); // Add widget to layout

Results in:

Can also be adapted for other uses:

This is building on other's work to make the widget more accessible and extensible.
