Inheritance diagram for BarCode:

CanvasBarcode

List of all members.


Detailed Description

This class creates a QPixmap from a barcodeData struct. Several backends are supported to generate the pixmap. GNU Barcode pdf417_enc TBarcode (http://www.tec-it.com)

This tools generate a postscript file. The ps file is transformed to a PBM file scaled to the requested resolution or screen resolution using ghostscript.

The generated barcodes are cached using BarcodeCache. To fill a barcodeData struct with data from the user, you might want to use BarcodeWidget.

A small example, of how to generate a valid Barcode in your application without the use of BarcodeWidget:

  barcodeData data;
  BarCode::fillDefault( &data ); // setup a barcode object with valid data
  data.value = "KBARCODE";
  data.type = "code39";
  BarCode b( &data ); // create a barcode object
  QPixmap p = b.pixmap(); // get a pixmap of the barcode
