Re: [Interest] Force QPainter color draw for SVG files?

[mat //common mail]

Another solution (without resource files):

#ifndef SVGICONS_H
#define SVGICONS_H

#include <QObject>
#include <QPixmap>
#include <QIcon>
#include <QtSvg>

class SvgIcons
{
private:
  static QString GeneralSvgPart();
  static QPixmap GeneratePixmap(int width, int height, QString
*lastSvgPart);

public:
  //FileToolBar
  static QIcon Icon_Close(int width, int height, QColor color);
  static QIcon Icon_PrintPreview(int width, int height, QColor color);
  static QIcon Icon_Print(int width, int height, QColor color);
  ...
  //HelpToolBar
  static QIcon Icon_Help(int width, int height, QColor color);
  static QIcon Icon_Info(int width, int height, QColor color);
  ...
};

#endif // SVGICONS_H
