no match fo 'operator[]='

[jeff28]

I am trying to make my own SVGGenerator.
here is my displaywidget.h:

#ifndef DISPLAYWIDGET_H
#define DISPLAYWIDGET_H
 
#include <QHash>
#include <QWidget>
 
class DisplayWidget : public [qtclass]QWidget[/qtclass]
{
    Q_OBJECT
 
public:
    enum Shape { BStar = 0, RStar = 1 };
    enum Background { BBackground = 0, CBackground = 1, PBackground = 2 };
 
    DisplayWidget([qtclass]QWidget[/qtclass] *parent = 0);
    void paint([qtclass]QPainter[/qtclass] &painter);
 
public slots:
    void setBackground(Background background);
    void setShape(Shape shape);
 
protected:
    void paintEvent([qtclass]QPaintEvent[/qtclass] *event);
 
private:
    Background background;
    Shape shape;
    QHash<Shape,QPainterPath> shapeMap;
};
#endif // DISPLAYWIDGET_H
 
 
 here is my displaywidget.cpp:
 
 
#include <QtGui>
#include "displaywidget.h"
 
DisplayWidget::DisplayWidget([qtclass]QWidget[/qtclass] *parent)
    : QWidget(parent)

    [qtclass]QPainterPath[/qtclass] RStar;
 
    [qtclass]QFile[/qtclass] file(":SVGGenerator/files/*.svg");
    file.open(QFile::ReadOnly);
    [qtclass]QDataStream[/qtclass] stream(&file);
    stream >> RStar >> BStar;
    file.close();
 
    shapeMap[RStar] = RStar; [COLOR="#FF0000"]// no match for 'operator[]' in  '((DisplayWidget*)this)->DisplayWidget::shapeMap[RStar]'[/COLOR]
    shapeMap[BStar] = BStar;[COLOR="#FF0000"] // no match for 'operator[]' in  '((DisplayWidget*)this)->DisplayWidget::shapeMap[BStar]'[/COLOR]
 
    background = BBackground;
    shape = BStar;          [COLOR="#FF0000"]// cannot convert 'QPainterPath' to 'DisplayWidget::Shape' in assignment[/COLOR]
}
 
void DisplayWidget::paintEvent([qtclass]QPaintEvent[/qtclass] * /* event */)
{
    [qtclass]QPainter[/qtclass] painter;
    painter.begin(this);
    painter.setRenderHint(QPainter::Antialiasing);
    paint(painter);
    painter.end();
}
 
void DisplayWidget::paint([qtclass]QPainter[/qtclass] &painter)
{
    painter.setClipRect(QRect(0, 0, 200, 200));
    painter.setPen(Qt::NoPen);
 
 
 
    painter.setPen(Qt::black);
    painter.translate(100, 100);
    painter.drawPath(shapeMap[shape]);
}
 
void DisplayWidget::setBackground(Background background)
{
    this->background = background;
    update();
}
 
void DisplayWidget::setShape(Shape shape)
{
    this->shape = shape;
    update();
}

}

To copy to clipboard, switch view to plain text mode 

when I try to run this I get the commented errors on my .cpp file. I added all of my .svg files to every file in my project but still I have these errors. Can somebody help me?

Your local variables QPainterPath BStar & QPainterPath RStar are conflicting with your Shape enum.
Please, next time, use CODE tags.
