Why does not the icon appear on the button?

haifisch

I do in QTableView, a button with the help of delegates, but why the icon on the button is not displayed.
Code:

...
    //paint
    void ButtonDeleteColumnDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
    {
        QStyleOptionButton button;
        QRect r = option.rect;//getting the rect of the cell
        int x,y,w,h;
        x = r.left() + r.width() - 32;//the X coordinate
        y = r.top();//the Y coordinate
        w = 32;//button width
        h = 32;//button height
        button.rect = QRect(x,y,w,h);
        //button.text = "Удалить запись и файл";

        button.icon = QIcon(":/mapicons/deleting.png");;
        button.iconSize = QSize(32,32);
        button.state = QStyle::State_Enabled;
        QApplication::style()->drawControl( QStyle::CE_PushButton, &button, painter);
    }
    //updateGeometry
    bool ButtonDeleteColumnDelegate::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index)
    {
        if( event->type() == QEvent::MouseButtonRelease )
        {
            QMouseEvent * e = (QMouseEvent *)event;
            int clickX = e->x();
            int clickY = e->y();

            QRect r = option.rect;//getting the rect of the cell
            int x,y,w,h;
            x = r.left() + r.width() - 32;//the X coordinate
            y = r.top();//the Y coordinate
            w = 32;//button width
            h = 32;//button height

            if( clickX > x && clickX < x + w )
                if( clickY > y && clickY < y + h )
                {
                    DialogDeleteROW->setWindowTitle(tr("Удалить запись и файл"));

                    Id = model->data(model->index(index.row(),0)).toString();
                    NameFile = model->data(model->index(index.row(),1)).toString();
                    if (DisplayMethod == "data") {
                        File = model->data(model->index(index.row(),2)).toString();
                    }
                    modelDeleteRow = model;
                    DeleteRow = index.row();
                    IdLineEdit->setText(model->data(model->index(index.row(),0)).toString());
                    FileNameLineEdit->setText(model->data(model->index(index.row(),1)).toString());
                    IdLineEdit->setEnabled(false);
                    FileNameLineEdit->setEnabled(false);
                    QLabel *FileNameLabel;
                    if (DisplayMethod == "data") {
                        FileNameLabel = new QLabel(tr("Название файла."));
                    } else if (DisplayMethod == "analysis") {
                        FileNameLabel = new QLabel(tr("Поле сведенья."));
                    }
                    layout->addWidget(IdLabel,0,0);
                    layout->addWidget(FileNameLabel,1,0);
                    layout->addWidget(IdLineEdit,0,1);
                    layout->addWidget(FileNameLineEdit,1,1);

                    connect(DeleteButton,SIGNAL(clicked(bool)),SLOT(DeleteFunction()));
                    layout->addWidget(DeleteButton,2,0,1,2);
                    DialogDeleteROW->setLayout(layout);
                    QRect screenGeometry = QApplication::desktop()->screenGeometry();
                    int x = (screenGeometry.width() - DialogDeleteROW->width()) / 2;
                    int y = (screenGeometry.height() - DialogDeleteROW->height()) / 2;
                    DialogDeleteROW->move(x,y);
                    DialogDeleteROW->show();
                }
        }

        return true;
    }
    ...

The pictures are Observation Log \ map icons \ deleting.png

Hi
If you go to resource file, find the icon and RIGHT click it.
Does the path mathes the one in code ?

@mrjj I do not have this. How do I configure this option?

@mrjj or put a standard icon ```
QStyle::SP_TrashIcon

Hi
you have to put the icons in a resource file.
It seems you have just added the images as "other files"
For the ":/path/image.png" syntax to work, they must be in qresource file.
