Qt QLabel和QPushButton样式表不生效

name_label->setStyleSheet("background-image:url(:/album/album_topbar2);\
                            font-family: Noto Sans SC;\
                            font-style: normal;\
                            font-weight: normal;\
                            font-size: 30px;\
                            line-height: 43px;\
                            color: #FFFFFF;}");
remark_button->setStyleSheet("QPushButton{border-image: url(:/album/album_remark_bg);\
                               font-family: Noto Sans SC;\
                               font-style: normal;\
                               font-weight: normal;\
                               font-size: 24px;\
                               line-height: 35px;\
                               text-align: left bottom;\
                               padding-left: 20px; \
                               padding-bottom: 20px;\
                               color: rgba(255, 255, 255, 0.7);}");

背景应该是两个半透明渐变色块,但实际上此设置未生效。父窗口重写了paintEvent如下:

void ShowWidget::paintEvent(QPaintEvent *)
{
    QPainter painter(this);
    QImage * image = currentImage;

    const qreal iw = image->width();
    const qreal ih = image->height();
    const qreal wh = height();
    const qreal ww = width();

    painter.translate(ww/2, wh/2);
    painter.translate(-iw/2, -ih/2);
    painter.drawImage(0,0,*image);

}

实际结果:

img

预期结果:

img

emmm 后来发现样式表生效了,只是生效区域显示空白,不清楚是label、button部件自动加了底色,还是qwidget绘制图片的时候认为此处被遮挡,没绘制,不知道有大佬看到帮忙解惑没

最后直接把图片重绘在图片里了

painter.setCompositionMode(QPainter::CompositionMode_SourceOver);
painter.drawImage(0, 48, name_bg);
painter.drawImage(0, 900, remark_bg);
