为 QPushButton 设置背景图像 [英] Setting background image for QPushButton

问题描述

我正在努力为 QPushButton 设置背景图像.到现在都没有成功.以下是我的代码.

I am struggling to set an background image for an QPushButton. No Success till now. Following is my code.

appsWidget::appsWidget(QWidget *parent)
    :QWidget(parent)
{
    QPushButton *button1 = new QPushButton("SETTINGS",this);
    QPushButton *button2 = new QPushButton("TEST",this);
    QPushButton *button3 = new QPushButton("IE",this);

    button1->setStyleSheet("background-image:url(config.png)"); -> No success


    qDebug("appWidget initialized.");

    QHBoxLayout *layout = new QHBoxLayout;
    layout->addWidget(button1);
    layout->addWidget(button2);
    layout->addWidget(button3);
    this->setLayout(layout);
    connect(button1,SIGNAL(clicked()),this,SLOT(setClickIndex1()));
    connect(button2,SIGNAL(clicked()),this,SLOT(setClickIndex2()));
    connect(button3,SIGNAL(clicked()),this,SLOT(setClickIndex3()));
}

我在样式表中使用的图像位于同一个项目文件夹中.有人有解决办法吗?

The image I am using in the stylesheet is located in the same project folder. Do anybody has any solution?

推荐答案

你必须将flat属性设置为true:

You have to set the flat attribute to true:

button1->setFlat(true);

您还必须设置自动填充背景 -

You also have to set the autofillbackground -

button1->setAutoFillBackground(true);

您可能想查看 QToolButton，它不需要它是平坦的以呈现图像.我正在我正在编写的应用程序中使用它们，它们看起来非常好:

You may want to look at QToolButton which doesn't require it to be flat in order to render an image. I'm using them in an app I'm writing at the moment and they look very nice:

m_showAddCommentButton = new QToolButton();
m_showAddCommentButton->setAutoFillBackground(true);
palette = m_showAddCommentButton->palette();
palette.setColor(QPalette::Button,QColor(82,110,166));
m_showAddCommentButton->setPalette(palette);
m_showAddCommentButton->setIcon(QIcon(":/uiImages/addComment_50_50.jpg"));
m_showAddCommentButton->setIconSize(QSize(40,40));
m_showAddCommentButton->setToolTip("Comment");
connect(m_showAddCommentButton, SIGNAL(clicked()),
        manager, SLOT(showAddComment()));
hLayout->addWidget(m_showAddCommentButton,0);
