You can create a QWidget or a QFrame at the place you want to add an image. You can then use the style sheet to set a background-image on that picture. You might want to add your image to your ressources (.qrc).
您可以在要添加图像的位置创建 QWidget 或 QFrame。然后您可以使用样式表在该图片上设置背景图像。您可能希望将图像添加到资源 (.qrc) 中。
Using QtDesigner is a good idea for this kind of task.
对于此类任务，使用 QtDesigner 是一个好主意。
EDIT : Here is an easy way to do that without bothering with QPixMap.
编辑：这是一种简单的方法，无需打扰 QPixMap。
QWidget *frame = new QWidget(this);
frame->setGeometry(x, y, width, height);
frame->setStyleSheet("background-image: url(:/path/to/image.png)");
The :specifies that you want to use the path in your Qt resources. The first two lines are not needed if you define this QWidgetusing QtDesigner.
在:指定要使用的路径在你的Qt资源。如果您QWidget使用 QtDesigner定义它，则不需要前两行。
Also, don't forget to import your resources.qrc(however you called it) file (including your resources) and add this to your .pro:
另外，不要忘记导入您的resources.qrc（无论您如何称呼它）文件（包括您的资源）并将其添加到您的.pro：
RESOURCES = resources.qrc

You should use a label (QLabel). You can add a label to your form and edit its pixmapproperty in Qt Designer (you will be able to choose one of images you've added to project resources). Also you can set an image on QLabelprogrammatically using setPixmap().
您应该使用标签 ( QLabel)。您可以向表单添加标签并pixmap在 Qt Designer 中编辑其属性（您将能够选择已添加到项目资源的图像之一）。您也可以QLabel使用setPixmap().
