          @RiceBall Please show the whole content of your MainWindow constructor, especially line 31.
          I guess it is the one you posted in a screen-shot before? It would be helpful if you would simply copy/paste the code instead of posting screen-shots.
          It looks like your scene was not yet initialised.

                No.I don't set any scene.
                Should I need to set it by " QGraphicsScene scene " at mainwindow.cpp ??? Or Not ?

                  @RiceBall Well https://doc.qt.io/qt-5/qgraphicsview.html#scene says
                  "Returns a pointer to the scene that is currently visualized in the view. If no scene is currently visualized, 0 is returned."
                  I would say you have to set a scene as shown here https://doc.qt.io/qt-5/qgraphicsview.html

                  QGraphicsScene scene;
                  scene.addText("Hello, world!");
                  
                  QGraphicsView view(&scene); // use setScene() instead
                  view.show();

                        Hi
                        Please notice you are killing the scene very fast.
                        Make it a member of the class.
                        Should live in class so it dont go out of scope,

                          @RiceBall Please think about what you're doing instead of blindly copy/paste code snippets which meant to be simple examples.
                          First: don't create the scene on the stack!
                          Second: pass pointer to setScene (the error message actually tells you what is wrong).

                                Hi @RiceBall

                                QWidget has an option to set the windowOpacity.

                                QGraphicsView *gView = new QGraphicsView(this);
                                QGraphicsScene *scene = new QGraphicsScene;
                                
                                QSvgWidget *svgWid = new QSvgWidget(":/Freesample.svg");
                                svgWid->setWindowOpacity(0.5); // Change as needed
                                scene->addWidget(svgWid);

                                Output:

                                  I have some problem.

                                  1. I can't loading several SVG. If I loading several file. It just only show last one.
                                  2. I use UI screen to set background-color:black. And I am sure my SVG is none background color.
                                    But when I loading it . It always show white background.

                                    1. I can't loading several SVG. If I loading several file. It just only show last one.
                                    2. I use UI screen to set background-color:black. And I am sure my SVG is none background color.
                                      But when I loading it . It always show white background.

                                    Result

                                    Is the code at the bottom of your post the one you're using to load SVGs? Maybe they are simply all at same position, so you only see the last one?

                                      No. They are at different position.
                                      It looks like below.

                                        Hi @RiceBall
                                        Can you please create the CustomWidget inheriting from QWidget with Some Layout in it to align the SVG contents.

                                        // Please customize the Class as per your requirement.
                                        // I just provided some dummy sample code.
                                        

                                        Example:
                                        class CustomWidget : public QWidget

                                            QGridLayout *glyt = new QGridLayout;
                                        
                                            QSvgWidget *svgWid1 = new QSvgWidget(":/Freesample.svg");
                                            QSvgWidget *svgWid2 = new QSvgWidget(":/Freesample.svg");
                                            QSvgWidget *svgWid3 = new QSvgWidget(":/Freesample.svg");
                                            QSvgWidget *svgWid4 = new QSvgWidget(":/Freesample.svg");
                                        
                                            glyt->addWidget(svgWid1);
                                            glyt->addWidget(svgWid2);
                                            glyt->addWidget(svgWid3);
                                            glyt->addWidget(svgWid4);
                                        
                                            this->setLayout(glyt);
                                        
                                        

                                        Then use the CustomWidget as

                                            CustomWidget *csw = new CustomWidget;
                                        
                                            scene->addWidget(csw);
                                        

                                        Output:

                                        0_1559809391960_4.png

                                              glyt->addWidget(svgWid4);
                                          
                                              this->setLayout(glyt);
                                          
                                          

                                          Then use the CustomWidget as

                                              CustomWidget *csw = new CustomWidget;
                                          
                                              scene->addWidget(csw);
                                          

                                          Output:

                                          Might help you.

                                          All the best.

                                          Sorry, I never use that.
                                          Your meaning is I create a new class at mainwindow.h ??

                                          class CustomWidget : public QWidget
                                          {}
                                          

                                          where can I code it ?mainwindow.h or mainwindow.cpp

                                          QGridLayout *glyt = new QGridLayout;
                                          
                                             QSvgWidget *svgWid1 = new QSvgWidget("../iHMI_2/splash1.svg");
                                             QSvgWidget *svgWid2 = new QSvgWidget("../iHMI_2/splash2.svg");
                                             QSvgWidget *svgWid3 = new QSvgWidget("../iHMI_2/splash3.svg");
                                             QSvgWidget *svgWid4 = new QSvgWidget("../iHMI_2/splash4.svg");
                                          
                                             glyt->addWidget(svgWid1);
                                             glyt->addWidget(svgWid2);
                                             glyt->addWidget(svgWid3);
                                             glyt->addWidget(svgWid4);
                                          
                                             this->setLayout(glyt);
