      No its not a good way as its not an image :)
      Its a widgets and you can either new a object and insert as website shows Or use
      promotion to add it to form.
      http://doc.qt.io/qt-5/designer-using-custom-widgets.html

      So have the ledindicator.h / ledindicator.cpp in same folder as main project.
      open mainwindow.ui
      place a QWidget on the form
      Right click the widget
      choose promote
      fill in the class name and .h filename
      press Add
      Then pres promote
      run app

                  Do you mean setting a background image for the MainWindow? If so, see example

                      I made these with radio buttons.

                      I use setStyleSheet method and sent these strings:

                      /QString StyleSheetOn("QRadioButton::indicator {width: 15px; height: 15px; border-radius: 7px;} QRadioButton::indicator:unchecked { background-color: lime; border: 2px solid gray;}");
                          QString StyleSheetOff("QRadioButton::indicator {width: 15px; height: 15px; border-radius: 7px;} QRadioButton::indicator:unchecked { background-color: black; border: 2px solid gray;}");
                      
                      

                      I dont set check i simply set style sheet, I suppose you could set stylesheets for checked and unchecked and use setChecked methods.

                        thanks
                        a good solution
                        but i have a problem!
                        when i put the radio button on a location on the map and run the program, thats fine but if i maximize the window, the map gets larger and so locations will move but radio buttons remain in previous locations. i want radiobuttons to move with map in order to remain on the location.
                        before window maximize:

                        After maximize:
                        0_1531841582839_4561.JPG

                        EDIT:
                        i have used Qframe and set map as backgroundl to load the map in GUI

                            how to make the frame(map) the same size of the main window?

                              @rezaMSLM If you use layouts then it should resize automatically

                                @rezaMSLM If you use layouts then it should resize automatically

                                i use many radio buttons in different locations in the frame, if use layouts i can not put radio buttons any location that i want. in addition when resizing the main window the radio buttons move more than map locations and get moved to a wrong location.

                                  the answer that solves my problem is that "how to set frame size to the size of main window without using layouts"

                                    if i use layouts this happens:
                                    alt text

                                    you see that when resizing the window, the radio button is not attached to the map

                                      I made these with radio buttons.

                                      0_1531774374555_513fe1d2-f658-4af1-acfa-9a04da38b7a4-image.png

                                      I use setStyleSheet method and sent these strings:

                                      /QString StyleSheetOn("QRadioButton::indicator {width: 15px; height: 15px; border-radius: 7px;} QRadioButton::indicator:unchecked { background-color: lime; border: 2px solid gray;}");
                                          QString StyleSheetOff("QRadioButton::indicator {width: 15px; height: 15px; border-radius: 7px;} QRadioButton::indicator:unchecked { background-color: black; border: 2px solid gray;}");
                                      
                                      

                                      I dont set check i simply set style sheet, I suppose you could set stylesheets for checked and unchecked and use setChecked methods.

                                        the background-color controls that.
                                        you can do
                                        background-color: rgb(47, 255, 11);
                                        to set a color using RGB
