            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

                          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

                                @MrShawn said in how to show LED in GUI and use push button to control it:

                                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.

                                -Shawn

                                if i want to set radio buttons colors to different colors how to change the code?
                                (i want some green radiobuttons some red etc...)

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

                                      You can use names.
                                      this is a MUST read.
                                      https://doc.qt.io/Qt-5/stylesheet-syntax.html

                                      QRadioButton#Name::indicator xxxxx

                                      but i think the other leds you found will work better for this that style sheet. but
                                      it should be doable.

                                          well i imagined you defined a big style sheet with
                                          the names of all the LED
                                          and set it once.
                                          then hide() /show them

                                          you can set stylesheet on mainwindow and it affects them also
                                          no need to do directly on radiobutton.
