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

                  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

                          @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 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.

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

                                  I made these with radio buttons.

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

                                      that controls all buttons color
                                      i want some red, some green and so on

                                        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.

                                          i use this code:

                                          void MainWindow::on_checkBox1_clicked(bool checked)
                                          {
                                              if(checked == true)
                                              {
                                                  ui->radioButton_2->show();
                                                  QString StyleSheetOn("QRadioButton::mainwindow {width: 25px; height: 25px; border-radius: 7px;} QRadioButton#radioButton_2::indicator:unchecked { background-color: lime; border: 2px solid gray;}");
                                                  setStyleSheet(StyleSheetOn);
                                              }
                                              else
                                              {
                                                  ui->radioButton_2->hide();
                                              }
                                          }
                                          
                                          void MainWindow::on_checkBox2_clicked(bool checked)
                                          {
                                              if(checked == true)
                                              {
                                                  ui->radioButton->show();
                                                  QString StyleSheetOn2("QRadioButton::mainwindow {width: 25px; height: 25px; border-radius: 7px;} QRadioButton#radioButton::indicator:unchecked { background-color: red; border: 2px solid gray;}");
                                                  setStyleSheet(StyleSheetOn2);
                                              }
                                              else
                                              {
                                                  ui->radioButton->hide();
                                              }
                                          
                                          
                                          }
                                          

                                          here is the result:

                                          alt text

                                          when showing one LED the other one is affected!
