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

        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.

          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:
          0_1531841532556_456.JPG

          After maximize:
          0_1531841582839_4561.JPG

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

              another question:
              i used this command to full screen the main window:
              resize(QDesktopWidget().availableGeometry(this).size());

              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

                          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.

                                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)
                                {

                                        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

                                here is the result:

                                alt text

                                when showing one LED the other one is affected!

                                  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.

                                      If you right click main window and select Change stylesheet
                                      you can put all lines there
                                      QRadioButton#radioButton_2::xxx
                                      QRadioButton#radioButton_3::xxx
                                      QRadioButton#radioButton_4::xxx

                                      for the colors u want.

                                      all of it. for all names. and the default one.

                                      then its always in effect.

                                      and then just
                                      ui->radioButton->show()/hide()

                                      how many leds will there be ?

                                        there will be 3 or 4 groups and about 10 to 15 LED's in each group

                                          Ok, im a bit concerned about using names directly
                                          ui->radioButton_2->show();
                                          wont that become tons of names ?
