              @ManiRon
              you can use same SLOT for each and every 35 buttons..

              connect(Button1,SIGNAL(clicked(),this,SLOT(on_Button_clicked());
              .
              .
              connect(Button35,SIGNAL(clicked(),this,SLOT(on_Button_clicked());

              this is better help @J-Hilk

                @ManiRon said in how to create a toggle button(on/off button):

                @jsulm yes sir i am using that

                I doubt you use it to it's full potential. No need to set a new Stylesheet each time the button is pressed.

                myButton->setCheckable(true);
                myButton->setStyleSheet("
                    QPushButton{background-color:green;}
                    QPushButton:checked{background-color:red;}"
                );
                
                

                not checked -> Green color
                checked -> Red color each click a different color

                  @ManiRon instead of the predfined color naming convention, you can also use rgb values to customize it:

                  for example:

                  background-color:rgb(87,117,131);

                    @J.Hilk i tried it but the red color alone remains the same as i mention in the previous comment maybe its based on the checked selection i think so.

                    Actually I absorbed one thing . When i click the button once it changes to green but next time when i press the button it changes to how i mention in my previous comment and when i keep it pressed without releasing the color is0_1540794665691_RTO1.jpg is like the image

                      I did something like this sir

                      ui->pushButton_34->setCheckable(true);

                      if(ui->pushButton_34->isChecked())
                      {
                          ui->pushButton_34->setStyleSheet("background-color: rgb(170, 0, 0)");
                          ui->pushButton_34->setCheckable(false);
                      }
                      else
                      {
                          ui->pushButton_34->setStyleSheet("background-color: rgb(0, 170, 0)");
                      }
                      

                      is it a correct way . I was able to bring it out.

                        I believe, that is the focus rectangle that is overlaying the Pushbutton in a semi transparent way.
                        add the following to your stylesheet:

                        QPushButton:focus{border:none; }
                        
                        QPushButton *btn = new QPushButton();
                        
                            btn->setCheckable(true);
                            btn->setStyleSheet("QPushButton{background-color:red;} \
                                               QPushButton:checked{background-color:green;} \
                                               QPushButton:focus{border:none; }");
                            btn->show();

                            @ManiRon please read the docu @jsulm linked. To learn more about stylsheet and it's syntax.

                            focus{border:none;} does not mean your Qpushbutton can't not have a custom border!

                            Applying a new Stylesheet each time you click the button is, in my opinion, the worst way you could implement what you want to do.

                            But if it works for you, and you're fine with it, who am I to judge?
