      I think you need to use
      @setCentralWidget @ first

          oops, I meant
          @
          centralWidget()->setLayout(mainLayout);
          @

          Eddy, looks like it is form created from designer, so central widget should be there.

            Tabs is the class derived from QMainWindow ? Can you show us the header and part of the code where you instantiate the Tabs class ?

                Did you use it like this ? :

                this is the way moc does it when looking in the ui_tabs.h file
                @centralwidget = new QWidget(Tabs); // it is just a temporary name
                ...
                Tabs->setCentralWidget(centralwidget);@

                @Denis
                Yes, you are right!

                  Tabs::Tabs(QWidget *parent) :
                  QMainWindow(parent),
                  ui(new Ui::Tabs)

                  tabWidget = new QTabWidget;
                  tabWidget->addTab(new QWidget,tr("History"));
                  tabWidget->addTab(new QWidget,tr("Calender"));
                  tabWidget->addTab(new QWidget,tr("Statistics"));

                    have a look at
                    @indexOf()@

                      @QTabWidget::widget(int index)@ return the tab page.
                      Then you can create buttons with returned parent.

                          You can event add custom widgets to the tab widget, so go this way:

                          @
                          Tabs::Tabs(QWidget *parent) :
                          QMainWindow(parent),
                          ui(new Ui::Tabs)
                          {
                          ui->setupUi(this);
                          tabWidget = new QTabWidget;

                          QWidget* pHistory = new QWidget;
                          // fill pHistory here
                          QPushButton* p = new QPushButton(tr("my text"), pHistory);
                          
                          
                          tabWidget->addTab(pHistory,tr("History"));
                          tabWidget->addTab(new QWidget,tr("Calender"));
                          tabWidget->addTab(new QWidget,tr("Statistics"));
                          mainLayout = new QVBoxLayout;
                          mainLayout->addWidget(tabWidget);
                          centralWidget()->setLayout(mainLayout);
                          

                          }

                            in that case use cinrin's solution :

                            for example :

                            @ QPushButton* ppp = new QPushButton("testing" );
                            QHBoxLayout* hhh = new QHBoxLayout();
                            hhh->addWidget(ppp);
                            ui->tabWidget->widget(1)->setLayout(hhh);@

                            I set up an example layout for you to control size and position.

                            EDIT : this time Gerolf was faster ;)

                              gerolf,

                              yea i could make buttons. Now im working on somethin a bit more complex than a single button.
                              I have made a calender using an array of buttons, its the same thing like the default calender.

                              Would it be possible to put in the whole calender in to one of the tab, jus as you have created a single button.???
                              It requires mainly 4 funtions to create the whole calender
                              @
                              initMemberVariable();

                              initMonthYear();
                              
                              initWeekDay();
                              
                              createLayout();

                              for(int i=0;i<6;i++)
                              {
                                  for(int j=0;j<7;j++)
                                  {
                              
                                     cellBut[i][j]=new QPushButton(this);
                                     connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));
                                     cellBut[i][j]->setFlat(true);
                              
                                  }
                              }
                              return true;
                              

                              }
                              @

                              This is where the buttons are created. I want them to be created in the calender tab.

                              Could you guide me on how to go abt it?

                                        bq. This is where the buttons are created. I want them to be created in the calender tab.
                                        Could you guide me on how to go abt it?

                                        try this

                                        @ QGridLayout* grid = new QGridLayout();

                                        for(int i=0;i<6;i++)     {
                                            for(int j=0;j<7;j++)         {
                                                cellBut[i][j]=new QPushButton(QString("%1 , %2").arg(i).arg(j));
                                                connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));
                                                cellBut[i][j]->setFlat(true);
                                                grid ->addWidget(cellBut[i][j],i,j);
                                            }
                                        }
                                        
                                        ui->tabWidget->widget(1)->setLayout(grid );@

                                          Thanks everybody :)

                                          got it fixed :) this is wat Ive used jus in case somebody else needs it. My calender is put in vlayout. so my tabwidget has now the vLayout.

                                          @

                                          QVBoxLayout *vLayout=new QVBoxLayout;
                                          tabWidget = new QTabWidget;
                                          QWidget* pCalender = new QWidget;
                                          QWidget* pHistory = new QWidget;
                                          QWidget* pStatistics= new QWidget;
                                          tabWidget->addTab(pCalender,tr("Calender"));
                                          tabWidget->addTab(pHistory,tr("History"));
                                          tabWidget->addTab(pStatistics,tr("Statistics"));
                                          tabWidget->widget(0)->setLayout(vLayout);
                                          

                                          @

                                          Last one, how to show another form when i click a tab. I have a function to show the history form. how do i call the functionwithout having to put a button on the History Tab??? :(

                                          alfah
