i am sending my code along with this..

QWidget *centralWidget = new QWidget;
    selectedDate=QDate::currentDate();
    int count=1,i,j;
    QPushButton *button[10][10];
    QHBoxLayout *controlsLayout = new QHBoxLayout;
    for(i=0;i<7;i++)
    {
        for(j=0;j<7;j++)
        {
            if(count<=42)
            {
 
 
                button[i][j] = new QPushButton("p");
 
                button[i][j]->resize(40,40);
 
                button[i][j]->move(40*j, 40*i);
 
                button[i][j]->show();
 
                controlsLayout->addWidget(button[i][j]);
 
                centralWidget->setLayout(controlsLayout);
 
                setCentralWidget(centralWidget);
 
                count++;
            }
 
        }
 
    }
 
  }

QWidget *centralWidget = new QWidget;
    selectedDate=QDate::currentDate();
    int count=1,i,j;
    QPushButton *button[10][10];
    QHBoxLayout *controlsLayout = new QHBoxLayout;
    for(i=0;i<7;i++)
    {
        for(j=0;j<7;j++)
        {
            if(count<=42)
            {


                button[i][j] = new QPushButton("p");

                button[i][j]->resize(40,40);

                button[i][j]->move(40*j, 40*i);

                button[i][j]->show();

                controlsLayout->addWidget(button[i][j]);

                centralWidget->setLayout(controlsLayout);

                setCentralWidget(centralWidget);

                count++;
            }

        }

just use a gridlayout for this.

[Anshuman]

I hv try it using grid layout also..

[squidge]

then your doing it wrong.

Alternatively, you could a QVBoxLayout and a QHBoxLayout for each line.

hello squidge

yeh u r right..its working now by using grid layout..now hw can i decrease the space between each rows..moreever hw can i add textBrowser below..after all buttons are arranged in rows and colums..

my code is:u plz check it..

QWidget *centralWidget = new QWidget;
    selectedDate=QDate::currentDate();
    int count=1,i,j;
 
    QPushButton *button[10][10];
    QGridLayout *controlsLayout = new QGridLayout;
     [B]QTextBrowser *T=new QTextBrowser()  //how can i add this text browser below after all the array of buttons are set[/B]
    for(i=0;i<7;i++)
    {
 
        for(j=0;j<7;j++)
        {
 
 
            if(count<=42)
            {
 
                button[i][j] = new QPushButton(QString::number(count));
 
                button[i][j]->resize(40,40);
 
                button[i][j]->move(40*j, 40*i);
 
                button[i][j]->show();
 
                controlsLayout->addWidget(button[i][j],i,j);
 
 
 
                controlsLayout->setSpacing(0);
 
                centralWidget->setLayout(controlsLayout);
 
                setCentralWidget(centralWidget);
 
                count++;
            }
 
        }
 
 
    }

QWidget *centralWidget = new QWidget;
    selectedDate=QDate::currentDate();
    int count=1,i,j;

    QPushButton *button[10][10];
    QGridLayout *controlsLayout = new QGridLayout;
     [B]QTextBrowser *T=new QTextBrowser()  //how can i add this text browser below after all the array of buttons are set[/B]
    for(i=0;i<7;i++)
    {

        for(j=0;j<7;j++)
        {


            if(count<=42)
            {

                button[i][j] = new QPushButton(QString::number(count));

                button[i][j]->resize(40,40);

                button[i][j]->move(40*j, 40*i);

                button[i][j]->show();

                controlsLayout->addWidget(button[i][j],i,j);



                controlsLayout->setSpacing(0);

                centralWidget->setLayout(controlsLayout);

                setCentralWidget(centralWidget);

                count++;
            }

I suggest to read some tutorials about layouts...

[Anshuman]

hello nish

yeh by using gridlayout its workin now...the only thing is that …hw can i decrease the space between each row…
As i had used all this in my code …but its not working..
QGridLayout::setSpacing()
QGridLayout ::setHorizontalSpacing()
QGridLayout ::setVerticalSpacing()

[squidge]

The easiest way would be to do the same effect in designer and edit the properties until you get your desired effect and then check the generated output. The designer properties should also give you a clue as to what needs changing.

Or you could just read the documentation of QWidget which QPushButton inherits.

use setContentMargins() for spacing.
