array of radio buttons

[amulya]

hi there,

i m trying to add an array of radio buttons in a grid layout and then further into a widget. but these radio buttons seem to overlap over each other. Thus in the output, there is only one radio button. Here is the code

KPH_WIDGET::KPH_WIDGET(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
	QPalette objPalette1;
	objPalette1.setColor(QPalette::Window,Qt::white);
                QPalette objPalette2;
	objPalette2.setColor(QPalette::Window,Qt::gray);
 
	//setFixedSize(300,300);
                QGridLayout* pGridLayout = new QGridLayout(this);
 
                CRadioButtonEx* arr[10] ;
	for(int i = 0; i < 10; i++)
	{
		pGridLayout->setRowMinimumHeight(i,50);
	               arr[i] = new CRadioButtonEx(tr("check"),this);
 
		if(arr[i])
		{
			if(i%2 == 0)
			arr[i]->setPalette(objPalette1);
			else
			arr[i]->setPalette(objPalette2);
 
			arr[i]->setAutoFillBackground(true);
 
 
		}
 
		pGridLayout->addWidget(arr[i],i,0,Qt::AlignLeft);
	}

KPH_WIDGET::KPH_WIDGET(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
	QPalette objPalette1;
	objPalette1.setColor(QPalette::Window,Qt::white);
                QPalette objPalette2;
	objPalette2.setColor(QPalette::Window,Qt::gray);

	//setFixedSize(300,300);
                QGridLayout* pGridLayout = new QGridLayout(this);
    
                CRadioButtonEx* arr[10] ;
	for(int i = 0; i < 10; i++)
	{
		pGridLayout->setRowMinimumHeight(i,50);
	               arr[i] = new CRadioButtonEx(tr("check"),this);
        
		if(arr[i])
		{
			if(i%2 == 0)
			arr[i]->setPalette(objPalette1);
			else
			arr[i]->setPalette(objPalette2);

			arr[i]->setAutoFillBackground(true);
			
			
		}

		pGridLayout->addWidget(arr[i],i,0,Qt::AlignLeft);
	}

Here, CRadioButtonEx is a customized radio button which works correctly. On debugging, it shows that all the 10 of the radio buttons are created. But only one is shown.

Looking forward to a reply.

try arr[i]->show(); after/before adding to layout.

Hello ,
You are trying to set your own layout in QMainWidget. Your are not supposed to do that.
Instead you should create a widget and set it as central widget of QMainWindow. You can use your own layout in centralWidget.
So try this code

QPalette objPalette1;
    objPalette1.setColor(QPalette::Window,Qt::white);
    QPalette objPalette2;
    objPalette2.setColor(QPalette::Window,Qt::gray);
    //added these two lines and modified one line
    QWidget *centralWidget = new QWidget(this);
    setCentralWidget(centralWidget);
    QGridLayout* pGridLayout = new QGridLayout(centralWidget);
 
    QRadioButton* arr[10] ;
    for(int i = 0; i < 10; i++)
    {
        pGridLayout->setRowMinimumHeight(i,50);
	arr[i] = new QRadioButton(tr("check"),this);
        if(arr[i])
        {
            if(i%2 == 0)
	      arr[i]->setPalette(objPalette1);
            else
	      arr[i]->setPalette(objPalette2);
            arr[i]->setAutoFillBackground(true);
        }
        pGridLayout->addWidget(arr[i],i,0,Qt::AlignLeft);
    }

QPalette objPalette1;
    objPalette1.setColor(QPalette::Window,Qt::white);
    QPalette objPalette2;
    objPalette2.setColor(QPalette::Window,Qt::gray);
    //added these two lines and modified one line
    QWidget *centralWidget = new QWidget(this);
    setCentralWidget(centralWidget);
    QGridLayout* pGridLayout = new QGridLayout(centralWidget);

    QRadioButton* arr[10] ;
    for(int i = 0; i < 10; i++)
    {
        pGridLayout->setRowMinimumHeight(i,50);
	arr[i] = new QRadioButton(tr("check"),this);
        if(arr[i])
        {
            if(i%2 == 0)
	      arr[i]->setPalette(objPalette1);
            else
	      arr[i]->setPalette(objPalette2);
            arr[i]->setAutoFillBackground(true);
        }
        pGridLayout->addWidget(arr[i],i,0,Qt::AlignLeft);
    }
