QTableWidget change header background color - QHeaderView

[Erik_Klein]

In Short,
Anyone has any clue on how to set background color specific per header in a table???


Guys, would really appreciate some help with this - looked everywhere and nothing working yet.

What im trying to do is to have a tablewidget with 2 distinctive horizontal header styles, so some columns headers will have a colour background whilst another columns will have a different color header background.

The thing is, the basic properties settings(right-click menu) in QT Designer for setting color background looks really buggy and simply does not work, so im trying to do this through stylesheet.

What i've done is....

QHeaderView::section
{
spacing: 10px;
background-color:lightblue;
color: white;
border: 1px solid red;
margin: 1px;
text-align: right;
font-family: arial;
font-size:12px;
}

but this applies to all the headers.
then, if i want multiple background colors, there is only one way to do it which is...

using QHeaderView::section:last or QHeaderView::section:first ,
which would be perfect IF i only had 3 headers to style, but i am working with many different tables containing 6+ columns!

Anyone has any clue on how to set background color specific per header in a table?? Appreciate any help!!

thanks,
Erik

QHeaderView::section
{
spacing: 10px;
background-color:lightblue;
color: white;
border: 1px solid red;
margin: 1px;
text-align: right;
font-family: arial;
font-size:12px;
}

but this applies to all the headers.

If you want that to applly to a specific header, you can do it manually by code.

QString styleSheet = "::section {" // "QHeaderView::section {"
                     "spacing: 10px;"
                     "background-color: lightblue;"
                     "color: white;"
                     "border: 1px solid red;"
                     "margin: 1px;"
                     "text-align: right;"
                     "font-family: arial;"
                     "font-size: 12px; }";
 
tableWidget->horizontalHeader()->setStyleSheet(styleSheet); // tableWidget->verticalHeader()->setStyleSheet(styleSheet);

QString styleSheet = "::section {" // "QHeaderView::section {"
                     "spacing: 10px;"
                     "background-color: lightblue;"
                     "color: white;"
                     "border: 1px solid red;"
                     "margin: 1px;"
                     "text-align: right;"
                     "font-family: arial;"
                     "font-size: 12px; }";

tableWidget->horizontalHeader()->setStyleSheet(styleSheet); // tableWidget->verticalHeader()->setStyleSheet(styleSheet);

To copy to clipboard, switch view to plain text mode 

then, if i want multiple background colors, there is only one way to do it which is...

Maybe, you can use QTableWidgetItem and QTableWidget::setHorizontalHeaderItem(int, QTableWidgetItem*).

QTableWidgetItem *col1 = new QTableWidgetItem("Column 1");
col1->setForeground(Qt::white);
col1->setBackground(QColor("lightblue"));
col1->setFont(QFont("arial", 12));
tableWidget->setHorizontalHeaderItem(0, col1); // tableWidget->setVerticalHeaderItem(0, col1);

QTableWidgetItem *col1 = new QTableWidgetItem("Column 1");
col1->setForeground(Qt::white);
col1->setBackground(QColor("lightblue"));
col1->setFont(QFont("arial", 12));
tableWidget->setHorizontalHeaderItem(0, col1); // tableWidget->setVerticalHeaderItem(0, col1);

But, the background color doesn't work for me.
