Font size increase in QtableWidget

[sosanjay]

Hi,

I want to increase the font size of the QTableWidget.

QFont fnt;
        fnt.setPointSize(30);
        fnt.setFamily("Arial");
ui->tableWidget->setFont(fnt);

QFont fnt;
        fnt.setPointSize(30);
        fnt.setFamily("Arial");
ui->tableWidget->setFont(fnt);

To copy to clipboard, switch view to plain text mode 

Can anyone suggest me Why it is not working?

Is setPointSize(30) is correct for font size or any other options.

If you specified item's font already, QTableWidget's font is ignored.

You can change the font size as follows.

QFont fnt;
		fnt.setPointSize(30);
		fnt.setFamily("Arial");
const int rowCount = tableWidget->rowCount();
const int columnCount = tableWidget->columnCount();
 
for(int i = 0; i < rowCount; ++i) {
	for(int j = 0; j < columnCount; ++j) {
		QTableWidgetItem* selectedItem = tableWidget->item(i, j);
		selectedItem->setFont(fnt);
	}
}

QFont fnt;
		fnt.setPointSize(30);
		fnt.setFamily("Arial");
const int rowCount = tableWidget->rowCount();
const int columnCount = tableWidget->columnCount();

for(int i = 0; i < rowCount; ++i) {
	for(int j = 0; j < columnCount; ++j) {
		QTableWidgetItem* selectedItem = tableWidget->item(i, j);
		selectedItem->setFont(fnt);
	}
}

I'm sorry in poor English.
