Table header left over on the right (Mac only issue)

[FunghiApe]

Hi experts,

This is a mac only issue. It works just fine on Windows.
The "Actions" section resize mode is set to "Fixed" and when I drag the divider between "Commands" and "Actions" sections to the left. There will be left over header (colored as grey) on the right.

What could be wrong?

Thank you!!!

I 've just added this to the header style:

"QHeaderView\
        {\
            background-color: rgba(255,255, 255);\
    }";

And the horizontal gray bar is now white.

Hi,

Can you share a minimal compilable example that shows the behaviour ?
What result are you expecting ?
Which version of Qt are you using ?
On which version of macOS ?

@SGaist Thanks for reply.

Here's how it looks in windows:

and this is how it looks in mac os 12.5

I am expecting the header to be like how it is shown in windows (no grey area on the right).
Qt version is 5.15.2

Can you please provide a minimal compilable example that shows this behaviour ?

Note that different OS may show the same controls in different ways and it might be the correct representation even if not what you expect.

Here it is:

       const QSize MiniDialogSize(586, 368);

        auto tableWidget = new QTableWidget(2, 3, this);
	tableWidget->setHorizontalHeaderItem(0, new QTableWidgetItem(QString(tr("A"))));
	tableWidget->setHorizontalHeaderItem(1, new QTableWidgetItem(QString(tr("B"))));
	tableWidget->setHorizontalHeaderItem(2, new QTableWidgetItem(QString(tr("C"))));
	tableWidget->setItem(0, 0, new QTableWidgetItem(QString("test1")));
	tableWidget->setItem(0, 1, new QTableWidgetItem(QString("test2")));
	tableWidget->setItem(0, 2, new QTableWidgetItem(QString("test3")));
	tableWidget->setItem(1, 0, new QTableWidgetItem(QString("test4")));
	tableWidget->setItem(1, 1, new QTableWidgetItem(QString("test5")));
	tableWidget->setItem(1, 2, new QTableWidgetItem(QString("test6")));

	const QString styles = "QTableWidget {background-color:rgb(255, 255, 255);\
					border: 2px solid green;}\
					QTableWidget::Item { padding-left: 6px; border: 0; font-size: 12px;}";

	const QString headerStyle = "QHeaderView::section\
	{\
		background-color: rgba(0, 100, 0, 255);\
        color: white;\
		padding-left: 10px;\
		border: 2px solid blue;\
		border-right: 1px solid red;\
		font-size: 12px;\
	}";

    tableWidget->setStyleSheet(styles);
    tableWidget->horizontalHeader()->setStyleSheet(headerStyle);
    tableWidget->setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Minimum);
    boxLayout->addWidget(tableWidget);
    resize(MiniDialogSize);

Sorry but that's not compilable as it is.
