Border for Class inheriting QWidget and QDialog

[SGaist]

Hi,

Why the double inheritance ? QDialog is already a QWidget.

Hi,

No i have inherited from QWidget,
sorry about question. rephrased
i asked if we have inherited either from QDialog or QWidget, how can we have border for the main widget not to its child ?.

if i use

this.setStyleSheet("QWidget{border:2px solid black}");

or

this.setStyleSheet("QDialog{border:2px solid black}");

it is providing border for the child widgets too, reading the docs i came to know this cant be done.

I only want to have border for main widget, not for its children.

Please provide guidance,

Thanks,

Just name your parent object with ->setObjectName("Pradeep") then use object name selector # in the css.

#Pradeep {

}

@Pradeep-Kumar said in Border for Class inheriting QWidget and QDialog:

Hi
Well test some more. It does work.
If I place widget and do
ui->widget->setObjectName("hello");
ui->widget->setWindowFlags(Qt::FramelessWindowHint);
ui->widget->setStyleSheet("#hello{border:2px solid black}");

i get

So naming the widget does work :)

[Pradeep Kumar]

Widget::Widget(QWidget *parent)
: QWidget(parent)
{
this->setObjectName("hello");
this->setWindowFlags(Qt::FramelessWindowHint);

this->setStyleSheet(
            "#hello{"
            "border: 2px solid grey;"
            "padding: 6px; }"
            );

}

My Class Name is Widget , how to make use of it?.

Thanks,

Hi,

IIRC:

"Widget{"
"border: 2px solid grey;"
"padding: 6px; }"

I'd suggest giving your class a more sensible name (even MyWidget will do). I can already see the hair pulling debugging session because nobody notices there's a missing Q before Widget.

Hi @Pradeep-Kumar

You can draw a rectangle of your screen size it can be looks like border.

drawRect(this->rect())

Hi,

if i use paintevent to get the border for the main widget.

void Widget::paintEvent(QPaintEvent *event)
{

QPainter painter(this);

QPen oMainBorderQPen;
oMainBorderQPen.setWidth(1);
oMainBorderQPen.setColor("black");

painter.setPen(oMainBorderQPen);
painter.drawRect(this->rect());

}

i am getting the border only for top and left , but for bottom and right i am no getting the border.

@Pradeep-Kumar if you set the width and height 1 pixel less you might see it. I have had to do that in the past.
