Is it possible to fill color in bounding rectangle?

No, because QRectF and all similars are shapes, or really just the coordinates of shapes. They do not have attributes like "fill" or "color". Those come only where you draw such a shape.

So , in the above code, can I use paintbrush object to color the interior of boundingRect and return the edited one?

That code only calculates the position and dimensions of the rectangle. It does not draw the rectangle, as @JonB said.

Do you already have any code that performs drawing?

    QRectF rectangle(10.0, 20.0, 80.0, 60.0);

    // Cutomised Pen; color:black , style:dashed
    QPen dashpen;
    dashpen.setStyle(Qt::DashLine);
    dashpen.setColor(Qt::black);

   
    QBrush bdashrec;
    QColor orange;
    orange.setRgb(255,140,0);
    bdashrec.setStyle(Qt::SolidPattern);
    bdashrec.setColor(orange);

    painter.setPen(dashpen);
    painter.setBrush(bdashrec);

    painter.drawRect(rectangle);

In the above code, I am drawing the rectangle, making its edge dashed, and then filling color in it
but I wanted to just fill colors to a textbox, so tried with this one.

@Swati777999
This is the right way to do the filling --- into the QPainter. I'm not sure if you are still asking the same question as earlier? As stated, QRectF is just a rectangle's coordinates and cannot contain a color or a fill itself.

Is it possible to fill color to a textbox ? or just do as the above and then put a QLabel inside it?

@Swati777999 What Qt class do you mean with "textbox"?

It's not a Qt class, in general how text-box is represented in [Untitled] By default Paint Application of Windows OS.

@Swati777999
I don't know what Windows Paint uses for what, you need to start by deciding what you are going to use in Qt for this textbox before you worry about filling it with color.

P.S.
If you are actually looking to write some Paint-type application, you might want to use QGraphicsScene for drawing and QGraphicsTextItem for your text? The Scribble Example is a Paint-type app, and you could add QGraphicsTextItems to that.

I'm afraid I don't fully understand your descriptions or what you're trying to do. Can you please describe what you have already implemented, and what changes you want to make?

If you just want to fill the background colour of a QLabel, you can apply a stylesheet to the label: https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qframe

For example, label->setStyleSheet("background-color: red;");

Thanks. This works for me.
