    Search the forum, please. Hint: search for "rounded corners".

    Or you can use stylesheets.

    Thanx for the replies

    When I use this


    Qt Code:
    1. static QRegion roundedRect(const QRect& rect, int r)
    2. {
    3. QRegion region;
    4. // middle and borders
    5. region += rect.adjusted(r, 0, -r, 0);
    6. region += rect.adjusted(0, r, 0, -r);
    7. // top left
    8. QRect corner(rect.topLeft(), QSize(r*2, r*2));
    9. region += QRegion(corner, QRegion::Ellipse);
    10. // top right
    11. corner.moveTopRight(rect.topRight());
    12. region += QRegion(corner, QRegion::Ellipse);
    13. // bottom left
    14. corner.moveBottomLeft(rect.bottomLeft());
    15. region += QRegion(corner, QRegion::Ellipse);
    16. // bottom right
    17. corner.moveBottomRight(rect.bottomRight());
    18. region += QRegion(corner, QRegion::Ellipse);
    19. return region;
    20. }
    21.  
    22. someWidget->setMask(roundedRect(someWidget->rect(), 20));
    To copy to clipboard, switch view to plain text mode 

    All the corners of the widget get rounded , and I want only the bottom left and bottom right corners

    If in the above code ,I wont make calculations for the top left and top right corners then

    some part of the top left and top right corners is subtracted from the widget.

    You're creating a mask by putting together a combination of quarter circles and rectangles. Just think about how to build that. You'll need one rectangle for the widget minus the bottom edge, so width() and height()-r. Then you'll want the bottom left and right corners as shown above, and the bottom edge between the corners (width()-2*r and height is r)
