    Question Custom Titlebar, Top-left, right border rounded; But left over part still visible

    I've implemented a custom titlebar using QToolBar. I've applied the style to it as shown below.
    Qt Code:
    1. this->setStyleSheet("background: #646464; border: 0px; border-top-left-radius: 10px; border-top-right-radius: 10px;");
    To copy to clipboard, switch view to plain text mode 
    Now I got the rounded edges, but the left-over part after the border-radius is still visible. How do I "cut" it or How do I make it transparent ?
    Thank you.

    set same stylesheet for your base widget to cut top edges.

    Hi Pradeep,

    I did apply the same stylesheet to the base widget also. But no luck. Pls find the code below. Thank you.

    Qt Code:
    1. CTitleBar::CTitleBar(QWidget *parent) :
    2. QToolBar(parent)
    3. {
    4. this->setFixedHeight(24);
    5. this->setWindowOpacity(100);
    6. this->setStyleSheet("background-color: #646464; border: 0px; border-top-left-radius: 8px; border-top-right-radius: 8px;");
    7. this->setContentsMargins(0, 0, 0, 0);
    8. setWidgetStyling();
    9. connect(closeButton, SIGNAL(clicked()), this, SIGNAL(sig_CloseButtonClicked()));
    10. }
    11.  
    12. void CTitleBar::setWidgetStyling()
    13. {
    14. holderWidget = new QWidget;
    15. holderWidget->setStyleSheet("background-color: transparent; border-top-left-radius: 8px; border-top-right-radius: 8px;");
    16. holderWidget->setMouseTracking(true);
    17. holderWidget->setContentsMargins(0, 0, 0, 0);
    18. this->addWidget(holderWidget);
    19.  
    20. titleLyt = new QHBoxLayout();
    21. titleLyt->setContentsMargins(0, 0, 0, 0);
    22. holderWidget->setLayout(titleLyt);
    23.  
    24. closeButton = new QToolButton();
    25. closeButton->setMouseTracking(false);
    26. closeButton->setText("X");
    27. closeButton->setContentsMargins(0, 0, 0, 0);
    28. closeButton->setToolButtonStyle(Qt::ToolButtonTextOnly);
    29. closeButton->setFixedSize(20, 20);
    30. closeButton->setStyleSheet("QToolButton { color: white; font-size: 12px; background: #ec6c3f; border: 0px; border-radius: 8px;}"
    31. "QToolButton: hover { color: lightGray; background: #e44d2e; padding: 0px; border: 2px solid #f9d654;}"
    32. "QToolButton: pressed {color: lightGray; font-size: 9px; background: #ec633f; border: 0px solid #f9d456;}");
    33.  
    34. titleIcon = new QLabel();
    35. titleIcon->setPixmap(QPixmap(TRAY_ICON));
    36. titleIcon->setStyleSheet("border: none; background: transparent;");
    37.  
    38. titleText = new QLabel(APP_NAME);
    39. titleText->setContentsMargins(0, 0, 0, 0);
    40. titleText->setStyleSheet("color: orange; font: Arial; font-weight: bold; font-size: 12px");
    41.  
    42. titleLyt->addWidget(titleIcon);
    43. titleLyt->addWidget(titleText, 2);
    44. titleLyt->addWidget(closeButton);
    45. }
    To copy to clipboard, switch view to plain text mode

    where your creating instance for CTitleBar set stylesheet for that widget.
    CTitleBar *pToolbar = new CTitleBar (this);
    this->setStyleSheet("background-color: transparent; border-top-left-radius: 8px; border-top-right-radius: 8px;");
    should work ...

    I guess you are using the CTitleBar to replace the system provided title bar by using setWindowFlags(Qt::FramelessWindowHint) on the top level widget. In such case you also need to set the translucent attribute setAttribute(Qt::WA_TranslucentBackground); on the top level widget.
    When you know how to do it then you may do it wrong.
    When you don't know how to do it then it is not that you may do it wrong but you may not do it right.
