void qDrawBorderPixmap(QPainter *painter, const QRect &target, const QMargins &margins, const QPixmap &pixmap)

The qDrawBorderPixmap function is for drawing a pixmap into the margins of a rectangle.

Draws the given pixmap into the given target rectangle, using the given painter. The pixmap will be split into nine segments and drawn according to the margins structure.

This function was introduced in Qt 4.6.

void qDrawPlainRect(QPainter *painter, int x, int y, int width, int height, const QColor &lineColor, int lineWidth = 1, const QBrush *fill = Q_NULLPTR)

Draws the plain rectangle beginning at (x, y) with the given width and height, using the specified painter, lineColor and lineWidth. The rectangle's interior is filled with the fill brush unless fill is 0.

Warning: This function does not look at QWidget::style() or QApplication::style(). Use the drawing functions in QStyle to make widgets that follow the current GUI style.

Alternatively you can use a QFrame widget and apply the QFrame::setFrameStyle() function to display a plain rectangle:

  QFrame frame:
  frame.setFrameStyle(QFrame::Box | QFrame::Plain);

See also qDrawShadeRect() and QStyle.

void qDrawPlainRect(QPainter *painter, const QRect &rect, const QColor &lineColor, int lineWidth = 1, const QBrush *fill = Q_NULLPTR)

This is an overloaded function.

Draws the plain rectangle specified by rect using the given painter, lineColor and lineWidth. The rectangle's interior is filled with the fill brush unless fill is 0.

Warning: This function does not look at QWidget::style() or QApplication::style(). Use the drawing functions in QStyle to make widgets that follow the current GUI style.

Alternatively you can use a QFrame widget and apply the QFrame::setFrameStyle() function to display a plain rectangle:

  QFrame frame:
  frame.setFrameStyle(QFrame::Box | QFrame::Plain);

void qDrawShadeLine(QPainter *painter, int x1, int y1, int x2, int y2, const QPalette &palette, bool sunken = true, int lineWidth = 1, int midLineWidth = 0)

Draws a horizontal (y1 == y2) or vertical (x1 == x2) shaded line using the given painter. Note that nothing is drawn if y1 != y2 and x1 != x2 (i.e. the line is neither horizontal nor vertical).

The provided palette specifies the shading colors (light, dark and middle colors). The given lineWidth specifies the line width for each of the lines; it is not the total line width. The given midLineWidth specifies the width of a middle line drawn in the QPalette::mid() color.

The line appears sunken if sunken is true, otherwise raised.

Warning: This function does not look at QWidget::style() or QApplication::style(). Use the drawing functions in QStyle to make widgets that follow the current GUI style.

Alternatively you can use a QFrame widget and apply the QFrame::setFrameStyle() function to display a shaded line:

  QFrame frame:
  frame.setFrameStyle(QFrame::HLine | QFrame::Sunken);

See also qDrawShadeRect(), qDrawShadePanel(), and QStyle.

void qDrawShadeLine(QPainter *painter, const QPoint &p1, const QPoint &p2, const QPalette &palette, bool sunken = true, int lineWidth = 1, int midLineWidth = 0)

This is an overloaded function.

Draws a horizontal or vertical shaded line between p1 and p2 using the given painter. Note that nothing is drawn if the line between the points would be neither horizontal nor vertical.

The provided palette specifies the shading colors (light, dark and middle colors). The given lineWidth specifies the line width for each of the lines; it is not the total line width. The given midLineWidth specifies the width of a middle line drawn in the QPalette::mid() color.

The line appears sunken if sunken is true, otherwise raised.

Warning: This function does not look at QWidget::style() or QApplication::style(). Use the drawing functions in QStyle to make widgets that follow the current GUI style.

Alternatively you can use a QFrame widget and apply the QFrame::setFrameStyle() function to display a shaded line:

  QFrame frame:
  frame.setFrameStyle(QFrame::HLine | QFrame::Sunken);

See also qDrawShadeRect(), qDrawShadePanel(), and QStyle.

void qDrawShadePanel(QPainter *painter, int x, int y, int width, int height, const QPalette &palette, bool sunken = false, int lineWidth = 1, const QBrush *fill = Q_NULLPTR)

Draws the shaded panel beginning at (x, y) with the given width and height using the provided painter and the given lineWidth.

The given palette specifies the shading colors (light, dark and middle colors). The panel's interior is filled with the fill brush unless fill is 0.

The panel appears sunken if sunken is true, otherwise raised.

Warning: This function does not look at QWidget::style() or QApplication::style(). Use the drawing functions in QStyle to make widgets that follow the current GUI style.

Alternatively you can use a QFrame widget and apply the QFrame::setFrameStyle() function to display a shaded panel:

  QFrame frame:
  frame.setFrameStyle( QFrame::Panel | QFrame::Sunken);

void qDrawShadePanel(QPainter *painter, const QRect &rect, const QPalette &palette, bool sunken = false, int lineWidth = 1, const QBrush *fill = Q_NULLPTR)

This is an overloaded function.

Draws the shaded panel at the rectangle specified by rect using the given painter and the given lineWidth.

The given palette specifies the shading colors (light, dark and middle colors). The panel's interior is filled with the fill brush unless fill is 0.

The panel appears sunken if sunken is true, otherwise raised.

Warning: This function does not look at QWidget::style() or QApplication::style(). Use the drawing functions in QStyle to make widgets that follow the current GUI style.

Alternatively you can use a QFrame widget and apply the QFrame::setFrameStyle() function to display a shaded panel:

  QFrame frame:
  frame.setFrameStyle( QFrame::Panel | QFrame::Sunken);
