voidqDrawBorderPixmap(QPainter * painter, constQRect & target, constQMargins & margins, constQPixmap & pixmap)

This is an overloaded function.

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

Draws the givenpixmap into the giventarget rectangle, using the givenpainter. The pixmap will be split into nine segments and drawn according to themargins structure.

This function was introduced in Qt 4.6.

voidqDrawPlainRect(QPainter * painter,int x,int y,int width,int height, constQColor & lineColor,int lineWidth = 1, constQBrush * fill = 0)

Draws the plain rectangle beginning at (x,y) with the givenwidth andheight, using the specifiedpainter,lineColor andlineWidth. The rectangle's interior is filled with thefill brush unlessfill is 0.

Warning: This function does not look atQWidget::style() orQApplication::style(). Use the drawing functions inQStyle to make widgets that follow the current GUI style.

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

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

See alsoqDrawShadeRect() andQStyle.

voidqDrawPlainRect(QPainter * painter, constQRect & rect, constQColor & lineColor,int lineWidth = 1, constQBrush * fill = 0)

This is an overloaded function.

Draws the plain rectangle specified byrect using the givenpainter,lineColor andlineWidth. The rectangle's interior is filled with thefill brush unlessfill is 0.

Warning: This function does not look atQWidget::style() orQApplication::style(). Use the drawing functions inQStyle to make widgets that follow the current GUI style.

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

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

voidqDrawShadeLine(QPainter * painter,int x1,int y1,int x2,int y2, constQPalette & palette,bool sunken = true,int lineWidth = 1,int midLineWidth = 0)

Draws a horizontal (y1 ==y2) or vertical (x1 ==x2) shaded line using the givenpainter. Note that nothing is drawn ify1 !=y2 andx1 !=x2 (i.e. the line is neither horizontal nor vertical).

The providedpalette specifies the shading colors (light,dark andmiddle colors). The givenlineWidth specifies the line width for each of the lines; it is not the total line width. The givenmidLineWidth specifies the width of a middle line drawn in theQPalette::mid() color.

The line appears sunken ifsunken is true, otherwise raised.

Warning: This function does not look atQWidget::style() orQApplication::style(). Use the drawing functions inQStyle to make widgets that follow the current GUI style.

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

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

See alsoqDrawShadeRect(),qDrawShadePanel(), andQStyle.

voidqDrawShadeLine(QPainter * painter, constQPoint & p1, constQPoint & p2, constQPalette & palette,bool sunken = true,int lineWidth = 1,int midLineWidth = 0)

This is an overloaded function.

Draws a horizontal or vertical shaded line betweenp1 andp2 using the givenpainter. Note that nothing is drawn if the line between the points would be neither horizontal nor vertical.

The providedpalette specifies the shading colors (light,dark andmiddle colors). The givenlineWidth specifies the line width for each of the lines; it is not the total line width. The givenmidLineWidth specifies the width of a middle line drawn in theQPalette::mid() color.

The line appears sunken ifsunken is true, otherwise raised.

Warning: This function does not look atQWidget::style() orQApplication::style(). Use the drawing functions inQStyle to make widgets that follow the current GUI style.

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

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

voidqDrawShadePanel(QPainter * painter,int x,int y,int width,int height, constQPalette & palette,bool sunken = false,int lineWidth = 1, constQBrush * fill = 0)

Draws the shaded panel beginning at (x,y) with the givenwidth andheight using the providedpainter and the givenlineWidth.

The givenpalette specifies the shading colors (light,dark andmiddle colors). The panel's interior is filled with thefill brush unlessfill is 0.

The panel appears sunken ifsunken is true, otherwise raised.

Warning: This function does not look atQWidget::style() orQApplication::style(). Use the drawing functions inQStyle to make widgets that follow the current GUI style.

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

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