qt.QFont(arg)

Expression qt.QFont(arg) returns a new font object. Argument arg may be a string previously returned by qfont:tostring() or a table whose fields specify the desired font characteristics. The following fields are recognized, listed in order of priority:

String field family may contain a comma separated list of the desired font families.

Setting boolean field sans to true indicates a preference for sans serif font families such as "Helvetica". This is more portable than specifying a family.

Setting boolean field serif to true indicates a preference for serif font families such as "Times". This is more portable than specifying a family.

Setting boolean field typewriter to true indicates a preference for a fixed width font families such as "Courier". This is more portable than specifying a family.

Numerical field size specify the desired size of the font. The default size is 10 points.

Numerical fields pixelSize and pointSize also indicates the desired size of the font. Field pixelSize is an alias for size. Field pointSize includes a correction factor corresponding to the actual resolution of the target device.

Numerical field weight defines the weight of the font. Weight 50 corresponds to a normal font and weight 75 corresponds to a bold font.

Numerical field stretch is a percentage applied to the width of all characters. Value 100 corresponds to a normal width. Value 150 increases all width by 50 percent.

Setting boolean field bold to true requests a bold font if the selected font family defines a bold variant.

Setting boolean field italic to true requests and italic font if the selected font family defines an italic or oblique variant.

Setting boolean field fixedPitch to true requests a fixed pitch font if the selected font family defines such a variant (rare).

Setting boolean field underline to true draws a line below all the character at a font-specified position.

Setting boolean field overline to true draws a line above all the character at a font-specified position.

Setting boolean field strikeOut to true draws a line that crosses the character at a font-specified position.

  w:show("foo")
  w:setfont(qt.QFont{serif=true,size=12,italic=true,underline=true})
  w:setcolor("blue")
