wxFontInfo Class Reference

#include <wx/font.h>

Detailed Description

This class is a helper used for wxFont creation using named parameter idiom: it allows specifying various wxFont attributes using the chained calls to its clearly named methods instead of passing them in the fixed order to wxFont constructors.

For example, to create an italic font with the given face name and size you could use:

wxFont font(wxFontInfo(12).FaceName("Helvetica").Italic());

Notice that all of the methods of this object return a reference to the object itself, allowing the calls to them to be chained as in the example above.

All methods taking boolean parameters can be used to turn the specified font attribute on or off and turn it on by default.

Constructor & Destructor Documentation

wxFontInfo() [1/3]

wxFontInfo::wxFontInfo

(

)

Default constructor uses the default font size for the current platform.

wxFontInfo() [2/3]

wxFontInfo::wxFontInfo ( double  pointSize )

explicit

Constructor setting the font size in points to use.

Note that until wxWidgets 3.1.2 fractional point sizes were not supported, and the type of pointSize was int.

See also

wxFont::SetPointSize()

wxFontInfo() [3/3]

wxFontInfo::wxFontInfo ( const wxSize &  pixelSize )

explicit

Constructor setting the font size in pixels to use.

See also

wxFont::SetPixelSize()

Member Function Documentation

AllFlags()

wxFontInfo & wxFontInfo::AllFlags

(

int

flags

)

Set all the font attributes at once.

See wxFontFlag for the various flags that can be used.

Note that calling this method affects the font weight stored in this object: it is set to wxFONTWEIGHT_LIGHT or wxFONTWEIGHT_BOLD if the corresponding flag is present in flags, or wxFONTWEIGHT_NORMAL otherwise.

AntiAliased()

wxFontInfo & wxFontInfo::AntiAliased

(

bool

antiAliased = true

)

Set anti-aliasing flag.

Force the use of anti-aliasing on or off.

Currently this is not implemented, i.e. using this method doesn't do anything.

Bold()

wxFontInfo & wxFontInfo::Bold

(

bool

bold = true

)

Use a bold version of the font.

This is a wrapper for Weight() calling it with wxFONTWEIGHT_BOLD argument.

See also

wxFontWeight, wxFont::SetWeight()

Encoding()

wxFontInfo & wxFontInfo::Encoding

(

wxFontEncoding

encoding

)

Set the font encoding to use.

This is mostly unneeded in Unicode builds of wxWidgets.

See also

wxFontEncoding, wxFont::SetEncoding()

FaceName()

wxFontInfo & wxFontInfo::FaceName

(

const wxString &

faceName

)

Set the font face name to use.

Face names are not portable, so prefer to use Family() in portable code.

See also

wxFont::SetFaceName()

Family()

wxFontInfo & wxFontInfo::Family

(

wxFontFamily

family

)

Set the font family.

The family is a generic portable way of referring to fonts without specifying a precise face name. This parameter must be one of the wxFontFamily enumeration values.

If the FaceName() is used, then it overrides the font family.

See also

wxFont::SetFamily()

GetWeightClosestToNumericValue()

static wxFontWeight wxFontInfo::GetWeightClosestToNumericValue ( int  numWeight )

static

Get the symbolic weight closest to the given raw weight value.

Parameters

numWeight

A valid raw weight value, i.e. a value in the range 1 to 1000, inclusive.

Returns

A valid element of wxFontWeight enum.

Since

3.1.2

Italic()

wxFontInfo & wxFontInfo::Italic

(

bool

italic = true

)

Use an italic version of the font.

This is a wrapper for Style() calling it with wxFONTSTYLE_ITALIC argument.

See also

wxFontStyle, wxFont::SetStyle()

Light()

wxFontInfo & wxFontInfo::Light

(

bool

light = true

)

Use a lighter version of the font.

This is a wrapper for Weight() calling it with wxFONTWEIGHT_LIGHT argument.

See also

wxFontWeight, wxFont::SetWeight()

Slant()

wxFontInfo & wxFontInfo::Slant

(

bool

slant = true

)

Use a slanted version of the font.

This is a wrapper for Style() calling it with wxFONTSTYLE_SLANT argument.

See also

wxFontStyle, wxFont::SetStyle()

Strikethrough()

wxFontInfo & wxFontInfo::Strikethrough

(

bool

strikethrough = true

)

Use a strike-through version of the font.

Currently this is only implemented in wxMSW, wxGTK, and wxOSX.

Style()

wxFontInfo & wxFontInfo::Style

(

wxFontStyle

style

)

Specify the style of the font using one of wxFontStyle constants.

Since

3.1.2

Underlined()

wxFontInfo & wxFontInfo::Underlined

(

bool

underlined = true

)

Use an underlined version of the font.

Weight()

wxFontInfo & wxFontInfo::Weight

(

int

weight

)

Specify the weight of the font.

Parameters

weight

A font weight in the range from 1 to 1000, inclusive, with 1 being the thinnest and 1000 the heaviest possible font variant. wxFONTWEIGHT_XXX values from wxFontWeight enum can be used here.

Since

3.1.2
