Detailed Description

A Pango::TabArray contains an array of tab stops.

Each tab stop has an alignment and a position.

explicit

TabArray() [6/6]

Pango::TabArray::TabArray ( const Glib::ustring &  text )

explicit

Deserializes a Pango::TabArray from a string.

This is the counterpart to to_string(). See that function for details about the format.

Since pangomm 2.54:

Parameters

text

A string.

Returns

A new Pango::TabArray.

Member Function Documentation

get_decimal_point()

gunichar Pango::TabArray::get_decimal_point

(

int

tab_index

)

const

Gets the Unicode character to use as decimal point.

This is only relevant for tabs with Pango::TabAlign::DECIMAL alignment, which align content at the first occurrence of the decimal point character.

The default value of 0 means that Pango will use the decimal point according to the current locale.

Since pangomm 2.54:

Parameters

tab_index

The index of a tab stop.

get_positions_in_pixels()

bool Pango::TabArray::get_positions_in_pixels

(

)

const

Returns true if the tab positions are in pixels, false if they are in Pango units.

Returns

Whether positions are in pixels.

get_size()

int Pango::TabArray::get_size

(

)

const

Gets the number of tab stops in tab_array.

Returns

The number of tab stops in the array.

get_tab()

std::pair< TabAlign, int > Pango::TabArray::get_tab

(

int

tab_index

)

const

Gets the alignment and position of a tab stop.

Returns

An std::pair<TabAlign, int>. The first element represents the tab stop alignment, the second one is the tab position.

get_tabs()

std::vector< std::pair< TabAlign, int > > Pango::TabArray::get_tabs

(

)

const

Gets an array of std::pairs containing the tab stop alignments and tab positions.

Returns

An array of std::pair<TabAlign, int>. The first element in each pair represents the tab stop alignment, the second one is the tab position.

get_type()

static GType Pango::TabArray::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

PangoTabArray * Pango::TabArray::gobj ( )

inline

Provides access to the underlying C instance.

gobj() [2/2]

const PangoTabArray * Pango::TabArray::gobj ( ) const

inline

Provides access to the underlying C instance.

gobj_copy()

PangoTabArray * Pango::TabArray::gobj_copy

(

)

const

Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.

operator bool()

Pango::TabArray::operator bool ( ) const

explicit

Checks whether this TabArray is valid.

Since pangomm 2.54:

Returns

true if the TabArray is valid.

operator=() [1/2]

TabArray & Pango::TabArray::operator=

(

const TabArray &

other

)

operator=() [2/2]

TabArray & Pango::TabArray::operator= ( TabArray &&  other )

noexcept

resize()

void Pango::TabArray::resize

(

int

new_size

)

Resizes a tab array.

You must subsequently initialize any tabs that were added as a result of growing the array.

Parameters

new_size

New size of the array.

set_decimal_point()

void Pango::TabArray::set_decimal_point	(	int	tab_index,
		gunichar	decimal_point
	)

Sets the Unicode character to use as decimal point.

This is only relevant for tabs with Pango::TabAlign::DECIMAL alignment, which align content at the first occurrence of the decimal point character.

By default, Pango uses the decimal point according to the current locale.

Since pangomm 2.54:

Parameters

tab_index	The index of a tab stop.
decimal_point	The decimal point to use.

set_positions_in_pixels()

void Pango::TabArray::set_positions_in_pixels

(

bool

positions_in_pixels = true

)

Sets whether positions in this array are specified in pixels.

Since pangomm 2.54:

Parameters

positions_in_pixels

Whether positions are in pixels.

set_tab()

void Pango::TabArray::set_tab	(	int	tab_index,
		TabAlign	alignment,
		int	location
	)

Sets the alignment and location of a tab stop.

Parameters

tab_index	The index of a tab stop.
alignment	Tab alignment.
location	Tab location in Pango units.

sort()

void Pango::TabArray::sort

(

)

Utility function to ensure that the tab stops are in increasing order.

Since pangomm 2.54:

swap()

void Pango::TabArray::swap ( TabArray &  other )

noexcept

to_string()

Glib::ustring Pango::TabArray::to_string

(

)

const

Serializes a Pango::TabArray to a string.

No guarantees are made about the format of the string, it may change between Pango versions.

The intended use of this function is testing and debugging. The format is not meant as a permanent storage format.

Since pangomm 2.54:

Returns

A newly allocated string.

related

Parameters

lhs	The left-hand side
rhs	The right-hand side

wrap()

Pango::TabArray wrap ( PangoTabArray *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.

Returns

A C++ instance that wraps this C instance.
