Constructor & Destructor Documentation

Mezzanine::UI::RightToLeftTextLine::RightToLeftTextLine ( TextLayer * ParentLayer)

Class constructor.

Parameters

ParentLayer The TextLayer that this TextLine belongs to.

Definition at line 472 of file textline.cpp.

Member Function Documentation

Boolean Mezzanine::UI::RightToLeftTextLine::AppendCharacters	(	TextLine::CharacterIterator	First,
		TextLine::CharacterIterator	Last
	)

virtual

Adds a series of Characters to the end of this TextLine.

Parameters

First	Iterator to the first Character in the series to be added.
Last	Iterator to one passed the last Character in the series to be added.

Returns: Returns true if all characters were successfully added, false otherwise.

Implements Mezzanine::UI::TextLine.

Definition at line 519 of file textline.cpp.

TextLine::CharacterIterator Mezzanine::UI::RightToLeftTextLine::AppendFittingCharacters	(	TextLine::CharacterIterator	First,
		TextLine::CharacterIterator	Last
	)

virtual

Implements Mezzanine::UI::TextLine.

Definition at line 554 of file textline.cpp.

void Mezzanine::UI::RightToLeftTextLine::AppendToBack ( Character * ToAppend)

protectedvirtual

Adds a character such that it becomes the last in the sequence.

Implements Mezzanine::UI::TextLine.

Definition at line 498 of file textline.cpp.

void Mezzanine::UI::RightToLeftTextLine::AppendToBack	(	TextLine::CharacterIterator	First,
		TextLine::CharacterIterator	Last
	)

protectedvirtual

Adds a series of characters to the end of this line.

Implements Mezzanine::UI::TextLine.

Definition at line 503 of file textline.cpp.

Real Mezzanine::UI::RightToLeftTextLine::GetCursorStartPosition ( ) const

virtual

Gets the offset position of the cursor based on the text order of the layer this text line belongs to.

Returns: Returns the left most cursor position if text is ordered left to right, and vice versa.

Implements Mezzanine::UI::TextLine.

Definition at line 511 of file textline.cpp.

TextLine::CharacterIterator Mezzanine::UI::RightToLeftTextLine::GetFirstCharacter ( )

virtual

Gets the first character in this TextLine.

Note: The first character is based on the order in which the characters are read. If the characters are meant to be read left-to-right then this will be the left most character. If the characters are meant to be read right-to-left, this will be the right most character.

Returns: Returns an iterator to the first character in this TextLine.

Implements Mezzanine::UI::TextLine.

Definition at line 592 of file textline.cpp.

TextLine::CharacterIterator Mezzanine::UI::RightToLeftTextLine::GetLastCharacter ( )

virtual

Gets the last character in this TextLine.

Note: The last character is based on the order in which the characters are read. If the characters are meant to be read left-to-right then this will be the right most character. If the characters are meant to be read right-to-left, this will be the left most character.
