Detailed Description

Some notes on markup characters supported by GUIFont functions.

• \n is a regular line feed.
• \tXXX, where XXX is decimal offset in pixels. Moves the caret to a position offset by XXX to the right from the start of the line. This is how aligned tables are implemented.
• \rXXX, where XXX is a decimal offset in pixels. Moves the caret so that the rest of the line is right-justified, with the given offset from the right window border. This is used e.g. in the create party screen.
• \fXXXXX, where XXXXX is a decimal color code for 16-bit color to use for the text that follows.

Member Function Documentation

AlignText_Center()

int GUIFont::AlignText_Center	(	int	width,
		std::string_view	str
	)

Parameters

width	Width of the rect to position the text in.
str	Text to position.

Returns

X-offset for a call to DrawTextLine to make the text aligned, or 0 if the text overflows.

CalcTextHeight()

int GUIFont::CalcTextHeight	(	std::string_view	str,
		int	width,
		int	x
	)

Parameters

str	Text to check.
width	Width of the window that the text should fit into.
x	Where does the text start relative to the window's left border?

Returns

Wrapped text height, in pixels.

CreateFontTex()

DrawCreditsEntry()

void GUIFont::DrawCreditsEntry	(	GUIFont *	pSecondFont,
		int	uFrameX,
		int	uFrameY,
		unsigned int	w,
		unsigned int	h,
		Color	firstColor,
		Color	secondColor,
		Color	shadowColor,
		std::string_view	pString,
		GraphicsImage *	image
	)

DrawText()

void GUIFont::DrawText	(	GUIWindow *	window,
		Pointi	position,
		Color	color,
		std::string_view	text,
		int	maxHeight,
		Color	shadowColor
	)

DrawTextInRect()

int GUIFont::DrawTextInRect	(	GUIWindow *	window,
		Pointi	position,
		Color	color,
		std::string_view	text,
		int	rect_width,
		int	reverse_text
	)

DrawTextLine()

Color GUIFont::DrawTextLine	(	std::string_view	text,
		Color	startColor,
		Color	defaultColor,
		Pointi	position
	)

Draws a single line of text. If provided text has more than a single line, only the 1st line is drawn.

Parameters

text	Input line of text.
startColor	Color that the text should be started to be drawn with - this allows feeding in the color returned from the previous call to maintain correct color when the text is split into multiple lines.
defaultColor	The color that the text should return to on hitting a default color tag.
position	Position to draw the text line at.

Returns

Color that was used to draw text at the end of the line.

DrawTextLineToBuff()

void GUIFont::DrawTextLineToBuff ( Color  color, Color  shadowColor, Color *  uX_buff_pos, std::string_view  text, int  line_width  )

private

FitTwoFontStringINWindow()

std::string GUIFont::FitTwoFontStringINWindow ( std::string_view  inString, GUIFont *  pFontSecond, GUIWindow *  pWindow, int  startPixlOff, bool  return_on_carriage = false  )

private

GetHeight()

int GUIFont::GetHeight

(

)

const

GetLineWidth()

int GUIFont::GetLineWidth

(

std::string_view

str

)

Parameters

str	Text to check.

Returns

Width of the first line of str, in pixels. Note that \t counts as a line break as it essentially starts a new table column.

GetPageText()

std::string GUIFont::GetPageText	(	std::string_view	str,
		Sizei	pageSize,
		int	x,
		int	page
	)

Parameters

str	Multipage text to page-wrap.
pageSize	Size of a single page, in pixels.
x	Where does the text start relative to the page's left border?
page	Page number to get the text for, starts at 0.

Returns

Text at the given page. Note that this function doesn't cut the text's tail.

GetStringHeight2()

int GUIFont::GetStringHeight2	(	GUIFont *	secondFont,
		std::string_view	text_str,
		GUIWindow *	pWindow,
		int	startX,
		int	a6
	)
