Function Documentation

HorizontalAlignOffset()

int32_t tachyon::HorizontalAlignOffset ( TextAlign horizontalAlignment, int32_t boxWidth, int32_t contentWidth )

inline

#include <gui_core/text/gui_icon_text_placement.h>

X offset, in pixels, of contentWidth content aligned inside a boxWidth box.

Vertical values map as skribidi does: Top acts as left, Bottom as right.

VerticalAlignOffset()

int32_t tachyon::VerticalAlignOffset ( TextAlign verticalAlignment, int32_t boxHeight, int32_t contentHeight )

inline

#include <gui_core/text/gui_icon_text_placement.h>

ComputeIconTextPlacement()

IconTextPlacement tachyon::ComputeIconTextPlacement ( const IntRect & rect, int32_t textWidth, int32_t textHeight, const IconMeasurement & iconMeasurement, IconSide iconSide, int32_t iconTextGap, TextAlign horizontalAlignment, TextAlign verticalAlignment = TextAlign::Start )

inline

#include <gui_core/text/gui_icon_text_placement.h>

IconAwareLayoutMaxWidth()

int32_t tachyon::IconAwareLayoutMaxWidth ( int32_t rectWidth, const IconMeasurement & iconMeasurement, IconSide iconSide, int32_t iconTextGap, bool hasIcon )

inline

#include <gui_core/text/gui_icon_text_placement.h>

The max width to lay text out in: rectWidth minus the icon and gap for a Left / Right icon, so text-align can't reach into the icon area; rectWidth otherwise.

FormatNumber()

std::string tachyon::FormatNumber	(	NumericType	type,
		const NumericValue &	value )

#include <gui_core/text/gui_numeric_text.h>

value as text; floats use up to 9 significant digits, NaN and infinities spelled out.

ParseNumber()

bool tachyon::ParseNumber	(	std::string_view	text,
		NumericType	type,
		NumericValue &	outValue )

#include <gui_core/text/gui_numeric_text.h>

The whole text as a number of type: in range and, for floats, finite.

FilterNumberText()

bool tachyon::FilterNumberText	(	NumericType	type,
		std::string &	text )

#include <gui_core/text/gui_numeric_text.h>

Strips what a number of type can't hold (letters, a second dot, ...).

Partial forms that can still be finished ("-", "1e-") stay. True if Text changed.

IsNumberCharacter()

bool tachyon::IsNumberCharacter	(	NumericType	type,
		uint32_t	codepoint )

#include <gui_core/text/gui_numeric_text.h>

Whether codepoint can be typed into a number of type.
