Detailed Description

Rectangle shaped text block.

This class represents a drawable text block that supports multi-line text with automatic word wrapping. Text can contain newline characters (\n) for manual line breaks, or use automatic word wrapping based on a maximum width.

Note

Set the font using setFont() before calling setText() with a maxWidth parameter for correct text wrapping behavior.

Example usage:

jngl::Text text;
text.setFont(myFont);
text.setText("Hello World!\nThis is a very long line.", 150);
text.setAlign(jngl::Alignment::CENTER);
text.draw();

Member Function Documentation

setText()

void setText	(	const std::string &	,
		double	maxWidth = std::numeric_limits< double >::max() )

The text to display (may contain \n newlines)

Parameters

maxWidth

Maximum width of the text block in pixels. If the text exceeds this width, it will be wrapped at word boundaries to fit within the specified width. Defaults to no limit (std::numeric_limits<double>::max()).

Note

In order for this to work correctly, call this after setFont.

step()

void step ( )

overridevirtual

Does nothing.

Implements Drawable.

draw()

void draw ( ) const

overridevirtual

Simply draws the Text object.

Implements Drawable.
