Member Function Documentation

◆ GetSubStringForLine()

SubStringIterator SDL::TextBase::GetSubStringForLine ( int line ) const

Get iterator to substring of a text object that contains the given line.

If line is greater than or equal to text->num_lines this will return an iterator equal to end().

Parameters

line	a zero-based line index, in the range [0 .. text->num_lines-1].

Returns: iterator on success or false on failure; call GetError() for more information.

Thread safety:: This function should be called on the thread that created the text.

Since: This function is available since SDL_ttf 3.0.0.

◆ GetSubStringForPoint()

SubStringIterator SDL::TextBase::GetSubStringForPoint ( Point p ) const

Get the portion of a text string that is closest to a point.

This will return the closest substring of text to the given point.

Parameters

p	the coordinates relative to the top-left side of the text, may be outside the bounds of the text area.

Returns: the iterator on success or false on failure; call GetError() for more information.

Thread safety:: This function should be called on the thread that created the text.

Since: This function is available since SDL_ttf 3.0.0.

◆ GetSubStrings()

OwnArray< SubString * > SDL::TextBase::GetSubStrings ( ) const

inline

Get all substrings of a text object.

Returns: a nullptr terminated array of substring pointers or nullptr on failure; call GetError() for more information.

Thread safety:: This function should be called on the thread that created the text.

Since: This function is available since SDL_ttf 3.0.0.

The documentation for this struct was generated from the following file:
