Return the length of the document in characters.

Return the device used to format the text.

Return the paragraph format of the paragraph containing aPos. End-of-paragraph characters belong to the preceding paragraph.

A static function to expose the standard line breaking system for use on plain text, mainly so that UIKON can use it for messages.

It finds the last feasible line break in the range aMinBreakPos...aMaxBreakPos within aText, and the start of the next line, which may be after aMaxBreakPos (because aMaxBreakPos may be in a run of spaces or before a line or paragraph separator).

The text passed in is the maximum that will fit the required line width; in other words, it has already been measured. The best way to do this is to use CFont::MeasureText and specify a TMeasureTextInput parameter with TMeasureTextInput::iMaxAdvance to the line width; TMeasureTextOutput::iChars gives the maximum length that will fit the line.

Bidirectional reformatting should be done after the break position is found.

Limitations:

Forced line breaks, which may be caused by CR, LF, FF, combinations of these, U+2028, and U+2029, are ignored, the purpose of the function being to break some text that is already known to be too wide for a certain measure. Dictionary-based line breaking for Thai is not available. Use zero-width spaces to allow line breaks in Thai.

This function cannot leave because MTmSource::GetLineBreakL cannot leave unless the implementation of PictureL can leave, and here the default MTmSource::PictureL, which does not leave, is called.

Return at least one character of text, but preferably as many as possible, starting at aPos. Put its character format in aFormat. The text must be a run of characters sharing the same character format.

Return the device used to draw the text and when converting between x-y coordinates and document positions. If the formatting and interpreting devices are different, text is scaled appropriately when it is drawn; this allows text to be formatted for printer fonts and displayed on the screen, giving a wysiwyg print preview.

Return the end of the paragraph - after the paragraph separator if any.

Return the document position of the start of the paragraph containing aPos. End-of-paragraph characters belong to the preceding paragraph.

The default function to get a picture; override this if there are pictures in the document.
