| class MTmSource : public MTmCustom |
WARNING: this Class is for internal use ONLY. Compatibility is not guaranteed in future releases. MTmSource is an interface class that must be implemented by users of CTmTextLayout to provide text content and attributes. MTmSource is derived from MTmCustom, which contains the functions to customise the layout and display, so that this can be done in CTmText without affecting the content.

| TInt | DocumentLength | ( | ) | const [pure virtual] |
Return the length of the document in characters.
| MGraphicsDeviceMap & | FormatDevice | ( | ) | const [pure virtual] |
Return the device used to format the text.

| void | GetParagraphFormatL | ( | TInt | aPos, |
| RTmParFormat & | aFormat | |||
| ) | const [pure virtual] | |||
Return the paragraph format of the paragraph containing aPos. End-of-paragraph characters belong to the preceding paragraph.
| TInt aPos | |
| RTmParFormat & aFormat |
| IMPORT_C TInt | GetPictureSizeInTwipsL | ( | TInt | aPos, |

| void | GetText | ( | TInt | aPos, |
| TPtrC & | aText, | |||
| TTmCharFormat & | aFormat | |||
| ) | const [pure virtual] | |||
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.
| TInt aPos | |
| TPtrC & aText | |
| TTmCharFormat & aFormat |
| MGraphicsDeviceMap & | InterpretDevice | ( | ) | const [pure virtual] |
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.
| IMPORT_C TBool | PageBreakInRange | ( | TInt | aStartPos, |
| TInt | aEndPos | |||
| ) | const [virtual] | |||
| TInt | ParagraphStart | ( | TInt | aPos | ) | const [pure virtual] |
Return the document position of the start of the paragraph containing aPos. End-of-paragraph characters belong to the preceding paragraph.
| TInt aPos |
