GXComputeLineBreaks
int GXComputeLineBreaks(CDC* pDC, LPCTSTR sz, int nCount, LPRECT rc, UINT nFormat, int* LineBreaks, int* LineLengths, int nMaxBreaks);
pDC
Points to the device context.
sz
Points to the text to be drawn.
nCount
Specifies the size of the text in bytes. You should pass -1 for a zero-terminated string.
rc
Drawing rectangle.
nFormat
-
Format:
- DT_LEFTleft aligned
- DT_CENTERcentered
- DT_RIGHTright aligned
- DT_TOPtop aligned
- DT_VCENTERvertically centered
- DT_BOTTOMbottom aligned
DT_WORBREAKword break
LineBreaks
Pointer to an integer where the number of necessary line breaks will be returned. Must not be NULL.
LineLengths
Pointer to an array of integers where the line break positions will be returned.
nMaxBreaks
The size of the integer array.
Return Value
The number of line breaks.
Remarks
This method computes the line break positions for a given text so that it can draw into a given rectangle. GXDrawTextLikeMultiLineEdit calls this method to find out where to break the lines.
