Hi all,
I am trying to get the width of a text in Quartz through declares. As
per the tech note <http://developer.apple.com/qa/qa2001/qa1051.html>, it
is achieved by storing the current text position p1.x, drawing the text
in invisible mode, and taking the difference between the new text
position p2 and the old, that is textWidth = (p2.X - p1.X)
The problem is with the function used to get the current text position:
CGPoint CGContextGetTextPosition (
CGContextRef context
);
which returns a CGPoint.
Starting from Seth's great articles on ResExcellence, I translated it to:
Declare Function CGContextGetTextPosition Lib "Carbon" (CGContextRef as
Integer) As CGPoint
where CGPoint is a 8-byte structure.
Nothing of what I tried so far seems to work as return type, CGPoint,
Memoryblock, Ptr, etc.
Any help on this would be much, much appreciated.
BTW: Thanks so much to Real for the Graphics.Handle types and for
CFString and CString. Little gems.
