This seems to work correctly, but it is likely that someone who remembers their high school math could make it _much_ more efficient (I just hacked away 'till it worked). -Carl git-svn-id: file:///fltk/svn/fltk/trunk@376 ea41ed52-d2ee-0310-a9c1-e6b18d33e121 --- documentation/Fl_Dial.html | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'documentation/Fl_Dial.html') diff --git a/documentation/Fl_Dial.html b/documentation/Fl_Dial.html index ff70b6db1..a320d7df5 100644 --- a/documentation/Fl_Dial.html +++ b/documentation/Fl_Dial.html @@ -34,7 +34,12 @@ and label string.

void Fl_Dial::angles(short a, short b)

Sets the angles used for the minimum and maximum values. By default -these are 0 and 360, respectively. +these are 225 and 135, respectively. (0 degrees is straight up and the +angles progress clockwise.) The angles specified should be greater than +or equal to 0 and less than 360. The progress of the dial always starts at +the minimum angle and progresses clockwise to the maximum angle. Currently, +counter-clockwise progression is not supported (but user code can always +use 1/value()).
