A Chord is a region bounded by the intersection of an ellipse and a line segment. This function draws a chord
based on the coordinates the function receives. There are no Powerbuilder equivalents.
Global External Function:
FUNCTION boolean Chord(ulong hwnd,long x1,long y1,long x2,long y2,long r1, long r2, &
long r3, long r4) LIBRARY "Gdi32.dll"
Script:
boolean rtn
ulong l_handle, l_device
long lv[8]
l_handle = handle(w_main)
l_device = GetDC(l_handle)
// This can be done in one line: i.e. l_device = GetDC(handle(w_main))
lv[ ] = {5,5,200,200,0,0,200,300}
rtn = Chord(l_device, lv[1], lv[2], lv[3], lv[4], lv[5], lv[6], lv[7], lv[8])
