MGL_wmCoordGlobalToLocal
Converts between local and global coordinates.
Declaration
void MGLAPI MGL_wmCoordGlobalToLocal(
window_t *wnd,
int x,
int y,
int *xLocal,
int *yLocal)
Prototype In
mgraph.h
Parameters
wnd |
the window |
x |
X coordinate in global space |
y |
Y coordinate in global space |
xLocal |
variable to store X coordinate in local space |
yLocal |
variable to store X coordinate in local space |
Description
This function converts point expressed in global coordinates (i.e. relative to device context's upper left corner) into coordinates relative to given window's upper left corner.
wnd may be a window arbitrary deep in windows hierarchy, MGL_wmCoordGlobalToLocal descends the hierarchy recursively.
