XTranslateCoordinates(3X) — X Version 11
NAME
XTranslateCoordinates − translate window coordinates
SYNTAX
int XTranslateCoordinates(display, src_w, dest_w, src_x, src_y, dest_x_return,
dest_y_return, child_return)
Display ∗display;
Window src_w, dest_w;
int src_x, src_y;
int ∗dest_x_return, ∗dest_y_return;
Window ∗child_return;
ARGUMENTS
child_returnReturns the child if the coordinates are contained in a mapped child of the destination window.
dest_wSpecifies the window ID of the destination window.
dest_x_return
dest_y_return
Returns the x and y coordinates within the destination window.
displaySpecifies the connection to the X server.
src_wSpecifies the window ID of the source window.
src_x
src_ySpecify the x and y coordinates within the source window.
DESCRIPTION
The XTranslateCoordinates function takes the src_x and src_y coordinates within the source window relative to the source window’s origin and returns these coordinates to dest_x_return and dest_y_return relative to the destination window’s origin. If XTranslateCoordinates returns zero, src_w and dest_w are on different screens, and dest_x_return and dest_y_return are zero. If the coordinates are contained in a mapped child of dest_w, that child is returned to the child argument. .PN XTranslateCoordinates can generate a BadWindow error.
DIAGNOSTICS
BadWindow A value for a Window argument does not name a defined Window.
