NAME

XTranslateCoordinates - translate window coordinates  

SYNTAX

Bool XTranslateCoordinates(Display *display, Window src_w, dest_w, int src_x, int src_y, int *dest_x_return, int *dest_y_return, Window *child_return);

 

ARGUMENTS

child_return

Returns the child if the coordinates are contained in a mapped child of the destination window.

dest_w

Specifies the destination window.

dest_x_return

dest_y_return

Return the x and y coordinates within the destination window.

display

Specifies the connection to the X server.

src_w

Specifies the source window.

src_x

src_y

Specify the x and y coordinates within the source window.

 

DESCRIPTION

If XTranslateCoordinates returns True, it takes the src_x and src_y coordinates 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 False, 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 child_return. Otherwise, child_return is set to None.

XTranslateCoordinates can generate a BadWindow error.  

DIAGNOSTICS

BadWindow

A value for a Window argument does not name a defined Window.
