FBB::Xpointer - Sets the location of the X-windows pointer
#include <bobcat/xpointer>
Linking option: -lbobcat -lX11
This class allows programs running within the X-graphical
environment to set and retrieve the X-windows pointer location.
FBB
All constructors, members, operators and manipulators, mentioned in this
man-page, are defined in the namespace FBB.
- o
- Xpointer():
The default constructor. Connects to the Display. throws an Exception
exception if the display cannot be opened. With multiple Xpointer
objects, the connection to the display is opened only once.
- This constructor throws an Exception exception if it could not
connect to the Display. The copy constructor is available.
- o
- bool get(int *x, int *y) const:
Returns in its arguments the currnet pointer coordinates relative to the
root-window. On success true is returned; false is returned
if the pointer could not be moved.
- o
- bool set(int x, int y) const:
Sets the pointer to a location whose pixel coordinates are given with
respect to the root-window. A negative x-coordinate is measured from the
right screen-margin of the root window (going left), a negative
y-coordinate is measured from the bottom screen-margin of the root window
(going up). On success true is returned; false is returned
if the pointer could not be moved.
