FBB::Xpointer(3bobcat)
NAME
FBB::Xpointer - Sets the location of the X-windows pointer
SYNOPSIS
#include <bobcat/xpointer>
Linking option: -lX11 -lbobcat
DESCRIPTION
This class allows programs running within the X-graphical environment
to set and retrieve the X-windows pointer location.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in
this man-page, are defined in the namespace FBB.
INHERITS FROM
CONSTRUCTORS
- o Xpointer():
- The default constructor. Connects to the Display. throws an Errno exception if the display cannot be opened. With multiple Xpointer objects, the connection to the display is opened only once.
- This constructor throws an Errno exception if it could not connect to the Display. The copy constructor is available.
MEMBER FUNCTIONS
- 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.
- o void verify() const:
- Obsoleted, will be removed in a future Bobcat release.
EXAMPLE
#include <iostream>
#include <string>
#include <bobcat/xpointer>
using namespace FBB;
- int main()
try
{ - Xpointer xpointer;
xpointer.verify(); - if (!xpointer.set(100, 200))
throw string("Set pointer failed");
- int x;
int y; - if (!xpointer.get(&x, &y))
throw string("Get pointer failed");
- cout << "Pointer now at " << x << ", " << y << endl;
- return 0;
- }
catch (string msg)
{ - cout << msg << endl;
return 1; - }
