NAME
FBB::Xpointer - Sets the location of the X-windows pointerSYNOPSIS
#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
FBBAll 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. - The proper completion of this constructor should be checked by calling the Xpointer::verify() member (see below). 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:
This operator throws an Errno exception if the Xpointer constructor could not connect to the Display. It should be called before using any other Xpointer member (not required after using the copy constructor).
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; }
