xclick — wait for a mouse click
[c_i,c_x,c_y,c_w,c_m]=xclick([flag])
| c_i | : integer, mouse button number. |
| c_x,c_y | : real scalars, position of the mouse. |
| c_w | : integer, window number. |
| c_m | : string, menu callback. |
| flag | : integer. If present, the click event queue is not cleared when entering xclick. |
xclick waits for a mouse click in the graphics window.
If it is called with 3 left hand side arguments, it waits for a mouse click in the current graphics window.
If it is called with 4 or 5 left hand side arguments, it waits for a mouse click in any graphics window.
The returned values are described below.
| c_i | : an integer which gives the number of the mouse button that was pressed 0, 1 or 2 (for left, middle and right) or -1 in case of problems with xclick. |
| c_x,c_y | : the coordinates of the position of the mouse click in the current graphics scale. |
| c_w | : the window number where the click has occurred. |
| c_m | : string associated with a dynamic menu. If xclick returns due to a click on a menu, c_i, c_x, c_y, and c_w take arbitrary values. |
xclick can return the message "Can't grab the pointer" if the graphics window is iconified when calling it.
