# get_angle

## Description:

Returns the relative angle from `event1`

to `event2`

.

The relative angle is the angle between the X axis and the line through both events' positions. The rotation direction for positive angles is from the positive X axis towards the positive Y axis.

This assumes that both events have X/Y information. If not, this function returns false.

## Parameters:

event2 |
second `GdkEvent` |

angle |
return location for the relative angle between both events |

event1 |
first `GdkEvent` |

## Returns:

true if the angle could be calculated. |
