The Angle GUI class is used to enter an angle. Angle can be toggled between radians and degrees by clicking on the Rad/Deg button or by using the appropriate functions. Needs to be added to the dialog widget to be used.

Constructs an angle gui widget.

•  local angle1 = gui.Angle("Angle1") 

Used to get the current value of the angle widget or set it to a desired value.

Note:- Always returns and expects the value to be in RADIANS . If the current display mode is in degrees, the angle is converted to degrees and displayed. When retrieving the mode dosen't matter, always returns in radians.

•  local val = angle1:value() 

•  angle1:setValue(1.56) 

Used to switch the display mode to degrees, if the value is in radians it is automatically converted and shown in degrees.

•  angle1:toDegrees() 

Used to switch the display mode to radians, if the value is in degrees it is automatically converted and shown in radians.

•  angle1:toRadians() 

Add a finish callback which is called when the user presses enter after entering the angle or clicks somewhere else and the input gui loses focus. This is different from the dialog widget finish callback.

•  angle1:addFinishCallback(function() message("Finished typing angle") end) 

Add an on change callback which is called when the user types anything i.e. on any change to the input.

•  angle1:addOnChangeCallback(function() message(tostring(angle1:value())) end)
