SpinGadget()

Syntax

Result = SpinGadget(#Gadget, x, y, Width, Height, Minimum, Maximum [, Flags])

Parameters

#Gadget	A number to identify the new gadget. #PB_Any can be used to auto-generate this number.
x, y, Width, Height	The position and dimensions of the new gadget.
Minimum, Maximum	The minimum and maximum values for the gadget.
Flags (optional)	Flags to modify the gadget behavior. It can be a combination of the following values: #PB_Spin_ReadOnly : The StringGadget is not editable, the number is only changeable by the arrows (not available on Linux) #PB_Spin_Numeric : The SpinGadget will automatically update the text with value of the state, so SetGadgetText() is not needed.
