#Mouse Gestures
-#Version 0.0.0 ALPHA
+#Version 0.0.1
#By Daniel Pozmanter
#drpython@bluebottle.com
#This is a class to add Mouse Gestures to a program.
#It can be used in two ways:
-#
-#1. Automatic:
-# Automatically runs mouse gestures.
-# You need to set the gestures, and their associated actions,
-# as well as the Mouse Button/Modifiers to use.
#
-# (Mouse Buttons are set in init)
+#1. Automatic:
+# Automatically runs mouse gestures.
+# You need to set the gestures, and their associated actions,
+# as well as the Mouse Button/Modifiers to use.
#
#2. Manual:
-# Same as above, but you do not need to set the mouse button/modifiers.
-# You can launch this from events as you wish.
+# Same as above, but you do not need to set the mouse button/modifiers.
+# You can launch this from events as you wish.
#
#An example is provided in the demo.
#The parent window is where the mouse events will be recorded.
#Start() starts recording mouse movement.
#End() stops the recording, compiles all the gestures into a list,
#and looks through the registered gestures to find a match.
-#The first matchs associated action is then run.
+#The first matchs associated action is then run.
#The marginoferror is how much to forgive when calculating movement:
#If the margin is 25, then movement less than 25 pixels will not be detected.
#is not greater than twice the lesser, only the grater value
#is counted.
-#ToDo:
-#Add in modifier code (Ctrl, Alt, etc).
+#In automatic mode, EVT_MOUSE_EVENTS is used.
+#This allows the user to change the mouse button/modifiers at runtime.
+
+###########################################
+
+'''
+Changelog:
+0.0.1: Treats a mouse leaving event as mouse up.
+ (Bug Report, Thanks Peter Damoc).
+
+
+0.0.0: Initial Release.
+'''
+
+###########################################
+#ToDo:
-#SetGestureLine(wx.Colour(), int width)
+#Fully Implement Manual Mode
#Add "Ends With": AddGestureEndsWith(self, gesture, action, args)
#Add "Starts With": AddGestuteStartsWith(self, gesture, action, args)
-#At the moment, the mouse button can only be set at startup.
-#I could use UnBind, but this may limit the wxPython version being used,
-#and, what if the user has other events bound?
-#So I think, if the user wants to change the mouse button at runtime,
-#the best solution is to use manual mode.
-
+#For better control of when the gesture starts and stops,
+#use manual mode.
+#At the moment, you need to Bind the OnMouseMotion event if you want to use
+#manual mode.
