+ A platform-independent image class. An image can be created from
+ data, or using `wx.Bitmap.ConvertToImage`, or loaded from a file in a
+ variety of formats. Functions are available to set and get image
+ bits, so it can be used for basic image manipulation.
+
+ A wx.Image cannot be drawn directly to a `wx.DC`. Instead, a
+ platform-specific `wx.Bitmap` object must be created from it using the
+ `wx.BitmapFromImage` constructor. This bitmap can then be drawn in a
+ device context, using `wx.DC.DrawBitmap`.
+
+ One colour value of the image may be used as a mask colour which will
+ lead to the automatic creation of a `wx.Mask` object associated to the
+ bitmap object.
+
+ wx.Image supports alpha channel data, that is in addition to a byte
+ for the red, green and blue colour components for each pixel it also
+ stores a byte representing the pixel opacity. An alpha value of 0
+ corresponds to a transparent pixel (null opacity) while a value of 255
+ means that the pixel is 100% opaque.
+
+ Unlike RGB data, not all images have an alpha channel and before using
+ `GetAlpha` you should check if this image contains an alpha channel
+ with `HasAlpha`. Note that currently only images loaded from PNG files
+ with transparency information will have an alpha channel.

class KeyEvent(Event):
- """Proxy of C++ KeyEvent class"""
+ """
+ This event class contains information about keypress and character
+ events. These events are only sent to the widget that currently has
+ the keyboard focus.
+
+ Notice that there are three different kinds of keyboard events in
+ wxWidgets: key down and up events and char events. The difference
+ between the first two is clear - the first corresponds to a key press
+ and the second to a key release - otherwise they are identical. Just
+ note that if the key is maintained in a pressed state you will
+ typically get a lot of (automatically generated) down events but only
+ one up so it is wrong to assume that there is one up event
+ corresponding to each down one.
+
+ Both key events provide untranslated key codes while the char event
+ carries the translated one. The untranslated code for alphanumeric
+ keys is always an upper case value. For the other keys it is one of
+ WXK_XXX values from the keycodes table. The translated key is, in
+ general, the character the user expects to appear as the result of the
+ key combination when typing the text into a text entry zone, for
+ example.
+
+ A few examples to clarify this (all assume that CAPS LOCK is unpressed
+ and the standard US keyboard): when the 'A' key is pressed, the key
+ down event key code is equal to ASCII A == 65. But the char event key
+ code is ASCII a == 97. On the other hand, if you press both SHIFT and
+ 'A' keys simultaneously , the key code in key down event will still be
+ just 'A' while the char event key code parameter will now be 'A' as
+ well.
+
+ Although in this simple case it is clear that the correct key code
+ could be found in the key down event handler by checking the value
+ returned by `ShiftDown`, in general you should use EVT_CHAR for this
+ as for non alphanumeric keys or non-US keyboard layouts the
+ translation is keyboard-layout dependent and can only be done properly
+ by the system itself.
+
+ Another kind of translation is done when the control key is pressed:
+ for example, for CTRL-A key press the key down event still carries the
+ same key code 'A' as usual but the char event will have key code of 1,
+ the ASCII value of this key combination.
+
+ You may discover how the other keys on your system behave
+ interactively by running the KeyEvents sample in the wxPython demo and
+ pressing some keys while the blue box at the top has the keyboard
+ focus.
+
+ **Note**: If a key down event is caught and the event handler does not
+ call event.Skip() then the coresponding char event will not
+ happen. This is by design and enables the programs that handle both
+ types of events to be a bit simpler.
+
+ **Note for Windows programmers**: The key and char events in wxWidgets
+ are similar to but slightly different from Windows WM_KEYDOWN and
+ WM_CHAR events. In particular, Alt-x combination will generate a char
+ event in wxWidgets (unless it is used as an accelerator).
+
+ **Tip**: be sure to call event.Skip() for events that you don't
+ process in key event function, otherwise menu shortcuts may cease to
+ work under Windows.

class UpdateUIEvent(CommandEvent):
- """Proxy of C++ UpdateUIEvent class"""
+ """
+ This class is used for EVT_UPDATE_UI pseudo-events which are sent by
+ wxWidgets to give an application the chance to update various user
+ interface elements.
+
+ Without update UI events, an application has to work hard to
+ check/uncheck, enable/disable, and set the text for elements such as
+ menu items and toolbar buttons. The code for doing this has to be
+ mixed up with the code that is invoked when an action is invoked for a
+ menu item or button.
+
+ With update UI events, you define an event handler to look at the
+ state of the application and change UI elements accordingly. wxWidgets
+ will call your handler functions in idle time, so you don't have to
+ worry where to call this code. In addition to being a clearer and more
+ declarative method, it also means you don't have to worry whether
+ you're updating a toolbar or menubar identifier. The same handler can
+ update a menu item and toolbar button, if the ID values are the same.
+
+ Instead of directly manipulating the menu or button, you call
+ functions in the event object, such as `Check`. wxWidgets will
+ determine whether such a call has been made, and which UI element to
+ update.
+
+ These events will work for popup menus as well as menubars. Just
+ before a menu is popped up, `wx.Menu.UpdateUI` is called to process
+ any UI events for the window that owns the menu.
+
+ If you find that the overhead of UI update processing is affecting
+ your application, you can do one or both of the following:
+
+ 1. Call `wx.UpdateUIEvent.SetMode` with a value of
+ wx.UPDATE_UI_PROCESS_SPECIFIED, and set the extra style
+ wx.WS_EX_PROCESS_UPDATE_EVENTS for every window that should
+ receive update events. No other windows will receive update
+ events.
+
+ 2. Call `wx.UpdateUIEvent.SetUpdateInterval` with a millisecond
+ value to set the delay between updates. You may need to call
+ `wx.Window.UpdateWindowUI` at critical points, for example when
+ a dialog is about to be shown, in case the user sees a slight
+ delay before windows are updated.
+
+ Note that although events are sent in idle time, defining a EVT_IDLE
+ handler for a window does not affect this because the events are sent
+ from an internal idle handler.
+
+ wxWidgets tries to optimize update events on some platforms. On
+ Windows and GTK+, events for menubar items are only sent when the menu
+ is about to be shown, and not in idle time.
