- Notice that events are usually created by wxWidgets itself and creating
- e.g. a wxPaintEvent in your code and sending it to e.g. a wxTextCtrl
- will not usually affect it at all as native controls have no specific
- knowledge about wxWidgets events. However you may construct objects of
- specific types and pass them to wxEvtHandler::ProcessEvent() if you
- want to create your own custom control and want to process its events
- in the same manner as the standard ones.
-
- Also please notice that the order of parameters in this constructor is
- different from almost all the derived classes which specify the event
- type as the first argument.
-
- @param id
- The identifier of the object (window, timer, ...) which generated
- this event.
- @param eventType
- The unique type of event, e.g. wxEVT_PAINT, wxEVT_SIZE or
- wxEVT_COMMAND_BUTTON_CLICKED.

- All wxWidgets events fully implement this method, but any derived events

- documentation by ensuring that the @a event object is not used by the

- fields of this object are used by it, notably any wxString members of

@class wxKeyEvent
- This event class contains information about keypress (character) events.
-
- 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 @c WXK_XXX values
- from the @ref page_keycodes.
- 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 @c 'A' key is pressed, the key down
- event key code is equal to @c ASCII A == 65. But the char event key code
- is @c ASCII a == 97. On the other hand, if you press both SHIFT and
- @c 'A' keys simultaneously , the key code in key down event will still be
- just @c 'A' while the char event key code parameter will now be @c '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
- wxKeyEvent::ShiftDown(), in general you should use @c EVT_CHAR for this as
- for non-alphanumeric keys 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 @c '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 @ref page_samples_text wxWidgets sample and pressing some keys
- in any of the text controls shown in it.
-
- @b Tip: be sure to call @c event.Skip() for events that you don't process in
- key event function, otherwise menu shortcuts may cease to work under Windows.
+ This event class contains information about key press and release events.
+
+ The main information carried by this event is the key being pressed or
+ released. It can be accessed using either GetKeyCode() function or
+ GetUnicodeKey(). For the printable characters, the latter should be used as
+ it works for any keys, including non-Latin-1 characters that can be entered
+ when using national keyboard layouts. GetKeyCode() should be used to handle
+ special characters (such as cursor arrows keys or @c HOME or @c INS and so
+ on) which correspond to ::wxKeyCode enum elements above the @c WXK_START
+ constant. While GetKeyCode() also returns the character code for Latin-1
+ keys for compatibility, it doesn't work for Unicode characters in general
+ and will return @c WXK_NONE for any non-Latin-1 ones. For this reason, it's
+ recommended to always use GetUnicodeKey() and only fall back to GetKeyCode()
+ if GetUnicodeKey() returned @c WXK_NONE meaning that the event corresponds
+ to a non-printable special keys.
+
+ While both of these functions can be used with the events of @c
+ wxEVT_KEY_DOWN, @c wxEVT_KEY_UP and @c wxEVT_CHAR types, the values
+ returned by them are different for the first two events and the last one.
+ For the latter, the key returned corresponds to the character that would
+ appear in e.g. a text zone if the user pressed the key in it. As such, its
+ value depends on the current state of the Shift key and, for the letters,
+ on the state of Caps Lock modifier. For example, if @c A key is pressed
+ without Shift being held down, wxKeyEvent of type @c wxEVT_CHAR generated
+ for this key press will return (from either GetKeyCode() or GetUnicodeKey()
+ as their meanings coincide for ASCII characters) key code of 97
+ corresponding the ASCII value of @c a. And if the same key is pressed but
+ with Shift being held (or Caps Lock being active), then the key could would
+ be 65, i.e. ASCII value of capital @c A.
+
+ However for the key down and up events the returned key code will instead
+ be @c A independently of the state of the modifier keys i.e. it depends
+ only on physical key being pressed and is not translated to its logical
+ representation using the current keyboard state. Such untranslated key
+ codes are defined as follows:
+ - For the letters they correspond to the @e upper case value of the
+ letter.
+ - For the other alphanumeric keys (e.g. @c 7 or @c +), the untranslated
+ key code corresponds to the character produced by the key when it is
+ pressed without Shift. E.g. in standard US keyboard layout the
+ untranslated key code for the key @c =/+ in the upper right corner of
+ the keyboard is 61 which is the ASCII value of @c =.
+ - For the rest of the keys (i.e. special non-printable keys) it is the
+ same as the normal key code as no translation is used anyhow.
+
+ Notice that the first rule applies to all Unicode letters, not just the
+ usual Latin-1 ones. However for non-Latin-1 letters only GetUnicodeKey()
+ can be used to retrieve the key code as GetKeyCode() just returns @c
+ WXK_NONE in this case.
+
+ To summarize: you should handle @c wxEVT_CHAR if you need the translated
+ key and @c wxEVT_KEY_DOWN if you only need the value of the key itself,
+ independent of the current keyboard state.
+
+ @note Not all key down events may be generated by the user. As an example,
+ @c wxEVT_KEY_DOWN with @c = key code can be generated using the
+ standard US keyboard layout but not using the German one because the @c
+ = key corresponds to Shift-0 key combination in this layout and the key
+ code for it is @c 0, not @c =. Because of this you should avoid
+ requiring your users to type key events that might be impossible to
+ enter on their keyboard.
+
+
+ Another difference between key and char events is that another kind of
+ translation is done for the latter ones when the Control key is pressed:
+ char events for ASCII letters in this case carry codes corresponding to the
+ ASCII value of Ctrl-Latter, i.e. 1 for Ctrl-A, 2 for Ctrl-B and so on until
+ 26 for Ctrl-Z. This is convenient for terminal-like applications and can be
+ completely ignored by all the other ones (if you need to handle Ctrl-A it
+ is probably a better idea to use the key event rather than the char one).
+ Notice that currently no translation is done for the presses of @c [, @c
+ \\, @c ], @c ^ and @c _ keys which might be mapped to ASCII values from 27
+ to 31.
+ Since version 2.9.2, the enum values @c WXK_CONTROL_A - @c WXK_CONTROL_Z
+ can be used instead of the non-descriptive constant values 1-26.
+
+ Finally, modifier keys only generate key events but no char events at all.
+ The modifiers keys are @c WXK_SHIFT, @c WXK_CONTROL, @c WXK_ALT and various
+ @c WXK_WINDOWS_XXX from ::wxKeyCode enum.
+
+ Modifier keys events are special in one additional aspect: usually the
+ keyboard state associated with a key press is well defined, e.g.
+ wxKeyboardState::ShiftDown() returns @c true only if the Shift key was held
+ pressed when the key that generated this event itself was pressed. There is
+ an ambiguity for the key press events for Shift key itself however. By
+ convention, it is considered to be already pressed when it is pressed and
+ already released when it is released. In other words, @c wxEVT_KEY_DOWN
+ event for the Shift key itself will have @c wxMOD_SHIFT in GetModifiers()
+ and ShiftDown() will return true while the @c wxEVT_KEY_UP event for Shift
+ itself will not have @c wxMOD_SHIFT in its modifiers and ShiftDown() will
+ return false.
+
+
+ @b Tip: You may discover the key codes and modifiers generated by all the
+ keys on your system interactively by running the @ref
+ page_samples_keyboard wxWidgets sample and pressing some keys in it.
@note If a key down (@c EVT_KEY_DOWN) event is caught and the event handler
does not call @c event.Skip() then the corresponding char event
- (@c EVT_CHAR) will not happen.
- This is by design and enables the programs that handle both types of
- events to be a bit simpler.
+ (@c EVT_CHAR) will not happen. This is by design and enables the
+ programs that handle both types of events to avoid processing the
+ same key twice. As a consequence, if you do not want to suppress the
+ @c wxEVT_CHAR events for the keys you handle, always call @c
+ event.Skip() in your @c wxEVT_KEY_DOWN handler. Not doing may also
+ prevent accelerators defined using this key from working.
+
+ @note If a key is maintained in a pressed state, you will typically get a
+ lot of (automatically generated) key down events but only one key up
+ one at the end when the key is released so it is wrong to assume that
+ there is one up event corresponding to each down one.
@note For Windows programmers: The key and char events in wxWidgets are
similar to but slightly different from Windows @c WM_KEYDOWN and
@c WM_CHAR events. In particular, Alt-x combination will generate a
- char event in wxWidgets (unless it is used as an accelerator).

+ is sent initially (if there is no focused window, this event is sent to
+ the wxApp global object). It is also generated before any other key
+ events and so gives the parent window an opportunity to modify the
+ keyboard handling of its children, e.g. it is used internally by
+ wxWidgets in some ports to intercept pressing Esc key in any child of a
+ dialog to close the dialog itself when it's pressed. By default, if
+ this event is handled, i.e. the handler doesn't call wxEvent::Skip(),
+ neither @c wxEVT_KEY_DOWN nor @c wxEVT_CHAR events will be generated
+ (although @c wxEVT_KEY_UP still will be), i.e. it replaces the normal
+ key events. However by calling the special DoAllowNextEvent() method
+ you can handle @c wxEVT_CHAR_HOOK and still allow normal events
+ generation. This is something that is rarely useful but can be required
+ if you need to prevent a parent @c wxEVT_CHAR_HOOK handler from running
+ without suppressing the normal key events. Finally notice that this
+ event is not generated when the mouse is captured as it is considered
+ that the window which has the capture should receive all the keyboard
+ events too without allowing its parent wxTopLevelWindow to interfere
+ with their processing.

A paint event is sent when a window's contents needs to be repainted.
- Please notice that in general it is impossible to change the drawing of a
- standard control (such as wxButton) and so you shouldn't attempt to handle
- paint events for them as even if it might work on some platforms, this is
- inherently not portable and won't work everywhere.
-
- @remarks
- Note that in a paint event handler, the application must always create a
- wxPaintDC object, even if you do not use it. Otherwise, under MS Windows,
- refreshing for this and other windows will go wrong.
- For example:
+ The handler of this event must create a wxPaintDC object and use it for
+ painting the window contents. For example:
@code
void MyWindow::OnPaint(wxPaintEvent& event)
{
DrawMyDocument(dc);
}
@endcode
+
+ Notice that you must @e not create other kinds of wxDC (e.g. wxClientDC or
+ wxWindowDC) in EVT_PAINT handlers and also don't create wxPaintDC outside
+ of this event handlers.
+
+
You can optimize painting by retrieving the rectangles that have been damaged
and only repainting these. The rectangles are in terms of the client area,
and are unscrolled, so you will need to do some calculations using the current
