Puts a Cancel button in the message box. Must be combined with
either @c wxOK or @c wxYES_NO.
@style{wxYES_NO}
- Puts Yes and No buttons in the message box. May be combined with
- @c wxCANCEL.
+ Puts Yes and No buttons in the message box. It is recommended to always
+ use @c wxCANCEL with this style as otherwise the message box won't have
+ a close button under wxMSW and the user will be forced to answer it.
+ @style{wxHELP}
+ Puts a Help button to the message box. This button can have special
+ appearance or be specially positioned if its label is not changed from
+ the default one. Notice that using this button is not supported when
+ showing a message box from non-main thread in wxOSX/Cocoa and it is not
+ supported in wxOSX/Carbon at all. @since 2.9.3.
@style{wxNO_DEFAULT}
Makes the "No" button default, can only be used with @c wxYES_NO.
@style{wxCANCEL_DEFAULT}
@style{wxOK_DEFAULT}
Makes the "OK" button default, this is the default behaviour and
this flag exists solely for symmetry with @c wxCANCEL_DEFAULT.
+ @style{wxICON_NONE}
+ Displays no icon in the dialog if possible (an icon might still be
+ displayed if the current platform mandates its use). This style may be
+ used to prevent the dialog from using the default icon based on @c
+ wxYES_NO presence as explained in @c wxICON_QUESTION and @c
+ wxICON_INFORMATION documentation below.
@style{wxICON_EXCLAMATION}
- Displays an exclamation mark symbol.
+ Displays an exclamation, or warning, icon in the dialog.
@style{wxICON_ERROR}
- Displays an error symbol.
+ Displays an error icon in the dialog.
@style{wxICON_HAND}
Displays an error symbol, this is a MSW-inspired synonym for @c wxICON_ERROR.
@style{wxICON_QUESTION}
Displays a question mark symbol. This icon is automatically used
with @c wxYES_NO so it's usually unnecessary to specify it explicitly.
+ This style is not supported for message dialogs under wxMSW when a task
+ dialog is used to implement them (i.e. when running under Windows Vista
+ or later) because <a href="http://msdn.microsoft.com/en-us/library/aa511273.aspx">Microsoft
+ guidelines</a> indicate that no icon should be used for routine
+ confirmations. If it is specified, no icon will be displayed.
@style{wxICON_INFORMATION}
Displays an information symbol. This icon is used by default if
@c wxYES_NO is not given so it is usually unnecessary to specify it
explicitly.
@style{wxSTAY_ON_TOP}
- Makes the message box stay on top of all other windows (currently
- implemented only under MSW).
+ Makes the message box stay on top of all other windows and not only
+ just its parent (currently implemented only under MSW and GTK).
+ @style{wxCENTRE}
+ Centre the message box on its parent or on the screen if parent is not
+ specified.
+ Setting this style under MSW makes no differences as the dialog is
+ always centered on the parent.

Also notice that this function is not currently available on all
platforms (although as of wxWidgets 2.9.0 it is implemented in all
major ports), so it may return @false to indicate that the labels
- couldn't be changed. If it returns @true (currently only under wxMac),
- the labels were set successfully. Typically, if the function was used
- successfully, the main dialog message may need to be changed, e.g.:
+ couldn't be changed. If it returns @true, the labels were set
+ successfully.
