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{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
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 (currently only implemented under MSW).
+ specified.
+ Setting this style under MSW makes no differences as the dialog is
+ always centered on the parent.
