Fix wrong use of Doxygen grouping-related markup which somehow worked in older Doxygen versions, but doesn't work any longer. This fixes the problem with the "Functions by Category" pages being empty in the resulting HTML documentation and wrong documentation being shown for a bunch of wxString members. This is a combined cherry-pick of the following master commits: bd92523bc5 Fix use of Doxygen @addtogroup command 4c46e01b14 Remove stray Doxygen end group marker 8ac10d28f8 Fix all the other comments with Doxygen grouping commands too c0f1ecf263 Fix another unbalanced Doxygen grouping command after last commit See #22248, #22572.

@class wxMessageDialog
|
|
|
|
This class represents a dialog that shows a single or multi-line message,
|
|
with a choice of OK, Yes, No and Cancel buttons.
|
|
|
|
@beginStyleTable
|
|
@style{wxOK}
|
|
Puts an Ok button in the message box. May be combined with @c wxCANCEL.
|
|
@style{wxCANCEL}
|
|
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. 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.
|
|
Available since wxWidgets 2.9.3.
|
|
@style{wxNO_DEFAULT}
|
|
Makes the "No" button default, can only be used with @c wxYES_NO.
|
|
@style{wxCANCEL_DEFAULT}
|
|
Makes the "Cancel" button default, can only be used with @c wxCANCEL.
|
|
This style is currently not supported (and ignored) in wxOSX.
|
|
@style{wxYES_DEFAULT}
|
|
Makes the "Yes" button default, this is the default behaviour and
|
|
this flag exists solely for symmetry with @c wxNO_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_ERROR}
|
|
Displays an error icon in the dialog.
|
|
@style{wxICON_WARNING}
|
|
Displays a warning icon in the dialog. This style should be used for
|
|
informative warnings or, in combination with @c wxYES_NO or @c wxCANCEL,
|
|
for questions that have potentially serious consequences (caution
|
|
icon is used on macOS in this case).
|
|
@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="https://docs.microsoft.com/en-us/windows/desktop/uxguide/mess-confirm">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{wxICON_EXCLAMATION}
|
|
Alias for @c wxICON_WARNING.
|
|
@style{wxICON_HAND}
|
|
Alias for @c wxICON_ERROR.
|
|
@style{wxICON_AUTH_NEEDED}
|
|
Displays an authentication needed symbol. This style is only supported
|
|
for message dialogs under wxMSW when a task dialog is used to implement
|
|
them (i.e. when running under Windows Vista or later). In other cases
|
|
the default icon selection logic will be used. Note this can be
|
|
combined with other styles to provide a fallback. For instance, using
|
|
wxICON_AUTH_NEEDED | wxICON_QUESTION will show a shield symbol on
|
|
Windows Vista or above and a question symbol on other platforms.
|
|
Available since wxWidgets 2.9.5
|
|
@style{wxSTAY_ON_TOP}
|
|
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.

The arguments of this function can be either strings or one of the
|
|
standard identifiers, such as @c wxID_APPLY or @c wxID_OPEN. Notice
|
|
that even if the label is specified as an identifier, the return value
|
|
of the dialog ShowModal() method still remains one of @c wxID_OK, @c
|
|
wxID_CANCEL, @c wxID_YES or @c wxID_NO values, i.e. this identifier
|
|
changes only the label appearance but not the return code generated by
|
|
the button. It is possible to mix stock identifiers and string labels
|
|
in the same function call, for example:
|
|
@code
|
|
wxMessageDialog dlg(...);
|
|
dlg.SetYesNoLabels(wxID_SAVE, _("&Don't save"));
|
|
@endcode
|
|
|
|
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, the labels were set
|
|
successfully.
|
|
|
|
Typically, if the function was used successfully, the main dialog
|
|
message may need to be changed, e.g.:
|
|
@code
|
|
wxMessageDialog dlg(...);
|
|
if ( dlg.SetYesNoLabels(_("&Quit"), _("&Don't quit")) )
|
|
dlg.SetMessage(_("What do you want to do?"));
|
|
else // buttons have standard "Yes"/"No" values, so rephrase the question
|
|
dlg.SetMessage(_("Do you really want to quit?"));
|
|
@endcode

Show a general purpose message dialog.
|
|
|
|
This is a convenient function which is usually used instead of using
|
|
wxMessageDialog directly. Notice however that some of the features, such as
|
|
extended text and custom labels for the message box buttons, are not
|
|
provided by this function but only by wxMessageDialog.
|
|
|
|
The return value is one of: @c wxYES, @c wxNO, @c wxCANCEL, @c wxOK or @c
|
|
wxHELP (notice that this return value is @b different from the return value
|
|
of wxMessageDialog::ShowModal()).
|
|
|
|
For example:
|
|
@code
|
|
int answer = wxMessageBox("Quit program?", "Confirm",
|
|
wxYES_NO | wxCANCEL, main_frame);
|
|
if (answer == wxYES)
|
|
main_frame->Close();
|
|
@endcode
|
|
|
|
@a message may contain newline characters, in which case the message will
|
|
be split into separate lines, to cater for large messages.
|
|
|
|
@param message
|
|
Message to show in the dialog.
|
|
@param caption
|
|
The dialog title.
|
|
@param parent
|
|
Parent window.
|
|
@param style
|
|
Combination of style flags described in wxMessageDialog documentation.
|
|
@param x
|
|
Horizontal dialog position (ignored under MSW). Use ::wxDefaultCoord
|
|
for @a x and @a y to let the system position the window.
|
|
@param y
|
|
Vertical dialog position (ignored under MSW).
