@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. May be combined with
|
|
@c wxCANCEL.
|
|
@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
|
|
@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_EXCLAMATION}
|
|
Displays an exclamation, or warning, icon in the dialog.
|
|
@style{wxICON_ERROR}
|
|
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.
|
|
@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 and not only
|
|
just its parent (currently implemented only under MSW and GTK).

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
|
|
|
|
@since 2.9.0

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 or @c wxOK
|
|
(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).
