Struct gtk4::MessageDialog [−][src]
pub struct MessageDialog(_);Expand description
MessageDialog presents a dialog with some message text.
It’s simply a convenience widget; you could construct the equivalent of
MessageDialog from Dialog without too much effort, but
MessageDialog saves typing.
The easiest way to do a modal message dialog is to use the DialogFlags::MODAL
flag, which will call GtkWindowExt::set_modal() internally. The dialog will
prevent interaction with the parent window until it’s hidden or destroyed.
You can use the signal::Dialog::response signal to know when the user
dismissed the dialog.
An example for using a modal dialog: ⚠️ The following code is in c ⚠️
GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT | GTK_DIALOG_MODAL;
dialog = gtk_message_dialog_new (parent_window,
flags,
GTK_MESSAGE_ERROR,
GTK_BUTTONS_CLOSE,
"Error reading “%s”: %s",
filename,
g_strerror (errno));
// Destroy the dialog when the user responds to it
// (e.g. clicks a button)
g_signal_connect (dialog, "response",
G_CALLBACK (gtk_window_destroy),
NULL);You might do a non-modal MessageDialog simply by omitting the
DialogFlags::MODAL flag:
⚠️ The following code is in c ⚠️
GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
dialog = gtk_message_dialog_new (parent_window,
flags,
GTK_MESSAGE_ERROR,
GTK_BUTTONS_CLOSE,
"Error reading “%s”: %s",
filename,
g_strerror (errno));
// Destroy the dialog when the user responds to it
// (e.g. clicks a button)
g_signal_connect (dialog, "response",
G_CALLBACK (gtk_window_destroy),
NULL);GtkMessageDialog as GtkBuildable
The MessageDialog implementation of the Buildable interface exposes
the message area as an internal child with the name “message_area”.

Implementations
Creates a new builder-pattern struct instance to construct MessageDialog objects.
This method returns an instance of MessageDialogBuilder which can be used to create MessageDialog objects.
Returns the message area of the dialog.
This is the box where the dialog’s primary and secondary labels
are packed. You can add your own extra content to that box and it
will appear below those labels. See DialogExt::content_area()
for the corresponding function in the parent Dialog.
Returns
A Box corresponding to the
“message area” in the self
The type of the message.
The type of the message.
The secondary text of the message dialog.
The secondary text of the message dialog.
true if the secondary text of the dialog includes Pango markup.
See parse_markup().
true if the secondary text of the dialog includes Pango markup.
See parse_markup().
The primary text of the message dialog.
If the dialog has a secondary text, this will appear as the title.
The primary text of the message dialog.
If the dialog has a secondary text, this will appear as the title.
true if the primary text of the dialog includes Pango markup.

pub fn new<T: IsA<Window>>(

) -> Self
Creates a new message dialog.
This is a simple dialog with some text the user may want to see.
When the user clicks a button a “response” signal is emitted with
response IDs from ResponseType. See Dialog
for more details.

) -> Self
pub fn with_markup<P: IsA<Window>>(
parent: Option<&P>,
flags: DialogFlags,
type_: MessageType,
buttons: ButtonsType,
message: Option<&str>
) -> Self
Creates a new message dialog.
This is a simple dialog with some text that is marked up with
Pango markup. When the user clicks a button a “response” signal
is emitted with response IDs from ResponseType. See
Dialog for more details.
Special XML characters in the printf() arguments passed to this
function will automatically be escaped as necessary.
(See g_markup_printf_escaped() for how this is implemented.)
Usually this is what you want, but if you have an existing
Pango markup string that you want to use literally as the
label, then you need to use set_markup()
instead, since you can’t pass the markup string either
as the format (it might contain “%” characters) or as a string
argument.
⚠️ The following code is in c ⚠️
GtkWidget *dialog;
GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
dialog = gtk_message_dialog_new (parent_window,
flags,
GTK_MESSAGE_ERROR,
GTK_BUTTONS_CLOSE,
NULL);

buttons

message_format
printf()-style format string
Returns
a new MessageDialog
Sets the secondary text of the message dialog.
The message_format is assumed to contain Pango markup.
Due to an oversight, this function does not escape special
XML characters like with_markup()
does. Thus, if the arguments may contain special XML characters,
you should use g_markup_printf_escaped() to escape it.
⚠️ The following code is in c ⚠️
char *msg;
msg = g_markup_printf_escaped (message_format, ...);
gtk_message_dialog_format_secondary_markup (message_dialog,
"%s", msg);
g_free (msg);message_format
printf()-style string with Pango markup
