Required Methods§
sourcefn add_action_widget(&self, child: &impl IsA<Widget>, response_id: ResponseType)
fn add_action_widget(&self, child: &impl IsA<Widget>, response_id: ResponseType)
Adds an activatable widget to the action area of a Dialog.
GTK connects a signal handler that will emit the
response signal on the dialog when the widget
is activated. The widget is appended to the end of the dialog’s action
area.
If you want to add a non-activatable widget, simply pack it into
the @action_area field of the Dialog struct.
Deprecated since 4.10
Use Window instead
child
an activatable widget
response_id
response ID for @child
Adds a button with the given text.
GTK arranges things so that clicking the button will emit the
response signal with the given @response_id.
The button is appended to the end of the dialog’s action area.
The button widget is returned, but usually you don’t need it.
Deprecated since 4.10
Use Window instead
button_text
text of button
response_id
response ID for the button
Returns
the Button widget that was added
sourcefn content_area(&self) -> Box
fn content_area(&self) -> Box
Returns the content area of @self.
Deprecated since 4.10
Use Window instead
Returns
the content area Box.
sourcefn header_bar(&self) -> HeaderBar
fn header_bar(&self) -> HeaderBar
Returns the header bar of @self.
Note that the headerbar is only used by the dialog if the
use-header-bar property is true.
Deprecated since 4.10
Use Window instead
Returns
the header bar
sourcefn widget_for_response(&self, response_id: ResponseType) -> Option<Widget>
fn widget_for_response(&self, response_id: ResponseType) -> Option<Widget>
Gets the widget button that uses the given response ID in the action area of a dialog.
Deprecated since 4.10
Use Window instead
response_id
the response ID used by the @self widget
Returns
the @widget button that uses the given @response_id
sourcefn response(&self, response_id: ResponseType)
fn response(&self, response_id: ResponseType)
Emits the ::response signal with the given response ID.
Used to indicate that the user has responded to the dialog in some way.
Deprecated since 4.10
Use Window instead
response_id
response ID
sourcefn set_default_response(&self, response_id: ResponseType)
fn set_default_response(&self, response_id: ResponseType)
Sets the default widget for the dialog based on the response ID.
Pressing “Enter” normally activates the default widget.
Deprecated since 4.10
Use Window instead
response_id
a response ID
sourcefn set_response_sensitive(&self, response_id: ResponseType, setting: bool)
fn set_response_sensitive(&self, response_id: ResponseType, setting: bool)
A convenient way to sensitize/desensitize dialog buttons.
Calls gtk_widget_set_sensitive (widget, @setting)
for each widget in the dialog’s action area with the given @response_id.
Deprecated since 4.10
Use Window instead
response_id
a response ID
setting
true for sensitive
sourcefn use_header_bar(&self) -> i32
fn use_header_bar(&self) -> i32
true if the dialog uses a headerbar for action buttons
instead of the action-area.
For technical reasons, this property is declared as an integer
property, but you should only set it to true or false.
Creating a dialog with headerbar
Builtin Dialog subclasses such as ColorChooserDialog
set this property according to platform conventions (using the
gtk-dialogs-use-header setting).
Here is how you can achieve the same:
⚠️ The following code is in c ⚠️
g_object_get (settings, "gtk-dialogs-use-header", &header, NULL);
dialog = g_object_new (GTK_TYPE_DIALOG, header, TRUE, NULL);
Deprecated since 4.10
Use Window instead
sourcefn connect_close<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_close<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
Emitted when the user uses a keybinding to close the dialog.
This is a keybinding signal.
The default binding for this signal is the Escape key.
Deprecated since 4.10
Use Window instead
fn emit_close(&self)
sourcefn connect_response<F: Fn(&Self, ResponseType) + 'static>(
&self,
f: F
) -> SignalHandlerId
fn connect_response<F: Fn(&Self, ResponseType) + 'static>( &self, f: F ) -> SignalHandlerId
Emitted when an action widget is clicked.
The signal is also emitted when the dialog receives a
delete event, and when response() is called.
On a delete event, the response ID is ResponseType::DeleteEvent.
Otherwise, it depends on which action widget was clicked.
Deprecated since 4.10
Use Window instead
response_id
the response ID
