GtkNativeDialog

GtkNativeDialog — Integrate with native dialogs

Types and Values

Includes

#include <gtk/gtk.h>

Description

Native dialogs are platform dialogs that don't use GtkDialog or GtkWindow. They are used in order to integrate better with a platform, by looking the same as other native applications and supporting platform specific features.

The GtkDialog functions cannot be used on such objects, but we need a similar API in order to drive them. The GtkNativeDialog object is an API that allows you to do this. It allows you to set various common properties on the dialog, as well as show and hide it and get a “response” signal when the user finished with the dialog.

There is also a gtk_native_dialog_run() helper that makes it easy to run any native dialog in a modal way with a recursive mainloop, similar to gtk_dialog_run().

Functions

gtk_native_dialog_show ()

void
gtk_native_dialog_show (GtkNativeDialog *self);

Shows the dialog on the display, allowing the user to interact with it. When the user accepts the state of the dialog the dialog will be automatically hidden and the “response” signal will be emitted.

Multiple calls while the dialog is visible will be ignored.

Parameters

self

a GtkNativeDialog

 

Since: 3.20


gtk_native_dialog_hide ()

void
gtk_native_dialog_hide (GtkNativeDialog *self);

Hides the dialog if it is visilbe, aborting any interaction. Once this is called the “response” signal will not be emitted until after the next call to gtk_native_dialog_show().

If the dialog is not visible this does nothing.

Parameters

self

a GtkNativeDialog

 

Since: 3.20


gtk_native_dialog_destroy ()

void
gtk_native_dialog_destroy (GtkNativeDialog *self);

Destroys a dialog.

When a dialog is destroyed, it will break any references it holds to other objects. If it is visible it will be hidden and any underlying window system resources will be destroyed.

Note that this does not release any reference to the object (as opposed to destroying a GtkWindow) because there is no reference from the windowing system to the GtkNativeDialog.

Parameters

self

a GtkNativeDialog

 

Since: 3.20


gtk_native_dialog_get_visible ()

gboolean
gtk_native_dialog_get_visible (GtkNativeDialog *self);

Determines whether the dialog is visible.

Parameters

self

a GtkNativeDialog

 

Returns

TRUE if the dialog is visible

Since: 3.20


gtk_native_dialog_set_modal ()

void
gtk_native_dialog_set_modal (GtkNativeDialog *self,
                             gboolean modal);

Sets a dialog modal or non-modal. Modal dialogs prevent interaction with other windows in the same application. To keep modal dialogs on top of main application windows, use gtk_native_dialog_set_transient_for() to make the dialog transient for the parent; most window managers will then disallow lowering the dialog below the parent.

Parameters

self

a GtkNativeDialog

 

modal

whether the window is modal

 

Since: 3.20


gtk_native_dialog_get_modal ()

gboolean
gtk_native_dialog_get_modal (GtkNativeDialog *self);

Returns whether the dialog is modal. See gtk_native_dialog_set_modal().

Parameters

self

a GtkNativeDialog

 

Returns

TRUE if the dialog is set to be modal

Since: 3.20


gtk_native_dialog_set_title ()

void
gtk_native_dialog_set_title (GtkNativeDialog *self,
                             const char *title);

Sets the title of the GtkNativeDialog.

Parameters

self

a GtkNativeDialog

 

title

title of the dialog

 

Since: 3.20


gtk_native_dialog_get_title ()

const char *
gtk_native_dialog_get_title (GtkNativeDialog *self);

Gets the title of the GtkNativeDialog.

Parameters

self

a GtkNativeDialog

 

Returns

the title of the dialog, or NULL if none has been set explicitly. The returned string is owned by the widget and must not be modified or freed.

[nullable]

Since: 3.20


gtk_native_dialog_set_transient_for ()

void
gtk_native_dialog_set_transient_for (GtkNativeDialog *self,
                                     GtkWindow *parent);

Dialog windows should be set transient for the main application window they were spawned from. This allows window managers to e.g. keep the dialog on top of the main window, or center the dialog over the main window.

Passing NULL for parent unsets the current transient window.

Parameters

self

a GtkNativeDialog

 

parent

parent window, or NULL.

[allow-none]

Since: 3.20


gtk_native_dialog_get_transient_for ()

GtkWindow *
gtk_native_dialog_get_transient_for (GtkNativeDialog *self);

Fetches the transient parent for this window. See gtk_native_dialog_set_transient_for().

Parameters

self

a GtkNativeDialog

 

Returns

the transient parent for this window, or NULL if no transient parent has been set.

[nullable][transfer none]

Since: 3.20


gtk_native_dialog_run ()

gint
gtk_native_dialog_run (GtkNativeDialog *self);

Blocks in a recursive main loop until self emits the “response” signal. It then returns the response ID from the ::response signal emission.

Before entering the recursive main loop, gtk_native_dialog_run() calls gtk_native_dialog_show() on the dialog for you.

After gtk_native_dialog_run() returns, then dialog will be hidden.

Typical usage of this function might be:

1
2
3
4
5
6
7
8
9
10
11
gint result = gtk_native_dialog_run (GTK_NATIVE_DIALOG (dialog));
switch (result)
  {
    case GTK_RESPONSE_ACCEPT:
       do_application_specific_something ();
       break;
    default:
       do_nothing_since_dialog_was_cancelled ();
       break;
  }
g_object_unref (dialog);

Note that even though the recursive main loop gives the effect of a modal dialog (it prevents the user from interacting with other windows in the same window group while the dialog is run), callbacks such as timeouts, IO channel watches, DND drops, etc, will be triggered during a gtk_native_dialog_run() call.

Parameters

self

a GtkNativeDialog

 

Returns

response ID

Since: 3.20

struct GtkNativeDialogClass {
  GObjectClass parent_class;
