DialogGidBuilderImpl.useHeaderBar

T useHeaderBar(int propval)

Set useHeaderBar property.

Parameters

propvaltrue 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 [gtk.dialog.Dialog] subclasses such as [gtk.color_chooser_dialog.ColorChooserDialog] set this property according to platform conventions (using the property@Gtk.Settings:gtk-dialogs-use-header setting). Here is how you can achieve the same: 
g_object_get (settings, "gtk-dialogs-use-header", &header, NULL);
   dialog = g_object_new (GTK_TYPE_DIALOG, header, TRUE, NULL);

Returns

Builder instance for fluent chaining

Deprecated

Use [gtk.window.Window] instead
