All Implemented Interfaces:

Accessible, Buildable, ConstraintTarget, Proxy

@Generated("io.github.jwharm.JavaGI")
public class NavigationPage
extends Widget
implements Accessible, Buildable, ConstraintTarget

A page within NavigationView or NavigationSplitView.

Each page has a child widget, a title and optionally a tag.

The NavigationPage::showing, NavigationPage::shown, NavigationPage::hiding and NavigationPage::hidden signals can be used to track the page's visibility within its AdwNavigationView.

Header Bar Integration
When placed inside AdwNavigationPage, HeaderBar will display the page title instead of window title.

When used together with NavigationView, it will also display a back button that can be used to go back to the previous page. Set HeaderBar:show-back-button to FALSE to disable that behavior if it's unwanted.

CSS Nodes
AdwNavigationPage has a single CSS node with name navigation-view-page.

Accessibility
AdwNavigationPage uses the GTK_ACCESSIBLE_ROLE_GROUP role.

Since:

1.4

Constructor Details

NavigationPage

public NavigationPage(MemorySegment address)

Create a NavigationPage proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

NavigationPage

public NavigationPage(Widget child,
 String title)

Creates a new AdwNavigationPage.

Parameters:

child - the child widget

title - the page title

Since:

1.4

NavigationPage

public NavigationPage()

Creates a new NavigationPage.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the NavigationPage class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected NavigationPage asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Widget

withTag

public static NavigationPage withTag(Widget child,
 String title,
 String tag)

Creates a new AdwNavigationPage with provided tag.

Parameters:

child - the child widget

title - the page title

tag - the page tag

Returns:

the new created AdwNavigationPage

Since:

1.4

getCanPop

setCanPop

public void setCanPop(boolean canPop)

Sets whether this NavigationPage can be popped from navigation stack.

Set it to FALSE to disable shortcuts and gestures, as well as remove the back button from HeaderBar.

Manually calling NavigationView.pop() or using the navigation.pop action will still work.

The tag can be used to retrieve the page with NavigationView.findPage(java.lang.String), as well as with NavigationView.pushByTag(java.lang.String), NavigationView.popToTag(java.lang.String) or NavigationView.replaceWithTags(java.lang.String[]).

Tags must be unique within each NavigationView.

The tag also must be set to use the navigation.push action.

Parameters:

tag - the page tag

Since:
