A Fuse App contains an implicit GraphicsView at the root level, which ensures that UI components are renderered using high performance OpenGL graphics by default.
To display native stock controls that are bundled with the platform's OS, you can use a NativeViewHost. Some Controls are only available as native Controls (e.g. WebView or MapView), while others are available as both native and graphics Controls (e.g. ScrollView or Rectangle).
Note: Native Controls are always rendered in front of graphics controls.
The only exception is when Fuse.Controls.NativeViewHost.RenderToTexture is enabled, which comes with its own set of limitations.
WebView is only available as a native view. Here's how to display one:
<Panel> <NativeViewHost> <WebView Url="http://example.com" /> </NativeViewHost> </Panel>
We can also layer native Controls over each other and form heirarchies within the
NativeViewHost, just like with regular UX markup:
<Panel> <NativeViewHost> <Panel Alignment="Top" Padding="15" Color="#0006"> <Text>This text is layered on top of the WebView</Text> </Panel> <WebView Url="http://example.com" /> </NativeViewHost> </Panel>
You can use the
RenderToTexture property to render the native view to a texture to enable correct layer-compositing with
other graphics-based Visuals. Note that this comes at a performance cost, and native views are not interactive while being
rendered to texture.
<Text Alignment="Center">This text is layered on top of the NativeViewHost</Text> <NativeViewHost RenderToTexture="true"> <Rectangle Color="#324" /> </NativeViewHost>
To make an app consisting solely of native components, place a
<NativeViewHost> at the root level of your app:
<App> <NativeViewHost> <!-- entire app goes here --> </NativeViewHost> </App>

Begins removing a given visual, playing all RemovedAnimations before actual removal.
Requests that this visual be brought into the visible are of the screen. Typically a containing
ScrollView will scroll to ensure it is visible.
Brings the given child to the front of the Z-order. In UX markup, use the BringToFront trigger action instead.
ChildCount : int uno
The number of child nodes of this visual.
Children : IList of Node ux
The children of the visual. All nodes placed inside the visual in UX markup are assigned to this list. The order of Visuals this list determines the order of layout. The Z-order of the children is by default equal to this order, but can be manipulated separately using methods like BringToFront and SendToBack.

FirstChild<T> : T uno
FirstVisualChild : Visual uno
GetVisualChild(int) : Visual uno
GetZOrderChild(int) : Visual uno

Whether this visual has any visual child nodes.
HitTestBounds : VisualBounds uno
IfSnap(float2) : float2 uno
IfSnapDown(float2) : float2 uno
IfSnapUp(float2) : float2 uno
Indicates the visual for this node has changed. This allows the root-level node to know that it must draw, and any caching that it must invalidate the cache for this node.
Indicates the composition of the visual has changed, but that the visual drawing itself is still valid (for example a position change).
IsContextEnabled : bool uno
Whether this node is in an enabled context.
The context is disabled if one of the ancestor nodes have IsEnabled set to
IsInteracting : bool uno
IsLocalVisible : bool uno
Returns whether this visual is visible without concern for whether an ancestor visual is hidden or collapsed.
Returns whether this visual is currently visible. Will return false if any of the ancestor visuals are hidden or collapsed. This property can not be used to check whether a visual is hidden because it is occluded by another visual, or is outside the view but otherwise visible.
LastChild<T> : T uno
LastVisualChild : Visual uno
The layer this visual belongs to in the Parent container.
LayoutRole : LayoutRole ux
Describes how this visual participates in layout.

Converts a coordinate from the local space into the parent space.
LocalTransform : float4x4 uno
OnInvalidateRenderBounds : bool uno
Remove(Node) : bool uno

Sends the given child to the back of the Z-order. In UX markup, use the SendToBack trigger action instead.

ContextParent : Node uno
The context parent is the semantic parent of this node. It is where non-UI structure should be resolved, like looking for the DataContext, a Navigation, or other semantic item.
FindByType<T> : T uno
Finds the first node with a given name that satisfies the given acceptor. The serach algorithm works as follows: Nodes in the subtree are matched first, then it matches the nodes in the subtrees ofthe ancestor nodes by turn all the way to the root. If no matching node is found, the function returns null.
GetFirstData : object uno
GetNearestAncestorOfType<T> : T uno
IsRootingCompleted : bool uno
Whether rooting for this node is completed. Returns false if unrooting has started.
IsRootingStarted : bool uno
Whether rooting of this node has started. Note that even if this property returns true, rooting may not yet be completed for the node. See also IsRootingCompleted.
Run-time name of the node. This property is automatically set using the ux:Name attribute.
NextSibling<T> : T uno
Returns the next sibling node of the given type.
If you override
OnRooted you must call
base.OnRooted() first in your derived class. No other processing should happen first, otherwise you might end up in an undefined state.
