Setting transitions between Page and Page Host nodes

Kanzi by default uses the Push transition for transitions between Page and Page Host nodes. You can create your own transitions using:

• Transition Presets to set to and from transitions between Page and Page Host nodes.
• Animations to set or customize transitions between Page and Page Host nodes.

In Kanzi transitions are resources you can reuse. You can see transitions in a Kanzi Studio project in the Library > Page Transitions.

Setting transitions between Page and Page Host nodes

To set the transitions between Page and Page Host nodes:

1. Create a user interface structure using Page and Page Host nodes. See Using the Page and Page Host nodes.
2. In the Pages click Transitions to show the Transitions editor in the Pages.
   
3. In the Pages click any Page or Page Host node to select it and in the Transitions editor click to create a transition.
   The Transitions editor shows the transitions used by the Page or Page Host node you select either in the Pages or the Project. When you create a transition, Kanzi Studio by default uses the Push transition.
   
4. In the Transitions editor drag from the Transition Presets a transition and drop it below the Default transition.
   That way you add a transition to the Default transition between this and any other Page or Page Host node.
   For example, drag the Flip transition from the Transition Presets and drop it below the Default transition in the Transitions editor.
   In the Preview when you start a transition either from or to the Page node for which you set the transition type, Kanzi uses the transition you set.

   Swivel
5. To configure the transition, in the Transitions editor click and in the popup window set:
   • Duration to the length of the transition in milliseconds.
   • From to the Page or Page Host node to which you want to apply this transition when you navigate from that node.
   • To to the Page or Page Host node to which you want to apply this transition when you navigate to that node.
   • Direction to whether the transition applies to the transition from the node you set in the From property to the node you set in the To property, or to the transitions from both nodes:
     • Bidirectional applies the transition to the transition from the node in the From property to the node in the To property, and from the node in the To property to the node in the From property.
     • Unidirectional applies the transition only to the node in the From property to the node in the To property.
   

Creating transition animations

Use transition animations to set transitions between Page and Page Host nodes, or to customize transitions.

To create a transition animation:

1. In the Library > Page Transitions press Alt and right-click the transition to which you want to add a transition animation and select Page Transition Animation.
   
2. In the Library select the transition animation you created in the previous step and in the Properties set:
   • Animation Target to:
     • Page In to use the animation when navigating to the set Page or Page Host node
     • Page Out to use the animation when navigating from the set Page or Page Host node
   • Transition Property to the property you want to animate.
   • Start Value to the value of the Transition Property when the transition animation starts.
   • End Value to the value of the Transition Property when the transition animation ends.
   
3. To set a Page or Page Host to use the transition animation you created, in the Project select that Page or Page Host node, and in the Properties set the Transitions property to the transition which uses the animation.
   

Adding transition animations to transitions

To customize a transition you can add a transition animation to an existing transition.

To add a transition animation to a transition:

1. In the Pages click Transitions to show the Transitions editor in the Pages.
   
2. In the Pages select the Page or Page Host node to which you want to add a transition animation and in the Transitions editor from the Animations drag an animation to the transition you want to customize.
   For example, drag the Scale animation to the Default transition to add scale animation to the Default transition.
   
3. (Optional) To customize a transition animation, in the Library > Page Transitions expand the transition which uses that animation, select the transition animation, and in the Properties set:
   • Start Value to the value of the Transition Property when the animation starts.
     
   • End Value to the value of the Transition Property when the animation ends.
   

Starting transitions between Page nodes in your application

When you click a Page or a Page Host node in the Pages, in the Preview you can see the transition. However, to transition between the nodes in your application you need to use a trigger with one of the Navigate to actions.

To start a transition between Page nodes in your application:

1. Create a user interface structure using Page and Page Host nodes. See Using the Page and Page Host nodes.
2. In the Project add a control you want to use to navigate between Page and Page Host nodes.
   For example, select the RootPage Page Host node and create a Button 2D. See Using the Button nodes.
   
3. In the Project select the control you created in the previous step, in the Node Components > Triggers section in the trigger type you want to use for the navigation click the Add dropdown menu, and select an action:
   • Navigate to Page goes to the node you set in this action.
   • Navigate to Next goes to the sibling node which is on the right side of the current node as shown in the Pages.
   • Navigate to Previous goes to the sibling node which is on the left side of the current node as shown in the Pages.
   • Navigate to Parent goes to the node that is the parent node of the node you select in this action.
   For example, select the Navigate to Next action and set the action to the RootPage node.
   
   In the Preview click the button. Every time you click the button you advance one page to the right: Home to Music, Music to Car, Car to Home, and so on.
