GettingStartedControls Part 3

In Part 3 of the GettingStartedControls Sample we will create a (Phone Connection) Options scene. This scene offers the possibility to choose the connection type (Cable, Bluetooth and other) from a Dial Control on the left side. On theThe right side isdisplays a List withof devices. When a device gets selected, an associated Sub-List Controls.Control Thewith Sub-Listtwo ControlTextButtons will appearbe dependingshown. on the item selected in the List.

As basis for step 3 of our GettingStartedControls tutorial, please use your own created solution from the previous "GettingStartedControls" tutorial.

And this is what the final scene will look like:

Configure Behaviors for MyList's Sub-List

The visibility of the Sub-List shall be toggled by clicking the MainItem. Let's configure the necessary behaviors to the Sub-List.

1. From the Toolbox panel's [ Behaviors ] section under "Value Processing" drag a Value behavior into the Scene Tree panel directly onto MyList's Sub-List node.
   • In the Scene Tree panel the Sub-List node got marked a yellow square, indicating that a behavior is attached to it.
   • In the Scene Tree panel's right side you can see the Value behavior.
2. In the Scene Tree panel's right side select the Sub-List node's Value behavior. In the Properties panel change the Variant to "Bool". Don't check the nearby checkbox.
   • The Value behavior's type has been changed to Bool.
3. From the Toolbox panel's [ Behaviors ] section  under "Value Processing" drag an Action On Value behavior into the Scene Tree's right side directly onto the Value behavior's Receivers slot.
   • In the Scene Tree panel you can see that an Action On Value behavior is configured as Receiver of the Value Processing behavior.
   • Action On Value can now be used to configure an action that will be executed when a new value has been received and the visibility of the Sub-List is toggled.
4. From the Toolbox panel's [ Behaviors ] section under "Condition - Control" drag a Check Processed Value behavior into the Scene Tree panel's right side directly onto the Action On Value behavior's Condition.
   • In the Scene Tree panel's right side you can see that the Check Processed Value behavior is configured as condition for the Action On Value behavior.
5. In the Scene Tree panel's right side select the Check Processed Value behavior. In the Properties panel configure the properties ConditionOperator and ConditionValue as in the table below.
   • The Check Processed Value behavior's properties have been configured.
   • Only if the the value received from "MainItem/SendValue as Event" is TRUE, an action (which will be defined in later steps) shall be performed.

     Behavior	Property	Value
     Check Processed Value	ConditionOperator	Equal
     	ConditionValue	Bool, TRUE

6. From the Toolbox panel's [ Behaviors ] section under "Action - Control" drag a "Set Control State" behavior into the Scene Tree panel's right side directly onto the Action On Value behavior's Action slot.
   
   • In the Scene Tree panel's right side you can see that the Set Control State behavior is configured as the Action On Value behavior's action.
7. In the Scene Tree panel's right side select the Set Control State behavior. In the Properties panel configure the properties State and Change To according to the table below.
   • The Set Control State behavior is configured as in the table below.
   • The Sub-List will be enabled whenever the condition Check Processed Value evaluates to TRUE.

     Behavior	Property	Value
     Set Control State	State	Enabled
     	ChangeTo	TRUE

8. Repeat steps 3 to 7: Add a new Action On Value behavior as Value behavior's Receiver, configure another Check Processed Value condition and another Set Control State according to the table and image below.
   
   • In the Scene Tree panel's right side you can see the behaviors are configured as in the table and image below.
   • All behaviors for MyList's Sub-List have been configured.
     

     Behavior	Property	Value
     Action On Value_1	-	-
     Check Processed Value_1	ConditionOperator	Equal
     	ConditionValue	Bool, FALSE
     Set Control State_1	State	Enabled
     	ChangeTo	FALSE

     

Test MyList in the Player

Let's test if the configured behaviors of MyList control are functional.

1. Save your solution either via the menu "File - Save Solution" or via the keyboard <Ctrl + S>.
   
   • The solution has been saved.
2. In the Scene Composer's Toolbar click on "Play selected scenario...".
   • The resources will be generated and the Player will be started.
     
3. In the CGI Panel check Scenes#SceneOptions and uncheck SceneHome and SceneClimate
   • In the Player window SceneOptions will be displayed with the Connection Dial on the left side and the empty Devices List on the right side, displaying the scrollbar.
     
4. In the Player window click intothe first item of the empty Devices List, where you would expect the firsttext listof element.which is "Text".
   • In the Player window's empty Devices List an orange border will be displayed indicating the selected MainItem.
   • Additionally, the Sub-List with the TextButtons "Connect" and "Unpair" will be displayed below the selected MainItem.
     
5. In the Player window click the selected MainItem again.
   • The TextButtons of the Sub-List will disappear.
6. In the Scene Composer's Toolbar click the "Close the Player" button.
   • The Player and CGI Panel window will be closed.
     

Configure a Devices List using MyList

So far we have been working on our MyList control with only one single list entry. Now that this first list entry is fully configured, we can create more of them.

1. In the Scene Tree panel select the Main Item and the Sub-List. Copy and paste them to create 4 more instances. This can be done either via the context menu [ Copy ] and [ Paste ] or via the keyboard shortcuts <Ctrl + c> and <Ctrl + v>.
   • In the Scene Tree panel you can see that MyList's ListContentGroup now contains 5 MainItems and 5 Sub-Lists.
     
2. In the Scene Tree panel select the MainItems individually. ThenThen, in the Scene Tree panel's right side, select their configured "Send Value As Event" behaviors. In the Properties panel adapt the TargetNodes to their respective MainItems. I.e. MainItem_4 will be configured as the TargetNode of MainItem_4's "Send Value As Event" behavior.
   • The "Send Value As Event" behaviors' TargetNodes are configured with the respective MainItems.

3. To easily set the Target Node lock the Properties panel using the pad lock icon in the top right corner. From the Scene Tree panel drag the Sub-List node into the Properties panel directly onto the input field next to "TargetNode". Finally, don't forget to unlock the Properties panel clicking the pad lock icon once again.
