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 the right side is a List with Sub-List Controls. The Sub-List Control will appear depending 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:

Preparing the Options scene

1. Create a new scene via the menu "Scene" - "New 2D Scene" or press < Ctrl+2 > on your keyboard
   
   • The "Add New Scene 2D" dialog will be opened.
     
2. In the first row select "/Scenes" from the drop-down menu. Enter "SceneOptions" as name and press [ OK ]. We use the prefix "Scene" to have all scenes listed next to each other in the Solution Explorer panel.
   • A new scene "SceneOptions" is created and visible in the Solution Explorer panel in folder "Scenes".
   • The new scene is opened in the Scene Editor and in the Scene Tree panel.
   • In the Scene Tree panel you can see that the scene already has a camera.
   • In the Render Targets panel you can see that the camera is already added to the RenderTarget.
     
3. In the Render Targets panel check the checkbox of "SceneOptions\Camera" in order to enable rendering.
4. In the Render Targets panel select the SceneOptions\Camera. In the Properties panel's [ Camera ] section change the sequence number to 2.
   • The camera's sequence number is set to 2.
   • In the Scene Tree panel the red Information/Warning/Error square disappears.
     

Importing Images

This scene uses the built-in Scene Composer controls but they will be customized with new images. Therefore these images have to be imported into the Scene Composer solution.

Create Sub-List

1. In the Scene Tree panel double-click on the MyList node.
   • Scene Tree panel switches from SceneOptions to MyList.
   • You are now able to edit the MyList template.
2. From the Toolbar's [ 2D Nodes ] section drag a OverlayLayout into the Scene Tree panel directly onto the List's "ListContentGroup" (MyList > List > ListContentGroup).

   • In the Scene Tree panel there are a RenderNode and a TextNode inside the OverlayLayout that was created in the previous step.
   • In the Scene Editor the TextNode is visible displaying the TextNode's default text "Text".
     
4. In the Scene Tree panel rename the nodes created in the previous steps rename them either via the context menu entry "Rename" or by pressing <F2> on your keyboard according to the table below.
   • In the Scene Tree panel the nodes are renamed according to the following table.

     Initial Name	New Name
     OverlayLayout	MainItem
     TextNode	FocusImage
     RenderNode	EntryName

5. In the Scene Tree panel select the List (Group2D). In the Properties panel  [ Transformation ] section configure the position and size according to the following table.
   
   • In Scene Editor the Position and size of the selected rectangle is adjusted according to the new settings.

   • Size X and Size Y properties are initially set to "Automatic" and greyed out. Clicking onto the "A" next to the greyed-out input field allows you to edit these properties.

     Target Item	Transformation		Layout
     	Position X	Position Y	Size X	Size Y
     List (Group2D)	58	134	300	300

First, add a TextNode to the GroupNode "Devices" for the "Devices" label.

Rename it to TextNode_Devices and set its text to "Devices" and set its position to X:145 Y: 61.

Next step is to customize an existing List control and set its color of the Scrollbar to orange (original color is blue). At first, drag and drop List Control from ConstructionKit > Controls in Solution Explorer onto SceneOptions in Scene Tree panel.

In our list the currently selected main list item shall be highlighted with an orange outline.
Therefore drag a BitmapBrushColorBlend effect from the ToolBox onto the FocusImage node. Now select the BitmapBrushColorBlend Effect on the right side of the Scene Tree Panel and set its Image to the BorderFocusedBmp image (which is part of the ConstructionKit) and its Color properties as follows:

Now, select the FocusImage node and change its layout properties: Set the StretchBehavior to "Fill".

In the following steps we will create a sub-list. Drag a Sub-List control from the Toolbox to the List's ListContentGroup.

The Sub-List control has a SublistAnchor. Drag a StackLayout onto this SubListAnchor. Now, drag a TextButton into the StackLayout and change its name to "TextButton_Connect".
The resulting structure should look like this:

The next step is to configure the TextButton:

The TextButton's images (Normal Image, Pressed Image and Focused Image) need to be adjusted:

Copy and paste the TextButton to make another copy. Rename the other as "TextButton_Unpair", and set its Text property to "Unpair". Resulting structure should look like this:

Setting up the "Devices" List behaviors

Focus Handling behaviors

For the Devices entry items, we need to set the behaviors for focus handling. We want the item to be highlighted only when it is focused. So first, we need to disable Rendering of the FocusImage by default. In the FocusImage properties, uncheck "Enable Rendering":

Next, in order for the "MainItem" Group Node to send events such as Focus Event when clicked, we have to add a "Handle Control State" behavior (Behaviors > Control > Internal) to MainItem Group Node.

Then, to handle these events received, add a "Focus" and "FocusLeave" Event Handler from the Toolbox under Behaviors > Control onto the MainItem Group Node.

Under each "Actions" of each Focus Event Handler, add an "Enable Rendering" behavior from the Toolbox under Behaviors > Action > Property.

This is what the configured Behaviors look like now:

As soon as the MainItem gets the focus, the FocusImage shall be visible. Therefore you have to configure the "EnableRendering" behavior of the "Focus" Event Handler as follows: Set the "Visible" property to TRUE and configure the scene's "FocusImage" as TargetNode. To do this, click the magnifying glass icon and selecting the "FocusImage" in the Choose Item dialog.

As soon as the MainItem loses the focus, the FocusImage shall be made invisible again. Therefore you have to configure the "EnableRendering" behavior of the "FocusLeave" Event Handler as follows: Set the "Visible" property to FALSE. The scene's "FocusImage" has to be configured as TargetNode similar to the steps above.

If you run CGI Player and click on a list item, an orange highlight should indicate that this item is in focus.

Sub-List Handling behaviors

Next, we will set the behaviors so that when a Device entry item ("MainItem") is clicked, a sub-list containing buttons will be visible. These buttons are for connecting/disconnecting the phone device to another.

Drag an "Event Handler" behavior (under Behaviors > Control) onto the "MainItem" Group Node. Then, add a "Check Logic Condition" to the Condition of this Event Handler since we want to put 2 conditions together. Under the "Check Logic Condition" add a "Check Click" condition and another "Check Key Input" condition.

The "Check Key Input" condition, checks if the enter key is pressed. Therefore the KeyCode property will be set to "Key_Enter".

Add a "Send Value as Event" behavior to the "Actions" section of the "Event Handler".

For this action behavior, we want to send a boolean value to the Sub-List as a signal that it should toggle its visibility. So please set the properties of "Send Value as Event" behavior as follows:

The Sub-List control will be the one to receive the boolean value. So let's add a Value behavior to the Sub-List control.

The value that will be sent to the Sub-List control will be of type "Bool", so the Variant type of the Value behavior has to be changed to "Bool" as well:

To configure the action that is performed when the visibility of the Sub-List is toggled, we have to add an "Action on Value" behavior to the Value behavior's receivers.

Only if the value received from "MainItem/Send Value as Event" is TRUE, an action (which will be defined in later steps) shall be performed. Therefore, we will add a "Check processed Value" condition and configure its properties as follows.

The action that shall be performed is a "Set Control State" behavior, which will actually enable the Sub-List when the condition above is met. Please drag it onto the Actions part of the "Action on Value" behavior and configure it as depicted below.

Try to run your solution in the CGI Player. When you click a main item in the list, the sub-list should appear. When clicking it a second time, it will disappear again.

Copy and paste the "MainItem" Group nodes and Sub-List nodes onto the ListContentGroup to create 4 more instances.

Make sure to update the "Send Value as Event" behavior's "TargetNode" property for each MainItem so that it will enable/disable the appropriate sub-lists.

As final step, set the Text of the first 2 list items as "Phone(Private)" and "Phone(Work)" and the last 3 items as "New Device".

You have finished the (Phone Connection) Options Scene tutorial. Generate an asset file as described at the end of Step 1. Load the generated asset into the Player and select the Options scene. You can now play around with the controls. Turn the Dial to select the type of Connection. Click on an item in the Devices list to make the sub-list buttons appear and disappear.
