Cannot switch to a different dialog

Question

Hello.

I'm trying to implement a touch handler that when pressed a new dialog is opened and the current one is closed using the SwitchToDialog method.

This is my current setup:

This is the 'main' dialog, that is, the one that should appear first. The gear icon and the touch event handler that is on top of it are what I want to press in order to get to the new dialog.

The slot brick is programmed with the following code:

if ( Touch_SettingsIcon )
{
  SwitchToDialog( ConoxInfo, null, null, null, null, null, null, null, null, null, false );
}

 

This is the dialog that I want to change to:

 

However, I get this error:

 

What am I doing wrong? I feel like I am very close.

Thank you.

Hello,

as the error message explains, the identifier ConoxInfo is not existing. If you want to switch to an instance of the class Application::ConoxInfo, you need to create the instance first:

SwitchToDialog( new Application::ConoxInfo, ... );

There is another problem in your actual project. The gear icon is found in the Application component and according to your description you want to switch from the Application component to the ConoxInfo component. Application component, however, acts as the root object of the entire application. You can't hide nor dismiss it. Therefore, you will need a further component, e.g. Main. Then you can switch between Main and ConoxInfo as demonstrated above.

If you don't plan to use any animations while switching the dialogs, you can also simplify the implementation by using the convenience property ActiveDialogClass available in the Application component (see also Simplified approach to handle top-level dialogs (switching screens)). All you need to do then, is to initialize the property with the class name of the component you want to present as dialog, e.g.:

// Just switch to conox info dialog
rootthis.ActiveDialogClass = Application::ConoxInfo;

...

// Later switch to Main dialog
rootthis.ActiveDialogClass = Application::Main;

I hope it helps you further.

Hello Paul, thanks for your answer.

Following your first suggestion:

There is another problem in your actual project. The gear icon is found in the Application component and according to your description you want to switch from the Application component to the ConoxInfo component. Application component, however, acts as the root object of the entire application. You can't hide nor dismiss it. Therefore, you will need a further component, e.g. Main. Then you can switch between Main and ConoxInfo as demonstrated above.

How can I implement the switch from the root component to, say, the suggested Main dialog where the gear icon is located?

I want to do that automatically as soon as the development board gets booted up.

 

Thank you kindly for your help.

Hello,

when editing the Application component, initialize its property ActiveDialogClass with the name of the GUI component Application::Main. For this purpose, first ensure you are editing the Application component. The select in Inspector the member this representing the actually edited class. Then the property ActiveDialogClass appears in Inspector and you assign a value to it:

Just in the moment when the value is assigned, the component appears as Dialog:
