"GUI Application X" is calling another "GUI Application Y", In Cavas it shows "GUI Application Y"

Question

Hello

I have a GUI Application, say it X and I have implemented a splash screen as another GUI Application, say it Y.

X is a Main screen for me, Y suppose to appear for sometimes and leaves back to X. Also in prototyper it works fine.

Now the problem is - In canvas I see Y , I could not able to edit/modify X.

Is this a bug or it is as expected ?

Ans: ??

to get rid of this problem, I am using "$if !$prototyper , $endif".

I could not able to find difference between "Empty GUI Application" and "Empty GUI Component", Both are working same/similar manner. What is the actual difference ?

Ans: ??

In what case should I use "Empty GUI Component" and in what case I should use "Empty GUI Application" ?

Ans: ??

I need Expert advice, please help.

Hi Maharaja,

regarding the difference between regular component and application component please see the article Creating the application component.

In principle, in every Embeded Wizard project you have several GUI components (buttons, sliders, screens, alerts, message paneles, ...) and one (single) application component. The application component represents the entire screen. As such it is unique. It also manages the screen update and event dispatching.

I suppose, you have tried to manage several application components within your project. Except special application cases (e.g. devices with multiple LCD displays, etc.) it is not necessary. Just manage only one application component in your project.

All other components (be it complete and complex screens or even simple buttons, sliders, etc) are even 'regular' GUI components you can create in one of the following possibe manners:

Option 1: Creating new Components.

Option 2: Creating components from templates.

Option 3: Subclassing components.

Hope it helps you. If not, please upload a simple project demonstrating the problem so we can analyze it.
