Hi Chand Bhadaniya,
if you want to have variables (e.g. to store some settings) that should be accessible from different components within your applications, you can put these variables into a separate class and create an autoobject of this class (e.g. Application::Settings). Instead of variables you can use properties - then you can additionally use notifications and observers to inform your GUI components about changes within the settings class.
Hi, please try the following:
Add a new class to your unit (e.g. Application) and rename it to Settings.
Open the class Settings and add your Properties to the class (e.g. Counter, Volume, ....).
Now, create an autoobject of the class Settings within the unit Application and rename it to GlobalSettings.
Within your application class, create a variable, set the type to Application::Settings and set the initialization value to Application::Globals. This ensures that your global class is kept within the memory the whole runtime of the application.
Now you can access your global properties from everywhere in the GUI application, e.g.
Application::GlobalSettings.Volume = 5;
Application::GlobalSettings.Counter = 0;
Hope this makes it more clear now....
