Re: how to reference to other topcomponent

Hi Peter,


This is not a good design choice.   The SymbolWindowTopComponent should be listening for changes and updating itself, instead of making a member variable public and allowing other classes to update it.   For a modular design it is best to use something called a 'lookup'.

Subject: [nbdev] how to reference to other topcomponent

now i got a super simple solution, create a Global class:

public class Global {
        public static SymbolWindowTopComponent window;
}

then self register the window in the static variable:

Global.window = this;

finally in other window, i can:

Global.window.jLabel1.setText("peter");

BUT IS IT NORMAL? ANY HIDDEN DISADVANTAGE FOR THIS METHOD?

thanks
