java - Is it possible to use a specific class in the javafx Dialog? -


i searching javafx joptionpane equivalent , did found great class dialog. in tutorial, tutor used : dialog<pair<string,string>> 2 string input fields , here m wondering possible use class let : dialog<product>. if possible how should write class specific pattern or plot so? thanks

yes, can that. answer basing on:

https://examples.javacodegeeks.com/desktop-java/javafx/dialog-javafx/javafx-dialog-example/

assuming product has 2 fields can passed via constructor:

string name; float price;

you can create dialog in such way:

dialog<product> dialog = new dialog<>(); dialog.settitle("product dialog"); dialog.setresizable(true);  label namelabel = new label("name: "); label pricelabel = new label("price: "); textfield namefield = new textfield(); textfield pricefield = new textfield();  gridpane grid = new gridpane(); grid.add(namelabel, 1, 1); grid.add(namefield, 2, 1); grid.add(pricelabel, 1, 2); grid.add(pricefield, 2, 2); dialog.getdialogpane().setcontent(grid);  buttontype savebutton = new buttontype("save", buttondata.ok_done); dialog.getdialogpane().getbuttontypes().add(savebutton);  dialog.setresultconverter(new callback<buttontype, product>() {     @override     public product call(buttontype button) {         if (button == savebutton) {             string name = namefield.gettext();             float price;             try {                 price = float.parsefloat(pricefield.gettext());             } catch (numberformatexception e) {                 // add log or inform user wrong price                 return null;             }              return new product(name, price);         }          return null;     } });  optional<product> result = dialog.showandwait();  if (result.ispresent()) {     product product = result.get();     // product }

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
