Q: Populating JavaFX ComboBox or ChoiceBox from enum

Is there a way to populate a JavaFX ComboBox or ChoiceBox with all enumerations of a enum ? Here is what I tried : public class Test { public enum Status { ENABLED("enabled"), DISABLED("disabled"), UNDEFINED("undefined"); private String label; Stat...

Looks fairly easy there, but the grass is always greener on the other side :P

@Hosch250 I mostly implemented the enum backing the combo box now, how would you go on about the conditional visibility? Does that really belong in XAML, or more in the code-behind or perhaps even in the VM?

I now ended up with having a ShowFuelCost/ShowShippingCost/ShowShippingIncluded property that has a get that checks if the ExtraCostType enum matches the respective value

And I render the items with a BooleanToVisibilityConverter on those bindings

Pushed everything as well: github.com/skiwi2/ArbitrageClient

@skiwi XAML. Did you get it?

skiwi

@Hosch250 I did it somewhat different just now

@Hosch250 Should the property binding that calculates TotalPrice not be in the model instead of the viewmodel in my case?

github.com/skiwi2/ArbitrageClient/blob/master/ArbitrageClient/…

Hosch250

@skiwi Could be.

skiwi

Since it only concerns the model and not other related parts of the viewmodel it might be better off there?

Hosch250

You can bind to items in the VM, you know.

Sure.

skiwi

As I'd also need it when calculating the total price in the model

Hosch250

The view model just provides data for the display. Theoretically, you shouldn't be doing much work there, other than calling the code for the UI actions.
