kotlinlang #tornadofx

Ah, well. Never mind. After googling a bit I found https://github.com/edvin/tornadofx/issues/226, and was able to figure out what I needed to do. I don't suppose there are any other examples of custom dialogs around anywhere, are there?

The Kotlin runtime in Gradle might be ready to update. The message is still fairly cryptic for what you need in the end: ext.kotlin_version = '1.1.50'

I updated TornadoFX to Kotlin 1.1.50 now 🙂

1.1.4-3 to 1.1.50 is quite a leap.

I guess they got tired of the

-rev

versions and opted for

1.1.51

instead of

1.1.5-1

etc.

Actually, the versioning change was to satisfy NPM 🙂

@thomasnield commented on @thomasnield’s file https://kotlinlang.slack.com/files/U0HUJ25V1/F78S8CAEA/Untitled.md: I implemented some major changes to the TornadoFX-Guide on a

restructure

branch. Essentially I've divided the book into two sections: Part 1 and Part 2.

Part 1 is the core features of TornadoFX and reads sequentially like a book. Part 2 covers disparate topics that don't follow any order, and acts more like a Wiki or Appendix.

If you guys have any feedback please let me know. Edvin likes the new structure, and I'll let him make the final call to do the merge.

hm, do you guys know if I should be using ViewModels or ItemViewModels for simple POJOs to bind to UI fields?

jelloranger

09/25/2017, 3:55 AM

I've seen some examples using both

jelloranger

09/25/2017, 3:57 AM

and another question sort of along those lines, how do I bind a radiobutton in a ToggleGroup to a field? For example, I have 3 radio buttons, and I want each to bind to 1 enum value

jelloranger

09/25/2017, 4:15 AM

For textfields it's relatively simple, I can bind it like textfield(model.stringField). but I need to somehow bind an entire togglegroup to an enum (i.e. model.enumField) and somehow say which radiobutton corresponds to which enum value

@edvin Hi Edvin, Is there any way to customize keyboard navigation in tableview

devanand

09/25/2017, 4:19 AM

I want to handle the navigation from the tablecell like as below

Copy code

textField.addEventFilter(KeyEvent.KEY_PRESSED, event -> {
            if (event.getCode() == KeyCode.ESCAPE) {
                textField.setText(converter.toString(getItem()));
                cancelEdit();
                event.consume();
            } else if (event.getCode() == KeyCode.RIGHT) {
                getTableView().getSelectionModel().selectRightCell();
                event.consume();
            } else if (event.getCode() == KeyCode.ENTER) {
                int col = getTableView().getFocusModel().getFocusedCell().getColumn();
                if ((col + 1) == getTableView().getColumns().size()) {
                    int row = getTableRow().getIndex() + 1;
                    getTableView().getSelectionModel().select(row);
                    for (int i = col; i > 0; i--) {
                        getTableView().getSelectionModel().selectPrevious();
                    }
                } else
                    getTableView().getSelectionModel().selectRightCell();
                event.consume();
            } else if (event.getCode() == KeyCode.TAB) {
                getTableView().getSelectionModel().selectRightCell();
                event.consume();
            } else if (event.getCode() == KeyCode.LEFT) {
                getTableView().getSelectionModel().selectLeftCell();
                event.consume();
            } else if (event.getCode() == KeyCode.UP) {
                getTableView().getSelectionModel().selectAboveCell();
                event.consume();
            } else if (event.getCode() == KeyCode.DOWN) {
                getTableView().getSelectionModel().selectBelowCell();
                event.consume();
            }
        });

Hm, any idea on how to solve this overload resolution ambiguity error when trying to add a validator to a checkbox?

-.kt

jelloranger

09/25/2017, 5:27 AM

It says there's a validator method on both

Labeled

and

CheckBox

, and it looks like

CheckBox

inherits from

Labeled

jelloranger

09/25/2017, 5:27 AM

I know in this simple example I could just say

required()

but I'm doing something a bit more complex in my app

@edvin I am using ControlsFX autoCompletionBinding in a TextField.

Copy code

val under = textfield()
TextFields.bindAutoCompletion(
                            under, FXCollections
                            .observableArrayList(
                        GroupsComboItem("some_id", "some_name", "some_parent")))

data class GroupsComboItem(val id: String, val label: String, val parent: String?) {
    override fun toString(): String {
        return label
    }
}

I want to get the id which I passed on a button click. If I use a combobox instead, I can just simply write

combobox.selectedItem.id

@jelloranger Try disambiguating the validator by specifying the parameter explicity with a "vc : Boolean? -> A test program follows

@devanand See if the following program helps you. I created my own cellFactory so that i could put an event filter (not handler) on the editing TextField of the TableCell. This way, I can intercept the arrow keys and override the default behavior which is to move the cursor within the TextField when using the arrow keys.
