TableView with custom type combobox - combobox

Question

I would like to create a TableView where its columns have reference to type:
private Indicators(String tl, WindowsItem chrt, String pne, Boolean sel) {
this.tool_col = new SimpleStringProperty(tl);
if (chrt == null) {
this.chart_col = new SimpleStringProperty("");
} else {
this.chart_col = new SimpleStringProperty(chrt.toString());
}
this.pane_col = new SimpleStringProperty(pne);
this.on_col = new SimpleBooleanProperty(sel);
this.chrt = chrt;
}
public String getTool() {
return tool_col.get();
}
public void setTool(String tl) {
tool_col.set(tl);
}
public WindowsItem getChart() {
return chrt;
}
public void setChart(WindowsItem _chrt) {
System.out.println("Indicators::setChart "+chrt.toString());
chrt = _chrt;
}
public String getPane() {
return pane_col.get();
}
public void setPane(String pne) {
pane_col.set(pne);
}
public Boolean getOn() {
return on_col.get();
}
public void setOn(boolean sel) {
on_col.set(sel);
}
public SimpleBooleanProperty onProperty() {
return on_col;
}
public SimpleStringProperty toolProperty() {
return tool_col;
}
public SimpleStringProperty chartProperty() {
return chart_col;
}
public SimpleStringProperty paneProperty() {
return pane_col;
}
}
I have a
private TableView<Indicators> tableviewIndicators;
In this column
private TableColumn<Indicators, WindowsItem> tablecolumnFrame;
public static class WindowsItem {
InternalWindow chrt;
private WindowsItem(InternalWindow _chrt) {
chrt = _chrt;
}
public String toString() {
return chrt.getTitle();
}
}
I would like to have a combobox or choicebox where every item type is
WindowsItem
How can I accomplish this?
I have tried this code
tablecolumnFrame.setCellFactory(new Callback<TableColumn<Indicators, WindowsItem>, TableCell<Indicators, WindowsItem>>() {
#Override
public TableCell<Indicators, WindowsItem> call(TableColumn<Indicators, WindowsItem> param) {
TableCell<Indicators, WindowsItem> cell = new TableCell<Indicators, WindowsItem>() {
#Override
public void updateItem(WindowsItem item, boolean empty) {
super.updateItem(item, empty);
if(empty){
return;
}
if (item != null) {
//final ChoiceBox<WindowsItem> choice = new ChoiceBox<>();
final ComboBox<WindowsItem> choice = new ComboBox<>();
int itemsInTab = chartsInTab.getChildren().size();
InternalWindow winItem;
for (int i = 0; i < itemsInTab; i++) {
if (chartsInTab.getChildren().get(i) instanceof InternalWindow) {
winItem = (InternalWindow) chartsInTab.getChildren().get(i);
choice.getItems().add(new WindowsItem(winItem));
//choice.getItems().add(winItem.toString());
System.out.println("winItem.toString() "+winItem.toString());
}
}
But it return this error
SEVERE: javafx.scene.control.Control loadSkinClass Failed to load skin 'StringProperty [bean: TableRow[id=null, styleClass=cell indexed-cell table-row-cell], name: skinClassName, value: com.sun.javafx.scene.control.skin.TableRowSkin]' for control TableRow[id=null, styleClass=cell indexed-cell table-row-cell]

Answer 1

You can try this:
private TableColumn<Indicators, WindowsItem> tablecolumnFrame;
and
public static class Indicators {
private final SimpleStringProperty tool_col;
private final SimpleStringProperty pane_col;
private final SimpleBooleanProperty on_col;
private final SimpleObjectProperty<WindowsItem> chrt;
private Indicators(String tl, WindowsItem chrt, String pne, Boolean sel) {
this.tool_col = new SimpleStringProperty(tl);
this.chrt = new SimpleObjectProperty<>(chrt);
this.pane_col = new SimpleStringProperty(pne);
this.on_col = new SimpleBooleanProperty(sel);
}
public String getTool() {
return tool_col.get();
}
public void setTool(String tl) {
tool_col.set(tl);
}
public WindowsItem getChart(){
return chrt.getValue();
}
public void setChart(WindowsItem _chrt) {
chrt.set(_chrt);
}
public String getPane() {
return pane_col.get();
}
public void setPane(String pne) {
pane_col.set(pne);
}
public Boolean getOn() {
return on_col.get();
}
public void setOn(boolean sel) {
on_col.set(sel);
}
public SimpleBooleanProperty onProperty() {
return on_col;
}
public SimpleStringProperty toolProperty() {
return tool_col;
}
public SimpleObjectProperty<WindowsItem> chartProperty() {
return chrt;
}
public SimpleStringProperty paneProperty() {
return pane_col;
}
}
be careful to:
public SimpleObjectProperty<WindowsItem> chartProperty() {
return chrt;
}
in your previous code was:
public SimpleStringProperty chartProperty() {
return chart_col;
}
this is the reason for the
