How can shift my tab view from one to another in JavaFx - javafx

Question

I am doing a JavaFx project . I have a table view which is populated by few names (e.g. BG Manager , User Management , Find Acl , ....) . Each time I click on each one of those names (or each row of that table ) it will open a new tab which is again populated with the information I set out earlier inside . Here is an example function that being called once I click on a row with the name of BG Management :
private void callBGManager(){
try {
Tab tab = new Tab ();
FXMLLoader bgm = new FXMLLoader(getClass().getResource("/views/BGMWindow.fxml"));
BGMController bgmc = new BGMController(_session);
bgm.setController(bgmc);
Parent root = bgm.load();
for (Tab tabs : TabPane1.getTabs()){
if (tabs.getText().equals(ListView1.getSelectionModel().getSelectedItem())){
SingleSelectionModel<Tab> selectionModel = TabPane1.getSelectionModel();
selectionModel.select(tab);
return;
}
}
tab.setContent(root);
tab.setText(ListView1.getSelectionModel().getSelectedItem());
tab.closableProperty().set(true);
TabPane1.setTabClosingPolicy(TabPane1.getTabClosingPolicy().SELECTED_TAB);
TabPane1.getTabs().add(tab);
SingleSelectionModel<Tab> selectionModel = TabPane1.getSelectionModel();
selectionModel.select(tab);
}catch(Exception e){
e.printStackTrace();
}
}
There is no problem in the compilation or operation of this code as it works well . Here is the scenario for the better understanding of the situation . I have lets say 5 rows in my list and every time I click on each if it's not already opened it will show up and if it's already open nothing happens . Lets say I am already in another tab view and the BG Manager is already open . How can I shift to BG Manager once I click re-click on it :)

Hello Danial u can use (row)cell.setUserData(); and by deafult set for each true value. And onClick on this row(cell) you should to check this data (row)cell.getUserData(); and if it is true than change it to false and open window in another case do nothing.
EXAMPLE:
table.setRowFactory( tv -> {
TableRow<MyType> row = new TableRow<>();
row.setOnMouseClicked(event ->{
boolean result = (boolean) row.getUserData();
if(result){
row.setUserData(false);
//There will be your method to open new window
methodToOpenNewWindow(row);
}else{
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.setTitle("Information");
alert.setContentText("This entity already was opened.");
alert.show();
}
});
return row ;
});
In method methodToOpenNewWindow on close window set row userData back to true .
