Following code works, but when I change from Male to Female or vice versa, cbSpouse gets new Items loaded. Correct data gets loaded. But the issue is, if I click on the down arrow in cbSpouse, I need to wait for a few minutes before I see the drop down. There is no database interaction, all necessary data is already sitting in Observable list.
ObservableList<String> GenderOptions = FXCollections.observableArrayList("Male", "Female");
cbGender.getItems().clear();
cbGender.setItems(GenderOptions);
cbGender.setVisibleRowCount(GenderOptions.size());
cbGender.getSelectionModel().selectFirst();
cbGender.valueProperty().addListener(new ChangeListener<String>() {
#Override
public void changed(ObservableValue ov, String t, String t1) {
System.out.println("Change Listener for cbGender - oldValue "+t+" new value"+t1);
if ((t1.equals("Male")) || (t.equals(null))) {
cbSpouse.setItems(myMainApp.getFemaleSpouses());
if (thisPerson.getPhoto() == null) {
thePicture.setImage(defaultMale);
}
} else {
cbSpouse.setItems(myMainApp.getMaleSpouses());
if (thisPerson.getPhoto() == null) {
thePicture.setImage(defaultFemale);
}
}
cbSpouse.getSelectionModel().selectFirst();
}
});
//
There are about 300 items in myMainApp.getMaleSpouses() which actually returns the Observable list.
Can someone help me?
Thanks in Advance.

Here is the smaller version, which works nicely. Just keep changing the Gender and click on Spouses, new list appears.

In this example data is Hard coded and in Main.java, but in the other version, it is loaded from
static private javafx.collections.ObservableList Fathers = javafx.collections.FXCollections.observableArrayList();
static private javafx.collections.ObservableList Mothers = javafx.collections.FXCollections.observableArrayList();
loading the ObservableList from database occurs much earlier, before cbGender valueProperty Changed.

I'm new in JavaFx. I have a GridPane created in FXML. I want to style that GridPane as the following image. I have tried with the following answers and tried with more CSS elements. But none of these helped me to do this.
JavaFX CSS class for GridPane, VBox, VBox
Center children in GridPane using CSS
Adding borders to GridPane JavaFX
And also am I using a wrong approach? Can I achieve this using GridPane or will the TableView is easy to this?
I think you can use a TableView control. You can use the following code to start with:

Best regards
Use the two-parameter renderImage(page, scale) method. 1 is the default scale and is 72 dpi, 4 is 288 dpi which is usually pretty good. So I suggest you start with scale 4, and in a later step you increase when zooming (note that rendering may become slower with higher resolutions).
So a code example for your code would be
pageImage = renderer.renderImage(pageNumber, 4);

Try renaming your getter methods from getprocessIDP and getstatusCodeP to getProcessIDP and getStatusCodeP respectively (note the capital 'S' and 'P'). To avoid problems like this in the future it's a good habit to generate getters, setters and constructors with the IDE instead of doing it manually.

Please help, i am done everything to change the code but nothing is a really success, i recur to this site because , the people here are specialist in what they do, so why i am asking its not to much.
this is my case , in my code i am calling through a query all the data in my table, searching a particular name or lastname, so when i run the code the method seleccionapellido is giving me an error, the console show "index 2 out of range" this doesn't ocurr in my first method seleccionanombre, that's the rare thing, so why this is happening in one method, and in the other just the code crash, this methods have the same invocations.

i dont know what is happen whit the method seleccionapellido, its has the same thing that the method seleccionnombre, if someone can help me, it would be the greatest thing right now.
I Just Change the SQL Server Driver to the last Version, and that was it, and later Clean up the project in Eclippse.
i need to make gui who will display all objects from database with auto increment ID. When we will click on some object,and click on edit button,we can edit data like name etc. When we will end change our object,we must click on save button who need update data in database. How i can add an autoincrement ID to database? (i've created one,but without ID) when i added an id to database,i can't display any data on receiveCats.fxml. Second issue that i have is to this save button. How i can push edited data to object in database?

Error that i received:
Can't select data from Cats
no such column: 'ID'
There's a lot of code here, and you seem to be asking multiple things. I'll just answer the first (in general you should address one issue at a time in one question at a time, and you should create a complete example that does nothing else except demonstrate the problem at hand).
Your create statement defines a primary key column Cat_id:
String createCats = "CREATE TABLE IF NOT EXISTS Cats (Cat_id INTEGER PRIMARY KEY AUTOINCREMENT,name varchar(255), race varchar(255), gender varchar(255), coat_color varchar(255),age int)";
however when processing the query, you try to retrieve a value from a column called ID:
Integer ID = resultSet.getInt("ID");
You need to make these match, e.g.
Integer ID = resultSet.getInt("Cat_id");
Make sure your database has auto-increment enabled. then just insert data into your database with sql "INSERT command" and later on display it with sql "SELECT command". Make sure to link your sql commands to your gui buttons in the controller.
