I am new to javafx and building an java application using it with eclipse IDE. I learned how to create a main fx class and user interface with Scene builder. The main problem is i dont know how to get the user input (from the text field or from text area ) and display that text on console output or save that text into database after clicking 'save' button.
i want to know how can do above tasks using controller class in eclipse.
Any help would be appreciated and Thanks in advance.
I advise you first to learn the JavaFX without (FXML/Controller) and for your question :
//Event when button clicked
yourButton.setOnAction(evt->{
//display the text of your textField on the console
System.out.println(yourTextField.getText());
});
As for the Button with a Controller, you have to separate your program into two parts (View FXML |Controller java ). The official documentation explains it very well here, good luck !

I have been working on a libGDX project and was wondering if I could create a login screen with the use of some kind of text inputs. I have been looking all around for text input fields, but the only one I can seem to find are those that pop up, which I don't really want to use.
My project is a desktop game only and uses the screen implementations combinede with a game super class.
Is there any other way to get text input inside the window, so not as a pop up?
As said in the comment, the right way to make a login screen is to use Scene2d.ui and its TextField. Check out the Scene2d.ui wiki page and Skin Composer to get going.
I am coding a small script and stuck on this issue. This is my scripts screenshot.
In ... button it should be automaticly open the browse and the user can select the directory.
In addition If the user click the + Button , the script should create a new path place and the user can select the second path. The problem is how can I add the second or third path place to the gui without damage general view. Like Show Me button has to always seems in gui.
For this problem what is your advice ? Should I use first JScrollPane and then Jtree? or more easy way?
I need your helps and some tricks.
Thanks in advance.
hello I have a basic Java ability when it comes to writing code and creating such things as calcs and booking system, I am wanting to use the Desktop application in netbeans for a more professional look but I carnt manage to switch between visual forms i have created using buttons, in vb I would just set the form as me.visible(False) and Form2.visible(true). Any ideas guys thanks
Well it is very similar in Java too instead of typing
MyForm().visible(true)
Use
MyForm().setVisible(true);
Basically if you clicked a button and you wanted a new form to be displayed it would look something like
private void jButton1ActionPerformed(ActionEvent evt)
{
new TestForm().setVisible(true);
}

Create a GUI with controls to collect the data you specified. Create a class to generate the XML output. Call this class.
To build a Swing GUI, you start with a JFrame.
Within this JFrame, you have a master JPanel.
The attributes will each have JLabel components and JTextField components. You will use a layout manager to arrange the label and text field components.
You have a JButton so that the user can tell your program that she's entered all of the attributes.
You should be able to look up all these Swing components and build a GUI.
Then, as jzd said, you create a class to generate the XML output and call this class from the GUI.
i have created a input form using Netbeans IDE containing a button and a Textarea.
if i click a button it should call output.java program where the main part of execution resides and it should display the output in the TextArea created in the input.java.
Am not getting the output in TextArea..the reason is my output.java program cudnt identify the textarea.
but am getting output in window output console.please help me overcome this problem.thanks in advance
That's because you're doing it all wrong. The textarea is in a different process so you need to capture the output of the other program yourself.
Try passing a reference of the JTextarea in question to the output.java as a Constructor or method argument.
