JavaFX 2.0 :: Abnormally Closing A Dialog With No Buttons
Apr 14, 2015
I have a Dialog with no buttons (the dialog pane contains some graphic elements which act as my buttons). I show the dialog and try to click the close window button on the dialogs title bar, and the dialog does not close! I read the docs and it appears that only dialogs that have one or more buttons can be abnormally closed (and only under certain well defined sensible conditions). How can I abnormally close a dialog with no buttons?
I want to create a button bar that is the same as the confirmation dialog button bar -- so an OK and cancel button layed out in the platform specific way, and with the same styling.
I have made some progress via a hack -- create an alert dialog, and extract the buttons in the dialog using lookupButton, and then put those buttons in a toolbar. But this doesn't necessarily get a toolbar with the buttons in the correct order. If I could get the button bar out of an alert dialog I would have a solution, but I can't see to do that.
I have a javafx class that has buttons and textfields. Here is the code for a button, and i want the button to make a new object but im having trouble setting the constructor
Label label = new Label("Type"); GridPane.setHalignment(label, HPos.RIGHT); TextField textField = new TextField();
Label label2 = new Label("First Name"); GridPane.setHalignment(label2, HPos.RIGHT); TextField textField2 = new TextField();
[Code] ....
after i create the object i will insert the object in an arraylist of person objects
Is there a possibility to use events for additional mouse buttons, like the next or previous mouse buttons, in javafx? If I use the setOnMousePressed event on a node, it only throws an event for the "PRIMARY" "SECONDARY" and "MIDDLE" buttons.
If I use this java application [URL] .... it is also possible to throw events for the next or previous mouse buttons of the mouse. But not in my javafx application.
I have an app that was working with JavaFX 2 on JDK 7 but seems to no longer work in JavaFX 8 on JDK 8. The story is that I have a ListView where I have provided my own CellFactory. Within the class that extends ListCell, in the updateItem() method, I create an HBox that contains some text and a new button.
I register an onAction() callback for the button. The end result should be a list with entries which contain buttons and when a button is clicked, the onAction() callback is invoked. However, when I run it and click the button, the callback is NOT being fired. This exact code was working on JavaFX 2 and JDK 7.
I have several Buttons wrapped into a VBox. I used setOnSwipeUp and setOnSwipeDown for up and downs the buttons. But when there is no more buttons the scroller continues but shows nothing, is empty. How do I do when there are no more buttons ignore swipe gestures?
[Java] // Menu Swipe Up menubox.setOnSwipeUp(new EventHandler<SwipeEvent>() {
I have a WindowClosing(WindowEvent e) method, but when I close my window it isn't doing anything inside the method. I am making a launcher and I want to make it so when the actual game window is closed it makes the launcher window visible again.
Java Code: public void windowClosing(WindowEvent e) { this.jf.setVisible(true); } mh_sh_highlight_all('java');
I wrote a program to transfer a file using tcp connection, where I closed socket since the receiver need to detect the end-of--file. But now I like to extend it to multiple file for which i should not close the socket until all the files are send. I can't find a way for this. So how to resolve it.
I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
if the above code is to launch another application using java then how can I close/exit the same(another) application using java code once I press the exit button of my java app.
I'm going through a file (MySQL dump) and I wish to take the SQL and create individual files for each table (as opposed to what I do now, which is just run through the whole thing).
Now, this all works fine - but what I want to do is create a separate .sql file for each table.
However, I can't figure out the best way to do this - how do I create a new FileWriter (or instance of whatever class is required) as I'm going through the while loop? That or pointing the same one to different files as I go through the loop.
It can be assumed that the file may exceed RAM - I want to do it line by line rather than slurping the entire file as a string and "cheating" that way.
There appear to be many (a bewildering amount of) I/O options and I'm just unsure.
I am modifying existing code to display graph after pressing calculate button. The graph pop ups in new controller/window. The pop up disappears after closing the application entirely. However I have trouble figuring out if it is possible to close that old/previous pop up and new pop up appears when calculate button is pressed again. Or at least reuse the pop up to display a new graph.
public class AdamCalculationApp extends AbstractCalculation { /** * Does a calculation. */ public void calculate() { // Does a calculation control.println("Adam Calculation button pressed."); double k = control.getDouble("k value"); // String must match argument of setValue control.println("k*k = "+(k*k)); control.println("random = "+Math.random());
While analyzing the thread dumps for a performance issue in our java ee web application, I see many thread dumps stuck on a closing brace of a while loop. Here is the code block of a third party library bitronix (version 1.3.3 SNAPSHOT)
public XAResourceHolderState findXAResourceHolderState(XAResource xaResource) throws BitronixSystemException { Iterator it = resources.iterator(); while (it.hasNext()) { XAResourceHolderState xaResourceHolderState = (XAResourceHolderState) it.next(); if (xaResourceHolderState.getXAResource() == xaResource) return xaResourceHolderState; } return null; }
The thread dumps indicate that many threads are stuck in RUNNABLE state on line number 07. What could be the possible reasons on why a thread could get stuck on a closing brace of a while loop? The iterator of the while loop is a custom implementation.
I configured a connection pool in tomcat 7. For every database activity I get a connection from the pool. Do I have to close the connection like other regular connection after the database operation is done? If I close the connection will it have any effect on the connection pool?
This is the code I have written so far. This program calculates tax from multiple tax payers.
import javax.swing.JOptionPane; public class CalcutateTax { public static void main (String [] args)
[code]....
The problem is I cant think how to ask the use if he wants to calculate tax due for another taxpayer. If the user says yes, keep calculating, otherwise exit from the program. And how do I keep count of how many people got their tax calculated? Say for example,
JOptionPane.showMessageDialog (null, " We calculated tax for " + xnumber + " number of people.");
This is the question asked on my assignment ask the user if he wants to calculate the tax due for another taxpayer if so, do it again.At the end of the main method, output a message in a dialog box that says: Hello, We calculated taxes for [number of taxpayers].replace [number of taxpayers] with the actual number of taxpyers you calculated taxes for.
i am using a frame over which i am loading a dialog. The singleton dialog holds a progress bar. I have created my own swing worker. i am controlling the construct method of swing worker(which functions like doInBackground method).I am trying to call hidedialog from an external file. The dialog gets stuck sometimes. How do i solve it . It works fine on win7 but fails on win8.
I am in my first Java class and this is the second assignment. I am supposed to write a program that prints a table of squares and cubes and also uses dialog boxes for the input and the output. The output should look like this:
I've figured it out but my only problem is the output dialog box displays each row individually (a new dialog box pops up for each row). How do I get it to display the whole table???Here's my code:
Java Code: import java.util.Formatter; import javax.swing.JOptionPane; public class Homework2 { public static void main(String[] args) {
I have managed to write the program where the user can input kg and the formula converts it into lbs. I have also written a program where I can get a dialog box to appear to ask the user to input the kg, but I can't figure out how to combine the two.
This program allows the user to input the kg, it converts it to lbs and then displays the output:
import java.util.Scanner; import javax.swing.JOptionPane; //creates a dialog box
public class convert { public static void main(String args[]) {
[Code] ....
This program only brings in the first variable and the initial dialog box:
import java.util.Scanner; import javax.swing.JOptionPane; //creates a dialog box public class KgLbs { public static void main(String args[]) {
[Code] ...
I have attached the actual assignment and what the program should look like.
The below program ask the user to enter the value of x 1 , Y 1 and radius in separate boxes , What would look nice is if the user can Enter the Value X ,Y and radius in the same box.
import javax.swing.JOptionPane; public class C3E29GeometryTwoCircles { public static void main(String[] args) { // Ask the user to enter the x1 coordinate. String strNumber = JOptionPane.showInputDialog("Enter the value of x1 coordinate " ); double x1 = Double.parseDouble(strNumber); strNumber = JOptionPane.showInputDialog("Enter the value of y1 coordinate " ); double y1 = Double.parseDouble(strNumber);
I have to return the minimum and maximum value entered by the user, so far the program returns the maximum but the minimum stays at 0. I assigned 0 to the min and max variables. I believe that is part of the problem, but why do I get an accurate answer on the max if both variables are assigned to 0?
int min = 0; int max = 0; int option = JOptionPane.YES_OPTION; while ( option == JOptionPane.YES_OPTION){ String dataString = JOptionPane.showInputDialog("Enter an integer"); int data = Integer.parseInt(dataString); if ( min > Integer.parseInt(dataString)) min = Integer.parseInt(dataString); if ( max < Integer.parseInt(dataString)) max = Integer.parseInt(dataString); option =JOptionPane.showConfirmDialog(null, "Continue?"); } JOptionPane.showMessageDialog(null, "Minimum: " + min + " Maximum: " + max); }
I have an application that has a text field I want to use Jfilechooser to save or save As the data.
If the file already exisits i want the end user to be able to hit save without the dialog box popping up asking for a file name folder etc, like it would in MS Word etc..
