JavaFX 2.0 :: Unable To Change Textfield Value
Jun 8, 2014
I am having a small JavaFX program where I try to set a value to TextField. Below is the part of FXML file and highlighted is the Textfield ....
fxml file
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="185.0" prefWidth="598.0">
<children>
<TextField fx:id="actiontarget" editable="true" layoutX="146.0" layoutY="73.0" prefWidth="198.0" text="" />
[Code] ...
I want to display a string value to that text field.
So, I am using that fxid (actiontarget)
But actiontarget.setText (pathofFile) is not working .
Nothing displays and no value sets for the Text field.
How can I set value in that text field through above code.

When in panel2 i type something in the search bar and then i move mouse cursor to panel1 and try to edit a JTextField input for example as in the picture 0.0 nothing happens but the mouse cursor is correctly show up in the JTextField.. What seems to solve the problem is to click anywhere outside of the application window.. but of course this is not a solution !

I have tried different sizes for the 'TextField' but when I change the size, the position changes instead of the size itself.

I have a list of Row objects and want to listen to changes in the name property of a Row object.
public class Row implements Serializable {
private final SimpleStringProperty name = new SimpleStringProperty(this, "name", "");
public Row() {
this("");
}
public Row(String name) {
this.name.set(name);
[Code] ....
I would expect to be notified 4 times. Line 23: Added, Line25, 26, 27: Update
But there are only 2 change events. For Line 26 and 27 there is no change event.

I change TreeTableColumn.text but I got a Exception
Exception in thread "JavaFX Application Thread" java.lang.ClassCastException:
javafx.scene.control.TreeTableColumn cannot be cast to javafx.scene.control.TableColumn
at com.sun.javafx.scene.control.skin.TableHeaderRow$10.invalidated(TableHeaderRow.java:277)
so I check TableHeaderRow . I find this method
private final InvalidationListener columnTextListener = new InvalidationListener() {
@Override public void invalidated(Observable observable) {
TableColumn<?,?> column = (TableColumn<?,?>) ((StringProperty)observable).getBean();
CheckMenuItem menuItem = columnMenuItems.get(column);
if (menuItem != null) {
menuItem.setText(getText(column.getText(), column));
}
}
};
why don't they use this
TableColumnBase<?,?> column = (TableColumnBase<?,?>) ((StringProperty)observable).getBean();

I have noticed a strange behavior of Combobox element. The number of visible rows is not the same established by setVisibleRowCount() method. It happens when changing the items list dynamically. The following example reproduces it. I think it is Javafx 8 bug. I have tried unsuccessfully to trigger some event indirectly to refresh the combobox drop down.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ComboBox;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class TestComboBox extends Application {
private int count;

So it seems to reason that many JavaFX applications will want to dynamically change CSS styles. Is the best way to do this via the <node>.getStyleClass().add("classname")? The underlying data structure is an observable list. So lets say one has 5 styles that simply change the fill color of a circle to 5 different colors respectively. So if I have a condition in which I want to dynamically apply 1 of these 5 styles, the way I currently do this is by defining all 5 styles as strings in a list using a static initializer, then I call <node>.getStyleClass().removeAll(list), then getStyleClass().add("classname"). I do this to avoid adding the same style over and over and inflating the underlying list. Is this the correct way to manage dynamic CSS styles?
So I know there is a few different way to implement a splash screen. My app has definitely gotten larger over the last few months of development and I have noticed there is about a 5 second delay between when I run the application to when I see the main stage. I was thinking a splash screen would be nice to fill this time period. I have not had time to prototype using a Preloader and I fear that using an alternate, lightweight stage on startup would still take too long of a delay. I was actually thinking that using the nice and simple JVM argument "-splash:<image name>" would be simple, easy and effective. Unfortunately when I try to do this, the splash screen comes up but never goes away.

I try to bind the text-property of a selected cell of a TreeView to a label. So if the user click on a cell in the treeview the label should show the cell text. Now I am quite confused about the options I got to do so. Should I use label.textProperty().bind( ... ??? ... ) The treeview.onMouseClicked()property? or something different?

I am currently making a video player which allows users to open/play videos which are stored on their computer. I am using JavaFX for this.My problem, is that sometimes when I click the button to load a video, a java.util.ConcurrentModificationException is raised. Other times, it's perfectly fine.I put the calls to .loadAndPlayMediaA() and .prepareMedia() (see below) inside a .runLater(Runnable) to try to prevent this, but it has not worked. My Code (below) is called by a listener on a button, "testButton". I have a class called JfxMediaPlayer which holds the method loadAndPlayMediaA(), and a class called MixingDeck which holds the method prepareMedia()
testButton.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent arg0) {
Platform.runLater(new Runnable(){
@Override

I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField. I have made multiple tweaks, but think maybe my case statement is the problem?We did a calculator application in the class, so I have based my code off of that. Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.
public void actionPerformed(ActionEvent e) {
//test for button clicks
foundKey = false;
//search for clicked key
for (int i=0; i<keys.length && !foundKey; i++)
