JavaFX 2.0 :: Progress Indicator In ListView Has Border And White Background?
Dec 1, 2014
If I "embed" a ProgressIndicator inside a ListView it has an ugly border and a white background. It looks like there's a TextField below the ProgressIndicator.
Why does it behave like that and how to solve it so that the progress indicator is transparent.
Here is the code, I just wanted to draw a simple yellow rectangle in white background...
import javax.swing.*; import javax.swing.event.*; import java.awt.*; import java.awt.event.*; public class NewEmpty extends Jframe { Rectangle test = new Rectangle(100,100,100,100); public NewEmpty()
[Code] .....
Errors in the compiler ( i think there's something wrong with that Jframe)
init: deps-jar: Compiling 1 source file to C:Users****Gametestbuildclasses C:UsersMarcoGametestsrcgametestNewEmpty.java :6: error: cannot find symbol public class NewEmpty extends Jframe {
I am unable to clear disappear the background of .png image added in a translucent JPanel. I have tried it using JLabel but the image added is with white background. How can i get rid of this white background...
import javax.swing.*; import java.util.*; import java.awt.*; public class HomePage { JFrame frame; JPanel pnl1, pnl2, pnl3; JLabel lbl;
I have a ListView with ListCells that are complicated things containing other nodes. I want to turn of ListView selection behavior (so not allow selections) without turning of events to the ListCell nodes in the ListView.
I can't figure out how using binding on selectionModelProperty in a ListView that is using MULTIPLE selection model. I want bind my bean in which I've a list of item A and the selection of that items into the List.
I have a selection listener attached to a TreeView as shown below
treeView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<TreeItem<Pair<VideoSourceType, String>>>() { @Override public void changed(ObservableValue<? extends TreeItem<Pair<VideoSourceType, String>>> observable, final TreeItem<Pair<VideoSourceType, String>> oldValue, final TreeItem<Pair<VideoSourceType, String>> newValue) { // do something treeView.getSelectionModel().clearSelection(); } };
What I want to do is to "do something" and then clear the selection so that it can be selected again. However, I cannot re-select the same item from the TreeView until I first select a different item.
I want to synchronize a List<String> with the selected items of a ListView. In the real project, I want to synchronize the selected items of a TreeView and the selected images of a galery (custom control).
In most cases, the program works as expected but sometimes there are some issues.
- For example, when I launch the application and select all the items with Ctrl-A, the event { [One, Two, Three] added at 0, } is fired so the list of strings contains incorrectly 4 elements [One, Two, Three, One].
- Another example, when selecting all the items (with Shift+End), two events are fired { [One] removed at 0, } and { [One, Two, Three] added at 0, }, that's correct. But when I remove the last element with Shift-Up, 3 events are fired { [Two] removed at 1, }, { [Three] removed at 2, } and { [Two] added at 1, } and an exception is thrown:
java.lang.IndexOutOfBoundsException: toIndex = 3 at java.util.ArrayList.subListRangeCheck(ArrayList.java:1004) at java.util.ArrayList.subList(ArrayList.java:996) at com.sun.javafx.binding.ContentBinding$ListContentBinding.onChanged(ContentBinding.java:111)
I'm trying to add filtering content in ListView by selected date from DatePicker. Every position(movie) has it's emission date saved, so when you choose date that you're interested in, it will show just matching titles. I was trying to use this solution:
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 only want the context menu to be showen if the user is clicking on an actual listview item, not if they click anywhere else in the listview. I know this is possible and I found answers to similar problems, but in the end they didn't provide enough infomation for me to solve my issue. I found this example on how to do it with a list view containing String objects, but what if my list view contains another object, in my case a wrapper class? I have a wrapper class to keep track of the key, but I only display the value variable in the listview, through calling the toString method. So the cells still contain a wrapper.
class Wrapper(int key, String value) { .. } public String getValue() { return value; } public SimpleStringProperty getValueAsProperty() { return new SimpleStringProperty(value); } public String toString() { return value; }
[Code]....
But line 05 gives me a NullPointerException, why? I do this after I've set the items of the list view by doing listView.setItems(..).
public class Person { private SimpleStringProperty name; public SimpleStringProperty nameProperty(){ if(this.name==null){ this.name=new SimpleStringProperty();
[Code] .....
I have this:
lista = FXCollections.<Person>observableArrayList(); lista.addAll(new Person("uno"),new Person("due"),new Person("tre")); myListView.setItems(lista);
The problem is if I add /remove an item all is fine, the listView refreshes correctly:
Person p = new Person(tfld_textAdd.getText()); lista.add(0, p);
But if I change a value on an item into the observable list it doesn't:
lista.get(0).setName("new value");
I also have a table linked in the same way and the table workd correctly after I updated my Java version...
In my Java SWT application, I have few methods, that take longer time to complete. These methods has to be initiate and run as response to button click. There I want to implement progress bar to show the progress/status of long run method. Long run methods are Java Processes, in which it executes some command line functionality. (ex: run ls method in Linux).
Process p = Runtime.getRuntime.exec(command)
In progress bar status is set using setSelection method which takes int as argument. How to indicate the progress of process in progress bar, because I don't have int value to pass into setSelection method of progressbar.
I need to work with multiple threads in background in a JavaFX application. I have a screen with ten buttons and I need to 'bind' each thread with the button that started the thread. If the user pressed a button that had started a thread (in the main screen, MainController.java), I need to recover it to display the information that contains to display it on the controls of Details Screen ( a second screen, DetailController.java).
What Class do you recommend for this? Service?

It is possible to name the threads with any of these classes?
I have a TextArea and want to set a linear-gradient as background, which works fine:
.text-area { -fx-background-color: linear-gradient(to bottom, red 0%, blue 100%); }
The problem is that if the TextArea contains much text (and long scrollbars) it is nearly only red. Only if you scroll down to the bottom, it becomes blue.
I want the red-blue gradient always look the same, no matter how much text there is.
In HTML there's something like background-attachment: fixed, which would do the trick, but not so in JavaFX.
Can I achieve it nonetheless. Preferably without any ugly workarounds, like a transparent TextArea within another Pane where the wrapping Pane has the gradient.
I am developing a number of Data Structures in Bluej. Iv created a nice little arraylist program, and want to add a password generator to this program. People are already prestored within the arraylist, and contain attributes such as ID, name, password, etc. I can search a persons name within the list and then view their ID, password, and encrypted password. I want to add a field which will show password strength, bare in mind the password is already stored within the program and will not be entered via the user.
I understand that this could be done via a regular expression, or using some count method where certain goals/sets of characters increase the count which determine strength.
No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK); scene.setFill(Color.BLACK); scene.setFill() worked fine for previous versions of JavaFX.
I want to write simple game. Why if I press button UP and RIGHT it not move diogonally, may be it have special code. And how I need to write correctly border and gravity?
public class Main { public static void main(String args[]) { JFrame frame = new JFrame("Stickman"); Ground ground = new Ground(); frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE); frame.setSize(710, 480);
I tried a few things and I was unsuccessful at removing the border around my image button. It seemed simple enough when reading on StackOverflow but I'm still getting errors : s
ImageIcon cardIcon_1_1 = new ImageIcon("../images/empty.png"); JLabel cardImg_1_1 = new JLabel(cardIcon_1_1); cardImg_1_1.setBorder(BorderFactory.createEmptyBorder()); cardImg_1_1.setContentAreaFilled(false);
Errors:
Multiple markers at this line - Syntax error on token ";", @ expected - Syntax error on token ".", @ expected after this token

I'm using an applet it had to be in the initialize part of my program...
import javax.swing.*; import java.awt.*; public class PRJ04 extends JFrame { public static void main (String [] args) { PRJ04 frmApp = new PRJ04(); PanelChart pnlChart = new PanelChart();
[Code] .....
When I comment out the adding and setting of the pnlChart on my main driver, the pnlPopulationInputs shows up fine, and it runs ok. When I add the pnlChart I get errors like crazy and a white screen. My errors:
Exception in thread "AWT-EventQueue-0" java.lang.ArithmeticException: / by zero at PanelChart.drawChart(PanelChart.java:45) at PanelChart.paintComponent(PanelChart.java:24) at javax.swing.JComponent.paint(JComponent.java:1054)
[Code] ....
Once more with this one, I refer back to our in class example. Our programs are set up the same, yet he has no issues with the "/ by zero" exception.
What I am doing is loading a new image from resources in my project, so that I can get the size. Using this, I create a new BufferedImage with those dimensions. The following code is what I am using to take the original BufferedImage, and scale it.
Java Code:
public ImageIcon getBackImage(){ before = new BufferedImage((int)img.getWidth(null), (int)img.getHeight(null), BufferedImage.TYPE_INT_ARGB); int w = before.getWidth(); int h = before.getHeight(); try{ URL url = getClass().getResource("/Blue_Back.png"); before = ImageIO.read(url);
[Code] ......
The scaling seems to be working fine, but what I have noticed is a line of approximately 10 pixels at the top of the image. I took the original image and blew it up to ensure that I wasn't just enlarging undesired portions and this wasn't the case. I then tried to fetch a subImage of the BufferedImage, and that also left the padding at the top. Is there something I am missing that is placing this undesired padding at the top of my bufferedImages ?
