How can I set the default stylesheet for a user control that I have created? I want to make the control available for anyone to use and I want it to use a stylesheet by default without the user of the control having to do anything. I also want it to be possible for the user of the control to override the definitions set on the default stylesheet if he wants to.
View RepliesI have developed JavaFx application with playback option using JavaFx Media player and slider controls. I am updating slider value using javafx mediaplayer.currentTime().addListener() method by adding Change/Invalidate listener.
While playing MP4 video, slider values are not updating (Change/Invalidate listener not getting triggered while playing video) on Mac OS(version : 10.9.1). Below is the sample code snippet.
mediaPlayer.currentTimeProperty().addListener(new InvalidationListener() {
@Override
public void invalidated(javafx.beans.Observable o) {
updateSliderValue();
}
});
Is there a way you can control user input?
For example, is it possible to only allow the user to enter digits?
TabPane and Pagination controls. However, I would like to be able to create a vertical toolbar that controls page or tab display.
Is it possible to create a Pagination with no page control? Or is my guess of sizing the Pagination control so that the lower section is off of the displayed window, thus hiding the page info? Or, is it possible to create a TabPane with panels, but no tabs?
If I use an instance of Tooltip in my custom-control, it can not be imported to SceneBuilder any more. Using Tooltip in my custom-control skin works - is that the way it is supposed to be?
Background: I have a control (ValidatedTextField) which uses Tooltips to inform about unwanted characters. It works in SceneBuilder1.x.
SceneBuilder 2 does not "accept" this control unless I take out all Tooltips. I have verified this behavior with some other working controls.
I have found a workaround to use the Tooltip in the Skin.

Why I can't get an external style sheet work work when using JSP files? Putting a link in the doc head like I would for an HTML or PHP file does not work. The style sheet is in the exact same directory as the JSP files and I cannot get it to work. I think I have tried about everything that has been suggested on the web with no luck.
If I create an HTML doc in the same directory as the JSP files, and add the below line in the document head, it works fine. Doing the same thing with a JSP file does nothing.
<link rel="stylesheet" type="text/css" href="style.css">
I am using SAXTransformerFactory to output an XML file but can't figure out how to output the stylesheet setting, for example:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ectd:ectd SYSTEM "util/dtd/ich-ectd-3-2.dtd">
<?xml-stylesheet type="text/xsl" href="util/style/ectd-2-0.xsl"?>
I am using the following code to get the first two lines, I just can't see how to output the third line above.
SAXTransformerFactory mTransformerFactory = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
TransformerHandler handler = mTransformerFactory.newTransformerHandler();
Transformer mTransformer = handler.getTransformer();
mTransformer.setOutputProperty(OutputKeys.VERSION, "1.0");
mTransformer.setOutputProperty(OutputKeys.ENCODING, IBF_UtilXML.XML_ENCODING_UTF8);
mTransformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "util/dtd/ich-ectd-3-2.dtd");
I believe I found an example using a DOM approach but I would much prefer using SAX.
<?xml-stylesheet type="text/xsl" href="util/style/ectd-2-0.xsl"?>
I have a TableCell that will hold numbers in a tableview. All is working work nicely, but I want the following behavior:
- when the user begins to edit such a cell, if it doesn't enter a number, the cell will not call commitEdit, but rather display a red border and prevent the user from changing the focus to anything else until he either: enters a correct number or presses ESC.
I don't know how to keep the user in that editting cell if while he has an incorect number. Currently he can click other row/control and he will break the edditing state. I repeat, I don't want the user to be able to click on any row/control until he has a correct number.
Here is my cell implementation:
public class EditableIntegerCell extends TableCell<Person, Integer> {
private TextField textField;
@Override
public void startEdit() {
if (!isEmpty()) {
super.startEdit();
createTextField();
setText(null);

I'm trying to add a tooltip on a cell of a TableView in order to show some information to the user.
This is the code:
colonnaColore.setCellFactory(param -> {
TableCell<Appuntamento, Template> cell = new TableCell<Appuntamento, Template>() {
@Override
protected void updateItem(Template item, boolean empty) {
// calling super here is very important - don't
[Code] ....
In few words: there is a cell factory on the cell to show a colored box, then I added a tooltip to the cell. I need informations that are in the item added to the TableView that has type "Appuntamento". So I try to get my element with these code (that in others part of my code works); but here I get a Null Pointer Exception on cell.getTableView() and also on cell.getTableRow().
I'm probably using these methods in a way that was not expected.
how am i supposed to make line1B with "1f" and line2B with width of "10f"?

So I'm working on some networking code and I have the Server running as its own thread, then I have a PacketListener which is contained in the Server, that is running on its own thread too. As of right now, the PacketListener waits for packets via DatagramSocket.receive() and then adds them to a queue. The Server runs in a loop and it checks that queue for packets and then polls the most recent and process it before sleeping for 1 millisecond. Here is my question though, I'm considering changing the program to a more observer pattern structure in that when the PacketListener would receive a packet, rather than add it to the queue, it'd notify the server which would process it. However, wouldn't this cause additional time required within the PacketListener thread dedicated to processing the packets rather than listening for them?
View Replies View RelatedI have a multithreaded java program. I have a few worker threads which process data over a udp server. Then I have another thread for console input. The problem is when there is an error with one of the worker threads, and it prints to the console, my console thread loses "focus", that is, the while loop seems to no longer run. Here is the console thread:
Java Code:
public void run() {
Console c = System.console();
if (c == null) {
Logger.writeError("No console.");
System.exit(1);
}
while(true){
String login = c.readLine(">>>: ");
System.out.println("You entered: " + login);
}
} mh_sh_highlight_all('java');
When an exception is raised, it prints it to the console, and suddenly the program no longer shows the >>> prompt from above.
I'd like to ask is there way to control the RMI lookup timeout through programming or network configurations.
In a testing environment, I have purposely disconnect or plug out the cable between two testing servers to check the reliability.
It took very long time for the RMI API to throw out java.rmi.ConnectException which used Naming.lookup(givenURL).
I have tried to set system properties like sun.rmi.transport.tcp.handshakeTimeout, but it didn't take effect at all.

The LocalStudent class inherits the Student class. The IDE states an error of "no default constructor in Student class".I understand that if a LocalStudent object is created, the default constructor of its superclass (aka Student class) will be called implicitly.there is no LocalStudent object being created, so why is the default constructor of Student being called ?
The default constructor of LocalStudent is also overloaded by the created no-arg constructor containining subjects = null; . So there is no call to the superclass default constructor from the default constructor of LocalStudent.

private char year1;
public Student(String name, char year){
year1 = year;
}
