JavaFX 2.0 :: How To Add Text Change Listener To HTMLEditor
Mar 26, 2015
I am using javafx 2 in my project,After user change the text in HTMLEditor,i will save the context to database,if text wasn't changed,then i do nothing .so i want to know if the user have changed the text.
I only saw how to add text changed listener to HTML web viewer. So how to add text changed listener to htmleditor?
I'm using HTMLEditor in my simple test application and I'm showing html text generated. I noticed that accented letters (à,è,ì, ect) are not escaped (àect ect). Looking at the source code I arrived to the class
com.sun.webkit.WebPage
In which the method I thinked is used is this:
public String getHtml(long frameID) { lockPage(); try { log.log(Level.FINE, "getHtml"); if (isDisposed) { log.log(Level.FINE, "getHtml() request for a disposed web page.");
I want to do something when the treeitem collapsed or expanded,but both clicked the tree item icon and double clicked tree item can collapsed or expanded the tree item.so how to listen collapse and expand event?
I can't recolate and align the button, the circle or the line where i want it to on the canvas. I want to be able to move the line where i want it, now it seems like all objects are stuck in the middle of the scene or canvas.
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)); } } };
We have developed a theme called default.css that is extending of the default caspian.css. What we want to do is offer users the ability to override values from default.css to change colors etc. How can that be done?
I have a table column and I want to change the columns header justification from center justified to left justified. How do I do this, either via code or via CSS.
is possibile to change the color of the sorting arrow that appears in the columns of the Table View by css? My attempts have failed and I have not found any documentation, nor is there any reference in the Modena css.
I've been working on a small text-based RPG for fun. This particular part is supposed to allow the user to change their name. Now, the problem is that when they reach the option to change their name, the above code seems to skip the line:
name = scan.nextLine();
It will erase whatever the player previously entered for their name, as well. So it will print out:
Okay, let's change your name. What did you say it was? Alright, so you'll go by . Is that correct? [now allows input for verifyNameChange]
The above code works fine on it's own, but somehow messes up when put into the full program. I don't want to post the whole program, because it's fairly large. But the String name is set and functions fine before this bit of code.
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 am trying to write an application where if you click and hold down on 1 button and move the mouse to another button and release the text on the 2 buttons should be switched around.I have a print line so I can se the text are supposed to get switched around but it is just not happening in the GUI.
I attached all my code in case the flaw was to find somewhere else in the code, but the functionality I am working on is the lines 76 to 121.
Here's my coding so far...I want to be able to change what the JLabel says when clicking on one of the buttons for example : when clicking on UP i want it to say "Going Up!"...how do i do this?
import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JButton; import javax.swing.JLabel; public class BorderLayoutJFrame extends JFrame {
Ok, so I am trying to learn about JFrames and JPanels. I have figured out buttons, layouts, etc. What im having trouble with is accessing the label object from the ButtonHandler class since it is static and I need my JLabel to be non-static so that it can change. Basically, I want JLabel to change to a pre-determined text string once a button is pressed. Here's what I have so far
I can't seem to understand how to change certain line of text, inputted from a file. For this I really don't know where to begin. I have got the input from the file. But I want to change like very other line in the file. Can't seem to understand how this could be done. Is there away to access specific lines from the file and edit them? So far, i have this:
import java.util.*; import java.io.*; public class ChangeEveryOtherLine { public static void main(String[] args){ //Constructing file object representing input file File inputFile = new File("input.txt");
i just started java and I'm trying to change the JLabel text by clicking on the JButton however it isn't working,
import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JButton; import javax.swing.JLabel; public class BorderLayoutJFrame extends JFrame { public static final int WIDTH = 400; public static final int HEIGHT = 400;
I'd like to change the text on the two buttons which I have in my Dialog Box, how should I do this?
Also, when I click the X Button in the top right of the Dialog Box, nothing happens, and the program only stops when I end it in jGrasp. How do I make this button close the program when clicked on?
import javax.swing.*; import java.util.Random; public class SwingInputExample { public static void main(String args[]) {
