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 am developing an application where blind person can interact with computer i have completed the part where computer responds as per command given by user.The part where i am stuck is i want to give voice feedback as user moves the curser for example if mouse is on d drive then user should get feedback that its d drive....i want to do it for whole windows ...
I have now slowly moving on the learning Database Connectivity.Found a simple example on one site and tried to execute it, Creating a database, connecting to it and displaying the output.
I am getting trouble with recordset in displaying all the records in the badabase. It displays the very first record correctly but if I try to enclose it in while(rs.next()) loop, it generates an error message saying "Invalid operation at current cursor position".
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.");
My problem is simple. Just set busy cursor on a scene. The scenarios is like this: I have simple application with a button on it. When I click the button, I will:
1. Set mouse cursor to BUSY 2. Do some work 3. Set mouse cursor back to DEFAULT.
I search the web and found some sample codes to set cursor. But they don't satisfy my need. So I wrote a simple application:
public class MainFormApp extends Application { @Override public void start(Stage stage) throws Exception { stage.initStyle(StageStyle.DECORATED); Pane root = new Pane(); root.setPrefSize(500, 300); Button btn = new Button("Click me");
[Code] ....
When I run application and click the button, cursor does not change to BUSY. I also tried to use Platform.runLater() but no luck.
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 am developing a form with ComboBox as a subject (the user can choose one from the list , or type one) and TextArea where the user can write his notes (attached a picture). The user using a virtual keyboard (touch) to enter any characters.
I am using the append method to append the next Char to the TextInputControl class (both Combo and TextArea Inherit from it). When I try to deletePreviousChar() in the TextArea it works, but in ComboBox it fails
I put some System.out.println() to see what is the problem and it seems that with the ComboBox the class is loosing the Caret position after every action
Here is my code: (Look it also as a attached picture)
public void changed(ObservableValue<? extends String> observable, String oldVal, String newVal) { if (newVal != null) { if (lastNodeInFocus instanceof TextArea) { switch (newVal) {
[Code] ....
Here is the Debug results: CB = Combo TA = TextArea B=Before A=After , the numbers are the caret position (also attached as a picture )
CB - append B 0 CB - append A :1 CB - append B 0 CB - append A :2 CB - append B 0
I want to ask if there is an option to set the vertical position of the node handles of the TreeView-control.
I used a custom TreeCell factory with icons of sizes between 24 and 64 pixel and the location of the handle is regardless of the size of the icon on top of the cell. So if you got large icons the view did not look so nice.What I want is a property or something to center the handle in the cell depending on the size of the cell. Is there such an option?
How to catch the event when table view's column are re-positioned. Basically when the column is re-positioned from 1 position to 5 position , i want to do update the db.
I'm currently working on a project which requires to have text displayed along a curve. If found this entry a good starting point. It works fine for me on my develompment machine, however the customer on his machine noticed some issues.
The basic idea is to define a path for the text, explode the text into the separate characters and animate them along the path the fraction of the character of the whole lenght. So with a animation duration of 10 seconds and a label of ten characters, the first character would be animated along 1 second, the second 2, and so forth.
This is done by jumping to the designated time in the animation, start the animation and stop it immediately.
Now the problem as I see it, for stopping the animation a separate timer is used, so it can happen that at the time the animation is actually stopped, the animation moved further than the first frame. The effect is that the last characters of the text appear in front (wrapped around).
As I have no evidence to prove or disprove my theory, what do you think is this plausable? I can see a workaround for this issue by defining a path for each character and then let the animation run to the end. While I can set the duration of the animation to 1 ms which should not be visible to the human eye, I'm not able to make the characters invisible and turn the visiblity on when the animation finishes, they always become visible at the start.
Or create my own animation/transition for placing the characters.
I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description TextArea textArea = new TextArea(); Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT text.setText(usrNotes.getNote().trim());
Our users want us to build the following ontop of a TableView: When a key was typed, the row selection shall change to the first row showing a cell in a given column whose getText() starts with the typed letter. Such a functionality is known from lots of other software, like the Windows file explorer, where you can type a key to jump to the first file starting with that letter. It shouldn't be too complex to build, but due to the separation of "items" and "formatted cell text" it actually is... :-(
Using TableColumn.getCellData(S) we can access the item, but at that point, we don't want to repeat the formatting just for the sake of this functionality. We have set a cell factory providing this format, so the view looks great, but how can we access that formatted String programmatically to jump to the right row at a later time?
Switching from Swing to JFX 8, I am trying to find out how to do something I would normally do in a super-simple ListCellRenderer, i.e. customize the String displayed for an item. I tried this:
ComboBox<Integer> combo = new ComboBox<>(); combo.getItems().addAll(1, 2, 3); combo.setCellFactory(new Callback<ListView<Integer>, ListCell<Integer>>() { @Override public ListCell<Integer> call(ListView<Integer> param) {
[Code] .....
However, when I do this, the customized String is not used for the selected Item (rather the standard toString() value of the item). Apart from that it is no longer selectable using the mouse (I submitted a bug report for this at [URL] .... but that is not really the point of my question.
Anything else I have to do to make sure the selected item is also rendered using the custom cell or is there a different mechanism for this?
Is it possible to validate the input of a TextField that ist bound to a Property before both values are updated? Following is an example of my problem .....
In my model, there is a SimpleDoubleProperty discount. As you can see, there is some validation logic in the method setDiscount that might be used by other parts of the model.
public class Model { private DoubleProperty discount = new SimpleDoubleProperty(); public DoubleProperty DiscountProperty() { return discount;
[Code] ....
My Main class has a Textfield that is bound to the discount-property, a button to put the current value of the discount-property to console and a button to call the setDiscount-method ......
public class Main extends Application { @Override public void start(Stage primaryStage) { try { Model model = new Model(); BorderPane root = new BorderPane(); Scene scene = new Scene(root,100,100);
[Code] .....
By using the bidirectional Binding between the TextField and the discount-Property, the setter in the model is never called and therefore there is no validation of the input value. When calling the setter programatically with the second button, everything works as expected.
I experimented with neglecting the Binding and using ChangeListeners for both the TextField and the discount-Property but only produced infinte loops when both listeners triggered each other alternating.
I'm programming in school using Netbeans and we've just started with graphical programming (i.e JPanel, JClass, JFrame). This is my first assignment and the purpose of this program is that when you press the mouse you will fill 4 circles with diffrent colors. I've managed to draw 4 circles with diffrent colors but I want my cursor to change color simultaneously. Here's my code so far ....
//Java klass "Klick" public class Klick { //Medlemsvariabler. private int x = 0; private int y = 0; private int r = 1; public int antal = Rityta.antalKlick;
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 decided to change the mouse cursor based on the theme of the game. This is the code that I wrote for the declaration of the cursor:
ImageIcon imageIcon = new ImageIcon ("cursor / cursor.gif"); Image img = imageIcon.getImage (); Toolkit t = Toolkit.getDefaultToolkit (); Cursor cursor = t.createCustomCursor (img, new Point (0,0), "cur"); this.setCursor (cursor);
Having to click on different JButton in the menu of the game, a few screens later, I have to manage something in particular, such as determining the point of clicks that allows the action to take place?
In particular I would like to change the point of hotspots. The size of 136x163 is cursor.gif
Image - TinyPic - Servizio di hosting d'immagini, condivisione immagini & hosting di video gratuito
As you can see in the image I want to create the point of hotspots in the red dot of the image. How should I do to pass the correct coordinates in Point?
I've been creating a digital clock using Java, and have made the mouse cursor invisible after a set period of time (40-seconds) and had the thought to make it visible again if mouse was moved.
Here's the code that makes it invisible:
ActionListener mouseTimeout = new ActionListener() { public void actionPerformed(ActionEvent e) { setCursor(blankCursor); } }; /* Make mouse cursor disappear after 40 seconds */ Timer mTimeout = new Timer(40000, mouseTimeout); mTimeout.start();
And here is what I have so far for making it visible again:
MouseMotionListener mouse = new MouseMotionListener() { @Override public void mouseDragged(MouseEvent e) { } @Override public void mouseMoved(MouseEvent e) { } };
I have tried using "setCursor(DEFAULT_CURSOR)" but NetBeans says that it "cannot find symbol" .....
This is my code. It is running great until I enter in the final color and hit enter. I get an Array Index out of bounds error, which I show at the bottom. I have fiddled with it, by moving the all answers correct into an if..else statement, hoping it would fix it. Needless to say, it didn't work.
Also, I am trying to figure out how to make the cursor appear in each guess box. It does in the first one, but after I hit enter, I have to click in the box each time to get one.
