JavaFX 2.0 :: Unable To Bind Text Property Of Selected Cell Of TreeView To Label
Jun 5, 2014
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?
select 3 elements from the list: you'll see the log of the ChangeListener that tell you every time all items selected remove 1 element from previous selection: you will not receive the notification!!! remove the other two elements: only when the selection is empty you will see a new notification from changeListener...
I am developing a java swing application. In which i want to set a different text to a label in same program ( in single JFrame). I dont want to use another JFrame instead i want to use setText method of java and set different text to a label at different intervals of time according to my need.
I am using java 1.7 sdk and pupy linux as OS. Below i am giving source code.
What i am doing is in constructor of class i am setting an image to JFrame and setting text "Welcom...". And when user clicks on this JFrame a method is called which will clear the text "Welcome.." and sets new text to another label "Enter...." and from there another method is called and it clears label "Enter..." and sets a text "Plzz wait..". and yet there are more methods, i havnt provided here.
But what is happening is it shows welcome text and then directly Plzz wait..
Its not showing text Enter... because control is finished after last method gets executed.
My concern is i want to show all the setText (my messages) in a sequence. Without using another JFrame. There is no any user input other than user will click on first welcome page.
public class BackgroundFrame extends javax.swing.JFrame {
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.
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?
I need a code to get a text from a textField to a label but the label is on a different frame, i will give u an example of what i have so far. so this is the main:
package albaestate; public class AlbaEstate { public static void main(String[] args) { Frame1 first = new Frame1(); first.setVisible(true); }
/*[B]now i have the first frame where i input the information[/B]*/
package albaestate; public class Frame1 extends javax.swing.JFrame { public Frame1() { initComponents();
[Code] ....
What i need is to input the code so that in jLabel5 i get the text from jTextField1 in Frame1; in jLabel6 i need the text from jTextField2 also in Frame1; and in jLabel7 i want to display the calculation of what the jbutton1 in Frame1 is calculating.
I want perform some calculations whenever a specific cell block is focused in JTable, I've tried using focusListener on JTable but looks like my table isn't triggering the event. I don't know why, what to do?
I'm working on a spreadsheet like app using JTable and was wondering if I can make the first cell of the table be selected when the window opens. Is there a way to do so?
Is there an existing way to bind the content of a ListProperty? Consider the following:
private final ListProperty<Worker<?>> workers = new SimpleListProperty<>(FXCollections.observableArrayList()); public ListProperty<Worker<?>> workersProperty() {return workers;} public ObservableList<Worker<?>> getWorkers() {return workers.get();} public void setWorkers(ObservableList<Worker<?>> workers) {this.workers.set(workers);}
[Code]...
What I want to do is bind the content of the stateWatchedWorkers list to workers. If the entire workers list is replaced, I want stateWatchedWorkers to be updated to match the content of the new list. Put another way, I want the stateWatchedWorkers list to be mapped to the current list being held by the workers property.
This doesn't work ... I did not see anything in my TreeView...
Here is the MyCustomTreeCell class:
public class MyCustomTreeCell extends TreeCell<java.nio.file.Path> { private final ImageView icon; public MyCustomTreeCell() { super(); icon = new ImageView();
This is the code that I wrote but I have two problem with two buttons one of them ... I want to delete the selected text inside the text Area which represented as b[8] and the other button that I want to select parts of the texts which represented as 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?
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?
How do I keep an item (TreeItem) from being selected when performing a drag -n- drop? I don't want it to be selected because it will end up making the target disappear (selection of TreeItem changes target panel).
Related question: Is there a way to "veto" a tree selection change as well?
I have a case where I have a TreeView and I use it to select items from the tree. After I select each item I then clear the TreeView selection. Then, when I select outside of the window, the setFocused is called which in turn selects item 0 from the tree. I see in the TreeView.java the code,
private InvalidationListener focusedListener = observable -> { // RT-25679 - we select the first item in the control if there is no // current selection or focus on any other cell MultipleSelectionModel<TreeItem<T>> sm = getSelectionModel(); FocusModel<TreeItem<T>> fm = getFocusModel();
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt"; File textFile = new File(fileName); Scanner in = new Scanner (textFile); while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?
I have a Die class that extends Label. It has a SimpleIntegerProperty called faceValue. In another class I have an ObservableArrayList of Die called dice and a FilteredList of all the die in dice with a faceValue of 2. The Problem is that when I update the faceValue (ie. roll()) the filteredlist doesn't update with the Die that faceValue=2. I believe the reason is that the filteredlist updates when a ListChangeListener is fired. If i add, subtract elements from dice I don't have a problem but how do I make it so that updating the faceValue on the die counts as a ListChange, or is there even a way to do that.
In the SceneBuilder properties panels (part of Inspector pane) there are nice subheaders - separated by horizontal lines with a decent gradient in the background. I've tried to investigate the SceneBuilder source code at [URL] …, but I haven't found the proper file where this subheader is defined and styled.
I'd like to use similar subheaders in my app and why to reinvent the wheel...
I have a button whose text is being cutoff. How can I tell javafx that the button should be as big as the text in it and so no cutting off text happens?
