How to define Cell in the table by table event?
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.
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.
View Replies View RelatedI want to set different colors for different columns in the table. I use JLabel for setting the background color. Here is the code
private Color colorGreen= new Color( 44, 222, 74);

I would like to create a JTable.
Each cell contains an array of 4 objects:
[0] ImageIcon
[1] ImageIcon
[2] Number
[3] Boolean
1) Once JTable is displayed, each cell display only [0] .
2) Later, based on user mouse click on cell, cell should display [1]
How can I use an array with 4 values in Table Cell?
I would like to get a checkbox within a table to fire an event when it's clicked rather. I gave tried putting in a TableModelListener but the the event only seems to trigger when I click on another column (as if the table is waiting to see if I will change my mind) before moving on.
I have also looked at the setValue of the TableModel itself.
Do I need to put an ActionListener on each checkbox or have I missed something ?

I have a little problem in my Java FX application. in a tableview, I add records whatever... And i have a button that delete the selected record in the tableview, This button delete too the related record in a database.
When I select a row in this table , I store the ID of that record in a global variable to have it available . Thus, when I click on the delete button, delete the record from the database based on the ID that I stored in the global variable.
The problem is that tableview has a curious property. If I select the last row and I click on the delete button ( removing the last record of the tableview ) , the next higher row is automatically selected ; and causes the ID value stored change .
The row is deleted in the tableview is correct but apparently , when it comes to the method deletes the record from the database, the global variable ID is already updated and delete another record.
I would like to disable that property of the table so that the row can be selected only by the mouse ... or some other solution .

public void initialize(URL url, ResourceBundle rb){
table.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);

I am trying to load a CSS file from a mySql DB table (each row represent a customer that use the application, and each one can set his own CSS file).
How can I convert the Stream / String that I loaded from the Clob column to something that I can use here XXXX
scene().getStylesheets().add( XXXX );
I found alot of examples, but they all talking about files from filesystem, or URLs. My CSS file is in the application memory. I want to prevent the option to write my string as a new file and then read it again. I have no problem with loading the CSS file from database, this part is O.K.
Release 8u40 introduces the TextFormatter concept in the text input field area. It is currently a new property of the TextInputControl class. This is definitely a more elegant way to deal with validation than overriding "replaceText(...)".
Shouldn't this property also be available in list, table and tree cells? Are there plans to do this (before we make our own implementation) ?
I would like to defined a TableView with a column containing a CheckBox.
This can be done with an instruction like this : myColum.setCellFactory(CheckBoxTableCell.forTableColumn(myColumn);
The problem is how to specify that the displayed CheckBox is an indeterminate one ?
Here is another cell colouring question with a different take. Say you have a TableView with three columns - Category, In and Out. You add an empty row and then you start editing the Category column. When you have added a category you would like to see a change in the colour of the other two column cells in the same row depending on the category value.
Say if the category is 'income' then the 'In' cell will become green and the 'Out' cell becomes red. The important point here is that these cells and the underlying domain object does not have any values associated with these columns yet. The cells are empty and colour change is to show the user where the value should be put for the given category (into the green cell ).
Therefore after the category value is committed a 'message' needs to be propagated from the category column to the current row (or the whole table) to repaint itself. I have tried calling the following methods from the Category column's 'commit()' method but neither of them triggers a repaint:
- getTableRow().requestLayout();
- getTableRow().updateTableView(getTableView())
- getTableRow().updateIndex(getTableView().selectionModelProperty().get().selectedIndexProperty().get());
Once the re-paint is triggered then both In and Out column table cells can take the current category value from the underlying domain object (say MyRecord) like this
MyRecord record = getTableView().getItems().get(getTableRow().getIndex());
String category = row.getCategory();
and call the setStyle(".....") on the cell to change the colour.
TableView selection model allows selecting single cells in the table but the default styling highlights the whole row regardless of the actual column selected in the row.
I am just wondering what options are there to change this behaviour so that the actual cell (row/column) get highlighted rather then the whole row.
Something like the $18,000 cell in the "Figure 1 Table overview" in [URL] ....
I am trying to style the TableCell that has focus in a TableView to simulate how Excel does it. Excel uses a white background with a 3px black border which seems to be centered on the nominal cell edges. That is (and this is issue I am having), the border extends outside of the nominal cell boundaries.
My first naive attempt was to to override the CSS for .table-cell as follows:
.table-cell:selected:focused
{
-fx-background-color: white;
-fx-text-fill: -fx-text-base-color;
[Code]....
Doing this fixed problem (1) from the first attempt since this approach tweaks the background colors without affecting overall TableCell size. However, it still puts the black border completely inside the cell. My attempt to set -fx-background-position to a negative value in an attempt to offset the background seems to be ignored.
Having done this before using a Flex AdvancedDataGrid, my solution was to add a layer on top of the grid which renders the focus rectangle. I wonder if I would have to do a similar thing here.
I have a list of Row objects and want to listen to changes in the name property of a Row object.

this.name.set(name);

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.
How can I make variable from table value? Example:
Java Code:
String table [] = {"vara","varb"};
for(int i = 0; i < table.length; i++)
{
int table[i] = i;
} mh_sh_highlight_all('java');
And vara = 0, varb = 1 here.
Is this even possible?
I am trying to make a square root table from 0 to 20, but for some reason, mine is only going to 10.
public static void main(String[] args) {
System.out.println("Number SquareRoot");
double table[]={0,2,4,6,8,10,12,14,16,18,20};
for(int counter=0;counter<table.length;counter+=2) {
System.out.println(counter + " " + Math.sqrt(counter));
}
}
creating a table, and this is the code that I go down so far:
import java.util.Scanner;
public class program1 {
public static void main(String[] args)
{
String heading1 = "Quiz 1";
String heading2 = "Quiz 2";
String heading3 = "Test 1";

I have a JavaFX 8 TableView with multiple columns. The CellValueFactories for the columns are set as:
xxxColumn.setCellValueFactory(new ItemCountFactory(itemName));
where itemName is a String identifying a different item for each column.
ItemCountFactory returns a StringBinding as the cell value, as follows:
public ObservableValue<String> call(CellDataFeatures<Category, String> rowData) {
return new ItemCountBinding(rowData.getValue(), itemName);
}
where
class ItemCountBinding extends StringBinding {
...
protected String computeValue() {
String cellValue = ...;
return cellValue;
}
}
The StringBinding depends on properties of the Category instance for the table row. The correct data is displayed okay, but I have noticed that every time one of the Category properties changes (i.e., every time a cell value changes), ItemCountFactory is called again to create a new StringBinding. I would have expected the Factory to be invoked just once for each cell during initialization, and then the table column would monitor the returned Observable object. Instead it seems to be creating a new Observable object every time the cell value changes. Is this normal, or am I doing something wrong? Same behavior on Java 8u20 and 8u40. If it is not the expected behavior, I will write an example test program; I do not want to post the current full source code.
The table items are set just once, with:
countTable.setItems(categoryList);
where categoryList is of type ObservableList<Category>. The list itself is not modified after being associated with the table; i.e., no rows are added or deleted or replaced.
I am building an application that shows tables with large amounts of data containing columns that should display a thumbnail. However, this thumbnail is supposed to be loaded in the background lazily, when a row becomes visible because it is computationally too expensive to to this when the model data is loaded and typically not necessary to retrieve the thumbnail for all data that is in the table.
I have done the exact same thing in the past in a Swing application by doing this:
Whenever the model has changed or the vertical scrollbar has moved:
- Render a placeholder image in the custom cell renderer for this JTable if no image is available in the model object representing the corresponding row
- Compute the visible rows by using getVisibleRect and rowAtPoint methods in JTable
- Start a background thread that retrieves the image for the given rows and sets the resulting BufferedImage in a custom Model Object that was used in the TableModel (if not already there because of an earlier run)
- Fire a corresponding model change event in the EDT whenever an image has been retrieved in the background thread so the row is rendered again
Btw. the field in the model class holding the BufferedImage was a weak reference in this case so the memory can be reclaimed as needed by the application.
What is the best way to achieve this behaviour using a JFX TableView? I have so far failed to find anything in the API to retrieve the visible items/rows. Is there a completely different approach available/required that uses the Cell API? I fail to see it so far.
We are doing a Timeline project, So this is what i want to do:
Pressing a "New Event" button opens the New event window where you are supposed to write input in three fields, name, date, and information. There is also a button "Create" that when i press that button, i want to take all the input from the fields and save/send it to our database, and go back to the timeline GUI. With this, i want a new event object to be created(in this case i have done several shapes in a group) so basically a new group i want to be added. All the information is suppose to be taken from the database right after i create it.
I'm pretty stuck on how i should solve this, for the moment have a group called event that i add on the canvas. First thing that pops up in my head is a void method that draws the event, or maybe a temporary array.. P

import controllers.CreateEventController;

I have a TreeView insight TabPane
treeView.setOnMouseClicked(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent mouseEvent) {
if (mouseEvent.getClickCount() == 2 && mouseEvent.getButton() == MouseButton.PRIMARY) {
// Some action
}
}
});
For some reason when I click on a tab body I can also perform the listener action. How I can add additional statement to perform the action only if I select node?
This simple program should build a new table with random values and on the getValue method (perhaps called from othe TestClass) return back content of particular cell. why my getValue method doesn't work. Nay! It returns error while compilation.

public int getValue(int a){
return tabl[a];
} //getValue method end

just want the codes for how to add the listed quantity?
Can be :

I have two separate applications who will access the same table in a database and the two application will update the table.
How can I make sure the integrity of accessing this table? Is it in the code or in the database level?
