I have a column of my TableView that just shows row numbers, and I would like to style the cells in that column so that they appears just like a column header (so the same styling as the headers use). I presume there is some simple way to do this by tapping into the right style class, but I am not sure which one.
View RepliesI'm doing a bit of styling in TableView. The result is quite nice but I can't make the left top corner round. This is the actual result:
[URL] ....
And this is the css :
.table-view {
-fx-background-color: transparent;
}
/*HEADER */
.table-view .column-header{
[Code] .....
I would also like the top left corner was round.
I am facing an issue with the TableView in Java FX 8.
I am having a TableView created with data with scrollbars automatically added in when the Window is minimized.
I moved the horizontal scrollbar to right and then maximized the window to full.
After this the column headers remained no longer aligned with the content. When I click on any column header then the header aligns with the content.
The Issue is replicable also in case when a vertical scrollbar gets automatically added to a table view with preloaded data...
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.
View Replies View RelatedI'm using the tableview-component. The size of font of header is greater then that of cells. The problem is: the width of the column bases on the cell with the longest string and if the header-string is longer then the header gets truncated (it shows ellipsis) and I have to change the width of column manually. How could I solve this problem? The easiest way would be to compute the column-width on myself. I can't find any method in javafx, that would allow to compute the width of string in pixels. In Swing there is the FontMetrics class and Graphics class, so it is easy to get the width in pixels. Are there any pendants to this classes in JavaFX?

I am using the Javafx 8 Date Picker. Its works fine. I have defined a stylesheet for my application and in that style sheet i have a style for Button. I apply this style to the every scene. Now my question is: When I use the datepicker and I click on the calendar icon, the datepicker popup appears and the left and right arrows adjacent to month and year fields in the seems to pick the style of the button class from style sheet defined in my application., Is there a way to avert this and tell datepicker to use default styles and not the styles defined my application.
I tried removing the style at runtime from the scene, but of no use.
I have a VBox with 20 buttons and I have this style applied (menu.css) (only for VBox wrapper):
.button:focused {
-fx-background-color: #0768A9;
-fx-text-fill: #FFFFFF;
}
But when I pressed other button outside the VBox the style disappears, because the other button get the focus.
How I can do to keep the last button pressed with a custom style? (Only for buttons containing the VBox).

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.
I have an FXML table view. And I want to assign value from an tableview create on class to FXML tableview. But at the end is not displaying data.
Example:
@FXML private TableView fxmlTable;
private TableView insideClassTable;
public class SomeClass
{
public SomeClass(){
insideClassTable = new TableView();
//////////////////////////////////////////////////
Filling insideClassTable with data.
//////////////////////////////////////////////////
fxmlTable= insideClassTable;
}
// some other code and main
}
If I set value to fxmlTable, data are display correctly, but if assign value to insideClassTable first and then make fxmlTable=insideClassTable they are not display.
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 ?
I am trying to code a TableView with dynamic columns and I saw a lot of examples like this one: Creating columns dynamically. But any of those would work for my needs.
Its very simple:
I got a List of Customers, and each one has a List of Buys.
A Buy has a String "buyDetail" and a Date for the ship.
My TableView need to have the first column with the name of the Customer, and one column more for every day of existing ships. We don't know previously which days will be used. If the amount of money is superior of 100, for example, I need to be able of applying different styles.
Example:
Customer2015/01/022015/01/032015/01/09Morgan$400 (buyDetail)0$100Luis00$20Steven$1000Hulk0$5$32
I cant use the Properties because i dont know how many Buys will have each Customer.
My best try (only for the first column) was this, but I cant get the Buy updated if I edit the value in the cell: I didn't try to write the others columns code because I feel that im doing it really wrong.. This Shows the Customer´s names, but I cant handle if that data is edited.
table = new TableView<Customer>();
ObservableList<Customer> lista = FXCollections.observableList(registros);
table.setItems(lista);
TableColumn<Customer, Customer> customerNameColumn = new TableColumn<Customer, Customer>("");
[Code] ....
I created two CheckBox in 2 tableColumn and I want to listen theire change. I tried
col_orien.setOnEditCommit
But it doesn't work (col_orien is the name of the tablecolumn that contain the check box)
Here is my code :
col_orien.setOnEditCommit(new EventHandler<CellEditEvent<Information,Boolean>>() {
@Override
public void handle(CellEditEvent<Information, Boolean> event) {
System.out.println("Edit commit");
}
});
I have a huge data set 10000+ rows which I need to show in the tableview. It take a lot of time to render the UI and is slow.
View Replies View RelatedI want to use to tableview one beside the other so that they appear as a single table. but I do not find how to bound the height rows of the two tableview.
View Replies View RelatedI have multiselection working in my TableView but only via shift-click or using the keyboard but how do I enable the selection of several table rows via a mouse drag? It does not seem to work out of the box.
View Replies View RelatedTableView 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 would like to create list of entities which is populated by a search function with the data coming from our REST webservice. However I would like it to be multi-line, with the first line being details from the entity itself and the second line buttons for options that can be performed.
So as an example say my entity is People, the first line would contain columns for first name, last name, gender, DOB, etc. The second line would be buttons for "Edit Person", "Print Person details". With the standard TableView I can't see anyway to alternate between one row of data and another row of buttons.
I have a TableView and it is scrolled to have some rows visible. Lets call the top visible row T, and the bottom one B.
I now replace the items in the TableView with a whole new list of items (so new data to view), but I want to scroll back to either T or B.
It seems to me that I have to somehow keep track of the topmost visible row, or the bottom-most visible row, but I can't figure out how to do that.
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.
I am using the JavaFX dialogs. I have made a dialog as follows:
Alert d = new Alert(AlertType.CONFIRMATION);
d.setTitle(Resources.R(Resources.DELETE_DATA_SOURCE));
d.setHeaderText(...);
I want to make part of the header text bold -- I want a message like "Really delete X" where X is in bold.
Is there any way to do this with a dialog (other than rolling my own?).
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);
[Code] .....
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.
