Hi palexdev,
I’m currently working on a JavaFX assignment for school and have been primarily using your library. Thank you for creating MaterialFX—it’s been incredibly helpful, especially the filtering feature in MFXTable.
I wanted to add a button to a column in the table, and I came across this (https://github.com/palexdev/MaterialFX/issues/25). Following the instructions, I implemented the following code:
```
public static void addRentalAgreementActionColumns(MFXTableView<RentalAgreement> table) {
MFXTableColumn<RentalAgreement> column = new MFXTableColumn<>("Action", true);
column.setRowCellFactory(rentalAgreement -> {
// Create a row cell
MFXTableRowCell<RentalAgreement, String> rowCell = new MFXTableRowCell<>(p -> "");
// Create a button
HBox buttonBox = new HBox();
MFXButton viewButton = new MFXButton(rentalAgreement.getId() + "");
viewButton.setOnMouseClicked(event -> {
ScreenManager.openAsModal(
ViewFactory.getRentalView(rentalAgreement),
(Stage) viewButton.getScene().getWindow(),
"Property Details"
);
});
buttonBox.getChildren().add(viewButton);
viewButton.setMaxWidth(50);
viewButton.setMinWidth(50);
buttonBox.setSpacing(5);
rowCell.setGraphic(buttonBox);
return rowCell;
});
table.getTableColumns().add(column);
}
```
The button is supposed to display the corresponding ID from rentalAgreement. However, when I scroll the table, the numbers displayed on the buttons always in range from 1 to 16 as video https://drive.google.com/file/d/1JaaRF7ci3KxydDn3afqlPYgy5NMeN9Lg/view?usp=sharing.
Could you check this?
Thank you so much!
> Please rep me pls @palexdev :'( I need your help ASAP because the deadline of this assignment is on 12/1/2025.
Ditch the old implementation and use the new table from [VirtualizedFX](https://github.com/palexdev/VirtualizedFX), you'll need Java 21 though
Examples are in the [tests](https://github.com/palexdev/VirtualizedFX/blob/main/src/test/java/interactive/table/TableTestUtils.java#L295)
> Thank you so much, but the new table doesn't have a filter feature, which is required in my assignment. :((
Ah, right
Can't you just add it yourself?
Like, wrap the table and a text field in a container (choose the layout you like) then use listen on the field's text to filter the table
I got a very good example for a recent project of mine
GUI:
Code:
[RefineList](https://github.com/palexdev/ArchitectFX/blob/f7428d5b03010dad40eccd1bbe3b48b5a42e6998/modules/frontend/src/main/java/io/github/palexdev/architectfx/frontend/utils/ui/RefineList.java): basically a wrapper for a source ObservableList, a FilteredList (what you need) and a SortedList. Makes it easy to filter and sort a source data set
[TextField](https://github.com/palexdev/ArchitectFX/blob/f7428d5b03010dad40eccd1bbe3b48b5a42e6998/modules/frontend/src/main/java/io/github/palexdev/architectfx/frontend/views/content/ProjectsView.java#L143): I'm using a custom [TextField](https://github.com/palexdev/ArchitectFX/blob/f7428d5b03010dad40eccd1bbe3b48b5a42e6998/modules/frontend/src/main/java/io/github/palexdev/architectfx/frontend/components/TextField.java) just to easily add icons to it
[Filter Action](https://github.com/palexdev/ArchitectFX/blob/f7428d5b03010dad40eccd1bbe3b48b5a42e6998/modules/frontend/src/main/java/io/github/palexdev/architectfx/frontend/views/content/ProjectsView.java#L274): from the previous link you can see I'm observing the field's text (`When.onInvalidated` is just a fancy way to add listeners to things from MFXCore), then I call this action but I don't filter immediately, I delay it with a PauseTransition of 200ms (optional, for a better UX)
Let me condense everything in a few lines here:
```java
// I'll use generics, replace with your model and cell classes
RefineList<T> list = ...;
VFXGrid<T, C> grid = new VFXGrid<>(
list.getView(), // returns the filterend and sorted list, that's the one we want to use in the grid/table
MyCell::new // Cell factory
);
TextField field = new TextField("Filter");
field.textProperty().addListener(i -> filter(list, field.getText()))
void filter(RefineList<T> list, String filter) {
if (filter == null || filter.isEmpty()) {
list.setPredicate(null);
return;
}
Predicate<T> yourPredicate = ...;
list.setPredicate(yourPredicate);
}
```
thank you very much for the detailed instructions.
But I am a freshman, I use JavaFX because the assignment requires me to use Javafx. I don't have much experience with Javafx or Java and the deadline is also coming soon. Maybe I have to find a different easier solution. By the way, thank you very much for the instructions and sorry for not being able to implement it.
as I understand, your solution supports only one kind of filter. I mean I want to be able to apply multiple filters for my table at one time which one is more complex.
