TableSelectionModel when new rows are added
Hi all, I am learning JavaFX API and can't understand how row indexes change when new rows are added to the table. Suppose, there are 3 rows in the table and row[2] is selected. When a new row is added at the beginning of the table then selected row index must change to 3. Could anyone explain how indexes are updated (the only methods I see are clearAndSelect but they are not good from viewpoint of performance)? By the way, could anyone say, why table was called TableView? I ask because there are TableColumn, TablePosition, TableCell but no Table. -- Best regards, Alex Sviridov
TableSelectionModel in javadoc and in sources
Hi all,
I am reading JavaFX API and came across the following problem about
TableSelectionModel
In javadoc (
https://openjfx.io/javadoc/11/javafx.controls/javafx/scene/control/TableSelectionModel.html
):
Module javafx.controls
Package javafx.scene.control
...
public abstract class TableSelectionModel extends MultipleSelectionModel
In javafx-11+14-sources:
package javafx.scene.control;
public abstract class TableSelectionModel extends
MultipleSelectionModelBase {
as we see TableSelectionModel extends different classes in source and javadoc.
Could anyone explain it?

Why does Skin have getNode method instead of getControl?
Hi all, In my previous message I asked why GridPane, HBox, BorderPane, VBox, StackPane don't have Skins. I was told that it is odd for them to have Skins ( Kevin Rushforth ) and only controls can have skins. I pointed, that every Node can have a Skin, but got no answer. Now I am reading Skin API and see there the following method: Node getNode() Gets the Node which represents this Skin. The Skinnable interface is implemented by the Control class, and therefore is implemented by all Control implementations. So, could anyone explain why in Skin we have `Node getNode()` but not `Control getControl()`. -- Alex Sviridov
Re[2]: Why don't GridPane, HBox, BorderPane, VBox, StackPane have Skins?
Hi Kevin, Let me explain the reasons of this question. We implement JavaFX (simplified) in TypeScript ( https://github.com/PavelKastornyy/script4j ) for web. For every JavaFX Node we have html element. For example, for Pane we have . So the question, where should we put all the logic about html elements of the Node? We thought that Skin is the best candidate, however, we found that not all nodes have Skins, for example GridPane doesn't. What would you advise? >Пятница, 26 апреля 2019, 17:46 +03:00 от Kevin Rushforth >: > >Those are layout containers, not UI controls.

Re[2]: Why don't GridPane, HBox, BorderPane, VBox, StackPane have Skins?
Hi Kevin, thank you for your answer. Skin, as I understand, is a visual representation. You write - `The ability to CSS-style a Pane should be sufficient to do what you want`. So, on one side is a Skin that is a visual representation, on the other hand we can change visual representation of Pane via CSS. However, it is odd for Panes to have Skins. There is no logic for me here. For me it is odd for Panes not to have Skins. Or I understand something wrong. >Пятница, 26 апреля 2019, 17:46 +03:00 от Kevin Rushforth >: > >Those are layout containers, not UI controls.

https://bugs.openjdk.java.net/browse/JDK-8092297
Dear JavaFX developers Seven years ago this issue https://bugs.openjdk.java.net/browse/JDK-8092297 was opened suggesting to add serialization of javafx properties. Seven years have passed and we still don't have it. I think you should not harry. We still can wait many years - 10, 20 etc. So that's ok. -- Alex Sviridov
TextArea doesn't scroll to bottom when texts becomes long and vertical scrollbar appears JDK-8189732
More then half a year ago I opened an issue https://bugs.openjdk.java.net/browse/JDK-8189732 that TextArea doesn't scroll to bottom when texts becomes long and vertical scrollbar appears. The issue is still not resolved and even fix version is not defined. Could anyone say the reason of this? It is very strange as such issues must be resolved very quickly. -- Alex Sviridov
Tab with rounded corners strange behaviour bug
Hello. I wrote to this mailing list about problem with rounded corners in tabs. They advised me to fire a bug at oracle official site. I did this way on 14 July 2015 (ONE MONTH AGO). And I got: We are evaluating this report and have assigned it a Review ID: JI-9022330. In the event this report is determined to be a defect or enhancement request, it will be referenced with a new Bug ID and will be listed on Bugs.java.com. For other related issues, please visit our Bug Database at http://bugs.java.com . On 20 July 2015 I got message from pardeep.k.sha...@oracle.com asking for full tests. I send him all test on 23 July 2015. And nothing from that time.On 28 July 2015 I sent him an email asking what is next but got no answer. What should I do now? How can I understand what with this bug? -- Alex Sviridov
Tab with rounded corners strange behaviour bug
I want to make tabs big with rounded corners. And this is my css file:
The final target to make tab headers bigger with rounded corners.
.tab:selected .focus-indicator {
-fx-border-radius:101000,101000;
-fx-border-insets:-7-7-9-8,-5-5-9-6;}
.tab-pane .tab-header-area .headers-region .tab:selected{
-fx-border-insets:10101010,10101010;}
.tab-pane .tab-header-area .headers-region .tab .tab-container .tab-label {
-fx-alignment: CENTER;
-fx-text-fill:-fx-text-base-color;
-fx-padding:01000;}
.tab-header-area .tab{
-fx-padding:410510;
-fx-border-radius:101000;
-fx-background-radius:101000;
}
However, some strange elements appear near corners and later appear. It can be
seen on the following images:
http://i.stack.imgur.com/kyICa.jpg
http://i.stack.imgur.com/0mnDq.jpg
I asked this question at stackoverflow
http://stackoverflow.com/questions/30690918/javafx-tab-rounded-corners/30692660#30692660
and one user said that this is Changing CSS Id at run-time on Tab does not
result in changing style bug
https://bugs.openjdk.java.net/browse/JDK-8090243
However, I am not sure that this is the bug I am talking about as css rules are
not set at runtime. This bug is important for me
that's why I want to be sure that THIS bug is my problem. Please say, if this
bug is my problem.

JavaFx8: One controller, two fxml,factory and @FXML problem - bug or limit
I've read the following from her e
https://docs.oracle.com/javase/8/javafx/fxml-tutorial/jfx2_x-features.htm
When a controller factory is provided to the FXMLLoader object, the loader
will delegate controller construction to the factory. An implementation might
return a null value to indicate that it does not or cannot create a controller
of the given type; in this case, the default controller construction mechanism
will be employed by the loader. Implementations might also recycle
controllers such that controller instances can be shared by multiple FXML
documents. However, developers must be aware of the implications of doing this:
primarily, that controller field injection should not be used in this case
because it will result in the controller fields containing values from only the
most recently loaded document.
As I understood it is the feature of javafx2. But what about javafx8? I did the
following test:
public class Test1Controller {
@FXML
public Button Test1Button;
@FXML
public void onTest1Button(){
System.out.println(TEST1 BUTTON IS PRESSED+Test1Button.getText());
}
}
public class Test2Controller extends Test1Controller{
@FXML
public Button Test2Button;
@FXML
private void onTest2Button(){
System.out.println(TEST2 BUTTON IS
PRESSED+Test2Button.getText()+Test1Button.getText());
}
}
test1.fxml
AnchorPane maxHeight=-Infinity fx:id=Test1Pane maxWidth=-Infinity
minHeight=-Infinity minWidth=-Infinity prefHeight=400.0 prefWidth=600.0
xmlns=http://javafx.com/javafx/8.0.45; xmlns:fx=http://javafx.com/fxml/1;
fx:controller=temp.Test1Controller
children
Button fx:id=Test1Button layoutX=300.0 layoutY=40.0
mnemonicParsing=false onAction=#onTest1Button text=Test1 /
/children
/AnchorPane
test2.fxml
the main code:
@Inject
private FXMLLoader fxmlLoader1;
@Inject
private FXMLLoader fxmlLoader2;
private Test2Controller testController=new Test2Controller();
@FXML
private void handleOkButtonAction(ActionEvent event) throws IOException {
CallbackClass?, Object controllerFactory = type - {
return testController ;
};
fxmlLoader1.setControllerFactory(controllerFactory);
fxmlLoader2.setControllerFactory(controllerFactory);
Parent parent2 = (Parent)fxmlLoader2.load(getFxmlStream(test2.fxml));
Parent parent1 = (Parent)fxmlLoader1.load(getFxmlStream(test1.fxml));
mainAnchorPane.getChildren().addAll(parent1,parent2);
As the result - I have two button on anchor pane. However, the Test1Button
doesn't have action handler so it is not clickable. What about Test2Button it
works ok and when I click it I get:
TEST2 BUTTON IS PRESSED Test2 Test1
It means that Test1Button was also injected. Besides I've noticed that if add
firstly to pane parent2 and then parent1 -
mainAnchorPane.getChildren().addAll(parent2,parent1); then
Test1Button works, but Test2Button is not clickable.
Why only one of handlers works? This is a bug in javafx8 or this is limitation?

comboBox.setValue and ActionEvent cycle
I have combobox with page numbers (1,2,3,etc). When user select the certain
page (by mouse or by keyboard(as combobox editable))
I want to show and total pages. That's why on combobox action I do:
@FXMLprivatevoid onPageComboBoxAction(ActionEvent event){
combobox.setValue(currentPage+/+totalPages)
} However this code ( combobox . setValue ) fires one more ActionEvent and code
cycles. I tried to use swithers like boolean ignoreActionEvent but it didn't
work as it seems event is handled in different thread.
How to solve such problem?
P.S. I understand that this problem is for user mailing list but I ask at
stackoverflow and get no answer.
