I've a tabview that contains a scrollPane, and a scrolPane contains nodes.
I added a button fit, i want when i click in this button the content of the scrollpane will be centered, I dont know how to do this
#FXML protected void onFitClicked(ActionEvent event)
{
//calling the method that centers the content of the scrollpane
fit();
}
that's what i've done until now .. :( i'll be happy for any help
public void fit()
{
m_scrollPane.setFitToWidth(true);
m_scrollPane.setFitToHeight(true);
}
Try
m_scrollPane.setHvalue(0.5);
m_scrollPane.setVvalue(0.5);

Im using a custom webview to display my text i made with htmleditor.
The custom webview adjusts the size of the webview so the text fits almost perfectly in it.
I make the webview "throw" its scrollEvent to the scrollpane with vbox in it it, so its not handled by the webview itself.
But still i see the text scroll up and down a bit inside the custom webview when i scroll over it. I read on some other post its the HTML itself that handles the scrolling. But i have no idea how to disable that.
webView.setOnScroll(new EventHandler<ScrollEvent>() {
#Override
public void handle(ScrollEvent scrollEvent) {
vBox.getOnScroll().handle(scrollEvent);
scrollEvent.consume();
}
});
Well for what I understood you don´t want the scrollbar to move your page
Set the scroll bar invisible
scrollBar.setVisible(false);
Disable the scrollbar, so on move the event won´t happen
scrollPane.addEventFilter(ScrollEvent.SCROLL,new EventHandler<ScrollEvent>() {
#Override
public void handle(ScrollEvent event) {
if (event.getDeltaX() != 0) {
event.consume();
}
}
});
Or you can use scroll panes, and set them to fit.
scrollPane.setFitToHeight(true);
scrollPane.setFitToWidth(true);
Hope any of these would help.
I need to reproduce this image in javafx see Interface
the way i approached this interface is as follows :
Created a BorderPane layout
BorderPane.TOP : set inside it a HBOX layout for the menu on top
BorderPane.Center : set inside it a Pane Layout which contains the the planets ( see image again )
this is end result i got click to see image
Clearly i am doing something wrong here , please clarify to me
this interface is supposed to be FULLSCREEN and responsive
i tried doing the following Controller Code:
public class HomeController implements Initializable
{
#FXML
private BorderPane borderPane;
public void initialize(URL location, ResourceBundle resources) {
// responsivity
Screen screen = Screen.getPrimary();
Rectangle2D bounds = screen.getVisualBounds();
Stage stage = Entry.getMainStage();
stage.setX(bounds.getMinX());
stage.setY(bounds.getMinY());
stage.setWidth(bounds.getWidth());
stage.setHeight(bounds.getHeight());
// this code gives an error
borderPane.setBottom(null);
borderPane.setLeft(null);
borderPane.setRight(null);
}
}
Firstly, sorry for my English. I hope, you unterstand it.
Last Month I started developing a little programm with FXML/ JavaFX.
I have two screens, and I'm switching between them. This is not the problem.
The problem is: On one Screen i have a listview, where i can choose an item. When i have chosen an item, i want to open a new tab on the other screen with the content of the item. Therefore, i have to click on a button.
When i have chosen an item, i can print out the selected item, but how do I open a new tab on the other screen. Both Screens a two different FXML and are activited from the controller. How can I add a Tab, although loading fxml?
public class Controller{
#FXML
private ListView<String> lv;
#FXML
private Button check;
#FXML
public void projectview (Event e3) throws Exception{
Stage stage = null;
Parent root = null;
if(e3.getSource()==check){
//Check is the declaration for the Button on the screen with the listview
String projectview= lv.getSelectionModel().getSelectedItem();
stage = (Stage) check.getScene().getWindow();
root = FXMLLoader.load(getClass().getResource("FXML1.fxml"));
//Here I want to add a tab in FXML1.fxml
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
}
}
If something is missing or not clear, please ask. I read other similar questions, but i don't know, what to do.
Thanks for help
I am relatively new to JavaFx and I need help in getting a Vbox to grow as nodes are added to it.
I've place a VBox in a ScrollPane. The VBox gets filled with TitledPanes as they come in. But once the TitledPanes fill the space allotted the Vbox, the TitledPanes begin to overlap. Ideally I would want to Vbox to resize itself and use the ScrollPane to navigate.
I have the Vbox Max Height set to USE_COMPUTED_SIZE. I've added a listener to the ScrollPane to listen to changes in size of the VBox but no luck. Any Suggestions?
scrollPane.vvalueProperty().addListener(new ChangeListener<Number>() {
public void changed(ObservableValue<? extends Number> ov,
Number old_val, Number new_val) {
vBox.setLayoutY(-new_val.doubleValue());
}
});
Is there any reason you are using a VBox rather than an Accordion?
With an Accordion you could use a ListChangeListener to check for changes in TitledPane number and then adjust the size of the Accordion if an item was added or removed:
accordion.getPanes().addListener(new ListChangeListener<Item>() {
public void onChanged(Change<tem> c) {
while (c.next()) {
if(c.wasAdded() || c.wasRemoved){
//resize Accordion in dependency of the vvalue of your scrollpane
}
}
});
For a VBox, the principle should still be valid:
vbox.getChildren().addListener(new ListChangeListener<Item>() {
public void onChanged(Change<tem> c) {
while (c.next()) {
if(c.wasAdded() || c.wasRemoved){
//rezise VBox in dependency of the vvalue of your scrollpane
}
}
});

I've been trying for days and days now to get a BorderPane region go over another region...
The problem is as follow: My app is set in a BorderPane root, With:
A header in its TOP region
A menu in its LEFT region
The content, depending on the page, in it's CENTER
And an optional panel on its RIGHT region
That right region is the problem. It should appear/disappear when clicking on a "notification button" that is in the TOP region. So far so good. The thing is that the app doesn't use the RIGHT region, so I'm trying to make the RIGHT region that contains an AnchorPane go over the CENTER region. The normal state of the app is without the RIGHT region and I don't want to resize the whole app when opening the noitifications. Tried several things, such as:
When clicking the notification button, send the CENTER part toBack() and set the RIGHT width to the 300 wanted pixels
Sending the RIGHT region toFront()
Sending the whole BorderPane toFront()
None of them work, as they all either not show, or resize the center part which I don't want. I'd like the RIGHT to float above the CENTER region when the notification menu is showing.... Is there any way to do that? Or maybe another idea to trigger a container that would show above the CENTER part? Of course, I go design the panel in every CENTER pane and make it visible or not, but my app is about 15 different center windows so it would be really bad in terms of modifications...
I think you should not be trying to make the borderpane do this for you or you will end up with behavior you do not want like the center NOT resizing when the application is resized while the panel is visible.
Remember that JavaFX is really 3D. How about you try to wrap the BorderPane inside of an AnchorPane, GridPane or ScrollPane (whichever makes sense) instead of trying to get the right insert to do your thing. e.g. add an ScrollPane (your Slider) to the containing AnchorPane and bring that to the front and anchor it's top, right and bottom.
This should give you a right-aligned ScrollPane on top of your borderpane.
Then of course if you want it to be fancy with an animated slide you can try this out : https://gist.github.com/jewelsea/1437374
or this:
http://blog.physalix.com/javafx2-borderpane-which-slides-in-and-out-on-command/
Here is a very rough example to show the idea:
public class JavaFXApplication2 extends Application {
ScrollPane slider;
AnchorPane root;
#Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("Slide in");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
root.getChildren().add(slider);
AnchorPane.setRightAnchor(slider, 0.);
AnchorPane.setTopAnchor(slider, 0.);
AnchorPane.setBottomAnchor(slider, 0.);
slider.toFront();
}
});
Label l = new Label();
l.setText("Test Label to Show inside content");
Label l2 = new Label();
l2.setText("Peek-a-Boo");
slider = new ScrollPane();
slider.setStyle("-fx-border-color: orangered;");
slider.setContent(l2);
root = new AnchorPane();
root.getChildren().add(btn);
root.getChildren().add(l);
AnchorPane.setRightAnchor(l, 0.);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
