how can I add the scroll abiltiy with VirtualizedScrollPane (explained in GenericStyledArea-#Adding Scrollbars to the Area) for InlineCssTextArea in JavaFx Scene Builder? Any suggestions?
I found a workaround.Editing the FXML-file by hand.
Like the RichtTextFX-Issue descriped:
<VirtualizedScrollPane
fx:id="sourceContainerTextScreenVirtualizedScrollPane"
layoutX="265.0"
layoutY="98.0">
<content>
<InlineCssTextArea
fx:id="theICA"
layoutX="0.0"
layoutY="0.0"
onKeyReleased="#handler"
onMouseReleased="handelrer2"
prefHeight="277.0"
prefWidth="674.0"
wrapText="true"/>
</content>
</VirtualizedScrollPane>
but add also a
#FXML private VirtualizedScrollPane<InlineCssTextArea> sourceContainerTextScreenVirtualizedScrollPane;
to your controller, if you want to controll it. Otherwise in my code it also works without controller declaration.
I hope this will help you till it is included into the Scene Builder.

I have a problem in JavaFX with FXML , i created an ImageView in FXML and gave it an id . how can i simply use the ImageView that i have created in FXML in the java class code ?
When defining the ImageView in your controller, you need to add the #FXML annotation before it.
An example in Java would be like so:
#FXML
private Canvas canvas;
And in the FXML file:
<center>
<Canvas fx:id="canvas" height="600" width="600" />
</center>
Just keep in mind that the name in Java must be the same as the id in the FXML file
Now I'm working with javafx and create small view with SplitPane.
In this SplitPane i have two TiteledPanes(named A and B). At first step of program working, only one TitledPane contains data (A). But after little user actions some information are put on B.
If i run my programm 10 times, at 7-8 times everything will be ok!
But in 2 times I have a problem with second titeledPane. It is consists with no data. This TitledPane loaded without any exceptions and all bindings are good, But it consists with no data. It is very strange, because in 80% of time everything is ok.
May be this is javafx bugs?
Any one have the same problem?
<fx:root type="MyView" dividerPositions="0.5" orientation="VERTICAL" style="-fx-background-color: darkgray">
<fx:define>
<TitledPane fx:id="A">
<AnhorPane>
<Label text="ALabel"/>
</AnhorPane>
</TitledPane>
<TitledPane fx:id="B"/>
<AnhorPane>
<Label text="BLabel"/>
</AnhorPane>
</TitledPane>
</fx:define>
</fx:root>
public class MyView extends SplitPane {
public MyView () {
try {
FXMLLoader loader = new FXMLLoader(getClass().getResource("MyView .fxml"));
loader.setController(this);
loader.setRoot(this);
loader.load();
} catch (IOException e) {
e.printStackTrace();
}
}
}
The problem was in loading fxml file proccess. There are a lot of data should be loaded after the load fxml file(in my model class relating to that fxml) and in future adding to existing fxml. Like binding properties and etc.
When I relocate above 80% of bindings in fxml file using ${} - the problem was solded.
So I am currently working with tabpane in JavaFx for the first time.
After it didn't work as expected I reduced the tabpanes content one bit at a time until it looked like this:
<ScrollPane prefWidth="Infinity" prefHeight="Infinity" fitToWidth="true" xmlns:fx="http://javafx.com/fxml"
fx:controller="de.Cos4U.ui.scene.control.CosplayView">
<VBox alignment="top_left" minWidth="200" prefHeight="200" spacing="5">
<TabPane prefHeight="Infinity" minHeight="Infinity">
<tabs>
<Tab text="Tab1">
<content>
<Label text="test"/>
</content>
</Tab>
<Tab text="Tab2">
<content>
<Label text="tests2"/>
</content>
</Tab>
</tabs>
</TabPane>
</VBox>
</ScrollPane>
After selecting "Tab2", the content area still shows the label "test". It is refreshed as soon as you scroll. It's a this simple tabpane, so why doesn't it refresh its content?
Edit: I am using 1.8u74 right now. I edited the fxml so now its as complete as needet but as reduced as possible.
The controller doesn't affect the tab pane in any way so. So far it handles simple user inputs. After removing anything i don't need for this example, it is reduced to 0.
I used to have the same problem. I don't have the exact reason why it doesn't update correctly, but if you want to force a refresh of the Layout, you can request it instead of using a workaround like changing the size.
requestLayout();
Suppose you want to set the content of a tab inside your controller.
class Panel extends TabPane {
private Tab tab;
public void setTabContent(Node container) {
tab.setContent(container);
getSelectionModel().select(tab);
requestLayout(); // to force refresh the layout
}
}
You then call this method from your controller.
(DUPLICATE & SOLVED - see answer below)
I'm doing my first steps in JavaFX and it seems quite hard to use the "SceneBuilder". I'm used to Android and the QtCreator. It looks to me that there is accessing the UI components much easier.
Something like findViewById(R.id.btnPushMe); <- Android Code
Actually I got an solution but it is quite uncomfortable to use. This looks as this:
FXMLLoader loader = new FXMLLoader(MainApp.class.getResource("../fmxl/main.fxml"));
AnchorPane pane = loader.load();
System.out.println("panechilds:" + pane.getChildren().size());
BorderPane border = (BorderPane) pane.getChildren().get(0);
System.out.println("borderchilds:" + border.getChildren().size());
the xml..
<AnchorPane fx:id="mAnchor" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="800.0"
xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="app.progui.MainController">
<children>
<BorderPane layoutX="-1.0" prefHeight="600.0" prefWidth="800.0">
<top>
...
Thanks in advance
Martin
Edit:
This is a duplicate question (but I will not delete it, because I took some time to find the answer - maybe because JavaFX wasn't asked as much as Android questions were..)
AnchorPane anchor = (AnchorPane) scene.lookup("#mAnchor");
found here: How to find an element with an ID in JavaFX?
You should use a controller class and access the UI elements there.
Basically you do:
<AnchorPane fx:id="mAnchor" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="800.0"
xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="app.progui.MainController">
<children>
<BorderPane fx:id="border" layoutX="-1.0" prefHeight="600.0" prefWidth="800.0">
<top>
...
And then you can access the fx:id-attributed elements in the controller with
package app.progui ;
// ...
public class MainController {
#FXML
private BorderPane border ;
public void initialize() {
border.setStyle("-fx-background-color: antiquewhite;");
// ...
}
// ...
}
The field names in the controller class must match the fx:id values in the FXML file.
It is possible to access the fx:id-attributed elements in the class that invoked the FXMLLoader, but if you need to do this it is usually a sign that your overall design is wrong. You can do:
FXMLLoader loader = new FXMLLoader(MainApp.class.getResource("../fmxl/main.fxml"));
AnchorPane pane = loader.load();
Map<String, Object> fxmlNamespace = loader.getNamespace();
BorderPane border = (BorderPane) fxmlNamespace.get("border");
assuming the fx:id defined in the FXML snipped above.
When you design for FXML, you typically design three things: the application logic, the GUI controller logic, and the FXML.
References to the UI controls you wish to access are injected by the FXML loader into your controller class during its loading and initialization so that you do not need to use a FindById() method.
A controller class looks similar to this:
class DCServRecEditor extends DialogController {
#FXML // ResourceBundle that was given to the FXMLLoader
private ResourceBundle resources;
#FXML // URL location of the FXML file that was given to the FXMLLoader
private URL location;
#FXML // fx:id="ancMatchSelector"
private AnchorPane ancMatchSelector; // Value injected by FXMLLoader
#FXML // fx:id="ancServEditor"
private AnchorPane ancServEditor; // Value injected by FXMLLoader
#FXML // fx:id="ancServRecEditor"
private AnchorPane ancServRecEditor; // Value injected by FXMLLoader
:
:
The FXML loading facility automatically injects references into instance fields that are annotated with the #FXML tag. To manipulate a UI control, just access its methods using the appropriate reference.
Separating the UI control logic from your application logic is highly desirable, and effects a "separation of concerns". When you get used to designing FXML UI's this way, you'll enjoy it.
<AnchorPane>
<TreeView fx:id="locationTreeView" focusTraversable="true" prefHeight="449.0" prefWidth="725.0" style="#tree
{
-fx-border-style:solid;
-fx-border-width:1px;
-fx-border-color:#ffffff;
}"/>
In the above fxml code I want to add one more <TreeView> but through the controller. How can I do this?
You will have to:
Give a fx:id to the AnchorPane:
<AnchorPane fx:id="theAnchorPane">
Add the corresponding field in the controller:
#FXML private AnchorPane theAnchorPane;
From the code that performs the addition you have to:
Create the new TreeView however you like:
TreeView newTreeView = ...;
Add it to the childen of the AnchorPane, possibly with some constraints:
theAnchorPane.getChildren().add(newTreeView);
AnchorPane.setTopAnchor(newTreeView, ...); // etc
