I have a FlowPane with many BorderPanes as windows. I would like to display something like water mark or label <empty> when the FlowPane is empty.
Is there any solution?
Have you tried something like this:
FlowPane flowPane = ... ;
StackPane container = new StackPane();
Label placeHolder = new Label("No content in flow pane");
placeHolder.visibleProperty().bind(Bindings.isEmpty(flowPane.getChildren()));
container.getChildren().addAll(flowPane, placeHolder);
Then, obviously, just add the container into your UI where you previously added the flow pane.

Putting a custom node as content on a TitledPane is fairly easy, but how can I set a node as the title of a TitledPane?
Can't really find anything on the subject, to a point where I start thinking it's not possible to do something other than
titledPane.setText("My title")
But that can't be, can it ?
Use the graphic property of the TitledPane:
HBox hbox = ...
TitledPane titledPane = new TitledPane();
titledPane.setGraphic(hbox);
Hi I'm trying to create a simple layout that looks like this using JavaFX.
I would like the user to be able to drag/resize the middle bar. I've tried to make this using a GridPane. But I can't figure out how to get the middle resized. Perhaps GridPane is not the way to go. Both panes will contain a lot of other program code later on. Thanks!
Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
stageRef.setMaxWidth(primaryScreenBounds.getWidth());
stageRef.setMaxHeight(primaryScreenBounds.getHeight());
GridPane gridPane = new GridPane();
gridPane.setGridLinesVisible(true);
gridPane.setPadding(new Insets(10));
Scene scene = new Scene(gridPane);
VBox vBoxMain = new VBox();
vBoxMain.setPrefWidth((primaryScreenBounds.getWidth()/5)*4);
vBoxMain.setPrefHeight(primaryScreenBounds.getHeight());
TextArea textArea = new TextArea();
textArea.setWrapText(true);
textArea.setPrefHeight(primaryScreenBounds.getHeight());
vBoxMain.getChildren().addAll(textArea);
vBoxMain.isResizable();
VBox vBoxSide = new VBox();
vBoxSide.setPrefWidth((primaryScreenBounds.getWidth()/5));
vBoxSide.setPrefHeight(primaryScreenBounds.getHeight());
vBoxSide.isResizable();
gridPane.add(vBoxSide, 1,1,1,1);
gridPane.add(vBoxMain, 2,1,4,1);
stageRef.setScene(scene);
stageRef.show();
You could use a SplitPane:
A control that has two or more sides, each separated by a divider,
which can be dragged by the user to give more space to one of the
sides, resulting in the other side shrinking by an equal amount.
Then you add two others containers to this pane allowing the user to change the position of the divider. You can also set minimum widths for each component within the pane or set the position of each divider within your code.
I have a flowpane in center and i applied a slider effect which gets invoke on a click of button on the right (so slider moves from right to left when expanded). I have followed JewelSea slider tutorial mentioned here Slider
Now i have two different flowpanes in two different nodes. Both the flowpane contains array of labels but the only difference is, One flowpane contains scrollbar and is contained in TitlePane while the other is without scrollbar and no titlepane.
So now if i click on slider the contents in the flowpane(without scrollbar & titlepane) gets automatically adjusted but its not the same case with the flowpane containing scrollbar.
Here is relevant code for flowpane with scrollbar-
public void loadCase() {
ScrollPane s = null;
if (!homeController.mainTabPane.getTabs().contains(testTab)) {
int app = 0;
if (appareaList.size() > 0) {
FlowPane fpTestmoduleContainer = new FlowPane();
FlowPane example = new FlowPane();
for (ApplicationAreas appttribute : appareaList) {
appTestTitledPane[app] = new TitledPane();
appTestTitledPane[app].setText(appttribute.getApplication_name());
appTestTitledPane[app].setPrefSize(Control.USE_COMPUTED_SIZE, Control.USE_COMPUTED_SIZE);
/*Module loop start*/
fpTestmoduleContainer.setHgap(10);
fpTestmoduleContainer.setVgap(10);
// fpTestmoduleContainer.setPrefSize(Control.USE_COMPUTED_SIZE, Control.USE_COMPUTED_SIZE);
List<TestModuleAttribute> testmoduleList = WSData.getTestingModuleList(appttribute.getApplication_id());
ArrayList<Label> listTestlbs = new ArrayList<Label>(testmoduleList.size());
System.out.println("testmoduleList.size()" + testmoduleList.size());
int i = 0;
for (TestModuleAttribute testmattribute : testmoduleList) {
listTestlbs.add(new Label());
listTestlbs.get(i).setText(testmattribute.getModule_name());
listTestlbs.get(i).setAlignment(Pos.CENTER);
listTestlbs.get(i).setTextAlignment(TextAlignment.CENTER);
listTestlbs.get(i).setWrapText(true);
listTestlbs.get(i).setPrefSize(Control.USE_COMPUTED_SIZE, Control.USE_COMPUTED_SIZE);
listTestlbs.get(i).setId(testmattribute.getFxnode_css());
Image imgInstalled = new Image(getClass().getResourceAsStream("/upgradeworkbench/View/Icons/ok.png"));
listTestlbs.get(i).setGraphic(new ImageView(imgInstalled));
listTestlbs.get(i).setContentDisplay(ContentDisplay.BOTTOM);
Tooltip testtp = new Tooltip();
testtp.setText("Total No. Of test Cases :" + testmattribute.getTest_case());
testtp.setWrapText(true);
listTestlbs.get(i).setTooltip(testtp);
addModuleMouseClickListener(listTestlbs.get(i), testmattribute.getModule_name(), testmattribute.getFxnode_css(), testmattribute.getTest_case());
i = i + 1;
}
s = new ScrollPane();
s.setContent(fpTestmoduleContainer);
fpTestmoduleContainer.setPrefWidth(1500);
fpTestmoduleContainer.getChildren().addAll(listTestlbs);
//appTestTitledPane[app].setContent(fpTestmoduleContainer[app]);
listTestlbs.clear();
app = app + 1;
}
appareaTestmoduleContainer.getPanes().addAll(appTestTitledPane);
appareaTestmoduleContainer.setExpandedPane(appTestTitledPane[0]);
testTab.setText("Test Cases Wizard");
testTab.setText("Testing Application Foot Print");
//mainTab.setClosable(true);
// testTab.getContent().setVisible(true);
HBox hb = new HBox();
testTab.setContent(s);
}
}
}
Image of slider working as expected - before sliding
After sliding (without scrollbar) the 4 modules get to the next row as space is occupied by the slider
After adding scrollpane and embedding flowpane inside it. Slider overlaps the flowpane contents as shown
I want to know why the scrollbar causing issue in auto adjustment of contents inside the flowpane and how can i fix it ?
Here the width of your scrollpane is fixed. And then so is the width of the flow pane.You need to change the size of your scrollpane so that its content gets reset.
Use the following code.
scroll[app].setFitToHeight(true);
scroll[app].setFitToWidth(true);
This code will set the size of scrollpane according to the view. The flowpane will also adjust accordingly then.
I'm trying to load a FXML into a FXML. The main FXML has a borderpane, and the second contains a VBox. I load both of these with the FXMLLoader. When I try to set the center of the boarderpane, the entire screen gets replaced with the second FXML. Here is the code
BorderPane riskAnalysis = new BorderPane((BorderPane) FXMLLoader.load(getClass().getResource("./proposaldevelopment/riskAnalysis.fxml")));
VBox center = new VBox((VBox) FXMLLoader.load(getClass().getResource("./proposaldevelopment/openRiskAssessmentVbox.fxml")));
riskAnalysis.setCenter(center);
root = riskAnalysis;
stage.getScene().setRoot(root);
Any ideas that could cause this? I also tried making a new label and putting that into the borderpane center with the same result.
Try as
BorderPane riskAnalysis = (BorderPane) FXMLLoader.load(getClass().getResource("./proposaldevelopment/riskAnalysis.fxml"));
VBox center = (VBox) FXMLLoader.load(getClass().getResource("./proposaldevelopment/openRiskAssessmentVbox.fxml"));
riskAnalysis.setCenter(center);
stage.getScene().setRoot(riskAnalysis);
I'm quite new to JavaFX and I have two methods - one returning a grid layout and the other one returning a HBox with a MenuBar, but fot the life of me I can't make it, so it's not overlapping (I want the grid to be a few pixels lower). I have this code in my start method:
final Group rootGroup = new Group();
final Scene scene = new Scene(rootGroup);
rootGroup.getChildren().add(addBar(stage.widthProperty()));
rootGroup.getChildren().add(addGridPane());
stage.setScene(scene);
stage.show();
How do I fix this?
You may use another Layout Manager as root. For example:
final VBox rootGroup = new Vbox();
Then all its children will be aligned vertically.
