问题 I have this css file which sets the default font size and type in JavaFX application: .root { -fx-font: 13px Tahoma; } scene.getStylesheets().add(getClass().getResource("/styles/Styles.css").toExternalForm()); I want to update the size and the font type from the Java code dynamically of the root component (all components). How I can do this? Note: This code updates the Font type and size of all components into the JavaFX application. 回答1: Please consider taking a look at the official JavaFX

问题 I have a task that can be long running, and it's blocking. I must wait for this task to complete to display results on the GUI.

问题 I am using JavaFX 8 and specifically the TextArea control. In that control I can enter free form text including "tab" characters. When I enter a tab, the data is spaced in units of 8 characters.

Data Here My puzzle is how to change the tab spacing/sizing for the visual so that instead of the tab size being 8 characters it will only be 4 characters. To

问题 I was wondering if in JavaFX, binding can be an alternative to action listener/events ? Can we handle all actions with binding instead of event handling ? 回答1: No, binding is not an alternative to event handlers. You could bind event properties to different event handlers, but then you would be using both technologies, not one or the other. Generally you use binding for synchronizing data values and event handlers for running code on some event. As an alternative to a bind call to set the

问题 I have the following code: public void setContent(Importer3D importer) { if (DEBUG) { System.out.println("Initialization of Mesh's arrays"); } coords = importer.getCoords(); texCoords = importer.getTexCoords(); faces = importer.getFaces(); if (DEBUG) { System.out.println("Applying Mesh's arrays"); } mesh = new TriangleMesh(); mesh.getPoints().setAll(coords); mesh.getTexCoords().setAll(texCoords); mesh.getFaces().setAll(faces); if (DEBUG) { System.out.println("Initialization of the material");

问题 I resize the image view according to the scene but image keep resizing even if the scene is bigger than image original size. I have set ImageView.maxWidth(originalImageWidth) but it did not work.

问题 I'm trying to use the text component of JavaFX to do some nice headline typography in my application. How ever the letters in the text are not spaced evenly. For example in the word " visiting ", the " iting " part seems disconnected from the first part. In the sample image I'm using Arial but this kind of bad spacing happens with every font I tried. This only happens when "gray" anti-aliasing is used ( -fx-font-smoothing-type: gray; ). One obvious solution would be to change -fx-font

问题 I have a JavaFX 3D scene with a bunch of boxes and spheres added at random locations. It seems like the depth order is all wrong and I'm not sure why. I have tried to use myNode.setDepthTest(DepthTest.ENABLE) but that doesn't seem to help. I've attached an application which should demonstrate the problem. Any idea what I might be doing wrong here? Any help much appreciated. import javafx.application.Application; import javafx.application.ConditionalFeature; import javafx.application.Platform;
