问题 The problem is the following: I have a TableView with ComboBoxes where for every TableCell I can select a value from the comboboxes. The problem is, if I have a lot of rows and columns I have to click a lot to select the appropriate value in every comboBox. To select a value in a combobox I have to click four times to select the value. Once to select the cell, once to set the graphics the comboBox, again to open the popup for the combobox where I can select the value and finally to select the

问题 I wanted to change a (loaded) text font dinamically for my javafx application, so I did this code: Font font = Font.loadFont(Fonts.class.getClassLoader().getResource("path/font.woff").toExternalForm(), 25); Font bold = Font.font(font.getFamily(), FontWeight.BOLD, font.getSize()); Font italic = Font.font(font.getFamily(), FontPosture.ITALIC, font.getSize()); Font boldItalic = Font.font(font.getFamily(), FontWeight.BOLD, FontPosture.ITALIC, font.getSize()); but when I try to change the text

问题 JavaFX is not working for me using IntelliJ. While it does compile, I get an Exception when trying to launch. I've found similar issues here, none of which seemed to hold an answer to my problem. The Exception I get is the following: Exception in thread "main" java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java

问题 When I try to perform unit tests on components which contain JavaFX controls I get a java.lang.IllegalStateException: Toolkit not initialized . How can components be unit tested which operate with JavaFX controls? 回答1: Add the following dependency to your project <dependency> <groupId>de.saxsys</groupId> <artifactId>jfx-testrunner</artifactId> <version>1.2</version> </dependency> and the following annotation to your test classes @RunWith(JfxRunner.class) 回答2: Just declare and initialize a JFX

问题 Is there a way to make editing a relatively large text file (ex. 10-25 MB) in a TextArea reasonably fast? Or maybe there are features that can be disabled to make it faster? Is there an alternative component? (I know about RichTextFX, but I imagine it'd be slower since it does more, and I only need a basic editor.) I'd rather not break the source text up into smaller parts and only load a portion of the text, since that would break text selection+copy (ie. "select all" would only be selecting

问题 I am using Javafx v8.0.25-b18. The problem I occur is that the size of the dynamic combox's dropdown list doesn't change, so if I had initially two items in the dropdown, then the dropdown size will be good for two items, but if I now populate the dynamic combox with three items then I get a small scrollbar inside!?, If I remove an item - I will have a blank space in the combox !? I want to "reset" the dropdown size each time I put values into it, so it will be the right size each time it

问题 I want to create a SnapShot/Screenshot/Image from a WebView in JavaFX(8). This WebView does not need to be visible (in my case). My question: Is it possible (in any way), to create a Screenshot/Image from a WebView, when the WebView is not visible (or not added to any visible container) ? See my example code, when WebView (or it's parent ScrollPane) is visible=false , the Screenshot won't work (respectively is emtpy/blank ). Example code: package test; import javafx.animation.KeyFrame; import
