JavaFX WebView Context Menu

阅读更多关于 JavaFX WebView Context Menu

问题 I am trying to implement a simple browser using the JavaFX WebView/WebEngine inside of an SWT application using the FXCanvas. For some reason, the inbuilt context menu (with things like Refresh Copy/Paste etc.) does not seem to be working. If I create my own JavaFX context menu then it works, but I can't find a way to determine what HTML element is under the mouse at a given point (i.e. to have different menu items for links vs. images) A simple example that shows this behavior: import org

When I looked at thread stack after hitting a breakpoint there, it looks like code was getting executed in JavaFX Application Thread

JavaFX edit WebView in FXML document

阅读更多关于 JavaFX edit WebView in FXML document

问题 My goal is to be able to put html content into a WebView object in the fxml document using the controller class. My FXML document has other objects in it like buttons and images, I want the WebView just to be part of the GUI. I can put content inside a TextArea in the FXML document using the controller class.

问题 I'm developing a data mining application in JavaFX which relies on the WebView (and thus also the WebEngine). The mining happens in 2 steps: first the user uses the UI to navigate to a website in the WebView to configure where interesting data can be searched. Second, using a background task that periodically runs, a WebEngine loads the same document and tries to extract the data from the loaded document. This works perfectly for most cases but recently I've ran into some trouble with pages
