JavaFX 2.0 :: How To Disable Loading Of Images By WebEngine
Jun 2, 2014
I've searched everywhere but found no way to disable loading of images by Java WebEngineHow to do it?
Research done:
I found some ideas, such as using URL.setURLStreamHandlerFactory() to use my own URLStreamHandler, and having that analyze the URL to only return URLConnections for URL's that don't end in .jpg .png etc.
But that has many problems: Sometimes the image url doesn't end in .jpg, if it's a dynamic image, such as a captcha. So how can I disable automatic image loading from WebEngine?
I get this error when I load a HTML page with WebEngine. The HTML is getting generated by an own (Java-)ServerSocket. How can I figure out where the problem is? I can load the HTML file successfully when loading the(same) generated HTML file from the local filesystem. Maybe the http headers causing these problems ? On the other hand I can load the page without problems in Firefox. How to get more information ?
I usually code in PHP, C++ and ActionScript.I'm trying to follow an example of how to add images to a full screen application. What he does is that he adds a JPG background image, and then 4 PNG images. I tried to do it like I always do, by writing the code by myself looking at the book. It didn't work. I searched for errors in the code, changed some things, tried different things, but it didn't work. Then I tried to use his own code, that I downloaded from his website. That didn't work either.. I tried to find another way to add an image, and I can't seem to figure out a way to implement images in any other way into this class that's written in this book.. My Java programming level isn't just high enough.
Here's the code for the file where the images load, downloaded from the authors website (I've modified the brackets and some spaces so that it becomes easier to read):
Java Code:
import java.awt.*; import javax.swing.ImageIcon; import javax.swing.JFrame; public class ImageTest extends JFrame { public static void main(String[] args) { DisplayMode displayMode;
Like the title says: I'm loading a local HTML file in a WebView which contains Javascript. The script works without any problem when the page is first loaded, but when I reload it or load another local page, Javascript simply stops working silently for no apparent reason and with no error or exception of any kind.
I have a WebView which displays a site. At a specific page I want to fill in some values into <input> elements. So i use such an event handler (browser is of WebView class)
browser.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>(){ public void handle(MouseEvent e) { Document doc = webEngine.getDocument(); if (doc == null) { System.out.println("Doc is null");
[Code] ....
The handler sets the "value" but view doesn't reflect that, field is empty.
I'm trying to open URL's that the WebView considers Popups (it triggers the PopupHandler installed through onCreatePopupHandler) in an external In the PopupHandler I return a Webengine on which I installed a StateChanged listene and when the State changes to SCHEDULED I run some code top get the location of the WebEngine and open that URL in an external browser and then cancel the loading of the URL by canceling the LoadWorker using the LoadWorker.cancel() method wrapped in a Platform.runLater(..) call (in order to not crash the JVM).
However, then the PopupHandler is invoked because a window.open(url) was called in JavaScript in the main WebEngine, something odd happens: while the canceling of the loadworker was successful (it returns true and the LoadWorker goes to state CANCELLED), all of a sudden the state goes back to scheduled and my StateListener is called again with a newState of SCHEDULED, to if I don't work around it, the URL is opened again in the external browser. I can work around this by keeping track if the URL was already opened in the external browser once, but from what I can tell, this is just a bug.
I'm working on loading SVG images on Jpanel using "Apache(tm) Batik SVG Toolkit" , but after the image get loaded it has "white background" and "not transparent" one like PNG images.
I checked "fill" of rect attribute on the xml file of the svg image and it was correctly set to none, I also Tested the image on html document and it was trasparent, but in my java app it has white background.
The Question is there any way to load SVG images with transparent background on Jpanel ?
Is there a way to achieve this? Using setDisable(true) deactivates the entire control. I want the drop down menu items to still be accessible, but the action area visibly inactive.
I am trying to figure out the best way to load localized versions of FXML content. I know that I can localize strings, images etc. by specifying a ResourceBundle when loading the FXML using FXMLLoader with a ResourceBundle. But what about if you need to tweak the FXML for different locales (eg, adding more real estate for certain elements, different fonts, etc). Is there any way to create localized versions of FXML content? The only thing I can come up with is a naming convention like MyForm.fxml, MyForm_de_DE.fxml, ... and trying to load them based on the locale, but I'd have to come up with my own fallback for specific locales that aren't found.
When I assign a classpath-relative URL to an ImageView's 'Image' property, SceneBuilder is unable to display the Image in the Preview. It shows the text "Image not found" instead as a placeholder, which makes sense. What I'd like to do is add a classpath entry to SceneBuilder such that it is able to locate and display the Images. Any way to accomplish this (or similar)?

i think the problem is to do with my images not being recognised. I put them in my source in User>...>workspace>src which is correct as far as i know. From what i know the images should show up if i look at my src file in eclipse but they dont. I tried changing the file type from .png to .jpg but it makes no difference.
I am developing one form in jsf/primefaces. I have two inputText(inputMask) for e.g moble number and telephone number. I want to restrict the user to put only one of these two fields . That means if user starts putting value in mobile no. then telephone no. field should be disabled and if user starts putting value in telephone no. then mobile no. field should be disabled.
I have a class that extends JFrame, within that, i have set up JPanel where within that i have four JComboBoxes, I am to enable this JPanel and its JComboBoxes at the end of a method
The code for that method is:
private void tableNumberJComboBoxItemStateChanged() { // load data for table try { // get data for table myResultSet = myStatement.executeQuery("SELECT * FROM" + "restauranttables WHERE tableNumber = " + Integer.parseInt( selectedTableNumber));
[Code] ....
I am not sure how to enable this JPanel? I have another Jpanel to Disable but one question at a time i suppose.
I have a website which requires login. After I enter username and password and click login button, a new page is loaded. In that page I have a username in the right up corner. When the user clicks logout button, Session.Clear() method is called and also Response.Redirect(" to login page "). It works OK, but the problem appears when I then click Back button in the browser. It gets me back to previous page with the username in the right up corner. Insted, I would like to show message asking user to enter password again so he can login properly.
I want my jrame should not be resized when clicking on maximize button of window.and for this i have put setResizable(false)in the constructor of class which extends Jframe.
I am learning Java but have a strong C# background. I am trying to figure out the syntax to do this in Java. In C# I would do the following to enable all text boxes in a panel
private void EnableAll() { foreach (Control ctrl in Panel1.Controls) { if (ctrl is Textbox) ((Textbox)ctrl.Enabled = true; } }
Is there something similar I can do in Java to do the same thing.
I want to disable the read write execute permissions for the users on C:/ drive. i.e. to disable their Administrator rights. How can I do it using Java?
I'd like to enable/disable a jpanel and it's entire contents in one fell swoop. I could of course call each component's .setEnabled() method, but I figured there must be a better way!
I have created one dataTable in page and shown some columns but I want to show only those columns which have entries ( if any column doesn't have record then it should not be displayed on the page.) . How should I put validation on this and display table.
