JxBrowser 7.21 has been released! We’ve extended API with new features, added important fixes and improvements.
What’s New
DOM Image Raw Bytes
Find all the images on a web page or a specific image and access its raw bytes using the new com.teamdev.jxbrowser.dom.ImageElement interface:
document.findElementById("image").ifPresent(element -> {
if (element instanceof ImageElement) {
ImageElement image = (ImageElement) element;
Bitmap bitmap = image.contents();
Size size = bitmap.size();
byte[] pixels = bitmap.pixels();
}
});
It’s useful if you need to extract the images from a web page and store them on a local file system, RAM, or database.
DOM CustomEvent Detail
Listen to the custom DOM events and access their payload:
// Listen to the events of the given custom event type.
element.addEventListener(EventType.of("MyEvent"), event -> {
// The MyEvent event has been received.
if (event instanceof CustomEvent) {
CustomEvent customEvent = (CustomEvent) event;
JsObject payload = customEvent.detail();
}
}, false);
Quality Enhancements
- The upload POST data was corrupted because of some extra bytes.
- Drop data from dataTransfer was lost on macOS.
- Subfolders were treated as files when selecting a folder in the
OpenFoldercallback. BrowserViewwas blank and threw “Failed to get native widget ID” exception in JavaFX.BrowserViewwas blank and threw “Failed to detect the GTK version” exception in SWT in Linux.- Passing
nullorundefinedfrom JavaScript to Java resulted inIllegalArgumentException. - Network events and callbacks
didn’t contain
sec-ch-ua,sec-ch-ua-mobile, andsec-ch-ua-platformheaders when a web page was loaded viaNavigation.loadUrl(). - Chromium unexpectedly released
Browserinstance when reaching the memory limit. This is unwanted behavior for the library, and we disabled it.
