EmbeddedBrowserPrototypingJWebPane

Prototyping JWebPane integration (May/2009 - June/2009)

JCGJavaFXWebkit

- uses Swing's default look and feel to render some HTML widgets (buttons, combo boxes etc) - this means the rendering looks different on different OS/LaF combinations and definitely does not render nice as native browsers

- noticeably slower rendering and page scrolling in comparison to a native browser solution

- experienced JVM crashes when playing with the prototype

- problems with keyboard input (e.g. ENTER in a search field did not work, TAB does not move keyboard focus between input fields)

- cookies are not persisted (e.g. login to netbeans.org websites does not work)

- no API for cookies management

- JavaScript support not working 100% (e.g. download page on netbeans.org does not detect and set your OS as the default target platform for the download)

- doesn't work well with some browser plugins, e.g. Flash (as of June 30th)

- doesn't allow manipulations with HTML document (no access to DOM tree) (as of June 30th)

- doesn't work on Windows Vista 64bit

- native binaries must be placed in netbeans/bin folder when running under Windows XP and in JDK's bin folder when running under Linux

- not possible to locate selected element in DOM tree (required to implement pop-up menu)

- no SVG support

- OutOfMemoryError when setting fontsize:
