#780 GFX View doesn't work with 4.3pre8

[Matthieu Casanova]

Hi, the browser action is broken, it can be fixed
using this action

view.getDockableWindowManager().addDockableWindow(GfxViewPlugin.NAME);
browser = view.getDockableWindowManager().getDockable("vfs.browser");
VFSFile[] entries = browser.getSelectedFiles();
if (entries.length==0 || entries[0].getType()!=VFSFile.FILE) {
JOptionPane.showMessageDialog(view,"GfxView shows only a selected picture file");
}
else {
view.getDockableWindowManager().getDockable(GfxViewPlugin.NAME).loadImage(entries[0].path);
}
