Releases/FeatureXULRunnerAPIChanges

This page is intended for tracking changes in mozilla API between the current one (firefox/gecko-libs 1.8) and the upcoming XUL Runner API (gecko-libs 1.9). It should help developers to port their gecko base applications to XUL Runner .

XUL Runner API Changes

String API

String API has been heavily changed. Internal strings are not exported now and you have to use only the frozen string interface. See [1] and [2] for details.

Printing API

gtkmozembed

gtkmozembed is initialized by different way. You have to use gtk_moz_embed_set_path() instead of the old gtk_moz_embed_set_comp_path().

There's an code example from chmsee package:


gtk_moz_embed_set_path(GECKO_LIB_ROOT);
#else
gtk_moz_embed_set_comp_path(GECKO_LIB_ROOT);
#endif

Other changes

NS_LogInit()/NS_LogTerm() has been added for early logging.

Unresolved problems

nsEscape - not exported, unstable
Drag and Drop - not exported, in unstable (but seems to compile at least)
NSS dialogs - changed
nsIPassword - not exported, unstable
