Function Documentation

filter_result windowEventFilter (BMessage * msg, BHandler ** target, BMessageFilter * msgFilter)

The filter function for window-related events.

We don't want to break the native event chain, we just insert ourselves between message reception and message dispatch to the native objects

message loop -> [our MessageFilter] -> DispatchMessage -> object-oriented handlers

filter_result viewEventFilter (BMessage * msg, BHandler ** target, BMessageFilter * msgFilter)

The filter function for view-related events.

We don't want to break the native event chain, we just insert ourselves between message reception and message dispatch to the native objects

message loop -> [our MessageFilter] -> DispatchMessage -> object-oriented handlers

This filter is added on view registration (see evtRegisterSource)

int TranslateEvent (BMessage * msg)

Translate native BeOS events to Java events.

this is the core routine of the event system, if some event doesn't get to the proper target, please look here or into viewEventFilter and windowEventFilter

jobject __cdecl Java_java_awt_Toolkit_evtInit (JNIEnv * env, jclass clazz)

jobject __cdecl Java_java_awt_Toolkit_evtGetNextEvent (JNIEnv * env, jclass clazz)

Used by the AWT dispatcher thread to fetch events from the native layer.

jobject __cdecl Java_java_awt_Toolkit_evtPeekEvent (JNIEnv * env, jclass clazz)

just a dummy for the linker.

jobject __cdecl Java_java_awt_Toolkit_evtPeekEventId (JNIEnv * env, jclass clazz, jint id)

just a dummy for the linker.

void __cdecl Java_java_awt_Toolkit_evtSendWMEvent (JNIEnv * env, jclass clazz, jobject evt)

Force context change to dispatcher thread.

void __cdecl Java_java_awt_Toolkit_evtWakeup (JNIEnv * env, jclass clazz)

Wake up the event dispatcher thread.

jint __cdecl Java_java_awt_Toolkit_evtRegisterSource (JNIEnv * env, jclass clazz, KWnd * wnd)

Insert a KWnd widget among the event handlers.

jint __cdecl Java_java_awt_Toolkit_evtUnregisterSource (JNIEnv * env, jclass clazz, KWnd * wnd)

Remove widget from the event handlers.

void recurseView (BView * v, BMenu * menu)

int32 InspectHierarchy (BMessage * msg)

Shows a popup menu which represents the hierarchy of native widgets.

Called from viewEventFilter and windowEventFilter for debugging purposes.

KWnd * getWnd (BHandler * target)

Get the KWnd object for target.

!!! once fixed, move to toolkit.hpp as an inline
