Re: [webkit-dev] Fwd: ［GTK］Scroll deficiency
Hi, I am happy to hear that you solve the issue. I am also sorry to say i can not search the bug report, and never submit the patch with my sloth. -Xiong 2009/6/2 Srinivas Rao M Hamse msrini...@gmail.com Hi Xiong, My platform is WebKiton gtk+directfb. I am noticing that the issue is still present in the current Webkit nightly R-44111 build. I saw your sugested patch : In function ChromeClient::scroll() // gdk_window_move_region(window, moveRegion, delta.width(), delta.height()); // gdk_region_offset(moveRegion, delta.width(), delta.height()); gdk_window_move_region(window, moveRegion, moveRect.width, moveRect.height); gdk_region_offset(moveRegion, moveRect.width, moveRect.height); After applying it, I am not finding the scroll deficiency issue. I wish to know if this fix is working, why is it not landed yet. What is the plan for this bug. What is the bug number for Gtk+Directfb platform.

Re: [webkit-dev] JSObjectCallAsFunctionCallback question
Hi, Su Yes, this is the key point of the problem. In my program, many Object use the same staticFunc entry[Program Architecture]. So, in the getValue_cb callback function, we need do extra two things: 1.Get the Object name, here is myObject; [WE CAN NOW] 2.Get the propertyName of the method, here is getValues; [WE CAN NOT NOW] After both get the Object and method's name, we can identify another callback function. Therefore, implement a way to get the propertyName of the method via 'function object' is needed.

[webkit-dev] JSObjectCallAsFunctionCallback question
Hello all,
I have implement a JS object named myObject with the JavaScriptCore(JSC)
API, and it has a method named getValues(), called as following:
myObject.getValues();
And it define like this:
JSStaticFunction staticFunc[] = {
{getValues, getValue_cb, kJSPropertyAttributeReadOnly},
{NULL, NULL, NULL, NULL}
};
The prototype of getValue_cb callback function like this:
JSValueRef getValue_cb(JSContextRef context, JSObjectRef function,
JSObjectRef object,
size_t argumentCount, const JSValueRef arguments[],
JSValueRef *exception)
I have two problems about the getValue_cb callback function:
1what is the purpose of the JSObjectRef function variable? In my case,
we never use.
2In this function, i want to get the propertyName of the method, in this
case, we need getValues, can be implemented ?
Appreciate any clues~
Thanks.

[webkit-dev] Background color issue
Dear all, I am working webkit over directfb backend on arm platform - using GtkLauncher. The problem I face is that the background color of loading image is always WHITE, i am really want to be BLACK. BTW: I use the gtk_widget_modify_bg() to change color of GTKWINDOW and WebKitWebView, but it looks like valueless. Also, i connect to expose-event signal for WebKitWebView and setting the background color in following code: [ cairo_set_source_rgb(cr, 0, 0, 0); cairo_paint(cr); ] This way was failed also. The Gtk+ API does not change the background color, so may be the webkit kernel do something i think. Any ideas where to look to fix this issue ?
