Comment #19 on issue 23869 by [email protected]: Renderer Crash In -
WebPopupMenuImpl::KeyEvent(WebKit::WebKeyboardEvent const&)
http://code.google.com/p/chromium/issues/detail?id=23869
Here's the code that I think is triggering the crash, from
render_widget_host_view_mac.mm:
// Display the menu.
scoped_nsobject<WebMenuRunner> menu_runner;
menu_runner.reset([[WebMenuRunner alloc] initWithItems:items]);
[menu_runner runMenuInView:parent_view_
withBounds:position
initialIndex:selected_item];
int window_num = [[parent_view_ window] windowNumber];
NSEvent* event =
webkit_glue::EventWithMenuAction([menu_runner menuItemWasChosen],
window_num, item_height,
[menu_runner indexOfSelectedItem],
position, view_rect);
if ([menu_runner menuItemWasChosen]) {
// Simulate a menu selection event.
const WebMouseEvent& mouse_event =
WebInputEventFactory::mouseEvent(event, cocoa_view_);
render_widget_host_->ForwardMouseEvent(mouse_event);
} else {
// Simulate a menu dismiss event.
NativeWebKeyboardEvent keyboard_event(event);
render_widget_host_->ForwardKeyboardEvent(keyboard_event);
}
If the renderer navigated to another page while runMenuInView: is running a
run
loop, the renderer is confused by the synthesized key/mouse event. I need
to check
how the renderer deals with this in the internal popup case. Ideally, the
renderer
could just ignore these input events.
