From dbc7b185c842f56d205808c8b6924c1b7037955b Mon Sep 17 00:00:00 2001 From: "cpu@chromium.org" Date: Fri, 2 Nov 2012 18:18:16 +0000 Subject: Support tooltips in ash windows In windows ash mode, if a tooltip is going to be presented we end up creating a desktop widget which is incorrect. The issue at hand is the widget selection here: views::NativeWidget* ChromeViewsDelegate::CreateNativeWidget( views::Widget::InitParams::Type type, views::internal::NativeWidgetDelegate* delegate, gfx::NativeView parent) { if (parent && type != views::Widget::InitParams::TYPE_MENU) return new views::NativeWidgetAura(delegate); if (chrome::GetHostDesktopTypeForNativeView(parent) == chrome::HOST_DESKTOP_TYPE_NATIVE) return new views::DesktopNativeWidgetAura(delegate); return NULL; } For a tooltip the |parent| is null and that ends up returning a views::DesktopNativeWidgetAura which is wrong and causes a crash. In ash we need to return NativeWidgetAura The alternative to this change is to have GetHostDesktopTypeForNativeView() return not chrome::HOST_DESKTOP_TYPE_NATIVE.
