I don't know if this is what Scott meant when he said to "promote the common
code", but there's still a bunch of repetition between this and
PanelExtensionWindowController::CreateWindowValue(). It seems like a lot of
properties can be set from a BaseWindow instance.

Perhaps the ExtensionWindowController::CreateWindowValue implementation should
be implemented in terms of BaseWindow (for things like session ID, bounds,
incognito, etc.) , and subclasses could override it, call it, and add any
additional properties that they need.

I forgot to update my comment. It turns out that there is not that much that is
actually common here (only two properties: Id and Focused). I opted not to put
those in a base class implementation, I personally find that pattern confusing
and error prone outside of constructors, but could do so if that is preferred. I
did add a helper function for setting the bounds properties.

+  DictionaryValue* result = new DictionaryValue();
+  result->SetInteger(keys::kIdKey, browser_->session_id().id());
+  result->SetBoolean(keys::kIncognitoKey,
+                     browser_->profile()->IsOffTheRecord());
+  result->SetBoolean(keys::kFocusedKey, window()->IsActive());
+
+  gfx::Rect bounds;
+  if (window()->IsMaximized() || browser_->window()->IsFullscreen())
+    bounds = window()->GetBounds();
+  else
+    bounds = window()->GetRestoredBounds();
+  result->SetInteger(keys::kLeftKey, bounds.x());
+  result->SetInteger(keys::kTopKey, bounds.y());
+  result->SetInteger(keys::kWidthKey, bounds.width());
+  result->SetInteger(keys::kHeightKey, bounds.height());
+
+  result->SetString(keys::kWindowTypeKey,
+                    ExtensionTabUtil::GetWindowTypeText(browser_));
+  result->SetString(keys::kShowStateKey,
+                    ExtensionTabUtil::GetWindowShowStateText(browser_));
+
+  return result;
+}
+
+base::DictionaryValue*
+BrowserExtensionWindowController::CreateWindowValueWithTabs() const {
+  DictionaryValue* result = CreateWindowValue();
+
+  result->Set(keys::kTabsKey, ExtensionTabUtil::CreateTabList(browser_));
+
+  return result;
+}
+
+bool BrowserExtensionWindowController::CanClose(
+    ExtensionWindowController::Reason* reason) const {
+  // Don't let an extension remove the window if the user is dragging tabs
+  // in that window.
+  if (!browser_->IsTabStripEditable()) {
+    *reason = ExtensionWindowController::REASON_TAB_STRIP_NOT_EDITABLE;
+    return false;
