I hate self-deleting classes, but the dialog is fire-and-forget, so I don't see
a clear alternative.

+class ManageCertificatesDialog : public ui::BaseShellDialogImpl {
+ public:
+  explicit ManageCertificatesDialog(WebContents* web_contents)
+      : ui_task_runner_(base::MessageLoopForUI::current()->task_runner()) {

+    run_state_ = BeginRun(parent);
+    run_state_.dialog_thread->message_loop()->PostTask(

[mmenke, 2015/07/23 20:03:34]

PostTaskAndReply?  (You'll need to use task_runner() instead of message_loop(),
I believe)

[davidben, 2015/07/23 20:21:55]

Done.

+        base::Bind(&ManageCertificatesDialog::Show, base::Unretained(this)));

+  ~ManageCertificatesDialog() override {}

+    ::CryptUIDlgCertMgr(&cert_mgr);
+    DisableOwner(run_state_.owner);

This seems kinda unnecessary since we're not doing anything with the result, but
I didn't want to call EndRun with it enabled in case that confused anything.

[mmenke, 2015/07/23 20:03:34]

Doesn't BeginRun already do this?

[davidben, 2015/07/23 20:21:55]

BeginRun disables it, but CryptUIDlgCertMgr will re-enable it, so DisableOwner
exists to let you keep it disabled while the response is in transit.

We don't actually care about this. I just wasn't sure if EndRun (which
internally re-enables the window) would break, so I matched other callers. Do
you or ananta know if this is okay?

[ananta, 2015/07/23 20:32:57]

Does CryptUIDlgCertMgr display a modal dialog?. From the description it seems
that it does, and if yes then the parent window would not get any input or
activation messages anyways? 

[mmenke, 2015/07/23 20:34:29]

Enabling an already enabled window should be fine.

[davidben, 2015/07/24 22:43:35]

I was just going by the documentation of DisableOwner and how SelectFileDialog
uses it:
https://code.google.com/p/chromium/codesearch#chromium/src/ui/shell_dialogs/b...

Removed.

+  }
+
+  void DialogClosed() {
+    EndRun(run_state_);

[mmenke, 2015/07/23 20:03:34]

Could you just do this in the destructor, and use a scoped_ptr in your putative
PostTaskAndReply?  Having something take ownership of itself in its constructor
seems a little weird (Though that's what you're implicitly doing), so could make
a separate method to do that after construction or something.

[davidben, 2015/07/23 20:21:55]

Done. Made it no longer self-owning.
