Bug 57480 – Inspector doesn't come to the front when a breakpoint is hit in the debugger in WebKit2

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Adam Roben (:aroben)]

To reproduce:

1. Go to http://build.webkit.org/LeaksViewer/
2. Open the Inspector's debugger and put a breakpoint in LeaksViewer.urlPromptButtonClicked in LeaksViewer.js
3. Click back on the main page
4. Click on the "Fetch leaks" button

The breakpoint is hit in the debugger, but the Inspector doesn't come to the front. In WebKit1, it does come to the front.

I think the bug is caused by WebInspectorFrontendClient::bringToFront being unimplemented.

If we implement this, and remove the code that immediately shows the Inspector window when it's first created, then the Inspector window might stop showing up when running run-webkit-tests.

[Timothy Hatcher]

The bringToFront function is only used after the inspector has a window created by the client. The client is required to show it the first time. So we can't remove the code to immediately show it, unless we refactor things.

I thought WebKit1 didn't immediately show it, but maybe I'm wrong.

I think check-webkit-style doesn't know about https: for short bug URLs. You should file a bug about that.

You could put this FIXME in the Windows code, too.

> Source/WebKit2/UIProcess/win/WebInspectorProxyWin.cpp:197

I don't think this will be sufficient on Windows. I think this would do the trick instead:

::SetWindowPos(m_inspectorWindow, HWND_TOP, 0, 0, 0, 0, SWP_SHOWWINDOW | SWP_NOMOVE | SWP_NOSIZE);

I file a bug about the style bot a while ago.

Landed in r84424 with Adam's feedback applied.
