Comment #108 on issue 20 by a...@chromium.org: Taskbar autohide doesn't work if you enable it while Chrome is maximized http://code.google.com/p/chromium/issues/detail?id=20
Here's some background: Basic problem here is that chrome top level windows don't have any non-client area except borders. When such window is maximized (even using DefWindowProc), the task bar performs a check to see if the currently maximized window is a 'full screen' app. A 'full screen app' is something that has its entire client area stretched to the screen. A normal window usually has some non-client elements like a title bar or menu so the client area doesn't stretch the entire screen. Since that's not the case for chrome, the taskbar detects that it's a full screen application and hides itself behind maximized chrome window. Previous fixes have been workarounds to reduce the client area by 1 pixel so that we don't get marked as full screen apps. This is done by handling WM_GETMINMAXINFO and reducing the size of the client area. However, things work little differently on Vista and even if we return the reduced client area, the subsequent handling of WM_SYSCOMMAND of SC_MAXIMIZE reverts it. The right thing to do here is probably implement WM_SYSCOMMAND for SC_MAXIMIZE. This implementation is non-trivial. On vista, I added another hack to reduce the client area by a larger amount so that the DefWindowProc of WM_SYSCOMMAND for SC_MAXIMIZE would honor the new size. This hack has its own set of drawbacks. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
