* The GNOME HIG:
|
|

|
|
* http://developer.gnome.org/projects/gup/hig/1.0/windows.html#alert-windows
|
|
*
|
|
* says that the title should be empty for alert boxes, so there's "less
|
|
* visual noise and confounding text."
|
|
*
|
|
* The Windows HIG:
|
|
*
|
|
* http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwue/html/ch09f.asp
|
|
*
|
|
* says it should
|
|
*
|
|
* ...appropriately identify the source of the message -- usually
|
|
* the name of the object. For example, if the message results
|
|
* from editing a document, the title text is the name of the
|
|
* document, optionally followed by the application name. If the
|
|
* message results from a non-document object, then use the
|
|
* application name."
|
|
*
|
|
* and notes that the title is important "because message boxes might
|
|
* not always the the result of current user interaction" (e.g., some
|
|
* app might randomly pop something up, e.g. some browser letting you
|
|
* know that it couldn't fetch something because of a timeout).
|
|
*
|
|
* It also says not to use "warning" or "caution", as there's already
|
|
* an icon that tells you what type of alert it is, and that you
|
|
* shouldn't say "error", as that provides no useful information.
|
|
*
|
|
* So we give it a title on Win32, and don't give it one on UN*X.
|
|
* For now, we give it a Win32 title of just "Wireshark"; we should
|
|
* arguably take an argument for the title.
