| 19 // A class, attached to WebContentses in browser windows, that is the |
| 20 // JavaScriptDialogManager for them and handles displaying their dialogs. |
| 21 // |
| 22 // This is the primary mechanism for implementing auto-dismissing dialogs, |
| 23 // dialogs that close when the user switches away to a different tab. Because |
| 24 // JavaScript dialogs are synchronous and block arbitrary sets of renderers, |
| 25 // they cannot be made tab-modal. Therefore the next best option is to make them |
| 26 // auto-closing, so that they never block the user's access to other renderers. |
| 27 // |
| 28 // See http://bit.ly/project-oldspice for more details. Note that only part |
| 29 // one of that design is implemented. |
