| 20 // Draws and maintains Translate Infobar GUI. | |
| 21 // The translate bar can be in one of 3 states: | |
| 22 // 1. "Before Translate" - source language popup and translate/cancel buttons | |
| 23 // visible. | |
| 24 // 2. "Translating" - "Translating..." status text visible in address bar. | |
| 25 // 3. "After Translation" - source & target language popups visible. | |
| 26 // | |
| 27 // The following state transitions are supported: | |
| 28 // 1->{2,3} | |
| 29 // 2<->3 | |
| 30 // i.e. Once you've transitioned out of "Before Translate" mode you can't switch | |
| 31 // back, however all other state transitions are supported. | |
| 32 // | |
