54 | // 1- Make sure the interval time is small enought on very big trace (bug 311930) |
55 | // The interval time of the content is dynamically assigned from the screen width and trace duration. | |
56 | // However, on very big trace (more than 1 hour), we could end up with time interval that are > 1 seconds, | |
57 | // which is not very precise. | |
58 | // An algorithm need to be implemented to make sure we "increase" the number of interval in the content if | |
59 | // their precision is getting too bad. | |
60 | // | |
61 | // 2- Make sure all control are thread safe (bug 309348) | |
544fe9b7 WB |
62 | // Right now, all the basic controls (i.e. Text and Label) are sensible to "Thread Access Exception" if |
63 | // updated from different threads; we need to carefully decide when/where to redraw them. | |
64 | // This is a real problem since there is a lot of thread going on in this view. | |

69 | // at run time. There should be a view of some kind of "menu" to allow the user to change them while executing. | |
