1155ca9f WB |
60 | // The interval time of the content is dynamically assigned from the screen width and trace duration. |
61 | // However, on very big trace (more than 1 hour), we could end up with time interval that are > 1 seconds, | |
62 | // which is not very precise. | |
63 | // An algorithm need to be implemented to make sure we "increase" the number of interval in the content if | |
64 | // their precision is getting too bad. | |
65 | // | |
66 | // 2- Make sure all control are thread safe (bug 309348) | |
544fe9b7 WB |
67 | // Right now, all the basic controls (i.e. Text and Label) are sensible to "Thread Access Exception" if |
68 | // updated from different threads; we need to carefully decide when/where to redraw them. | |
69 | // This is a real problem since there is a lot of thread going on in this view. | |
70 | // All basic control should be subclassed to offer "Asynchronous" functions. | |

352 | // *** HACK *** |
353 | // To align properly AND to make sure the canvas size is fixed, we NEED to make sure all "section" of the | |
354 | // gridlayout are taken (and if possible of a fixed size). | |
355 | // However, SWT is VERY VERY DUMB and won't consider griddata that contain no control. | |
356 | // Since there will be missing a section, the SelectedWindowCanvas + NbEventsText will take 3 spaces, but | |
357 | // startTimeText + stopTimeText will take only 2 (as if empty the other griddata of 1 will get ignored). | |
358 | // StopTime will then take over the missing space; I want to align "stopTime" right on the end of canvas, so | |
359 | // the added space to stop time would make it being aligned improperly | |
360 | // So I NEED the empty griddata to be considered! | |
361 | // Visually : | |
362 | // |---------------|---------------|-----------| | |
363 | // |SelectionCanvas SelectionCanvas|NbEventText| | |
364 | // |SelectionCanvas SelectionCanvas|NbEventText| | |
365 | // |---------------|---------------|-----------| | |
366 | // |StartTime | StopTime| ??? | | |
367 | // |---------------|---------------|-----------| | |
368 | // | |
369 | // So since SWT will only consider griddata with control, | |
370 | // I need to create a totally useless control in the ??? section. | |
1155ca9f | 371 | // That's ugly, useless and it is generally a bad practice. |
7ef9ae3f WB |
372 | // |
373 | // *** SUB-HACK *** | |
374 | // Other interesting fact about SWT : the way it draws (Fill/Expand control in grid) will change if | |
1406f802 | 375 | // the control is a Text or a Label. |
7ef9ae3f WB |
376 | // A Label here will be "pushed" by startTime/stopTime Text and won't fill the full space as NbEventText. |
377 | // A Text here will NOT be "pushed" and would give a nice visual output. | |
378 | // (NB : No, I am NOT kidding, try it for yourself!) | |
379 | // | |
380 | // Soooooo I guess I will use a Text here. Way to go SWT! | |
1155ca9f WB |
381 | // Downside is that disabled textbox has a slightly different color (even if you force it yourself) so if I want |
382 | // to make the text "invisible", I have to keep it enabled (but read only), so it can be clicked on. | |
