38 | * Testing a HiDPI display is difficult without running in a HiDPI display. | |
39 | * The gathering of screen size and resolution performed by jalview.bin.HiDPISetting | |
40 | * is now farmed out into a separate class jalview.bin.ScreenInfo so it can be more | |
41 | * easily Mocked in tests. | |
42 | * Two sets of tests are performed. | |
43 | * 1) testLinuxScalePropertyToActualTransform() sets the property that HiDPISetting | |
44 | * uses (via jalview.bin.Launcher or getdown) to scale up Jalview, and then looks at | |
45 | * the alignment panel graphics2d transform to see if it's been scaled by the same | |
46 | * amount (in this case 4 -- unlikely to happen by accident!). | |
47 | * 2) testHiDPISettingInit() which tests the calculation that HiDPISetting uses to | |
48 | * decide from apparent screen information (mocked using Mockito in the tests) what | |
49 | * scaling factor to set (it doesn't actually set it, just suggests it to | |
50 | * jalview.bin.Launcher) | |
