po/splash screen #17552
Conversation
Give the user feedback on the startup process as early as possible so that they aren't left wondering whether darktable is actually starting successfully (opening a large library can take multiple seconds even on SSD, and crawling a large collection for updated sidecar could potentially take over a minute). Also add pref to disable the splash screen.
This allows the splash screen to be properly styled from the beginning, so that it does not change color/font in the middle of startup.
This lets the darktable GUI display before the potentially very lengthy crawl, and affords the future opportunity to add code to cancel the crawl or at least display the directory names as they are crawled. Some other adjustments to avoid a UI hang when doing the crawl after LUA initialization fires up the script installer.
The sidecar crawler now updates with percentage completed once per second. The crawling had to be moved back before LUA startup to avoid hanging the UI.
this permits GUI initialization to proceed without showing an empty main window with a default geometry before we know the actual configured geometry (which may even be on a different display).
Unfortunately, on some systems minimizing or hiding the main window during initialization results in the main window remaining hidden or iconified. We'll have to live with a brief display of an empty window....

Just tested this the first time, very nice. One minor thing, i would expect the logo to be centered on the main window. Would that be possible/desired? |

The splashscreen window is centered on the screen, while the darktable main window is sized/positioned as it was at last shutdown. I had made some attempts to keep the main window hidden until all the initializations were complete, but while both attempts worked on my machine, each had problems on someone else's. My third attempt in my most recent commit on the PR is to size the main window so that the splashscreen hides it until the splashscreen is closed, then resize the finished main window to the stored geometry. That makes it look like it pops open just as the splashscreen vanishes. |
