* Ring bell when new messages arrive 0.2.0Ben Burwell2019-07-291-0/+9
| | | | | | | | Add a "new-message-bell" option to the UI section of aerc.conf. A new hook into the message store allows the msglist widget to detect new messages being added to the displayed list. When new messages are delivered, and the new-message-bell option is enabled (as it is by default), the terminal will beep.
* Add clickable tabsJeffas2019-07-111-0/+7
| | | | | | | | | | | This introduces a new interface `Clickable`. I'd imagine this would be implemented for most widgets eventually and would allow for programs run in the terminal to also have their mouse events forwarded to them. For the tabs it was relatively simple to check that the position of the click is within the boxes for the tabs. For other components I'd imagine that some state representing their currently drawn bounding box would be useful.
* Update internal state and draw from the same goroutineSimon Ser2019-05-191-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a new Aerc.Tick function that should be called to refresh the internal state. This in turn makes each AccountView process worker events. The UI goroutine repeatedly refreshes the internal state before drawing a new frame. The reason for this is that many worker messages may need to be processed for a single frame, and drawing the UI is far slower than refreshing the internal state. This has been confirmed in my testing (calling Aerc.Tick only once per frame results in a slower display). Many synchronization code has been removed. We can now write widgets without having to care so much about races. The remaining sync users are: - widgets/spinner: the spinner value is updated from inside an internal goroutine - lib/ui/invalidatable: Invalidate may be called from any goroutine - lib/ui/grid: same - lib/ui/ui: an internal goroutine needs read access to UI.exit - worker/types/worker: Worker.callbacks is used for both worker and UI callbacks The exact goroutine requirements for Drawable have been documented.
