2019-09-11Add MouseableJeffas
This adds the Mouseable interface. When this is implemented for a component that item can accept and process mouseevents. At the top level when a mouse event is received it is passed to the grid's handler and then it trickles down until it reaches a component that can actually handle it, such as the tablist, dirlist or msglist. A mouse event is passed so that components can handle other things such as scrolling with the mousewheel. The components themselves then perform the necessary actions. Clicking emails in the messagelist opens them in a new tab. Textinputs can be clicked to position the cursor inside them. Mouseevents are not forwarded to the terminal at the moment. Elements which do not handle mouse events are not required to implement the Mouseable interface.
2019-07-25Fix grid creating too large subcontextsJeffas
The grid was not checking there was enough space for the cells so would just attempt to create subcontexts that don't actually fit. This attempts to use the remaining space and then if there is no space then it just skips drawing this cell.

2019-07-17Fix grid widths when using weighted widthsJeffas
If the column weights do not collectively divide the extent of the grid layout then some width was not used and so would not be redrawn, resulting in previous drawings showing through. This fixes this by checking if there is any remainingExact width and if there is it is assigned to the weighted columns by their proportion from left to right.

2019-05-05lib/ui: fix Grid race conditionSimon Ser
This was is more complicated than others. The cells list is accessed by multiple goroutines: - Some change the Grid's contents via AddChild/RemoveChild - Some call Draw - Some invalidate the grid via Invalidate Invalidate calls are tricky to handle because they will also invalidate all child cells. This will inturn trigger the cellInvalidated callback, which needs to read the list of cells. For this reason, we use a sync.RWLock which allows multiple concurrent reads. Below is the race fixed by this commit.

2019-04-27lib/ui: introduce InvalidatableSimon Ser
Many Drawable implementations have their own Invalidate and OnInvalidate functions, with an unexported onInvalidate field. However OnInvalidate and Invalidate are usually not called in the same goroutine. This results in a race on this field, e.g.: Read at 0x00c000094748 by goroutine 7: git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList.func1() /home/simon/src/aerc2/widgets/dirlist.go:85 +0x56 git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start.func1() /home/simon/src/aerc2/widgets/spinner.go:93 +0x1bb Previous write at 0x00c000094748 by main goroutine: [failed to restore the stack] Goroutine 7 (running) created at: git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start() /home/simon/src/aerc2/widgets/spinner.go:46 +0x8f git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList() /home/simon/src/aerc2/widgets/dirlist.go:37 +0x286 git.sr.ht/~sircmpwn/aerc2/widgets.NewAccountView() /home/simon/src/aerc2/widgets/account.go:50 +0x5ca git.sr.ht/~sircmpwn/aerc2/widgets.NewAerc() /home/simon/src/aerc2/widgets/aerc.go:60 +0x800 main.main() /home/simon/src/aerc2/aerc.go:65 +0x33e To fix this, introduce a new type, Invalidatable, which protects the field. Unfortunately the Drawable must be passed to the callback function in Invalidate, so we still need to re-implement this in each Invalidatable user.
