[OpenSmalltalk/opensmalltalk-vm] x11: emit mouse wheel events, drop the ctrl+arrow workaround (#303)
by Tom Beckmann 11 Nov '18

11 Nov '18

These changes fixed the horizontal scrolling issues for me. Cursory testing revealed no unintended sideeffects, but more testing should be done. I did not find an easy way to test if horizontal scrolling works as intended, plainly logging the events looks good, however. No image-side changes were necessary, so I would claim that the VMs for the other platforms can continue to work as normal, even with this change just on x11. Using the workaround to mark a scroll event by detecting all modifiers being pressed down instead, will require an image-side change though.

XCB as a replacement for XLib anyone?
by Eliot Miranda 10 Nov '18

10 Nov '18

Hi All, I'm taking a look at XNextEvent et al (specifically to see if meta events can be delivered on key down, not on key up) and I see that XCB is an interesting alternative to XLib. Has anyone taken a look at writing an XCB subsystem, e.g.platforms/unix/vm-display-X11_XCB? _,,,^..^,,,_ best, Eliot

At first one can see that the image I opened is in principle functional, that is, window decoration lights up on mouse-over, list items highlight when hovered, and clicks on list items work as expected (screen recording tool adds extra highlight to clicks). All of this happens using an external mouse. Around the ten second mark I switch to the MacBook touchpad and attempt a two-finger scroll. Suddenly all of the mentioned behaviors stop working, as if input was completely stalled. It is probably not a complete image freeze, because the frame counter still appears to be operational. However, I'm not even able to close the image using the red button. ![screen recording 2018-11-07 at 14 19 54](https://user-images.githubusercontent.com/29141485/48135100-36fb1400-e2… -- You are receiving this because you are subscribed to this thread.

Build Update for OpenSmalltalk/opensmalltalk-vm ------------------------------------- Build: #1478 Status: Still Failing Duration: 9 mins and 55 secs Commit: 5d0e0bc (Cog) Author: Eliot Miranda Message: CogVM source as per VMMaker.oscog-eem.2482 Slang Fix mis-handling of trailing boolean on inlining in conditionals when trailing boolean would cause the conditional to be taken. e.g. in self tryCopyingBitsQuickly ifTrue: [^nil]. tryCopyingBitsQuickly ends with ^true but the in lining code handled the trailing ^true by taking the fall-through path past the ^nil. Consequently fix a regression in the BitBlt primitive caused by cleanups in VMMaker.oscog-eem.2461. Regenerate VM files to bring source up to date after minor changes for Slang pointer type normalization in VMMaker.oscog-eem.2476.
