[racket-dev] mouse motion events in Linux
Dear list, Recently I noticed that on Linux, the canvas only receives mouse motion events if some mouse button is pressed. Since this is not mentioned in the documentation I assume this behaviour was not intended, please correct me if wrong. The cause of this behaviour is the use of the flag GDK_BUTTON_MOTION_MASK in collects/mred/private/wx/gtk/canvas.rkt This flag indeed means only send motion events if a button is down. If all motion request are desired the flag GDK_POINTER_MOTION_MASK should be used instead. I have sent a pull request for this one-line change on github and would recommend that it gets merged, if indeed receiving all motion events is the intended behaviour. Thanks, Stephan _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
Re: [racket-dev] mouse motion events in Linux
Short answer: change pushed. Long answer: At one point, I changed GDK_POINTER_MOTION_MASK to GDK_POINTER_MOTION_HINT_MASK. My impression from the documentation and from trying it out was that it generated helpfully fewer mouse-movement events. Instead, it seems to generate zero mouse-movement events --- so I must misread the docs and did something else wrong when trying it out. Meanwhile, the problem that the switch seemed to solve seems to have been fixed some better way, since things work fine with GDK_POINTER_MOTION_MASK.
