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
