Archived from groups: linux>debian>bugs>dist (more info?)

Package: libgtk2.0-0
Version: 2.18.3-1
Severity: important

DVswitch has a custom widget which supports drag selection and
extension, so its event mask is:

GDK_BUTTON_PRESS_MASK | GDK_BUTTON_RELEASE_MASK
| GDK_BUTTON1_MOTION_MASK | GDK_BUTTON2_MOTION_MASK

It also adds and removes modal grab as the mouse button is pressed and
released, so that it can detect the end of a drag outside the window.

Today I found that this widget no longer receives motion events, only
press and release events. Adding GDK_POINTER_MOTION_MASK brings back
motion events, but I do not want to receive them while no buttons are
pressed! This is a regression from 2.16, possibly resulting from the
extensive changes to support XInput.

Ben.
