Linux 为什么 XGrabKey 会生成额外的聚焦和聚焦事件

最后，正如大家所知，linux意味着自由，我修改了xserver以摆脱grab风格的focusout:

sudo apt-get build-dep xorg-server
apt-get source xorg-server
cd xorg-server-*
#modify or patch dix/events.c: comment off "DoFocusEvents(keybd, oldWin, grab->window, NotifyGrab);" in ActivateKeyboardGrab(), comment off "DoFocusEvents(keybd, grab->window, focusWin, NotifyUngrab);" in DeactivateKeyboardGrab()
sudo apt-get install devscripts
debuild -us -uc    #"-us -uc" to avoid the signature step
cd ..
sudo dpkg --install xserver-xorg-core_*.deb
#clear dependencies:
sudo apt-mark auto $(apt-cache showsrc xorg-server | grep Build-Depends | perl -p -e 's/(?:[\[(].+?[\])]|Build-Depends:|,|\|)//g')
sudo apt-get autoremove

我还需要go 掉gtk上下文菜单中的XGrabKeyboard:

sudo apt-get build-dep gtk+2.0
apt-get source gtk+2.0
cd gtk+2.0-*
#modify or patch it: add "return TRUE;" in first line of popup_grab_on_window() of gtk/gtkmenu.c
dpkg-source --commit
debuild -us -uc  #"-us -uc" to avoid the signature step, maybe need: sudo apt-get install devscripts
cd ..
sudo dpkg --install libgtk2.0-0_*.deb
#clear dependencies:
sudo apt-mark auto $(apt-cache showsrc gtk+2.0 | grep Build-Depends | perl -p -e 's/(?:[\[(].+?[\])]|Build-Depends:|,|\|)//g')
sudo apt-get autoremove

现在是我的董事会.py工作得很好.
