python - PyQt: tab order not working for a simple custom widget -

-

i have made custom widget consisting of spinbox , checkbox. widget delegates focus spinbox using setfocusproxy. checkbox should not focus.

my problem when use widget in layout, qt tab order not work expected. below minimal working example. in example, focus should move var 1->var 3->var 2->var 4 when pressing tab key, doesn't.

if replace checkspinboxes regular qt widgets (e.g. qcheckboxes), works expected. using checkbox focus proxy seems make tab order work properly. problem seems using spinbox focus proxy. 

from pyqt4 import qtgui, uic, qtcore import sys  class checkspinbox(qtgui.qwidget):      def __init__(self, parent=none, label=none):         super(self.__class__, self).__init__(parent)         self.degspinbox = qtgui.qspinbox()         self.normalcheckbox = qtgui.qcheckbox(label)         layout = qtgui.qhboxlayout(self)         layout.addwidget(self.degspinbox)         layout.addwidget(self.normalcheckbox)         self.degspinbox.setfocuspolicy(qtcore.qt.strongfocus)         self.normalcheckbox.setfocuspolicy(qtcore.qt.nofocus)         self.setfocuspolicy(qtcore.qt.strongfocus)         self.setfocusproxy(self.degspinbox)  class entryapp(qtgui.qwidget):      def __init__(self):         super(self.__class__, self).__init__()         layout = qtgui.qgridlayout()         self.sp1 = checkspinbox(label='var 1')         self.sp2 = checkspinbox(label='var 2')         self.sp3 = checkspinbox(label='var 3')         self.sp4 = checkspinbox(label='var 4')                  layout.addwidget(self.sp1,1,1)         layout.addwidget(self.sp2,1,2)         layout.addwidget(self.sp3,2,1)         layout.addwidget(self.sp4,2,2)          self.setlayout(layout)          self.settaborder(self.sp1, self.sp3)         self.settaborder(self.sp3, self.sp2)         self.settaborder(self.sp2, self.sp4)  def main():     app = qtgui.qapplication(sys.argv)     eapp = entryapp()      eapp.show()     app.exec_()  if __name__ == '__main__':     main()

ok, seems rather longstanding qt bug, settaborder() not handle widgets focus proxy. bug report in https://bugreports.qt.io/browse/qtbug-10907

simplest workaround (at least case above): explicitly put focus proxy on tab order chain, so: self.settaborder(self.sp1.focusproxy(), self.sp3.focusproxy())

i'm using react-router first time , don't know how think in yet. here's how i'm loading components in nested routes. entry point .js reactdom.render( <router history={hashhistory} > <route path="/" component={app}> <route path="models" component={content}> </route> </router>, document.getelementbyid('app') ); app.js render: function() { return ( <div> <header /> {this.props.children} </div> ); } so child of app content component sent in. i'm using flux , app.js has state , listens changes, don't know how pass state down this.props.children. before using react-router app.js defines children explicitly, passing state natural don't see how now. using couple of react helper methods can add state, props , whatever else this.props.children render: function() { var children = react.ch...
