python 2.7 - QMenu context menu initial size too small and w/o content in QtOpenGL.QGLWidget -


i using pyqt 4.8.6 bindings python 2.7.9. create context menu inside qtopengl.qglwidget:

class openglwidget(qtopengl.qglwidget):     def __init__(self, parent=none):         qtopengl.qglwidget.__init__(self, parent)         #    context menu properties         self.setcontextmenupolicy(qtcore.qt.customcontextmenu)      def contextmenuevent(self, event):         self.popmenu = qtgui.qmenu(parent=self)         print self.popmenu.sizehint()         print self.popmenu.size()         self.popmenu.setfixedwidth(100)         self.popmenu.setfixedheight(100)         print self.popmenu.size()         self.popmenu.addaction(qtgui.qaction('refresh', self.updategl()))         self.popmenu.addseparator()         self.popmenu.addaction(qtgui.qaction('test2', none))         self.popmenu.exec_(event.globalpos())      def mousepressevent(self, event):         self.last_pos = qtcore.qpoint(event.pos())          if event.button() == qtcore.qt.rightbutton:             self.contextmenuevent(event)

it prints out:

>>> pyqt4.qtcore.qsize(2, 2) >>> pyqt4.qtcore.qsize(100, 30) >>> pyqt4.qtcore.qsize(100, 100)

and context menu looks empty, below:

empty context menu

i know how set context menu size adjustable , seen initial settings? have ideas why there no menu text (function) inside? use context menu in tree view , there works ok, here have problem. , if dons set fixed menu size, menu smaller letters of coordinate system axes.

it looks way defining actions not quite ok, although found in example somewhere. context menu items (actions) should defined as:

_updateglaction = popmenu.addaction("refresh") _updateglaction.triggered.connect(self.repaintgl)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
