(Python) Line Break for PyQt5 Menu Bar -


help needed pyqt5 menu bar:

i started getting pyqt5, , i'm making menu bar gui application. below code made menu far:

import sys pyqt5.qtwidgets import qapplication, qmainwindow, qaction, qapp   class menudemo(qmainwindow):     def __init__(self):         super().__init__()  ####################################################          # creates initial menu bar         bar = self.menubar()          # creates menu bar tabs & names them         file = bar.addmenu('file')         edit = bar.addmenu('edit')         helpme = bar.addmenu('help')          # creates actions 'file' section         new_action = qaction('new file', self)         new_action.setshortcut('ctrl+n')          open_action = qaction('open file', self)         open_action.setshortcut('ctrl+o')          save_action = qaction('save', self)         save_action.setshortcut('ctrl+s')          save_as_action = qaction('save as...', self)         save_as_action.setshortcut('ctrl+shift+s')          quit_action = qaction('quit', self)         quit_action.setshortcut('ctrl+q')          # creates actions 'edit' section         undo_action = qaction('undo', self)         undo_action.setshortcut('ctrl+z')          redo_action = qaction('redo', self)         redo_action.setshortcut('ctrl+y')          # creates actions "help" section         doc_action = qaction('documentation', self)         # no shortcut needed          about_action = qaction('about', self)         # no shortcut needed  ####################################################          # adds actions menu bar under 'file'  tab         file.addaction(new_action)         file.addaction(open_action)         file.addaction(save_action)         file.addaction(save_as_action)         file.addaction(quit_action)          # adds actions menu bar under 'edit'  tab         edit.addaction(undo_action)         edit.addaction(redo_action)          # adds actions menu bar under 'help' tab         helpme.addaction(doc_action)         helpme.addaction(about_action)          # events          # sets initial window size , title         self.setwindowtitle('my menu')         self.resize(750, 500)          self.show()  ####################################################  def quit_trigger(self):     pass   def selected(self, q):     pass   app = qapplication(sys.argv) menus = menudemo() sys.exit(app.exec_())

problem:

i have menu bar displayed, , seems run fine, there 1 thing bugging me. under 'file' tab of menu, there option called 'quit'. above 'quit' option, need have sort of line break seperate option rest of other options. in tkinter simple task do, can't seem find how pyqt5. appreciated!

p.s: menu items buttons, dont yet.

addseparator method of qmenu occasion:

# ... file.addaction(save_as_action) file.addseparator() file.addaction(quit_action) # ...

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
