c++ - Forcing a recalcuation of Qt Stylesheet appears to do nothing -


using stylesheets i'm trying change window's style, including children.

all children named, using setobjectname , stylesheet uses same name change style of named widgets (as few extract never needs changed). i'm recalculating stylesheet first inserting values std::map, mapping names, such qwidget#hello!hover, set of key-value pairs, such background-color #0f0f0f. i.e. ["qwidget#hello!hover"]["background-color"] = "#0f0f0f", 1 entry.

when stylesheet map changed recalculate entire stylesheet , set using setstylesheet on main widget, adding /* */ @ top (supposedly, should force recalculation of stylesheet). however, doesn't appear @ all.

doing this, in constructor of main widget works fine, doesn't once it's been set @ first.

the stylesheet calculate valid , entries ordered in way expect to, widgets have expected names , since works first time i'm setting it, suspect problem either new stylesheet has no effect or has no effect on children.

i'm using qt 5.4 (old shitty crap software that's developed qt3) on windows 10.

how can fix this?

i fixed problem setting stylesheet on children of main widget. after calculating new stylesheet, , storing in qstring, named stylesheet, used:

qlist<qwidget*> children = findchildren<qwidget*>();  (qlist<qwidget*>::iterator child = children.begin(); child != children.end(); ++child);     (*child)->setstylesheet(stylesheet);

and worked charm. changes rare , there aren't whole lot of stuff in window, cost of doing isn't big of deal -- i'm sure can done more effeciently.

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
