i have qt application qmainwindow has menu, toolbar , primary widget. i have menu item resize application primary widget specific size yet figure out way this. so far, closest have come this: void on_actionsetsize_triggered() { ui_.primary_widget->setminimumsize(100,200); adjustsize(); } the idea being set primary widgets minimum size target size, , ask ui "shrink fit" unfortunately, seems work sporadically @ best, increase size when needed, when want reduction in size, doesn't work :-/. note: want allow user freely resize application, when ask. for size reduce while increased need set fixed size on primary widget before calling adjustsize() . can release constraint allow user re-size henceforth. you try this: ui_.primary_widget->setfixedsize(100, 200); adjustsize(); ui_.primary_widget->setmaximumsize(qwidgetsize_max, qwidgetsize_max); do note size setting on primary widget needs valid size based on what's inside it.

i trying create website using cgi , erb, when search on web, see people saying should avoid using cgi , , use rack . i understand cgi fork lot of ruby processes, if use fastcgi , 1 persistent process created, , adopted php websites too. plus fastcgi interface create 1 object 1 request , has performance, opposed rack creates 7 objects @ once. is there specific reason should not use cgi? or false assumption , entirely ok use cgi/fastcgi? cgi, mean both interface , common programming libraries , practices around it, written in different time. has view of request handlers distinct processes connected webserver via environment variables , standard i/o streams. this state-of-the-art in day, when there not "web frameworks" , "embedded server modules" think of them today. thus... cgi tends slow again, cgi model spawns 1 new process per connection. while spawning processes per se cheap these days, heavy web app initialization — reading , parsing

i'm new lua, , i'm learning usage of table these days. tutorials know lua treats numeric indexed items , non-numeric indexed items differently, did tests myself, , today found interesting phenomenon , can't explain it: the code t = {1, 2, 3, a='a', b='b'} print(#t) gets 3 because # operator counts numeric indexed items only. tested following code t = {1, 2, 3, a='a', b='b'} print(#t) = 100,200 t[i] = end print(#t) i get 3 3 till think lua treats discontinuous items added later non-numeric indexed ones. however, after change code little bit t = {1, 2, 3, a='a', b='b'} print(#t) = 100,300 t[i] = end print(#t) i get 3 300 i'm confused phenomenon, know reason? thanks. (this phenomenon can reproduced @ http://www.lua.org/cgi-bin/demo ) update: i tried code t = {1, 2, 3, a='a', b='b'} print(#t) = 100,300 t[i] = print("add", i, #t) end = 100,300

background: developing facebook app using php laravel framework & mysql database. i have setup gitlab on our development server , created repository on team has been added , committing & pushing code. what is, when push code particular branch on gitlab (for example master) available @ /var/www/productname can test within facebook canvas (certain things happen there can't tested on local machine). however, don't want hook copy files on every time push happens on master, files modified. can out such hook? thank you. use rsync rather cp operation. diff checking automatically. way post-commit hook doesn't become needlessly complicated.

when application needs upload many large files, better solution: 1) doing on separate process ( i.e. remote service )? 2) using separate thread (or asynctask )? is there clear , definite answer this? the application, way, uploading things time - small chunks of data. every , needs send large files, want separate mechanism 1 using. (btw small chunks using single task thread works great) i understand asynctask one-time operations , threads better many-operations it better use asynctask asynstask nothing thread since uploading multiple files, multithreading necessary avoid exception

i have graph of objects support nscoding . , have separate class takes care of serialization itself, ie. detects changes in object graph , uses nskeyedarchiver save file. i’m happy design, i’m not sure how watch changes in object graph. 1 general solution thought of add version property each object gets incremented each change: - (void) setfoo: (id) newfoo { _foo = newfoo; self.version++; } when object in graph references other objects, observes version (using kvo) , if changes, change propagated upwards. serialization class observes version of root node. this works, managing kvo stuff cumbersome , prone errors. can think of a better solution? 1 further constraint objects know little serialization possible. should know how serialize (by implementing nscoding ), shouldn’t care more. this has common problem in serialization frameworks, right?

i have 2 bundles userbundle , xxxbundle. want after authenticating user in user bundle redirect xxxbundle. but, depending on roles (role_admin , role_user), redirect him 2 different routes (route1, route2). i added controller userbundle class securitycontroller extends controller { public function loginaction() { if ($this->get('security.context')->isgranted('role_admin')) { return $this->redirect($this->generateurl('route1')); } if ($this->get('security.context')->isgranted('role_user')) { return $this->redirect($this->generateurl('route2')); } $request = $this->getrequest(); $session = $request->getsession(); // on vérifie s'il y des erreurs d'une précédent soumission du formulaire if ($request->attributes->has(securitycontext::authentication_error)) { $error = $request->attributes->get(securitycontext::authentication_error);

this question gcc constructor, compile & link right, not run. there a.c: utest_begin() uid(a_test) { printf("a test"); return true; } utest_end(a) b.c simlar: utest_begin() uid(b_test) { printf("b test"); return true; } utest_end(b) the code object using uid() link test functions. first version add utest_begin() utest_end() enclose uid(), @ last realize utest_bgin() utest_end() isn't necessary, when change them unpredicated result. when change definition of utest_begin(), uid(), utest_end(), got different result. the basic idea come can-i-auto-collect-a-list-of-function-by-c-macro ! test 1: #define utest_begin() \ static const bool __m_en = true; \ static struct __uti *__m_uti_head = null; bool utest_item_list_add_global(struct __uti *uti); #define uid(f) \ static bool __uti_##f(void);
