c++ - Qt5: How to hide or remove a QMenu from the QMenuBar? -

-

i using qt5 on windows7 platform:
qt creator version is: v3.3.2.
qt version 5.5.1 , mingw 32bit.

currently, in menu bar have:

configuration - reports - help

i searched , found possible answer: not possible hide qmenu object qmenu::setvisible()?, it didn't work...

so, trying remove menu using: 

ui->menuhelp->setvisible(false);

and: 

ui->menuhelp->menuaction()->setvisible(false);

unfortunatelly, both failed hide/remove help menu...

please, there other way it?

[code]: 

mainwindow::mainwindow(qwidget * parent) :     qmainwindow(parent),     ui(new ui::mainwindow) {     ui->setupui(this);     this->setwindowflags(this->windowflags() & ~qt::windowmaximizebuttonhint);     if(!server.listen(qhostaddress("192.168.1.2"), 8001))         return;     if(true) // testing...        ui->menuhelp->menuaction()->setvisible(false); }

just test, i've added 3 menus menubar.
tried this: 

ui->menu3->menuaction()->setvisible(false);

and worked expected - hides menu3. problem somewhere else.

the code ui->menuhelp->setvisible(false); hides menu, not action on menubar. example when click on action on menubar menu becomes visible. can hide line of code. when call directly constructor menu still invisible, code nothing.

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
