c++ - Connection between Qt and Code in Visual Studio -


i have installed qt on visual studio 2013 , have question: how can make connection between button , code visual?. need make simple menu aplication.

i don't specifying connections in ui file using gui (where can select signal , slot , rest of work you). gui buggy. recommend calling connect method in code. example, in main window constructor or special method sets connections (and is, in turn, called constructor):

connect(ui->button, signal(clicked(void)), /* or other object */, slot(buttonclicked(void));

if use qt 5 , not qt 4, recommend new connection syntax. it's both easier debug (you're compile-time error instead of runtime error if connection can't made), and, suspect, might result in faster / smaller code:

connect(ui->button, &qpushbutton::clicked, /* or other object */, &cmainwindow::buttonclicked);

the latter method has additional benefit of autocompletion working in visual studio , not in qt creator.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
