How to find an index of clicked tab in QTabWidget in Python QT? -


i developing simple text editor has mutlitabs. want implement rightclick menu rename clicked (not current) tab of qtabwidget instance. have find index of clicked tab. how can this?

from pyqt4.qtcore import * pyqt4.qtgui import *  class myapplication(...):     ...      def contextmenuevent(self, event):         tabindex = ... # <- should type here?          menu = qmenu(self)          renameaction = menu.addaction("rename")          action = menu.exec_(self.maptoglobal(event.pos()))          if action == renameaction:             self.renametabslot(tabindex)       def renametabslot(self, tabindex):         ...

you need check clicked position (i.e. event.pos ()) against tab regions manually. python bit rusty, here's c++ code instead. assuming tabwidget called mytabwidget:

int tabindex = -1; {   qtabbar* tabbar = mytabwidget->tabbar ();    qpoint globalpos   =  ->maptoglobal   (event->pos ());   qpoint posintabbar = tabbar->mapfromglobal (globalpos);    (int i=0; i<tabbar->count (); ++i)   {     if (tabbar->tabrect (i).contains (posintabbar))     {       tabindex = i;       break;     }   } }  if (tabindex < 0) {   // no tab hit...   return; }

i didn't compile&run this, idea should clear. note maptoglobal , mapfromglobal calls transform given event's position tab-bars native coordinates. hope did right.

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; } ...

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
