c++ - QAbstractItemDelegate, editorEvent, CE_PushButton and item selection -


i'm having problem selection of delegated item represents 2 text lines , ce_pushbutton. want have row selected clicking button too. here paint function code:

void columntwolinesdelegate::paint(    qpainter *painter,    const qstyleoptionviewitem &option,    const qmodelindex &index ) const {    if (!index.isvalid())        return;     if (option.state & qstyle::state_selected)    {       painter->setpen(qpen(qt::white));        if (option.state & qstyle::state_active)       {          painter->setbrush(qbrush(qpalette().highlight()));       }       else       {          painter->setbrush(qbrush(qpalette().color(qpalette::inactive, qpalette::highlight)));       }        painter->drawrect(option.rect);    }    else    {       painter->setpen(qpen(qt::black));    }     qapplication::style()->drawprimitive(qstyle::pe_panelitemviewitem, &option, painter, 0);     // ...it draws 2 text lines.     painter->restore();     qrect tbuttonrect;    tbuttonrect.setx(option.rect.width() - khorizzontalmarginsize);    tbuttonrect.sety(option.rect.y() + (option.rect.height() / 2 - kbuttonsize / 2));    tbuttonrect.setwidth(kbuttonsize);    tbuttonrect.setheight(kbuttonsize);     qstyleoptionbutton tbutton;     if (index.model()->data(index.model()->index(index.row(), 5)).toint() == 1)    {       tbutton.icon = marchive;    }    else    {       tbutton.icon = mreactive;    }     tbutton.iconsize = qsize(kbuttonsize - 2, kbuttonsize - 2);    tbutton.rect = tbuttonrect;     tbutton.features |= qstyleoptionbutton::flat;     if (mcurrentrow == index.row())    {       tbutton.state = qstyle::state_sunken | qstyle::state_enabled;    }    else    {       tbutton.state = qstyle::state_raised | qstyle::state_enabled;    }     qapplication::style()->drawcontrol(qstyle::ce_pushbutton, &tbutton, painter); }

and editorevent function code:

bool columntwolinesdelegate::editorevent(    qevent *event,    qabstractitemmodel *model,    const qstyleoptionviewitem &option,    const qmodelindex &index) {    q_unused(model);     if (event->type() != qevent::mousebuttonpress       && event->type() != qevent::mousebuttonrelease)    {       return true;    }     // rect represents pushbutton    qrect tbuttonrect;    tbuttonrect.setx(option.rect.width() - khorizzontalmarginsize);    tbuttonrect.sety(option.rect.y() + (option.rect.height() / 2 - kbuttonsize / 2));    tbuttonrect.setwidth(kbuttonsize);    tbuttonrect.setheight(kbuttonsize);     qmouseevent* mouseevent = static_cast<qmouseevent*>(event);     // if mouse position outside button rect/button area use state_raised style    if (!tbuttonrect.contains(mouseevent->pos()))    {       // allows row's selection       return false;    }     if (event->type() == qevent::mousebuttonpress)    {       mcurrentrow = index.row();    }    else if (event->type() == qevent::mousebuttonrelease)    {       mcurrentrow = -1;        // when mousebuttonrelease emit signal clicked()       emit documentrequest(index);    }     return true; }

only returning false allows row selection, i'd obtain same behavior clicking button. possible? in advance, danilo

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
