qt - QProgressBar as semi-transparent overlay -


i have been pulling out hair trying figure out how this. tried using stylesheets, no avail. on #qt said got work, when adapted code, widgets go transparent, unfortunately not qprogressbar

#include <qapplication> #include <qprogressbar>  int main(int argc, char *argv[]) {     qapplication a(argc, argv);     qwidget *widget = new qwidget();     qprogressbar *progress = new qprogressbar(widget);      qpalette palette(widget->palette());     palette.setcolor(widget->backgroundrole(), qt::green);     widget->setautofillbackground(true);     widget->setpalette(palette);      qpalette palette1(progress->palette());     palette1.setcolor(progress->backgroundrole(), qt::transparent);     progress->setautofillbackground(true);     progress->setpalette(palette1);      widget->show();     return a.exec(); }

just in case wondering why want this; trying have overlay icon of deck of cards, grab, shrinks. want transparently on icon in order save space.

any ideas?

i don't know if have special reason not stylesheets, or if couldn't work stylesheets, here solution transparency problem using stylesheets:

progress->setstylesheet("qprogressbar{"                            "border: 1px solid transparent;"                            "text-align: center;"                            "color:rgba(0,0,0,100);"                            "border-radius: 5px;"                            "background-color: qlineargradient(spread:pad, x1:0, y1:0, x2:1, y2:1, stop:0 rgba(182, 182, 182, 100), stop:1 rgba(209, 209, 209, 100));"                                "}"                            "qprogressbar::chunk{"                            "background-color: rgba(0,255,0,100);"                            "}");

you can adjust own liking.
