qt - QPushButton focus -

i have pushbutton background image gets changed regularly according packets ui receives serial. when user clicks button, becomes red borders.

pb_jack1up  ->setstylesheet("qpushbutton {border-image: url(:/arrowkey/up_default.jpg);  } qpushbutton:focus {border-width: 1px;border-style: solid; border-radius: 4px;}"); 

now, want give button effects, make user understand button clicked. make button go inside when clicked, , when user releases button border shall no longer set anymore. however, in case button border remains. cannot set style sheet pressed , released slots, because background image depends on receive serial.

could me please?

you can use:

qpushbutton          { ... } qpushbutton:disabled { ...  } qpushbutton:pressed  { ... } qpushbutton:focus    { ... } qpushbutton:hover    { ...   }
