QTreeWidget setCurrentItem difference height with the same setStyleSheet

[norobro]

That's pretty strange. I tried setting the style sheet in the MainWindow ctor and it seems to work:

ui->treeWidget->setStyleSheet("::item {   margin-top:2;    margin-bottom:2; min-height:20;} "
                              "::item:selected:!active   {  background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, "
                                 "stop: 0 rgb(255,211,159), stop: 0.4 rgb(254,180,72), stop: 1 rgb(254,222,119));}"
                              "::item:selected:active  {  background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, "
                                 "stop: 0 rgb(66,180,255),   stop: 1 rgb(0,152,255)); }"
                              "::item:hover {  background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, "
                                 "stop: 0 rgb(247,235,224), stop: 1 rgb(255,211,159));}");

ui->treeWidget->setStyleSheet("::item {   margin-top:2;    margin-bottom:2; min-height:20;} "
                              "::item:selected:!active   {  background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, "
                                 "stop: 0 rgb(255,211,159), stop: 0.4 rgb(254,180,72), stop: 1 rgb(254,222,119));}"
                              "::item:selected:active  {  background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, "
                                 "stop: 0 rgb(66,180,255),   stop: 1 rgb(0,152,255)); }"
                              "::item:hover {  background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, "
                                 "stop: 0 rgb(247,235,224), stop: 1 rgb(255,211,159));}");

Didn't get any warnings but maybe there is a problem parsing your css file.

Edit: I quit reading and tried your code before getting to case 3.
