QListview margin transparent

sunil.nair

Hi,

I am setting the stylesheet of a QListView by
listView->setStylesheet(QListView {
color:blue;
background:red;
border-top:1px solid gray;
margin:2px;})

WHen I set a margin, I see a 2px with around the list which is white in color. SOmehow I cannot control the color of this margin around the listview. How can I control that? I want to make the margin transparent.

Hi,

Can you show a complete QListView initialization so that other can try to reproduce your use case with the same code ?

    QListView *listView = new QListView(this);
    listView->setStyleSheet("QListView {\
                                color: rgb(72,72,72);\
                                background-color: rgb(228,228,228);\
                                border-top: 0px solid rgb(40,40,40); min-width:133px;\
                                margin:0px;\
                             }\
                             QListView::item:hover {\
                                color:rgb(228,228,228);\
                                background-color: rgb(72,72,72);\
                             }\
                             ");
     setView(listView);

On what are you setting that view ?

sunil.nair

@SGaist I apologise for the delayed response. I am setting this on a combobox. It works correctly. The only problem is that the popup keeps jumping every time I click on the combobox.

SGaist

Can you add your combo box initialization to the code ? That way it can be tested the same as you have on your machine.

By the way, which OS/Qt version are you running ?

sunil.nair

@SGaist Sorry for the delay. I am working on Mac. Qt 5.5. My problem has changed a little.
This is my complete code. Everything works correctly. Except that the popup of the comboBox keeps jumping every time I click on the drop down.

IvySnapshotComboBox::IvySnapshotComboBox(QWidget *parent):
    QComboBox(parent)
{

    //Do not insert item to combobox on pressing enter
    setInsertPolicy(QComboBox::NoInsert);
    //Set its size policy to [fixed,fixed]
    setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed);
    //Set height and width
    setFixedSize(133,36);
 
    QStyledItemDelegate* itemDelegate = new QStyledItemDelegate();
    setItemDelegate(itemDelegate);

    setStyleSheet("QComboBox {\
                  border: 0px solid rgb(228,228,228);\
                      border-radius: 3px;\
                  font-family: \"Helvetica Neue Med\";\
                  font-size: 11px;padding-left:31px;margin-top:1px;\
              }\
              \
              QComboBox:!editable {\
                  color: rgb(72,72,72);\
                  background:  rgb(228,228,228);\
              }\
              \
              QComboBox::drop-down {\
                  background:  rgb(228,228,228);border-radius: 3px;\
                  width: 40px;\
              }\
              \
              QComboBox::down-arrow {\
                  subcontrol-position: left;\
                  image: url(:/images/Arrow_on.png);\
              }\
              QComboBox::down-arrow:on { \
                  image: url(:/images/Arrow_on.png);\
              }QComboBox QListView{ color:red; background:yellow;margin:5px;}\
              ");
      QListView *listView = new QListView(this);
      listView->setStyleSheet("QListView {\
                                  color: rgb(72,72,72);margin:0px;border-radius:3px;\
                                  selection-background-color: rgb(72,72,72);\

                               }\
                            ");
    setView(listView);
    QStringList list;
    list << "Shirt" << "Shoe";
    addItems(list);
}
void IvySnapshotComboBox::showPopup()
{
    QComboBox::showPopup();
    QWidget *popup = this->findChild<QFrame*>();
    popup->move(popup->x()+8,popup->y()-(maxElements-i)*this->height()-2);
}

SGaist

Jumping ? Likely because you are moving it by hand. Why are you moving it by hand ?

sunil.nair

@SGaist Moving it by hand? Do you mean the show Popup function(). Even if I don't use that, the position is inconsistent with this code.

SGaist

Can you check with a more recent version of Qt ?

I can't reproduce your problem, I don't know what i should be. But if I remove the showPopup method it shows the combobox at the right place for OS X.
