QCombobox of Checkboxes

问题

I have a problem and I hope that you can help me. I want to create a Combobox of Checkboxes on Qt Creator. This is my code

mod = new QStandardItemModel(1,0);
QStandardItem *item;
item = new QStandardItem("First");
item->setCheckable(true);
mod->setItem(0,item);
item = new QStandardItem("Second");
item->setCheckable(true);
mod->setItem(1,item);
ui->comboBox->setModel(mod);

I built this code but in combobox are no checkboxees. Someone on the web told me that I have to use the event. Can you help me?

回答1:

you only have to set an initial checkState additonally

item->setCheckState(Qt::CheckState state);

e.g.

item->setCheckState(0);
