[SOLVED] Checkboxes in QListWidget appear as locked

Thegreger

Hi everybody,

I'm quite new to Qt, with a few months of experience.

I'm currently working with a project that contains a QListWidget, mainly because it's an easy solution to create lists of slightly more complex widgets. I'm trying to give each new list item a checkbox. In my current code, this is done by:

@ListFrame *frame1 = new ListFrame(this);
QListWidgetItem *item = new QListWidgetItem();
item->setCheckState(Qt::Checked);
item->setFlags(item->flags() | Qt::ItemIsUserCheckable);

ui->listWidget->addItem(item);
ui->listWidget->setItemWidget(item,frame1);@

My ListFrame class is simply a frame with a number of labels in it.
If I omit the "Qt::ItemIsUserCheckable" flag, the checkbox in my list is greyed out. With the flag, however, the checkbox is not greyed out, but it's still behaving as though it were disabled! I've tried clicking the frame that is my item, the labels that it contains, or the checkbox itself, and it never changes state. Note that this problem persists even if I use a standard class such as QLabel instead of my ListFrame.

Have I misunderstood something? According to all other info I've found, it should be enough to add the flag ItemIsUserCheckable and set a checked or unchecked state.

Thanks for any help!

Hi and welcome to the forums.
Make sure you keep the default item flags when you set checkable

  QListWidgetItem* item = new QListWidgetItem("myitem", ui->listWidget);
    item->setFlags(item->flags() | Qt::ItemIsUserCheckable); // set the checkable flag
    item->setCheckState(Qt::Unchecked); // also initialize check state

Firstly, Thanks for the reply.
sorry for not mentioning the problem clearly.

I have an QListWidgetItem and need to make the text editable. so used QLineEdit as itemwidget.

QLineEdit *lineEditStructureName = new QLineEdit();
lineEditStructureName->setText(structureName);
lineEditStructureName->setFocusPolicy(Qt::ClickFocus);
//listWidgetItem->setSizeHint (lineEditStructureName->sizeHint ());
this->ui->listWidgetStructures->setItemWidget (listWidgetItem, lineEditStructureName);

Now the problem is Not getting accessed. as the links description its kind of locked.
Is there anything I'm doing wrong ?

@sateesh Set Qt::ItemIsEditable flag on your item.
