Error message when calling function

gabor53

Hi,
I have the addNewImage function with the following code:
imagedelegate.h:

 void addNewImage(QString imageFile);

imagedelegate.cpp:

void ImageDelegate::setModelData(QWidget* editor, QAbstractItemModel* model, const QModelIndex& index) const {
  ImagePickButton* imgPick = qobject_cast<ImagePickButton*>(editor);
  Q_ASSERT(imgPick);

  if(imgPick->selectedFile().isEmpty()) {
    model->setData(index, QVariant(), Qt::UserRole);
    model->setData(index, QVariant(), Qt::DecorationRole);
  } else {
    model->setData(index, imgPick->selectedFile(), Qt::UserRole);
    model->setData(index, QIcon(imgPick->selectedFile()), Qt::DecorationRole);

    addNewImage (imageFile);//Not working
  }
}

void ImageDelegate::updateEditorGeometry(QWidget* editor, const QStyleOptionViewItem& option, const QModelIndex& index) const {
  Q_UNUSED(index);
  editor->setGeometry(option.rect);
}

void ImageDelegate::addNewImage(QString imageFile) {
  qDebug() << "Entered addNewImage";
}

It gives me the following error message:
C:\Programming\Projects\Folkfriends_bzr\trunk\imagedelegate.cpp:30: error: passing 'const ImageDelegate' as 'this' argument discards qualifiers [-fpermissive]
addNewImage (imageFile);//Not working
^
What is incorrect?
Thank you for your help.

Hi @gabor53

you cannot call the non-const function addNewImage in the const function setModelData. So you have to remove const from setModelData or add const to addNewImage.
