Display ItemDelegate Editor always

[gast23]

Hi,

i wrote a little itemdelegate for my tableview:

#include "checkboxdelegate.h"
 
#include <QDebug>
 
CheckboxDelegate::CheckboxDelegate(QObject *parent) :
    QStyledItemDelegate(parent)
{
}
 
QWidget* CheckboxDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option,
                                        const QModelIndex &index) const {
 
    QCheckBox *editor = new QCheckBox(parent);
    return editor;
 
}
 
void CheckboxDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const {
 
    bool value = index.model()->data(index, Qt::EditRole).toBool();
 
    qDebug() << value;
 
    QCheckBox *check = static_cast<QCheckBox*>(editor);
    check->setChecked(value);
 
}
 
void CheckboxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                    const QModelIndex &index) const {
 
    QCheckBox *check = static_cast<QCheckBox*>(editor);
    model->setData(index, check->isChecked(), Qt::EditRole);
 
    qDebug() << "setModelData" << check->isChecked();
 
}
 
void CheckboxDelegate::updateEditorGeometry(QWidget *editor,
                                            const QStyleOptionViewItem &option, const QModelIndex &index) const {
 
    editor->setGeometry(option.rect);
 
}

#include "checkboxdelegate.h"

#include <QDebug>

CheckboxDelegate::CheckboxDelegate(QObject *parent) :
    QStyledItemDelegate(parent)
{
}

QWidget* CheckboxDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option,
                                        const QModelIndex &index) const {

    QCheckBox *editor = new QCheckBox(parent);
    return editor;

}

void CheckboxDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const {

    bool value = index.model()->data(index, Qt::EditRole).toBool();

    qDebug() << value;

    QCheckBox *check = static_cast<QCheckBox*>(editor);
    check->setChecked(value);

}

void CheckboxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                    const QModelIndex &index) const {

    QCheckBox *check = static_cast<QCheckBox*>(editor);
    model->setData(index, check->isChecked(), Qt::EditRole);

    qDebug() << "setModelData" << check->isChecked();

}

void CheckboxDelegate::updateEditorGeometry(QWidget *editor,
                                            const QStyleOptionViewItem &option, const QModelIndex &index) const {

    editor->setGeometry(option.rect);

}

To copy to clipboard, switch view to plain text mode 

Everything works fine. If i click on a cell the editor poups up and i'm able to edit the value.

Now i would like that the editor is always displayed (User sees always the checkbox)

It this possible?

Thanks

Try using setModelData in your delegate. This should display your object all of the time.

Sry what do you mean?'

Here is an example of doing this for a combo box. You should be able to alter this for using a check box.

void ModeDelegate::setModelData(QWidget* editor, QAbstractItemModel* model,
                               const QModelIndex& index) const
{
   QComboBox* comboBox = static_cast<QComboBox*>(editor);
   QString value = comboBox->currentText();
 
   model->setData(index, value, Qt::EditRole);
}
 
void ModeDelegate::updateEditorGeometry(QWidget* editor,
                                       const QStyleOptionViewItem& option, const QModelIndex &/* index */) const
{
   editor->setGeometry(option.rect);
}

void ModeDelegate::setModelData(QWidget* editor, QAbstractItemModel* model,
                               const QModelIndex& index) const
{
   QComboBox* comboBox = static_cast<QComboBox*>(editor);
   QString value = comboBox->currentText();

   model->setData(index, value, Qt::EditRole);
}

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

To copy to clipboard, switch view to plain text mode

Sry but i already have this:

void CheckboxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                    const QModelIndex &index) const {
 
    QCheckBox *check = static_cast<QCheckBox*>(editor);
    model->setData(index, check->isChecked(), Qt::EditRole);
 
    qDebug() << "setModelData" << check->isChecked();
 
}

void CheckboxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                    const QModelIndex &index) const {

    QCheckBox *check = static_cast<QCheckBox*>(editor);
    model->setData(index, check->isChecked(), Qt::EditRole);

    qDebug() << "setModelData" << check->isChecked();

}

To copy to clipboard, switch view to plain text mode 

The checkbox is only displayed when editing...

Can someone help me?
I would like to display checkboxes always in qtableview

I guess you need to use a persistent editor?
These need to be set in the view, not the model I think.
