QSqlRelationalDelegate Draw a clickable QToolButton

[wysota]

Your code doesn't make sense. Why do you create a tool button in every repaint of the cell? If you want to draw a tool button, then use QStyle::drawComplexControl() with CC_ToolButton as its parameter.

What are you trying to do exactly?

i have 11 cell on my table only 9 ist editable from model .... and one cell wo is not editable.. i must make a link (connect) to to edit moore field in a form.... and a symple doupleclick is not inaf ..... or i draw a button inside or a qpixmap buttonstyle to append event ... wo people understand to click ,,, && open other dialog.....

I search drawComplexControl i found only a small piece code.... on

http://www.koders.com/cpp/fidE11AA04...ComplexControl

How i can integrate to my model .....?
is this a pain event from QSqlRelationalDelegate subclass?

void QTitleBar::paintEvent(QPaintEvent *)

Why don't you just create an editor widget and assign it to the delegate for appropriate fields?

An createEditor subclass .... is only to editable flag? or i write mistake?

i can test to emulate a Qt::ItemIsEditable; and return true (on set data ) to column 0 (zero) in this place wo i wand click action ....

QWidget *BaseDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
     if (index.column() == 11 || index.column() == 7 ) {
        QDateTimeEdit *editor = new QDateTimeEdit(parent);
        editor->setDisplayFormat("dd.MM.yyyy");
        editor->setCalendarPopup(true);
        return editor;
     }  else {
        return QItemDelegate::createEditor(parent, option, index);
    }
}
void BaseDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
    if (index.column() == 11 || index.column() == 7 ) {
        QString dateuser = index.model()->data(index, Qt::DisplayRole).toString();
        QDateTimeEdit *editorrun = qobject_cast<QDateTimeEdit *>(editor);
         if (editorrun) {
            editorrun->setDate(QDate::fromString(index.model()->data(index, Qt::EditRole).toString(), "dd.MM.yyyy")); 
         }
    }  else {

Yes and no. Under normal circumstances it is only for editable items but you can also open something what is called a persistent editor. It is an editor that is always active, regardless of the item focus.

i can test to emulate a Qt::ItemIsEditable; and return true (on set data ) to column 0 (zero) in this place wo i wand click action ....

I don't understand what you mean.

note: code paste from gedit not from scite \n\n buggi scite?

Again, I can't understand you.

Help why i become "Advanced user" ??

Because you post too much
