I have a QTableView
showing rows of a database table. In this table I have a column called data type and I have icon images for each type. How can I add these icons in front of each data type?
Here's a part of my code as requested by justanothercoder.
QString msgQueryString = "select MESSAGE_ID, DATA_TYPE from SER_MESSAGES where MESSAGE_ID > 500 ";
serendibMsgTableModel->setQuery(msgQueryString, *database);
serendibMsgTableModel->setHeaderData(0, Qt::Horizontal, tr("Message ID"));
serendibMsgTableModel->setHeaderData(1, Qt::Horizontal, tr("Data Type"));
serendibMsgProxyModel->setSourceModel(serendibMsgTableModel);
serendibMsgView->setModel(serendibMsgProxyModel);
"serendibMsgTableModel" is a QSqlQueryModel
and "serendibMsgProxyModel" is a customized QSortFilterProxyModel
. "serendibMsgView" is the QTableView
I need the icons to be displayed, in the Data Type column.
Hope this helps for your answer.
Set the DecorationRole of your items to the QPixmap you want and it should work.
edit:
I guess that the icon depends on the value in the data type column.
int rowCount = serendibMsgTableModel->rowCount();
for(int row = 0; row < rowCount; row++)
{
QModelIndex index = serendibMsgTableModel->index(row, 1);
QVariant value = serendibMsgTableModel->data(index);
static QPixmap s_invalidIcon(PATH_TO_INVALID_ICON);
static QPixmap s_type1Icon(PATH_TO_TYPE1_ICON);
static QPixmap s_type2Icon(PATH_TO_TYPE2_ICON);
QPixmap icon(s_invalidIcon);
if(value.toString() == "type1")
{
icon = s_type1Icon;
}
else if(value.toString() == "type2")
{
icon = s_type2Icon;
}
serendibMsgTableModel->setData(index, icon, Qt::DecorationRole);
}
Something like this should work. Set the values before setModel.
I haven't tested it, but I think you should get the idea from this.
