QTableView Set Header Columns not working

[toadybarker]

Hi,
I am trying to build a Table View off of a SQLModel. I create the tableview when I instantiate the object, and it displays fine, but to be accurate I blow away the table and recreate it from Romote server data (a socket). After I insert the new rows/columns, I attempt to put the headers back to the way I want them in the model/View, but the Headers are right but the sizes are wrong (seems to get default sizes). Not sure what I am doing wrong here. Here some of the code I have:

This builds the original View
casparcg_Videos_Model = new QSqlTableModel( this,my_Db);
casparcg_Videos_Model->setTable("CASPARCG_ENTRIES");
casparcg_Videos_Model->select();
casparcg_Videos_Model->setHeaderData((CG_CLS_FILENAME+1),Qt::Horizontal, tr("Video File Name"));
casparcg_Videos_Model->setHeaderData((CG_CLS_TYPE+1),Qt::Horizontal,tr(" Type"));
casparcg_Videos_Model->setHeaderData((CG_CLS_SIZE+1),Qt::Horizontal,tr(" Size"));
casparcg_Videos_Model->setHeaderData((CG_CLS_CREATE_DATE+1),Qt::Horizont al,tr("Creation Date"));
casparcg_Videos_Model->setHeaderData((CG_CLS_DURATION+1),Qt::Horizontal, tr("Duration"));
casparcg_Videos_Model->setHeaderData((CG_CLS_FRAMERATE+1),Qt::Horizontal ,tr("Frame Rate"));

currentCasparWindow = new QTableView();
currentCasparWindow->setModel(casparcg_Videos_Model);
currentCasparWindow->setSelectionBehavior(QAbstractItemView::SelectRow s);
currentCasparWindow->setSelectionMode(QAbstractItemView::SingleSelecti on);
currentCasparWindow->setColumnWidth((CG_CLS_FILENAME+1),205);
currentCasparWindow->setColumnWidth((CG_CLS_TYPE+1),45);
currentCasparWindow->setColumnWidth((CG_CLS_SIZE+1),45);
currentCasparWindow->setColumnWidth((CG_CLS_CREATE_DATE+1),100);
currentCasparWindow->setColumnWidth((CG_CLS_DURATION+1),100);
currentCasparWindow->setColumnWidth((CG_CLS_FRAMERATE+1),100);
currentCasparWindow->resizeColumnsToContents(); // Attempt to change column sizes
currentCasparWindow->hideColumn(CV_VIDEO_ID_COL); // Dont Show Video ID
QHeaderView *CGheader = currentCasparWindow->horizontalHeader();
CGheader->setStretchLastSection(true);
currentCasparWindow->show();

This recreates it:
while(tcpSocket.canReadLine())
{
raw_Data = tcpSocket.readLine();
hold_String = raw_Data;
video_List= QStringList();
if (hold_String.length() > 3) //Ignore blank lines at end...
{
count++;
parse_CLS_Return(hold_String,video_List); //builds the column values...
sql = " INSERT INTO CASPARCG_ENTRIES ";
sql += "SET ID = " + QString::number(count) + ", ";
sql += " FILENAME = \"" + video_List[CG_CLS_FILENAME] + "\", ";
sql += " TYPE = \" " + video_List[CG_CLS_TYPE] + "\", ";
sql += " SIZE = " + video_List[CG_CLS_SIZE] + ", ";
sql += " CREATE_DATE = \" " + video_List[CG_CLS_CREATE_DATE] + "\", ";
sql += " DURATION = " + video_List[CG_CLS_DURATION] + ", ";
sql += " FRAMERATE = \" " + video_List[CG_CLS_FRAMERATE] + "\"";
query.prepare(sql);
ret = query.exec();
if (!ret)
{
error_DB_Message_Box(" Failure Insert CASPARCG_ENTRIES");
}
}
}
}
}
cmd_Mode="";
casparcg_Videos_Model->select();
casparcg_Videos_Model->setHeaderData((CG_CLS_FILENAME+1),Qt::Horizontal, tr("Video File Name"));
casparcg_Videos_Model->setHeaderData((CG_CLS_TYPE+1),Qt::Horizontal,tr(" Type"));
casparcg_Videos_Model->setHeaderData((CG_CLS_SIZE+1),Qt::Horizontal,tr(" Size"));
casparcg_Videos_Model->setHeaderData((CG_CLS_CREATE_DATE+1),Qt::Horizont al,tr("Creation Date"));
casparcg_Videos_Model->setHeaderData((CG_CLS_DURATION+1),Qt::Horizontal, tr("Duration"));
casparcg_Videos_Model->setHeaderData((CG_CLS_FRAMERATE+1),Qt::Horizontal ,tr("Frame Rate"));
currentCasparWindow->setModel(casparcg_Videos_Model);
currentCasparWindow->setColumnWidth((CG_CLS_FILENAME+1),205);
currentCasparWindow->setColumnWidth((CG_CLS_TYPE+1),45);
currentCasparWindow->setColumnWidth((CG_CLS_SIZE+1),45);
currentCasparWindow->setColumnWidth((CG_CLS_CREATE_DATE+1),100);
currentCasparWindow->setColumnWidth((CG_CLS_DURATION+1),100);
currentCasparWindow->setColumnWidth((CG_CLS_FRAMERATE+1),100);

NO matter what I do it does not seem to give me the right ColumnWidths. If I did not do the SetHeaders, then I would get the actual DB Column headings as well....

Any ideas would be greatly appreciated.

Set the column widths in the view by setting the section widths in the horizontalHeader()
QHeaderView::resizeSection() and friends.

Thanks - that helped. Was able to use the HeaderPtr-> setSectionResizeMode(QHeaderView::ResizeToContents ) to make everything in the columns visible. It was exactly what I think I need (for now). Removed all of the other SetColumnSizes code.
