[SOLVED] Searching a string in a QtableView or QStandardItemModel

amban

Hi All,
I want to search for a string in my Qtableview - What is the best way to way that ? Currently i do the simple C++ string compare way which is probably an incorrect answer.

Thanks

Hi,

you can ask for the value of the cell a, convert it to QString and compare it.
What else do you want to do?

Hi,
Actually i wanted to do it using QSortFilterProxyModel. Kindly rectify what is wrong :

@QString input = findstring->text().trimmed();
QSortFilterProxyModel proxy;
proxy.setSourceModel(mytablemodel);
proxy.setFilterFixedString(input);

 int num_rows = mytablemodel->rowCount();
 int num_cols = mytablemodel->columnCount();

 QModelIndex matchingIndex = proxy.mapFromSource(proxy.index(num_rows,num_cols));
 if(matchingIndex.isValid())
 {
     QMessageBox::information(this, "Find", "Found");
 }
 else
 {
     QMessageBox::information(this, "Find", "Not Found");
 }

@

I am setting the index incorrectly i guess. How to browse the entire table ?

I truely appreciate your help.

Hi All,
It was a minor mistake on my side instead of :
@QModelIndex matchingIndex = proxy.mapFromSource(proxy.index(num_rows,num_cols))@

it must be....
@QModelIndex matchingIndex = proxy.mapToSource(proxy.index(num_rows,0))@

Thanks

Hey amban did you have more code to get this to work? Becase I am trying to do the same thing but anything I type in, if its in the table or not, always comes up as Not Found.
