[Solved]QSortFilterProxyModel dont find in the "folder"

Ruzik

Hellow!
I use this code:
@ searchModel.setSourceModel(itemModel);
connect(searchLineEdit, SIGNAL(textChanged(const QString&)), this, SLOT(findInModel(const QString&)));@
@void RizekFaster::findInModel(const QString& str)
{
if(str.isEmpty())
{
dataTreeView->setModel(itemModel);
return;
}
searchModel.setFilterWildcard(str);
dataTreeView->setModel(&searchModel);
}@
But my sort model dont find items in "folders", it find only items which have not parents
For example:
This is my program with all item in my item model
!http://s1.hostingkartinok.com/uploads/images/2012/02/28e3848a1f4e041e2af0461851dde433.jpg(1)!
And it is my program with QSortFilterProxyModel
!http://s1.hostingkartinok.com/uploads/images/2012/02/58a21d47c6552e76ea79e8b186f40874.jpg(2)!
How can i do that my sort model find all items?
And other question:
How can i do that my QSortFilterProxyModel find items in all columns simultaneously?
In advance many thank for your help!

Hi,

Did you try

@
QSortFilterProxyModel::setFilterKeyColumn(int)
@

?

filterKeyColumn : int

This property holds the column where the key used to filter the contents of the source model is read from.
The default value is 0. If the value is -1, the keys will be read from all columns.

By default it is only searching in the column 0

@
void RizekFaster::findInModel(const QString& str)
{
if(str.isEmpty())
{
dataTreeView->setModel(itemModel);
return;
}
searchModel.setFilterWildcard(str);
searchModel.setFilterKeyColumn(-1); /this solves/
dataTreeView->setModel(&searchModel);
}

I wrote a proxy you might use as inspiration. Depending on the size of your model, it might need serious performance enhancements, but it is a start. Check "this":http://developer.qt.nokia.com/forums/viewthread/7782 topic for details.
