@mrjj
actually I am trying to display certain set of rows in table based on key entered and when I enter new key in textedit and push button it should display the rows related to entered key

Hehe so that is very different from clearing the view.

You might want to use a proxy model to do the filtering.

Hi,
@mrjj ,

Thanks for your suggestion, I tried using proxy model.
With this I can filter fields in same table view.

But, I am trying to display the filtered data in different table view .
i.e one main table view will be showing all the entries, and once I enter the key, the filtered data is displayed in other table view.

So while doing the same I am able to filter data and display in separate table view, but when I am entering new key and pushing button, the table view is displaying the new filtered data along with previous list.

I.e my need is to refresh the table view every time I enter key and push the button and display new filtered data.

Thanks,
Sushmita

Hi,

Can you show the code related to the model and filtering ?

@SGaist

Sorry, but it is some internal code , and not supposed to share.

I have created two table views using QAbstractTableModel.
In 1st table view all entries and filtering data based on key entered and inserting the rows into 2nd model(table view).

SGaist

Why a custom table model ? Since you are using a QSortFilterProxyModel, just assign that one to the view showing the filtered data. There's no need for that second model.

@SGaist said in PyQt reset tabelView:

QSortFilterProxyModel

I am not using QSortFilterProxyModel

SGaist

Sorry, I misunderstood your answer to @mrjj.

In any case, that would likely be the solution. You have a view on your complete data, then on the filtered view, you put the QSortFilterProxyModel as model on top of your main data. That way you don't have to manually add/remove stuff from a secondary model that would duplicate the data already available.

@SGaist

Ok. Thanks .
I thought of trying without using QSortFilterProxyModel
I will try .

Hi,

Can we use QSortFilterProxyModel with QAbstractTableModel?
Cause the example which was suggested proxy model I referred is using QStandardItemModel.

But in my application I am usign QAbstractTableModel for data model.

Thanks,

No problem with that.
