apply change to filtered rows is it possible?

[jaafari]

no problem bro

i just need some help on how combobox apply change to those filtered rows maybe i should write something like this:

void EditDlvrDialog::on_myFirstComboBox_somethingChanged(something)
{
    something
    something
}

void EditDlvrDialog::on_myFirstComboBox_somethingChanged(something)
{
    something
    something
}

Well, you take the value from the combobox and using that value you update your model. Do you know how to update values from your model?

[jaafari]

no bro i am sorry i don't know


can you tell me how

[wysota]

You use the QAbstractItemModel::setData() method. In general if you want to use models, you should read about them first.

[jaafari]

and how to use QAbstractItemModel::setData() ?

[yeye_olive]

and how to use QAbstractItemModel::setData() ?

Easy:

1. you stop being lazy;
2. you go read the documentation as you were already advised to;
3. you try to solve your problem;
4. you come back and explain the approaches you tried, and ask specific questions.

Does that sound reasonable to you, or would you rather have other people do for free the work you are paid for?

There is documentation in English. This forum is English. If you can't understand English documentation, how are you going to understand my English explanation?

give me a example pravite and i am ready to pay for it.. just tell me how much that will cust?

[wysota]

I can give you an example for free.

model.setData(model.index(0, 0), 7, Qt::EditRole); // sets 7 into default role of item (0, 0)

model.setData(model.index(0, 0), 7, Qt::EditRole); // sets 7 into default role of item (0, 0)

[jaafari]

and what about combobox:

void myEditDialog::on_myFirstComboBox_currentIndexChanged(int index)
{
 
}

void myEditDialog::on_myFirstComboBox_currentIndexChanged(int index)
{
   
}

To copy to clipboard, switch view to plain text mode 

should i do it like this?

[wysota]

What about it?

[jaafari]

i mean should i use it in this way?

void myEditDialog::on_myFirstComboBox_currentIndexChanged(int index)
    {
     model.setData(model.index(0, 0), 7, Qt::EditRole); // sets 7 into default role of item (0, 0)
    }

void myEditDialog::on_myFirstComboBox_currentIndexChanged(int index)
    {
     model.setData(model.index(0, 0), 7, Qt::EditRole); // sets 7 into default role of item (0, 0)
    }

[d_stranz]

So every time someone selects a different item from the combo box, you want to store the value 7 into item( 0, 0 )? Why?

Why don't you try to explain what you really want to do when someone changes the combo box selection?

[wysota]

Call it on your model passing the index, value and role in the model you wish to change (e.g. Qt::EditRole).
