How to QTableWidget default values on insertion?

[RawArkanis]

Hi all!

I'm trying to make some tables where some fields have a default value.
When a new record is inserted into these fields, they should be filled with their default values.

I am having difficulty doing that. I have several different tables, all inherits some methods of a base baseclass (modified QTableWidget), such as keyEvents.
In these events I use the function for inserting rows. So I could not just put the defaults after.

Is there any method that can be re-implemented to run every time a new row is inserted? Or should I do otherwise?
I thinked about... I can make a virtual method in the baseclass and call it after the row insertion, then re-implement in the child class. Is this a better way?

Sorry, for my bad english!

If needed, I can post the code here.

Thx!

As I understand you, you have a base class with a function that creates a new row with several items.
So why do you not just put the desired values there? Make a member variable where you store the default values (this variable is defined by each subclass) and use these values while create your new row.

class BaseClass{
  QList<int> defaultValues;
  void createRow() {
    // use defaultValues
  }
};
 
class Child : public BaseClass
{
  public:
    BaseClass() {
      defaultValues = //...
    }
}

class BaseClass{
  QList<int> defaultValues;
  void createRow() {
    // use defaultValues
  }
};

class Child : public BaseClass
{
  public:
    BaseClass() {
      defaultValues = //...
    }
}

Of course a private member variable with a proper setter function is nicer...
