Sub classing QListWidgetItem

[Majdi]

Hello,

I have small problem and I think its the last one to finish this project. I have I want to create Table view that contain items ( QListWidgetItem). Each item should contain name, image and pointer to hold object from type ( QSqlQueryModel).

I have to problem by item name and image. The only problem is to add to that Item a pointer can hold QSqlQueryModelobject. I try to subclass QListWidgetItemand add the pointer but did not work

can anyone help me in this ?
thanks

Why don't you use the QSqlQueryModel with QListView?

I don't want to used QListView because I'm not good with Model Based , But this is not the problem.

I create QListWidget, and I use it to hold Items. Each Item has name and icon. Now I want the item to hold QSqlQueryModel .

This list will be like history of all SQL quires, so when the user do a query it will be saved in that list as QSqlQueryModel object, When the user click on the icon , the query result will be read loaded in the box of result. so each time the user choose query from history , I just need to take the QSqlQueryModel object which saved in the items of the list and pass it to the table view which show the result.

because of that i want the item of the list which is from type QListWidgetItem to have ability to carry object from type QSqlQueryModel , and this is my problem

A simpler approach to your problem would be as follows -
For the listWidgetItem, use setData to store the result in your defined role, say RESULT_ROLE.
Now use a custom delegate and override the drawDisplay as follows -

MyDelegate::drawDisplay(......)
{
      QString result = text; // text is the argument string to draw
      if(option.state & Qt::Selected)    // if item is selected...
             result = index.data(RESULT_ROLE);
 
      QItemDelegate::drawDisplay(result....); // use result instead of text
}

MyDelegate::drawDisplay(......)
{
      QString result = text; // text is the argument string to draw
      if(option.state & Qt::Selected)    // if item is selected...
             result = index.data(RESULT_ROLE);

      QItemDelegate::drawDisplay(result....); // use result instead of text
}

To copy to clipboard, switch view to plain text mode 

Hope this works for you
