Treewidgetitems list

[sam123]

Hello,

I want to show my product list in QTreeWidget from my sql database. I am trying with QList<QTreeWidgetItems * >items, but still not able to get output.
secondly, I have developed GUI for desplaying my all product details, after clicking on my device name from TreeWidget my all detail data should be shown in my GUI.

looking for your solutions..

Thanks in advance

Looks like you forgot to post the code that processes your SQL query and creates tree widget items.

Thanks for reply

here are some code I have used for desplaying data in Treewidget from database.

QSqlquery query;
   query.prepare("select DeviceName from Devices" );
 
      if(query.exec())
         {
             ui->treeWidget_Device->setColumnCount(1);
 
             QList<QTreeWidgetItem *> items;
 
             for (int i = 0;  i < 10; ++i)          // here I have confusion about list numbers. y list is verx big and will be added more
 
             item.append(new QTreeWidgetItem((QTreeWidget*)0, QString("item: %1").arg(i)));        //this is an example with simple string but I want to show  
                                                                                                                                         my query in here
             ui->treeWidget_Device->insertTopLevelItems(0, items);                 
 
        }

QSqlquery query;
   query.prepare("select DeviceName from Devices" );

      if(query.exec())
         {
             ui->treeWidget_Device->setColumnCount(1);

             QList<QTreeWidgetItem *> items;

             for (int i = 0;  i < 10; ++i)          // here I have confusion about list numbers. y list is verx big and will be added more

             item.append(new QTreeWidgetItem((QTreeWidget*)0, QString("item: %1").arg(i)));        //this is an example with simple string but I want to show  
                                                                                                                                         my query in here
             ui->treeWidget_Device->insertTopLevelItems(0, items);                 

        }

hope these code will be enough to understand my difficulty...

looking for your advice..

Thanks

You need to iterate over the query, the documentation has an example for that.

Independent of that, do your other tree widget items appear? I.e. the ones with "item: number"?

Yes the one with items :numbers appears in my treewidget, but Its just an example i have given to show my code. I want to display data list from database

for example I have devices list in database table such as,

1. A
2. B
3. C
4. D
.
.
.

I want to display the above list in QTreewidget..

Thanks

Then you need to iterate over the query instead of over a numerical range.

You can post that code if you don't get it to work.

Not really useful to post code that works but isn't what you are actually doing
