Update QTreeWidget during runtime

I'm new to Qt and I was trying to update the data of a QTreeWidget. The QTreeWidget is created by Qt Creator (using drag and drop). The QTreeWidget I created is as below.

1
    a   A  
    b   A
    c   C
2
    x   X
    y   Y
    z   Z

I need to update the 2nd column of 2nd row A to B in run-time using code.

b   A

to 

b   B

Anyone knows how to update the value? As I created the QTreeWidget in ui designer. The Widget name is treeWidget.

Solution

  • Based on the QTreeWidget and QTreeWidgetItem documentation, you can do it as follows:

    treeWidget->topLevelItem(0)->child(1)->setText(1, "B")
