Checked item in QTreeWidget?

[vishal.chauhan]

Hi All,

I am working on qt 4.2.2 on my MAC Tiger.
I have a project in which I am change the state of a QTreeWidgetItem when an item is checked or unchecked.

This is working fine in qt 4.2.2 but when i tried this code on qt 4.3.2 then more often the item is not get checked or unchecked when i click on the item.

I want to ask whether it is due to Qt 4.3.2 or i have to do something different to do it.

Thanks.

Hi,

I m having a QTreeWidget and inserting item in the treeWidget as follows.

QTreeWidgetItem *item = new QTreeWidgetItem(MyTreeWidget);
  item->setText(0,"My Text");
  item->setIcon(0,icon);
  item->setText(1,"--");		 
  item->setCheckState(0,Qt::Unchecked);

QTreeWidgetItem *item = new QTreeWidgetItem(MyTreeWidget);
  item->setText(0,"My Text");
  item->setIcon(0,icon);
  item->setText(1,"--");		 
  item->setCheckState(0,Qt::Unchecked);

To copy to clipboard, switch view to plain text mode 

and when I click on the item in the treeWidget on Qt 4.2.2 it is checked immediately but when i am using this code in Qt 4.3.2 then the item is not checked immediately (often) and sometime it is not even checked and also giving the look of disable treeWidget.

Try adding:

item->setFlags(item->flags()|Qt::ItemIsUserCheckable);

item->setFlags(item->flags()|Qt::ItemIsUserCheckable);

To copy to clipboard, switch view to plain text mode

Thanks for reply.

I donot know why the item is getting disable sometimes when click on item.

How do you react to check state changes? Show the slot, please.

Actually I m updating the state of the current item parent in the treeWidget and link list.

It has 4 function which i m using and its not possible to post them.
But I can assure that they all are running well in Qt 4.2.2 but donot know why there is a problem in the Qt 4.3.2.

Even if I donot use them then still the item is not checked.

Can you provide a minimal compilable example reproducing the problem?

Does it work properly with another style, for example with plastique?

./app -style plastique

[vishal.chauhan]

Yes the problem remains even after changing the Style.

Hi,

No Answer????.
So Am I right it a problem of qt 4.3.2

The only problem I'm experiencing with 4.3.2 is that the area that responds to check state changes is a bit too far left. With 4.3.3 it works perfectly.
