Having QML TreeView rows that fit contents

dzimiwine

Hi,
Is there a way to have rows in a QML TreeView to fit their contents when using itemDelegate or rowDelegate? Basically, I use a custom itemDelegate (Rectangle+Layout+Text+Image) but I cannot predetermine the height of each row as it depends on its contents.

Regards,

I am having the same problem. I would like to have text wrap and have the row height expand correctly to display the text based on the size of parent. if I have '\n' in the display text the row shows half of text from both lines. Is there a way using the delegates to tell the QML Treeview to adjust the height?

@dzimiwine For now you can make use of the private properties. Eg.

TreeView {
   id: tree
   Component.onCompleted: {
       __currentRow = 0;
       var rowheight = tree.__currentRowItem.height
       console.log(rowheight)
   }
}

But note that these are still under development and hence its implementation or the property name itself may change in future.

I can change the row height of a top level item, but I don't see how I can adjust the height for the children. Is there away using one of the delegates to change the row height of a child based it's Role?

Thanks for your reply.
I am not sure it is going to work as I need to do it for sub items. I will try few things and probably come back to you.
