Button texts set with a QStringListModel

Hi,

I tried to display a GridLayout of Buttons for whom Button texts are given by a QStringListModel. I use the "display" role to set the text attribute of the Button element.. it seems that it doesn't work (it displays a number in the Button text). 

A Solution : Add a Text element in the Button.

Please find in attachment a snippet which reproduce the issue. To solve the issue, uncomment the Text element.

Regards.

David.
