KDGantt Chart Layout Help

[Phamy1289]

My gantt chart looks a bit strange. The bars are not lined up with the information on the left and is there a way to have the columns on the left fill the rest of the layout?

Hi,

Since it's a QAbstractItemView, you can configure its horizontal header view and to either make the last column stretch or all of them.

I found it. I had to get access to the left pane and then set the width. Thank you for the help!

view->leftView()->setMaximumWidth(100);
