ExpandoTextCtrl

The ExpandoTextCtrl is a multi-line wx.TextCtrl that will adjust its height on the fly as needed to accomodate the number of lines needed to display the current content of the control. It is assumed that the width of the control will be a fixed value and that only the height will be adjusted automatically. If the control is used in a sizer then the width should be set as part of the initial or min size of the control.
