Or changes will just apply after a restart. Still I am not sure how to set the style upon creation. I use the following code to create it: local tree = wx.wxTreeCtrl(this, wx.wxID_ANY,wx.wxPoint(0,0), wx.wxSize(160,250),wx.wxTR_DEFAULT_STYLE + wx.wxTR_NO_LINES + wx.wxTR_HIDE_ROOT + wx.wxTR_MULTIPLE + wx.wxNO_BORDER); The styles are separated by a "+" sign, which is not standard lua so I do not know how to make a style optional. I tried to use a variable instead of "wx.wxTR_NO_LINES" and set it to either nil or "wx.wxTR_LINES". Both fail. One possibility might be to define two sets of styles, one including "wx.wxTR_NO_LINES" and the other one not. This works if you only want to make one style configuarable. Is there a better/more flexible way to define the styles? Thanks, Michael ------------------------------------------------------------------------------ Come build with us!
