when I was constructing a dialog,I drawed some lines with "wxClientDC" class and "DrawLine" function.But when the dialog was covered by the widgets of other programs,afthe the dialog reget the focus,the lines disappeared.
I have tried many ways,such as "OnPaint()","OnMove()","Invalidate()","Update()","Refresh",but still can't solve the program.

Could you help me?

wxBufferedDC may be easier, though I didn't try myself.
