The module sizer uses the maximum best width of the setting     edit controls to compute the column widths, then it sets the text     controls to wrap within the remaining space, then it uses the best     height of each text control to lay out the rows. Calculate the minimum from the edit controls.  Returns a         wx.Size where the height is the total height of the grid and         the width is self.__min_text_width plus the widths of the edit         controls and help controls. # This happens, hopefully transiently, on the Mac Return a wx.Size with the total height of the controls in         column j and the maximum of their widths. Recalculate the sizes of our items, resizing the text boxes         as we go. # # Change all static text controls to wrap at the text width. Then # ask the items how high they are and do the layout of the line. # # # A line spans both columns # # make the divider height the same as a text row plus some # This happens, hopefully transiently, on the Mac
