TGTableLayoutHints Class Reference

This class describes layout hints used by the TGTableLayout class.

It specifies the column/row division number on which to attach the child frame. This number starts from 0 and goes to #_columns/#_rows respectively (0 indicates the first row/column).

Below are described all parameters of TGTableLayoutHints constructor

  • attach_left - the column to the left of the widget;
  • attach_right - the column to the right of the widget;
  • attach_top - the row above the widget;
  • attach_bottom - the row below the widget;
  • hints - layout hints (combination of ELayoutHints)

The next parameters determine the extra padding added around the child frame. By default these are 0.

  • padleft - determines the extra padding added on the left
  • padright - determines the extra padding added on the right
  • padtop - determines the extra padding added on the top
  • padbottom - determines the extra padding added on the bottom
