TGMatrixLayout Class Reference

This layout managers does not make use of TGLayoutHints.

It arranges frames in a matrix-like way. This manager provides :

  • a column number (0 means unlimited)
  • a row number (0 means unlimited)
  • horizontal & vertical separators

Notes : If both column and row are fixed values, any remaining frames outside the count won't be managed. Unlimited rows means the frame can expand downward (the default behaviour in most UI). Both unlimited rows and columns is undefined (read: will crash the algorithm ;-). With fixed dimensions, frames are always arranged in rows. That is: 1st frame is at position (0,0), next one is at row(0), column(1) and so on... When specifying one dimension as unlimited (i.e. row=0 or column=0) the frames are arranged according to the direction of the fixed dimension. This layout manager does not make use of TGLayoutHints.
