6 // ==========================================================
7 // CDialogResizeHelper
8 // ==========================================================
9 // Usage:
10 // Put CDialogResizeHelper member in your dialog class
11 // Initialize with controls sizing info table, array of CDialogResizeHelper::Param
12 // Put CHAIN_MSG_MAP_MEMBER(m_resizer) before your dialog message handlers
13 // CDialogResizeHelper will do its own message handling without marking messages as handled, that is, your handlers of the same messages will be allowed to run.
14 // CRect minMaxRange specifies allowed size min (left&top) and max (right&bottom) values, in DLU not pixels.
15 // ==========================================================
