Signals

Many controls send signals to their parent. Individual signals can be enabled or disabled with PegThing's Method SetSignals. By default, all signals are enabled if the control as an ID value other than 0.

Signals are send as PegMessages. The sending object's ID and the signals values are passed in wType using macro SIGNAL(). pSource holds a pointer to the sending object. iData is the sending object ID value. lData will usually contain data associated with signal. For example, the PSF_SCROLL_CHANGE signal sent by a scroll bar has the current scroll position in lData. When the signal is associated with another object, lData will contain the ID of that object. For example, PegTreeView will set lData to the ID of selected/unselected object in all PSF_NODE_... signals.
