//======================================

|
class CContextMenuAttachment : public LAttachment
|
|
// By adding this to a pane in constructor, and defining a corresponding menu, you get
|
|
// a context menu in that pane.
|
|
//
|
|
// Your menu should have all the possible commands. This attachment class will use the
|
|
// FindCommandStatus call for your pane, and remove any items that are not currently available
|
|
// before calling PopupMenuSelect.
|
|
//
|
|
// If necessary, your pane's FindCommandStatus can distinguish context menu calls from other
|
|
// calls by using ::StillDown(), because the normal menu enabling in PowerPlant does NOT
|
|
// happen while the mouse is pressed.
|
|
//
|
|
// This listens to mouse clicks, waits for timeout, handles popup menu etc. It will also
|
|
// handle changing the cursor if called from within AdjustCursorSelf(), etc.
|
|
//
|
|
// Must be attached via constructor, just like CPaneEnabler. [This is _so_ not true (pinkerton)]
