◆ AddFrame()

void TGCompositeFrame::AddFrame	(	TGFrame *	f,
		TGLayoutHints *	l = `0`
	)

virtual

Add frame to the composite frame using the specified layout hints.

If no hints are specified default hints TGLayoutHints(kLHintsNormal,0,0,0,0) will be used. Most of the time, however, you will want to provide specific hints. User specified hints can be reused many times and need to be destroyed by the user. The added frames cannot not be added to different composite frames but still need to be deleted by the user.

◆ SetCleanup()

void TGCompositeFrame::SetCleanup ( Int_t mode = kLocalCleanup )

virtual

Turn on automatic cleanup of child frames in dtor.

if mode = kNoCleanup - no automatic cleanup if mode = kLocalCleanup - automatic cleanup in this composite frame only if mode = kDeepCleanup - automatic deep cleanup in this composite frame and all child composite frames (hierarchical)

Attention! Hierarchical cleaning is dangerous and must be used with caution. There are many GUI components (in ROOT and in user code) which do not use Clean method in destructor ("custom deallocation"). Adding such component to GUI container which is using hierarchical cleaning will produce seg. violation when container is deleted. The reason is double deletion: first when Clean method is invoked, then at "custom deallocation". We are going to correct all ROOT code to make it to be consistent with hierarchical cleaning scheme.

Reimplemented from TGFrame.
