Detailed Description

Helper interface used for text dragging and dropping. Installed on same boss as text drag drop source and target.

virtual void IDragDropTextHelper::AdjustRangeFromHitTest	(	IControlView *	view,
		const UIDRef &	storyUIDRef,
		const PMReal &	hitIndex,
		const PMReal &	nextLine,
		RangeData &	adjustedRange
	)

pure virtual

Description: Adjust a range data (with correct lean) as computed by AdjustHitTestTextIndex for the story and text indices. Should have length of zero. Gives helper a chance to examine the display text index and range and alter if necessary (e.g. convert to model range, etc.).

Parameters

view	IN pointer to the control view under the mouse
storyUIDRef	IN Reference to the story to drop into (the destination)
hitIndex	IN the display text index to construct the range with
nextLine	IN the nextLine text index of the first character in the next line after the line hit (useful for computing the lean)
storyUIDRef	IN Reference to the story to drop into (the destination)
RangeData	OUT the altered text range with correct lean representing the hit location.

virtual IParcel* IDragDropTextHelper::QueryParcelFromHitObject	(	IControlView *	view,
		const PMPoint &	where,
		const IPMUnknown *	hitObj,
		const IParcel *	previousParcel
	)

pure virtual

Description: Query for an IParcel interface from an object.

Parameters

view	IN pointer to the control view under the mouse
where	IN the point in pasteboard coordinates to use
hitObj	IN an IPMUnknown* from the object to test.
previousParcel	IN an IParcel interface from a possible previous hit. May be nil, and will be nil initially.

Returns: IParcel the parcel interface from the object. Return nil if not found. Caller must release reference.

virtual ITextStoryThread* IDragDropTextHelper::QueryStoryThreadFromHitObject	(	IControlView *	view,
		const PMPoint &	where,
		const IPMUnknown *	hitObj,
		const IParcel *	previousParcel
	)

pure virtual

Description: Query for an ITextStoryThread interface from an object.

Parameters

view	IN pointer to the control view under the mouse
where	IN the point in pasteboard coordinates to use
hitObj	IN an IPMUnknown* from the object to test.
previousParcel	IN an IParcel interface from a possible previous hit. May be nil, and will be nil initially.

Returns: ITextStoryThread the text story thread interface from the object. Return nil if not found. Caller must release reference.
