Detailed Description

Manager view interactor class.

Library: ilvadvgadmgr

The IlvManagerMakeTextInteractor abstract class lets you edit multiline text objects or create new ones. When the user presses the left mouse button in the view to which this interactor is connected, a temporary text object (IlvText) is created. This lets the user enter some text. The validation is made by double-clicking in the working area; the virtual member function doIt is then called.

IlvLabel, IlvListLabel, IlvManagerMakeListLabelInteractor, IlvManagerMakeStringInteractor, IlvStringList, IlvText.

Member Function Documentation

virtual IlBoolean IlvManagerMakeTextInteractor::accept

(

IlvPoint &

p

)

[virtual]

Called to start the interaction with the text object.

Is called when the user presses the left mouse button in the working view. The default implementation creates the text object at position p and returns IlTrue. If you create subtypes of this class, always call this function to create the text object.

Parameters:

p

The position of the event that initiated the interaction.

Returns:

IlTrue if the interactor accepts the point as a valid position to start the interaction.

Reimplemented in IlvManagerMakeListLabelInteractor.

virtual void IlvManagerMakeTextInteractor::doIt	(	const char *const *	s,
		IlUShort	count
	)			[pure virtual]

Finalizes the interaction.

This virtual member function is called when the user validates the text entry. The text contents is passed to this function. Note that this function declaration makes this class a pure abstract class.

Parameters:

	lines	The array of strings contained in the text object.
	count	The number of strings in the array.

Implemented in IlvManagerMakeListLabelInteractor.

const char* const* IlvManagerMakeTextInteractor::getLines

(

IlUShort &

count

)

const

Returns the array of character strings being edited.

Returns:

The array of strings that are currently being edited.

Parameters:

count

Used to return the number of strings in the array. You should never modify or delete this array.

void IlvManagerMakeTextInteractor::setLines	(	const char *const *	s,
		IlUShort	count,
		IlBoolean	redraw = IlTrue
	)

Sets the contents of the text object to the specified array of strings.

Parameters:

	lines	The array of strings.
	count	The number of strings in the array.
	redraw	If set to IlTrue, the text object is redrawn.
