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.

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
pThe 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 *  lines,
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
linesThe array of strings contained in the text object.
countThe 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. You should never modify or delete this array.
Parameters
countUsed to return the number of strings in the array.
void IlvManagerMakeTextInteractor::setLines ( const char *const *  lines,
IlUShort  count,
IlBoolean  redraw = IlTrue 
)

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

Parameters
linesThe array of strings.
countThe number of strings in the array.
redrawIf set to IlTrue, the text object is redrawn.
