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.

Constructor.
Calls the constructor of the superclass and performs internal initializations.
manager | The manager. |
view | The manager view. |
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.
p | The position of the event that initiated the interaction. |
IlTrue
if the interactor accepts the point as a valid position to start the interaction. Reimplemented in IlvManagerMakeListLabelInteractor.
|
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.
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.
count | Used 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.
lines | The array of strings. |
count | The number of strings in the array. |
redraw | If set to IlTrue , the text object is redrawn. |
