Manager view interactor class.
Library: ilvgadmgr
The IlvManagerMakeStringInteractor
abstract class creates new single-line text entities, or edits single-line text objects. The interactor creates a text field object when the user presses the left mouse button in the view to which this interactor is connected. The user can then enter a new string.

Constructor.
Calls the constructor of the superclass and initializes the interactor.
manager | The manager. |
view | The manager view. |
|
virtual |
Aborts the interaction.
Called by the manager when the user changes the current interactor. It resets the interactor to a state in which it appears to have never been launched. A common implementation is to erase the ghost image. Call this member function to inhibit the interactor action in particular circumstances.
Reimplemented from IlvManagerViewInteractor.
Called to start the interaction with the text field object.
Called when the user presses the left mouse button in the working view. The default implementation creates the text field and returns IlTrue
. If you create subtypes of this class, always call this function to create the text field.
IlTrue
if the interactor accepts the point as a valid position to start the interaction. Reimplemented in IlvManagerMakeLabelInteractor.
|
pure virtual |
Finalizes the interaction.
Called when the user validates the text field. This function declaration makes this class a pure abstract class.
label | The string contained in the text field. |
Implemented in IlvManagerMakeLabelInteractor.
const char* IlvManagerMakeStringInteractor::getLabel | ( | ) |
Returns the string being edited.
Handles events for the manager view.
Called by the manager for which the interactor was created with every event it receives in the interactor view.
IlTrue
if the event is consumed, IlFalse
otherwise. Implements IlvManagerViewInteractor.
|
virtual |
Called when the manager view receives an expose event.
Called by the manager when an exposure request occurs in the interactor view to redraw shapes handled by the interactor, such as a ghost image. The basic implementation calls the member function IlvManagerViewInteractor::drawGhost()
after the clipping region has been set to the exposed area.
clip | Specifies the exposed area. |
Reimplemented from IlvManagerViewInteractor.
