UControlSYNOPSIS
#include <Unidraw/uctrl.h>DESCRIPTION
UControl is an abstract class that augments InterViews' Control base class to deal with Unidraw's ControlInfo objects, which define a keyboard equivalent for the control. UControlInteractor is an abstract base class for interactors that base their appearance on the information in a ControlInfo object. UControl subclasses can use UControlInteractor subclasses to define their appearance.Unidraw-based applications needn't use UControls and UControlInteractors to help define their look and feel if Unidraw's keyboard equivalent mechanism is not needed.
UCONTROL PUBLIC OPERATIONS
- virtual void SetControlInfo(ControlInfo*)
- ControlInfo* GetControlInfo()
- Assign and retrieve the UControl's ControlInfo object.
UCONTROL PROTECTED OPERATIONS
- UControl(ControlInfo*)
- UControl(const char*, ControlInfo*)
- UControl provides protected constructors that let subclasses initialize the ControlInfo object and optionally specify their instance name.
UCONTROLINTERACTOR PUBLIC OPERATIONS
- virtual void SetControlInfo(ControlInfo*)
- ControlInfo* GetControlInfo()
- Assign and retrieve the UControlInteractor's ControlInfo object.
- virtual void Highlight(boolean)
- The UControlInteractor's appearance is defined by a Graphic object, which it builds from information in its ControlInfo object. By default, UControlInteractor highlights itself by drawing this graphic with its foreground and background colors reversed.
UCONTROLINTERACTOR PROTECTED OPERATIONS
- UControlInteractor(ControlInfo*)
- UControlInteractor()
- UControlInteractor defines two protected constructors. One takes the ControlInfo object to use as an argument. This constructor also initializes the UControlInteractor's _label protected member by calling InitLabel (described below) with the ControlInfo object. The parameterless constructor initializes _label to nil. Both constructors initialize the UControlInteractor's _picture protected member to point to an instance of a Picture object, which defines the UControlInteractor's appearance.
- virtual void Invert()
- Invert reverses _picture's colors without drawing it.
- Graphic* InitLabel(ControlInfo*)
- Create a graphic from the information stored in a ControlInfo object that defines the UControlInteractor's appearance. This operation creates a GraphicView of the ControlInfo's GraphicComp and returns a copy of the view's graphic.
