Overview |
Derived from class
PegThing
|
|
|
|
The PegIcon class provides a simple bitmap display object.
A PegIcon object can be used to represent another object.
The PegIcon object can be assigned a pointer to another object
which the PegIcon object is to represent. In this case, the
PegIcon object acts as a proxy for the other object, called the
proxy object.
When the PegIcon is selected, it will
add its proxy object to the parent of the PegIcon and then
destroy itself, eliminating the PegIcon object which
has served its purpose.
A window object uses a PegIcon object as a proxy when
the window is minimized. For example, a PegDecoratedWindow
object will create an instance of a PegIcon when the window
is minimized. The PegIcon object is added to the
window's parent and the window is then removed from its parent.
A PegIcon object
with no proxy object assigned to it can be used as a simple mechanism for
displaying a PegBitmap bitmap image.

Bitmap Structure (PegBitmap)
Constructors:
|
|
 |
PegIcon(PegThing *pProxy,
|
| |
PegBitmap *pbitmap = NULL,
|
| |
WORD wId = 0, WORD wStyle = FF_NONE)
|
This constructor
creates a PegIcon which represents (is proxy for) another object.
|
|
|
|
PegIcon(const PegRect &Rect,
|
| |
PegBitmap *pbitmap,
|
| |
WORD wId = 0, WORD wStyle = FF_NONE)
|
This constructor creates a PegIcon that will simply display
a bitmap. The size and location of the bitmap is determined by
parameter Rect.
|
|
|
|
PegIcon(PegBitmap *pbitmap,
|
| |
WORD wId = 0, WORD wStyle = FF_NONE)
|
This constructor creates a PegIcon that will display
a bitmap. The icon will adjust its size to match the bitmap dimensions.
Your application can immediately use the Resize() function
to position the icon.
Public Functions:
|
|
|
|
virtual void Draw(void)
|
The PegIcon class overrides
the Draw() function to draw the icon bitmap.
|
|
|
|
virtual PegBitmap *GetIcon(void){return mpBitmap;}
|
This inline function
returns the address of the PegBitmap object which describes
the bitmap associated with the PegIcon.
|
|
|
|
virtual PegThing *GetProxy(void) {return mpProxy;}
|
This inline function
returns the address of the object that is represented by the
PegIcon.
|
|
|
|
virtual SIGNED Message(const PegMessage &Mesg)
|
The PegIcon class catches
PM_LBUTTONUP messages.
|
|
 |
virtual void SetIcon(PegBitmap *nbm) { mpBitmap = nbm;}
|
This inline function
can be used to assign the PegBitmap object to be used
as the PegIcon bitmap.
|
|
|
|
virtual void SetProxy(PegThing *pNew) {mpProxy = pNew;}
|
This inline function
can be used to assign or alter the object represented by the
PegIcon object.
The following are examples of PegIcon objects:
