View class.
Library: xviews or winviews or mviews (mutually exclusive)
This is an abstract class without any constructor. Thus, instances can only be created from subtypes of this class. Objects of the IlvAbstractView
class and its derived subclasses give rise to actual windows or views that are displayed on your screen. A view is a visual place holder – a rectangular object on your screen – to display elements of an application. A window on the screen is an associated set of one or several views.
Every view is distinguished by its location (x, y coordinates), size (height and width), and visibility (that is, an existing view can be visible or not visible).
Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue()
, IlvValueInterface::queryValues()
, IlvValueInterface::changeValue()
, IlvValueInterface::changeValues()
. This class inherits the accessors of its superclass IlvSystemPort
and adds the following ones:
Name | Type | Equivalent methods |
---|---|---|
x | Int | globalBBox() , move() |
y | Int | globalBBox() , move() |
width | UInt | globalBBox() , resize() |
height | UInt | globalBBox() , resize() |
background | Color | getBackground() , setBackground() |
backgroundBitmap | Bitmap | getBackgroundBitmap() , setBackgroundBitmap() |
boundingBox | IlvRect | boundingBox() |

void IlvAbstractView::ensureVisible | ( | const IlvPoint & | point | ) |
Ensures that a point remains visible.
This member function makes sure the given point p is visible to the user. This is meaningful only if isScrolled
returns IlTrue
, that is, if this object is scrolled in a system scrolling view. The parent scrolling view takes care of its subwindow displacement to guarantee the visibility of p.
point | The point that is requested to remain visible. |
void IlvAbstractView::ensureVisible | ( | const IlvRect & | rect | ) |
Ensures that a rectangle remains visible.:
This member function makes sure the given rectangle rect is visible to the user. This is meaningful only if isScrolled
returns IlTrue
, that is, if this object is scrolled in a system scrolling view. The parent scrolling view takes care of its subwindow displacement to guarantee the visibility of rect.
If rect represents a bigger rectangle than the scrolling window is able to display, then the subwindow is centered in the scrolling region on the center of rect. That is, the center of rect is moved to the center of the scrolling window, but the boundaries of rect are not visible.
rect | The rectangle that is requested to remain visible. |

An IlvAbstractView
object encapsulates a real interface object of your display system (sometimes referred to as a widget). The member function getSystemView
returns this object.
The IlvSystemView
type is the basic type of your display system widgets, and is thus platform-dependent.

Queries for scrolling capabilities.
IlTrue
if this window is the subwindow of a system scrolling window (see IlvScrollView
). Scrolling windows own a single subwindow, from which they display only a rectangular region. This allows you to manipulate bigger windows than your screen can display, and navigate within these by means of a smaller rectangular area. IlBoolean IlvAbstractView::isSensitive | ( | ) | const |
Retrieves the sensitivity of this view to input events.
IlFalse
is returned, no keyboard or pointing device events are received by this object. The window is said to be sensitive if it can receive these events and isSensitive
returns IlTrue
.

|
virtual |
Sets the background color of this view.
The color is used when erasing is required. Thus, a call to setBackground
is effective only when regions are erased.
c | The new background color of this view. This color is locked, and the previous color is unlocked. |
Reimplemented in IlvContainer, and IlvContainer.
|
virtual |
Sets the background bitmap of this view.
The bitmap provided (if it is not 0
) is locked. The previous bitmap, if there was one, is unlocked. If the bitmap provided is 0
, the background color is used to ( erase the view. To remove properly a background bitmap that was previously set, you must do the following:
This code must be used also for containers (replaces manager by container in code).
Reimplemented in IlvContainer, and IlvContainer.
void IlvAbstractView::setCursor | ( | IlvCursor * | cursor | ) |
Sets the cursor for this view.
Sets the given cursor
pattern for your pointing device whenever it enters this window. This member function calls lock
on the cursor provided as an argument, then unLock
on the old cursor to release a reference to it (see IlvResource::lock
and IlvResource::unLock
).
cursor | The new cursor that is used in this view. |
IlBoolean IlvAbstractView::setFocus | ( | ) |
Sets the input focus to this view.
Gives this window entire control of keyboard events, that is it "gets the focus." When you call this function, all keyboard events are sent to this object. The only way to let another window receive keyboard events is by giving the focus to another window.
setFocus
does not lock your system permanently. void IlvAbstractView::setLayered | ( | IlBoolean | layered | ) |
Sets whether the window is layered or not.
Layered windows only work in Windows 2000 or higher systems. Layered windows are rendered in an offscreen bitmap by the system, and then blended to the screen using various attributes such as partial translucency. This attribute allows improved performance for shaped windows.
layered | The new layered value of this view. The view becomes layered if the layered argument is IlTrue . |
void IlvAbstractView::setOpacity | ( | IlvIntensity | level | ) |
Sets the opacity value of the view.
This method has only an effect on Windows 2000 and higher systems. The view must be a top window. The method setLayered(IlTrue)

void IlvAbstractView::setSensitive | ( | IlBoolean | sensitivity | ) |
Sets the sensitivity of this view to input events.
sensitivity | The new sensitivity of this view. The view becomes sensitive if the sensitivity argument is IlTrue . If sensitivity is set to IlFalse , none of the input events can reach the window. |
void IlvAbstractView::setTransparentColorKey | ( | IlvIntensity | r, |
IlvIntensity | g, | ||
IlvIntensity | b | ||
) |
Sets the transparency color key value.
This method has only an effect on Windows 2000 and higher systems. The view must be a top window. All pixels painted in the window using this color will be transparent. The method setLayered(IlTrue)
is called to set the layered attribute.
r | The red component value of the color. |
g | The green component value of the color. |
b | The blue component value of the color. |
void IlvAbstractView::setWindowProc | ( | IlvWindowProc | windowProc, |
IlAny | procArgument = 0 |
||
) |
Sets a Windows window procedure.
This member function is available only for Windows ports of Rogue Wave Views.

windowProc | The new window procedure that is used for this view. |
procArgument | The user-defined argument that the window procedure will receive. |
IlvWindowProc
, removeWindowProc
.
|
virtual |
Shows the view.
Displays the window on the screen. A window can be created in such a way that you cannot see it upon creation, which allows you to draw on that window before it is displayed.
Reimplemented in IlvView, IlvContainer, and IlvContainer.
|
virtual |
Retrieves the visible part of the view.
rect | Is set to the visible rectangle of this window. This return value is meaningful only if this object is the subwindow of a scrolling window (that is, has a hidden area because of the view hierarchy). If this is not the case, sizeVisible has the same meaning as boundingBox . |
