View class.
Library: xviews or winviews or mviews (mutually exclusive)
When using the IlvView class hierarchy, you must specify the callback functions used to handle incoming events. The IlvDrawingView class has predefined member functions for this purpose.
| IlvDrawingView::IlvDrawingView | ( | IlvAbstractView * | parent, |
| const IlvRect & | size, | ||
| IlBoolean | visible = IlTrue |
||
| ) |
Constructor.
This constructor initializes a view object that is a child of the parent view.
| parent | The parent view. |
| size | The initial location and size of the view, in the coordinate system of parent. |

| IlvSystemView | parent, | ||
| const IlvRect & | size, | ||
| IlBoolean | visible = IlTrue |
||
| ) |
Constructor.
This constructor creates a view that is a child of the existing system view indicated by parent.
| display | The display instance. |
| parent | The parent system view. |
| size | The initial location and size of the view, in the coordinate system of the existing system view. |
| visible | Can be set to IlFalse to initially hide the window. |
| IlvDrawingView::IlvDrawingView | ( | IlvDisplay * | display, |
| IlvSystemView | available | ||
| ) |
Constructor.
This constructor creates a new view object by actually using the existing system view indicated by available.
| display | The display instance. |
| available | The system view on which this IlvDrawingView is based. |

| const char * | name, | ||
| const char * | title, | ||
| const IlvRect & | size, | ||
| IlBoolean | visible = IlTrue |
||
| ) |
Constructor.
This constructor initializes a view object that is a new top window.
| display | The display instance. |
| name | The name of this view (used by the resource association mechanism). |
| title | The title of this top window. |
| size | The initial location and size of the view, relative to the root window of display. |
| visible | Can be set to IlFalse to initially hide the window. |
| IlvDrawingView::IlvDrawingView | ( | IlvDisplay * | display, |
| const char * | name, | ||
| const char * | title, | ||
| const IlvRect & | size, | ||
| IlUInt | properties, | ||
| IlBoolean | visible = IlTrue, |
||
| IlvSystemView | transientFor = 0 |
||
| ) |
Constructor.
This constructor creates a top window, with an optional parameter properties that makes it possible to tune its aspect.
| display | The display instance. |
| name | The name of this view (used by the resource association mechanism). |
| title | The title of this top window. |
| size | The initial location and size of the view, relative to the root window of display. |
| properties | The properties of that view (see above). |
| visible | Can be set to IlFalse to initially hide the window. |
| transientFor | The possible system view for which this view is transient. If unspecified or set to 0, this view will not be transient for any view. |
|
virtual |
Draws the view contents.
This is the member function you will overload to perform the different drawing tasks that are needed by your application.
The default implementation does nothing.
| clip | The clipping region where the drawing must take place. If 0, there is no clipping region to be used. |
Reimplemented in IlvContainer.
|
virtual |
Handles a newly exposed region.
This member function is called when this view reveals new regions that must be updated.
The default implementation calls reDraw with the relevant exposed region.
| event | The event that is received for this expose event. |
Reimplemented in IlvContainer.
|
virtual |
Handles an input event.
This member function is called when an input event (keystrokes or mouse events) is received by this view.
Its default implementation does nothing.
| event | The input event that is received. |
Reimplemented in IlvContainer.
|
virtual |
Redraws the entire view.
The default implementation erases, if necessary, the background of the window then calls draw.
| clip | The clipping region to be refreshed. |
Reimplemented in IlvContainer.
