public class IlpViewRenderer
extends ilog.cpl.graph.css.renderer.IlpViewRenderer

This class gives control over the view of an IlpNetworkView.

This class shows all the properties that can be customized in the network view using cascading style sheets.

The CSS configuration can be applied to the network component, using IlpGraphView.setStyleSheets(java.lang.String[]).

To customize the network view programmatically, use IlpNetworkView.

This class is a CSS JavaBean that can be customized. It can be configured as follows in a CSS file: 

 View {
   horizontalScrollBarPolicy: Never;
   verticalScrollBarPolicy: Never;
   keepingAspectRatio: true;
 }

The value in CSS, denotes the policy that is used to specify the presence or absence of the specified scrollbar. The value Always means that the scrollbar is visible; Never means that it is not visible and AsNeeded means that it will be displayed or not according to the contents of the view.

The property keepingAspectRatio configures if the aspect ratio of the main window is kept when a zoom transformer are applied.

The properties minZoomXFactor, minZoomYFactor, maxZoomXFactor and maxZoomYFactor configure the minimal and maximal zoom factors that will be accepted by the main window.

The properties wheelZoomingEnabled and wheelScrollingEnabled configure whether the graph view will respond to mouse wheel events.

JTGO 3.5

public IlpViewRenderer()
Method Detail

isHorizontalScrollBarVisible

public boolean isHorizontalScrollBarVisible()
Returns true if the horizontal scrollbar is visible.

Overrides:
isHorizontalScrollBarVisible in class ilog.cpl.graph.css.renderer.IlpViewRenderer

setHorizontalScrollBarVisible

public void setHorizontalScrollBarVisible(boolean set)
Shows or hides the horizontal scrollbar.

This property can be used to temporarily change the visibility of the scrollbar. In order to control the visibility permanently, use the scrollbar policy. The policy HORIZONTAL_SCROLLBAR_AS_NEEDED modifies the scrollbar when necessary to change its visibility.

Overrides:
setHorizontalScrollBarVisible in class ilog.cpl.graph.css.renderer.IlpViewRenderer
Parameters:
set - If this parameter is true, the scrollbar will be shown.
See Also:
setHorizontalScrollBarPolicy(int)

getHorizontalScrollBarPolicy

public int getHorizontalScrollBarPolicy()
Returns the horizontal scrollbar policy value.

Overrides:
getHorizontalScrollBarPolicy in class ilog.cpl.graph.css.renderer.IlpViewRenderer
Since:
JViews 7.5
See Also:
setHorizontalScrollBarPolicy(int)

setHorizontalScrollBarPolicy

public void setHorizontalScrollBarPolicy(int policy)
Sets the policy when the horizontal scrollbar appears. Legal values are:

Overrides:
setHorizontalScrollBarPolicy in class ilog.cpl.graph.css.renderer.IlpViewRenderer
Parameters:
policy - one of the three values listed above
Throws:
IllegalArgumentException - if policy is not one of the legal values shown above
Since:
JViews 7.5
See Also:

setVerticalScrollBarVisible

public void setVerticalScrollBarVisible(boolean set)
Shows or hides the vertical scrollbar.

This property can be used to temporarily change the visibility of the scrollbar. In order to control the visibility permanently, use the scrollbar policy. The policy VERTICAL_SCROLLBAR_AS_NEEDED modifies the scrollbar when necessary to change its visibility.
