Constructor Detail

IlvSelectInteractor

public IlvSelectInteractor()

Constructs and initializes a new instance of a select interactor.

Method Detail

setOpaqueDragSelection

public void setOpaqueDragSelection(boolean set)

Sets the interactor in Opaque Multiple Selection mode. The interactor has two modes to select graphic objects by dragging a rectangle around them: The Opaque Multiple Selection mode and the Ghost Multiple Selection mode.

In Opaque Multiple Selection mode, while the user drags the selection rectangle, the previous rectangle is erased by invalidating the corresponding regions of the view using IlvManagerView.invalidateRect(ilog.views.IlvRect) and requesting a redraw using IlvManagerView.reDrawViews(). This mode may be slower because it requires partial redraws of the manager, but it is safer because it behaves well if animated gif images are used (inside IlvIcon graphic objects).

In Ghost Multiple Selection mode, the previous selection rectangle is erased by drawing it again (in XOR mode).

The default mode is the Ghost Multiple Selection mode.

isOpaqueDragSelection

public boolean isOpaqueDragSelection()

Returns an indication of whether the interactor is in Opaque Multiple Selection mode or not.

Since:: JViews 5.0
See Also:: setOpaqueDragSelection(boolean)

setMultipleSelectionMode

public void setMultipleSelectionMode(boolean v)

Lets you enable or disable the mode that allows you to select several objects simultaneously.

isMultipleSelectionMode

public boolean isMultipleSelectionMode()

Returns true if the interactor allows the user to select multiple objects simultaneously.

setMoveAllowed

public void setMoveAllowed(boolean v)

Lets you enable or disable the mode that allows you to move objects with this interactor.

isMoveAllowed

public boolean isMoveAllowed()

Returns true if the interactor lets the user move objects, false otherwise.

setLinksFollowEndNodes

public void setLinksFollowEndNodes(boolean v)

Sets whether the bends of unselected links will move when both end nodes are selected and move.

By default, the bends of a link only move when the link is selected. If a group of nodes is selected and move, the straight links always follow the nodes, even if they are not selected, but the bends of unselected nonstraight links stay at the old position. However, it may be more comfortable if all links automatically follow the nodes, even if they are not straight and not explicitly selected. In this case, you should enable this option.

Since:: JViews 5.5

isLinksFollowEndNodes

public boolean isLinksFollowEndNodes()

Returns true if the bends of unselected links will move when both end nodes are selected and move.

Since:: JViews 5.5

setHyperEdgesFollowEndNodes

public void setHyperEdgesFollowEndNodes(boolean v)

Sets whether the segments of unselected hyperedges will move when all end nodes of the hyperedge are selected and moved.

By default, the segments of a hyperedge only move when the hyperedge is selected. If a group of nodes is selected and moved, the hyperedges consisting of only one segment always follow the nodes, even if they are not selected, but the multiple segments of the other unselected hyperedges stay at the old position. However, it may be more comfortable if all hyperedges automatically follow the nodes. In this case, you should enable this option.

Since:: JViews 8.0

isHyperEdgesFollowEndNodes

public boolean isHyperEdgesFollowEndNodes()

Returns true if the segments of unselected hyperedges will move when all end nodes of the hyperedge are selected and moved.

Since:: JViews 8.0

setOpaqueMove

public void setOpaqueMove(boolean set)

Sets the interactor in Opaque Move mode. The interactor has two modes to move a graphic object: The Opaque Move mode and the Ghost Move mode. In Opaque Move mode, the position of the object that the user moves is changed for each drag event. In Ghost Move mode, the position of the object is changed only when the user releases the mouse button. The default mode is the Ghost Move mode.

See Also:: isOpaqueMove()

isOpaqueMove

public boolean isOpaqueMove()

Returns an indication of whether the interactor is in Opaque Move mode or not.

See Also:: setOpaqueMove(boolean)

setOpaqueResize

public void setOpaqueResize(boolean set)

Sets the interactor in Opaque Resize mode. The interactor has two modes to resize a graphic object: The Opaque Resize mode and the Ghost Resize mode. In Opaque Resize mode, the size of the object that the user resizes is changed for each drag event. In Ghost Resize mode, the size of the object is changed only when the user releases the mouse button. The default mode is the Ghost Resize mode.

Since:: JViews 5.0
See Also:: isOpaqueResize()

isOpaqueResize

public boolean isOpaqueResize()

Returns an indication of whether the interactor is in Opaque Resize mode or not.

Since:: JViews 5.0

Sets the interactor in Opaque PolyPoints Edition mode. The interactor has two modes to edit polypoints objects: The Opaque PolyPoints Edition mode and the Ghost PolyPoints Edition mode. In Opaque PolyPoints Edition mode, the polypoints object that the user edits is changed for each drag event. In Ghost PolyPoints Edition mode, the polypoints object is changed only when the user releases the mouse button. The default mode is the Ghost PolyPoints Edition mode.

Since:: JViews 5.0
See Also:: isOpaquePolyPointsEdition()

getMoveSelectionManager

public IlvManager getMoveSelectionManager()

Returns the manager that contains the selected objects to be moved. This method is called by the interactor returned by getMoveSelectionInteractor(). This manager may be different from the manager returned by IlvManagerViewInteractor.getManager() if the interactor is working on a submanager.

Since:: JViews 5.0

setMultipleSelectionModifier

public void setMultipleSelectionModifier(int modifier)

Sets the multiple selection modifier. The default modifier is InputEvent.SHIFT_MASK. This method can be used to set normal modifiers and extended modifiers (see java.awt.event.InputEvent.getModifiersEx() since JDK 1.4).

Note: In the mask, InputEvent.ALT_DOWN_MASK should be used instead of InputEvent.ALT_MASK, and InputEvent.META_DOWN_MASK should be used instead of InputEvent.META_MASK, because the values of ALT_MASK/BUTTON2_MASK and META_MASK/BUTTON3_MASK overlap.

Since JViews 7.0, the modifier bitmask is checked exactly. Before JViews 7.0, specifying for instance SHIFT became active when pressed alone or in combination with any other modifier key. Since JViews 7.0, it becomes active only when pressed alone. This allows you to use at the same time a greater range of modifier combinations for different purposes.

Since:: JViews 5.0
See Also:: getMultipleSelectionModifier(), getMultipleSelectionModifierEx(), isMultipleSelectionModifierDown(java.awt.event.MouseEvent)

getMultipleSelectionModifier

public int getMultipleSelectionModifier()

Returns the multiple selection modifier. The default modifier is InputEvent.SHIFT_MASK.

Since:: JViews 5.0
See Also:: setMultipleSelectionModifier(int), isMultipleSelectionModifierDown(java.awt.event.MouseEvent)

getMultipleSelectionModifierEx

public int getMultipleSelectionModifierEx()

Returns the extended multiple selection modifier. The default modifier is InputEvent.SHIFT_DOWN_MASK. See java.awt.event.InputEvent.getModifiersEx() since JDK 1.4 for information about extended modifiers. This mask is computed from setMultipleSelectionModifier(int).

Since:: JViews 7.5
See Also:: setMultipleSelectionModifier(int), isMultipleSelectionModifierDown(java.awt.event.MouseEvent)

isMultipleSelectionModifierDown

protected boolean isMultipleSelectionModifierDown(MouseEvent event)

Tests if the multiple selection modifier is currently down. The method compares the current modifiers of the event with the modifier returned by the method getMultipleSelectionModifierEx(). This is used by the interactor to determine if we are doing a multiple selection or not. The default modifier is InputEvent.SHIFT_DOWN_MASK.

See Also:: setMultipleSelectionModifier(int)

setSelectionModifier

public void setSelectionModifier(int modifier)

Sets the selection modifier. This is used by the interactor to determine if a mouse pressed corresponds to the start of the drag of a selection rectangle. If this modifier is not down, such a mouse pressed over a graphic object produces the move of the object instead. The default modifier is InputEvent.CTRL_MASK. This method can be used to set normal modifiers and extended modifiers (see java.awt.event.InputEvent.getModifiersEx() since JDK 1.4).

Since JViews 7.0, the modifier bitmask is checked exactly. Before JViews 7.0, specifying for instance CTRL became active when pressed alone or in combination with any other modifier key. Since JViews 7.0, it becomes active only when pressed alone. This allows for a greater range of modifier combinations to be used at the same time for different purposes.

Since:: JViews 5.0

See Also:: setSelectionModifier(int), isSelectionModifierDown(java.awt.event.MouseEvent)

getSelectionModifierEx

public int getSelectionModifierEx()

Returns the extended selection modifier. The default modifier is InputEvent.CTRL_DOWN_MASK. See java.awt.event.InputEvent.getModifiersEx() since JDK 1.4 for information about extended modifiers. This mask is computed from setSelectionModifier(int).

Since:: JViews 7.5
See Also:: setSelectionModifier(int), isSelectionModifierDown(java.awt.event.MouseEvent)

isSelectionModifierDown

protected boolean isSelectionModifierDown(MouseEvent event)

Tests if the selection modifier is currently down. The method compares the current modifiers of the event with the modifier returned by the method getSelectionModifierEx(). This is used by the interactor to determine if a mouse pressed corresponds to the start of the drag of a selection rectangle. If this modifier is not down, such a mouse pressed over a graphic object produces the move of the object instead. The default modifier is InputEvent.CTRL_DOWN_MASK.

Since:: JViews 5.0
See Also:: setSelectionModifier(int)

mouseDownMultipleSelection

protected void mouseDownMultipleSelection(MouseEvent event)

Called when a mouse button is down and the multiple selection modifier is also down. If an object is under the mouse, it will be added to the selection.
