Constructor Details

FilteredTree
Create a new instance of the receiver. Subclasses that wish to override the default creation behavior may use this constructor, but must ensure that theinit(composite, int, PatternFilter)method is called in the overriding constructor. *WARNING: Passing false as parameter for useFastHashLookup results in a slow performing tree and should not be used if the underlying data model uses a stable and correct hashCode and equals implementation.
- Parameters:
parent- the parentCompositeuseNewLook- ignored, keep for API complianceuseFastHashLookup- true, if tree should use fast hashlookup, false, if the tree should be slow but working for data with mutable or broken hashcode implementation. Only used if treeViewer is already initialized- Since:
- 3.116
-
FilteredTree
public FilteredTree(Composite parent, int treeStyle, PatternFilter filter, boolean useNewLook, boolean useFastHashLookup) CallsFilteredTree(Composite, int, PatternFilter, boolean, boolean, long)with a default refresh time- Since:
- 3.116
-
FilteredTree
public FilteredTree(Composite parent, int treeStyle, PatternFilter filter, boolean useNewLook, boolean useFastHashLookup, long refreshJobDelayInMillis) Create a new instance of the receiver.WARNING: Passing false as parameter for useFastHashLookup results in a slow performing tree and should not be used if the underlying data model uses a stable and correct hashCode and equals implementation.
- Parameters:
parent- the parentCompositetreeStyle- the style bits for theTreefilter- the filter to be useduseNewLook- ignored, keep for API complianceuseFastHashLookup- true, if tree should use fast hash lookup, false, if the tree should be slow but working for data with mutable or broken hashcode implementation. Only used if treeViewer is already initializedrefreshJobDelayInMillis- refresh delay in ms, the time to expand the tree after debounce- Since:
- 3.132

init
Description copied from class:AbstractFilteredViewerCompositeCreate the filtered viewer.- Overrides:
initin classAbstractFilteredViewerComposite<PatternFilter>- Parameters:
treeStyle- the style bits for the viewer'sControlfilter- the filter to be used
-
createControl
Description copied from class:AbstractFilteredViewerCompositeCreate the filtered viewer's controls. Subclasses should override.- Overrides:
createControlin classAbstractFilteredViewerComposite<PatternFilter>- Parameters:
parent- the parenttreeStyle- SWT style bits used to create the control
-
createTreeControl
Creates and set up the tree and tree viewer. This method callsdoCreateTreeViewer(Composite, int)to create the tree viewer. Subclasses should overridedoCreateTreeViewer(Composite, int)instead of overriding this method.- Parameters:
parent- parentCompositestyle- SWT style bits used to create the tree- Returns:
- the tree
-
doCreateTreeViewer
Creates the tree viewer. Subclasses may override.- Parameters:
parent- the parent compositestyle- SWT style bits used to create the tree viewer- Returns:
- the tree viewer
- Since:
- 3.3
-
doCreateRefreshJob
Creates a workbench job that will refresh the tree based on the current filter text. Subclasses may override.- Returns:
- a workbench job that can be scheduled to refresh the tree
- Since:
- 3.4
-
updateToolbar
protected void updateToolbar(boolean visible) Updates the toolbar. The default implementation does nothing. Subclasses may override.- Parameters:
visible- boolean
-
createFilterText
Creates the filter text and adds listeners. This method callsdoCreateFilterText(Composite)to create the text control. Subclasses should overridedoCreateFilterText(Composite)instead of overriding this method.- Overrides:
createFilterTextin classAbstractFilteredViewerComposite<PatternFilter>- Parameters:
parent-Compositeof the filter text
-
updateTreeSelection
protected void updateTreeSelection(boolean setFocus) Updates the selection in the tree, based on the filter text.- Parameters:
setFocus-trueif the focus should be set on the tree,falseotherwise- Since:
- 3.105
-
doCreateFilterText
Description copied from class:AbstractFilteredViewerCompositeCreates the text control for entering the filter text. Subclasses may override.- Specified by:
doCreateFilterTextin classAbstractFilteredViewerComposite<PatternFilter>- Parameters:
parent- the parent composite- Returns:
- the text widget
-

protected void textChanged()Description copied from class:AbstractFilteredViewerCompositeUpdate the receiver after the text has changed.- Specified by:
textChangedin classAbstractFilteredViewerComposite<PatternFilter>
-
getPatternFilter
Description copied from class:AbstractFilteredViewerCompositeReturns the pattern filter used by this tree.- Overrides:
getPatternFilterin classAbstractFilteredViewerComposite<PatternFilter>- Returns:

getViewerin classAbstractFilteredViewerComposite<PatternFilter>- Returns:
- the structured viewer
-
setQuickSelectionMode
public void setQuickSelectionMode(boolean enabled) Sets whether this filtered tree is used to make quick selections. In this mode the first match in the tree is automatically selected while filtering and the 'Enter' key is not used to move the focus to the tree.By default, this is set to
false.- Parameters:
enabled-trueif this filtered tree is used to make quick selections,falseotherwise- Since:
- 3.105
-
getBoldFont
Return a bold font if the given element matches the given pattern. Clients can opt to call this method from a Viewer's label provider to get a bold font for which to highlight the given element in the tree.- Parameters:
