Interface ISection
- All Known Implementing Classes:
AbstractOverridableTabListPropertySection,AbstractPropertySection,AdvancedPropertySection
The lifecycle of an ISection is as follows:
ISection.createControls()ISection.setInput()ISection.aboutToBeShown()ISection.refresh()ISection.aboutToBeHidden()ISection.dispose()
Implementors of this class should be aware that a section instance might be
reused for different input objects (as long as they are valid section
inputs). It means that ISection.setInput can be called at any
time between ISection.createControls and
ISection.dispose.
When an input change event occurs, such as a tab selection or a workbench selection change, an ISection is sent:
ISection.setInput()ISection.refresh()
When an part activation event occurs, such as the contributor part activation event, an ISection is sent:
ISection.setInput()ISection.aboutToBeShown()ISection.refresh()ISection.setInput()ISection.refresh()
This is because both a tab selection event and an input selection event have occurred.
This interface should not be extended or implemented. New section instances
should be created using AbstractPropertySection.

Method Details
-
createControls
Creates the controls for the section.Clients should take advantage of the widget factory provided by the framework to achieve a common look between property sections.
- Parameters:
parent- the parent composite for the section.tabbedPropertySheetPage- the tabbed property sheet page.- See Also:
-
setInput
Notifies the section that the workbench selection has changed.- Parameters:
part- The active workbench part.selection- The active selection in the workbench part.
-
aboutToBeShown
void aboutToBeShown()Notifies the section that its controls are about to be shown. It is expected that sections enable domain related functions in this method, most commonly add listeners.Since the controls are not visible, the section should wait for the refresh() before updating the section controls.
-
aboutToBeHidden
void aboutToBeHidden()Notifies the section that its controls are about to be hidden. It is expected that sections disable domain related functions in this method, most commonly remove listeners. -
dispose
void dispose()Dispose this section. -
getMinimumHeight
int getMinimumHeight()Returns the minimum height needed by this section. A return value ofSWT.DEFAULTindicates that no minimum height is defined.- Returns:
- the minimum height needed by this section.
-
shouldUseExtraSpace
boolean shouldUseExtraSpace()Determine whether this section would like extra height space in case there is some left. Normally this is true when the section is the last to be displayed on a tab or is the only section on a tab.- Returns:
trueif this section would like extra height space.
-
refresh
void refresh()Refresh the contents of the controls displayed in this section.
