Method Detail

getId

public java.lang.String getId()

Specified by:

getId in interface StatusBarWidgetFactory

Returns:

Widget identifier. Used to store visibility settings.

getDisplayName

public java.lang.String getDisplayName()

Specified by:

getDisplayName in interface StatusBarWidgetFactory

Returns:

Widget's display name. Used to refer a widget in UI, e.g. for "Enable/disable <display name>" action names or for checkbox texts in settings.

isAvailable

public boolean isAvailable(Project project)

Description copied from interface: StatusBarWidgetFactory

Returns availability of widget.

`False` means that IDE won't try to create a widget or will dispose it on StatusBarWidgetsManager.updateWidget(java.lang.Class<? extends com.intellij.openapi.wm.StatusBarWidgetFactory>) call.

E.g. `false` can be returned for

• notifications widget if Event log is shown as a tool window
• memory indicator widget if it is disabled in the appearance settings
• git widget if there are no git repos in a project

Whenever availability is changed, you need to call StatusBarWidgetsManager.updateWidget(StatusBarWidgetFactory) explicitly to get status bar updated.

Specified by:

isAvailable in interface StatusBarWidgetFactory

createWidget

public StatusBarWidget createWidget(Project project)

Description copied from interface: StatusBarWidgetFactory

Creates a widget to be added to the status bar.

Once the method is invoked on project initialization, the widget won't be recreated or disposed implicitly.

You may need to recreate it if:

its availability has changed. See StatusBarWidgetFactory.isAvailable(Project) its visibility has changed. See com.intellij.openapi.wm.impl.status.widget.StatusBarWidgetSettings

To do this, you need to explicitly invoke StatusBarWidgetsManager.updateWidget(StatusBarWidgetFactory) to recreate the widget and re-add it to the status bar.

Specified by:

createWidget in interface StatusBarWidgetFactory

disposeWidget

public void disposeWidget(StatusBarWidget widget)

Specified by:

disposeWidget in interface StatusBarWidgetFactory

isConfigurable

public boolean isConfigurable()

Memory indicator is controlled by UISettings

Specified by:

isConfigurable in interface StatusBarWidgetFactory

Returns:

Returns whether the user should be able to enable or disable the widget.

Some widgets are controlled by application-level settings (e.g., Memory indicator) or cannot be disabled (e.g., Write thread indicator) and thus shouldn't be configurable via status bar context menu or settings.

canBeEnabledOn

public boolean canBeEnabledOn(StatusBar statusBar)

Memory indicator is controlled by UISettings

Specified by:

canBeEnabledOn in interface StatusBarWidgetFactory

Returns:

Returns whether the widget can be enabled on the given status bar right now. Status bar's context menu with enable/disable action depends on the result of this method.

It's better to have this method aligned with EditorBasedStatusBarPopup.WidgetState.HIDDEN, whenever state is HIDDEN, this method should return false. Otherwise enabling widget via context menu won't take any visual effect.

E.g. EditorBasedWidget are available if editor is opened in a frame that given status bar is attached to
