Laboratoire ICAR » Plateforme TXM

In last discussions, it has been decided to automatically give the focus to the chart component on first chart editor creation/opening, on double click on a tree node result and on click on the tab title, and to discuss later about focus policy of other TXM command editors.

NOTE: the events of SWT and AWT are not managed the same way on Windows and Linux (even with same openJDK 6 build) and on Mac OS X (Apple 6 JDK).

Windows¶

on mouse entering a chart editor, the AWT event is fired but the SWT is not fired. The AWT event is fired even if the SWT editor has not the focus.

Linux¶

on mouse entering a chart editor, the AWT event is fired but the SWT is not fired. The AWT event is fired even if the SWT editor has not the focus. (The problem here is that the tool tips don't appear if the chart editor has not the focus unlike the Windows behavior)

Mac OS X¶

on mouse entering a chart editor, if the chart editor has the focus, both the AWT and SWT events are fired. If the editor has not the focus, only the SWT event is fired.

See: org.txm.rcp.chartsengine.base.SWTChartsComponentProvider.initializeAWTDelegationListeners(...).new MouseListener() {...}.mousePressed(MouseEvent)
if we need to activate() the editor part on mouse pressed.

1) This issue needs a full rewriting, first notes here: https://groupes.renater.fr/wiki/txm-users/public/retours_de_bugs_logiciel/txm_0.8.0#visualisations_graphiques_d_une_maniere_generale

Windows

- ouverture de l'éditeur

SwingChartComposite.SwingChartComposite(...).new WindowFocusListener() {...}.windowGainedFocus()
SwingChartComposite.SwingChartComposite(...).new FocusListener() {...}.focusGained()

- appelé grâce au ChartEditor.setFocus() qui appelle Composite.setFocus() qui semble trigger les listener AWT en donnant le focus à la Frame

- ne transmet pas l'état Activate à l'EditorPart

- clic à l'extérieur de la Frame (barres d'outils inclues)
Cela dépend si l'éditeur est déjà actif :
- S'il n'est pas actif, ça le rend actif donc appelle le set focus qui redonne le focus Swing

- S'il est déjà actif, le focus Swing est lost et pas redonné

3) Tests have been done with the library JFreeChartFX based on Java FX. It seems to fix all the focus and Editor activation bugs but not the RCP Context menu contribution based on context activation. It breaks HTML Swing tooltip and also few modifications are needed to well manage some callback events (eg. Progression to Concordance, etc.)
