* NEW: New API for returning the parent (event observer) of an object. [COMPILER] * BUG: Setting a property without having to use ME is possible now, if the property is defined in the same file of course. * NEW: Mid$() can be used on the left side of an assignment. [GB.FORM] * BUG: ValueBox now reformats its contents after its Value property has been set. [GB.GTK] * BUG: Composed keys are correctly handled again by KeyPress events, but the SCIM input method does not work yet. * BUG: Form are their own event observer only if no event observer is defined at form instanciation. * BUG: The default tray icon is the same as gb.qt now. [GB.QT] * BUG: TrayIcon objects are correctly destroyed at program exit. * BUG: Form are their own event observer only if no event observer is defined at form instanciation. * BUG: TrayIcon Width, Height, ScreenX and ScreenY properties do not crash anymore when the tray icon is hidden. They return zero instead. git-svn-id: svn://localhost/gambas/trunk@1187 867c0c6c-44f3-4631-809d-bfa615b0a4ec
