This is an alpha release, meaning that +the feature set and API have not yet stabilized. + +Here is what's new in this release: + +. CFFI snapshot 060606 or later is required in order to benefit from a +bugfix for a problem when running on LispWorks where foreign structure +contents could be corrupted; the most obvious symptom of this was a +Win32 error encountered when attempting to create a window. + +. A new layout manager called `heap-layout' has been implemented. Its +purpose is to align all the children of a container in a single +Z-orderwise stack and allow the application to select which of the +children are top-most at any given time. This is useful when +implemnenting windows with panels containing related functionality, +where only one such panel should be visible at a time (e.g., property +sheets or wizard dialogs). + +. This release provides access to the standard font dialog, and +integrates with the previously-defined font and font-data classes. + +. Application-defined modal and modeless dialogs are now fully +supported, including keyboard navigation (tab traversal, default +button invocation via the ENTER key, and cancel button invocation via +the ESC key). + +. In this release, the flow-layout manager gets a new style called +:normalize which instructs the manager to size children equally using +the maximum dimension of the children's preferred sizes opposite to +the dimension in which the layout is oriented. + +. Applications may set minimum size and/or maximum size constraints +for top-level windows. Setting both constraints to the same size +implicitly disables resizing by the user. + +. It is also possible to explicitly disable resizabilty, which not +only results in a fixed window size but also causes window decorations +to be updated appropriately (no maximize box and no resize handles in +the window frame). + +. The button class has been expanded to support checkboxes, radio +buttons, toggle buttons, and tri-state button controls. + +. There is now basic support for instantiating single-line and +multi-line edit controls. Edit controls participate in the focus gain +/ focus loss protocol; they also provide notification when contents +change via the event-modify generic function. + +. Implemented event-focus-gain and event-focus-loss to allow applications +to response to changes in focus. + +. It is now possible to customize the background color, foreground +color, and font of label controls. Infrastructure to support similar +customizations for other controls is in place. + +. Functions capture-mouse and release-mouse are available to implement +mouse capturing behavior. + +. Added a function to programmatically append separators to menus; +this was already possible via DEFMENU but not yet supported for +dynamic menu management. + +. Rewrote timer event processing such that the library no longer uses +the TimerProc callback technique, but instead each call to the Win32 +SetTimer function is made with the handle to a hidden utility window +managed by the library code. + +. Changed the rectangle type to be a structure; it was a class before. + +. Started work on infrastructure required to support a new layout +manager called `group-layout' which will appear in a subsequent +release. The infrastructure developed this time includes definition of +a text-baseline method that widgets implement to help layout managers +align text appropriately. + +. Also started work on infrastructure needed to enable WinXP-themed +controls. + +. Continued work on the UnBlocked demo game. + +The above list is in addition to documentation enhancements and +bug fixes. The README.txt file in the release zip file also has +additional important information about this release. + +Download the release zip file here: +http://prdownloads.sourceforge.net/graphic-forms/graphic-forms-0.4.0.zip?download + +The project website is: +http://common-lisp.net/project/graphic-forms/ + +Jack Unrue +jdunrue (at) gmail (dot) com +July 3rd 2006 + +============================================================================== Modified: trunk/README.txt ============================================================================== --- trunk/README.txt (original) +++ trunk/README.txt Mon Jul 3 19:22:32 2006 @@ -18,7 +18,7 @@ - Cells http://common-lisp.net/project/cells/ - - CFFI 0.9.0 + - CFFI (cffi-060606 or later) http://common-lisp.net/project/cffi/ - lw-compat @@ -62,9 +62,9 @@ display properly, expecially when a transparency is selected. 3.
