Dear Haskellers, I am pleased to announce HToolkit 1.2 for Haskell. The HToolkit is a platform independent package for Graphical User Interface. The package is split into two libraries GIO and Port. The Port is a low-level Haskell 98+FFI compatible API, while GIO is a high-level user friendly interface to Port. The current release supports all Windows based platforms and Linux/Unix platforms with GTK/GNOME toolkit. There are many new features and many bugfixes. The 1.2 release is a source incompatible with 1.0 release. Home page ~~~~~~~~~ http://htoolkit.sourceforge.net Incompatible changes: ~~~~~~~~~~~~~~~~~~~~~ 1. There is a new API for creating: - radio menu items (MenuRadioItem) - check boxes (CheckBox) - radio buttons (RadioBox) In the new API each widget is created idependently from the other widgets and after that they are linked together to form a group of related items. 2. The 'drawInWidget' function is renamed to 'paintIn' and the 'drawInBitmap' is renamed to 'paintInBitmap'. 3. The 'dialogFont' function is removed. Both windows and dialogs now use the same font (returned from the 'defaultFont' function). 4. The 'defaultFont', 'defaultFontDef', 'dialogColor', 'windowColor' and 'textColor' functions now return values which are system dependent. The returned values are given from the current theme selected in Windows/GNOME. 5. The 'itemCount' attribute of Menu is removed. There is a new 'count' attribute which is defined in the type class and instances are defined for Popup, ListBox, Notebook, Menu and ToolBar types. 6. The 'visible' attribute of Entry is renamed to 'password'. 7. The windows and the dialogs are created invisible by default and can be shown with the 'showWindow' or 'runDialog' (for dialogs) functions. New features ~~~~~~~~~~~~ 1. The implementation for the ToolBar is completed. Unfortunatelly in this release the toolbars for Linux don't work. The reason is that the CVS version of Port uses GTK 2.3. 2. Each window and dialog can be shown/hidden with the 'showWindow' and 'hideWindow' functions or by changing the value of the new attribute 'visible'. The attribute is read/write and its current value determines whether the window is visible. The windows and the dialogs are created invisible by default and can be shown with the 'showWindow' or 'runDialog' (for dialogs) functions. 4. In HToolkit 1.0 when the dialog size becomes smaller than the minimal size required to layout the controls, the dialog automatically shows scrollers. In HToolkit 1.2 the dialogs cannot be shrinked to a size smaller than the minimal. Under Windows a size gripper is drawn at the righthand bottom corner of the resizable dialogs just like the modern resizable dialogs under Windows. 5. The controls are created invisible by default and are shown only if they are included in the layout expression of their parent. In this way it is possible to dynamically hide/show and rearrange the controls. 6.Three new controls are added: Notebook, GroupBox and CompoundControl. The CompoundControl is a container for other controls with automatic scrollbars. The control supports 'mouse', 'keyboard' and 'paint' events just like the toplevel windows and dialogs. The primary purpose of CompoundControl is to create new custom controls. 7. The layout algorithm is extended with 'stretch', 'hstretch' and 'vstretch' functions in addition to 'fill', 'hfill' and 'vfill'. The new functions stretch only the specified control to fit the entire space without affecting the rest controls in the table. Cheers, Krasimir __________________________________ Do you Yahoo!?
