New packages: RBC toolkit 0. Toggle navigation. New notifier. The event notifier has been completely rewritten again. It should now allow Tcl to use an external event loop like Motif's when it is embedded in other applications. No script-level interfaces have changed, but many of the C APIs have. What's new in Tk 8. Native look and feel. The widgets have been rewritten to provide nearly? Many widgets, including scrollbars, menus, and the button family, are implemented with native platform widgets.

Others, such as entries and texts, have been modified to emulate native look and feel. These changes are backwards compatible except that a some configuration options are now ignored on some platforms and b you must use the new menu mechanism described below to get native look and feel for menus.

New menus. There is a new interface for creating menus, where a menubar is implemented as a menu widget instead of a frame containing menubuttons. The -menu option for a toplevel is used to specify the name of the menubar; the menu will be displayed outside the toplevel using different mechanisms on each platform e. See the menu demos in the widget demo for examples. The old style of menus still works, but does not provide native look and feel.

Menus have several new features: New -columnbreak and -hidemargin options make it possible to create multi-column menus. It is now possible to manipulate the Apple and Help menus on the Macintosh, and the system menu on Windows. It is also possible to have a right justified Help menu on Unix. Applications can use this to generate help messages. There is a new -direction option for menubuttons, which controls where the menu pops up relative to the button.

New font mechanism. See the manual entry font. Font requests always succeed now. If the requested font is not available, Tk finds the closest available font and uses that one. Tk now supports named fonts whose precise attributes can be changed dynamically. If a named font is changed, any widget using that font updates itself to reflect the change. There is a new command font for creating named fonts and querying various information about fonts.

There are now officially supported C APIs for measuring and displaying text. If you use these APIs now, your code will automatically handle international text when internationalization is added to Tk in a future release.

See the manual entries MeasureChar. Application embedding. Embedding should be fully functional under Unix, but the implementation is incomplete on the Macintosh and PC. GIF images for them are available in several sizes in the images library subdirectory.

Use and enjoy! Tk now works correctly with Safe-Tcl: it can be loaded into safe interpreters using safe::loadTk. Text widgets now allow images to be embedded directly in the text without using embedded windows. This is more efficient and provides smoother scrolling. Buttons have a new -default option for drawing default rings in a platform-specific manner. The Macintosh now supports native bitmaps, including new builtin bitmaps stop , caution , and note , plus the ability to use bitmaps in the application's resource fork.

The destroy command now ignores windows that don't exist instead of generating an error. Incompatibilities As suggested by the change in major release number, these releases introduce some incompatibilities that affect scripts written for previous releases. The main source of incompatibilities is the new Tcl compiler. There were several places where the old Tcl semantics introduced complexity or inefficiency into the compiler, so we decided to try a few small changes to the semantics of the language to eliminate the problems.

The changes all involve obscure cases that we hope won't affect many people. The incompatibility issues raised by the compiler are described in detail in a separate document. To use one of these distributions, simply use the Tcl source command to read it into your Tcl interpreters. Note that with the Starkit distribution, you still need to source the file before invoking this command. The commands are not exported from the namespace by default.
