Tk Source Code

* generic/tkImgPNG.c (ReadIDAT, DecodePNG): Move the check for overall termination of the compressed stream until after the final IDAT has been read, so that multi-segment images will work right. Reported by Andy Goth on the Wiki.

* generic/tkImgPNG.c (WriteIDAT): [Bug 2984787]: Use the correct flushing semantics when handling the last data from the image. Without this, many PNG readers (notably including Firefox) refuse to show the image and instead complain about errors. (ReadIDAT): Added sanity checks to ensure that when we've got bad data of the sorts of forms we were previously generating, we detect it and error out rather than silently failing. (WriteExtraChunks): New function to write in some basic metadata.

* generic/tkImgPhoto.c (ImgPhotoCmd): [Bug 2983824]: Use the file extension to guess the output format to use if one isn't specified.

* unix/tkUnixRFont.c (GetFont): [Bug 2978410]: Do not use non-constant initializers for structures, since HP-UX cc doesn't like it.

* unix/configure.in, unix/Makefile.in: [Bug 2965133]: Get rid of the spurious NONE and some pointless quotes that were causing problems with building Tk on OSX. Overall bug might not yet be solved.

* library/entry.tcl: [Bug 2971663]: Make the <Up> and <Down> keys * library/ttk/entry.tcl: explicitly do nothing, since Tk-on-Cocoa will generate (invisible zero-width) characters for them otherwise. The explicitly empty bindings are harmless on other platforms.

* generic/tkText.c (DumpLine): [Bug 2968379]: When peers are about, there can be unnamed marks present during a dump. Ignore them as they will just be for the peers' insert and current marks, which aren't very important.

* generic/tkPlatDecls.h: Correct broken 2886635 fix. [Bug 2965600]

When the pointer moves to another entry from a cascade entry the sub-menu should popdown. This is how other menus on X11 work today. This effect will not be used if the user has configured ClickToFocus to maintain the previous Tk menu effects. check-in: 97932211 user: patthoyts tags: trunk

Modern unix window managers use a set of window properties to give hints as to the purpose of a toplevel window. They then use these hints to apply various animation and decoration options based on the type (dialog, menu, tooltip and more).

This patch adds a [wm attributes $w -type] option to control and read the type hint and makes use of this for the ttk::combobox and the dialogs raised from the Tk library scripts.

Tk is the only toolkit to continue the Motif scheme of anchoring a Help menu to the extreme right of the menubar. This patch disables the special handling of the .help menu so that the help menu will be grouped with the other menu items as is common with other toolkits.

The old behaviour can be restored by setting the option *Menu.useMotifHelp to true or by calling 'tk::classic::restore menu'.

This patch makes Tk menus on unix follow mouse motion in the same way Windows and GNOME menus follow the mouse. Once a menubar dropdown has been activated, moving the mouse to another menubar button or cascade item will activate the dropdown without needing another click.

The previous behaviour can be restored by setting the *Menu.clickToFocus option true or by calling 'tk::classic::restore menu' if this is preferred.

Multiple edits have peverted the original meaning of the phrase 'image file data' to reference a filename option that does not exist. check-in: ef621874 user: patthoyts tags: trunk

The standard for Windows and Gtk+ is that the <Return> binding invokes the button that currently has the keyboard focus. This can be seen in tk_messageBox which implements this. This patch implements this feature and also makes use of the tk grab utility functions to replace the grab handling code. check-in: 8f0a215f user: patthoyts tags: trunk

This patch by Anton Kovalenko adds support for the Windows system-wide UI setting that prevents accelerators being underlined unless the Alt key is pressed.

Modified to support the system keyboard cues flag and to handle dynamic changes to the system parameters by the user. check-in: 1f427626 user: patthoyts tags: trunk

The torn-off menu entries do not activate except immediately over the label or icon. If the window containing the torn-off menu is expanded then a lot of dead space may be created, including the cascade arrow. This patch fixes this making the whole width for any menu entry capable of activation when the pointer hovers over the item. check-in: c613aa58 user: patthoyts tags: trunk

* generic/tkConfig.c: Added another dimension of refCounting to the * generic/tkInt.c: "option" Tcl_ObjType to improve memory troubles * generic/tkObj.c: detailed in [Bug 2492179]. Also removed registration of the "option" Tcl_ObjType. *** POTENTIAL INCOMPATIBILITY *** for callers of Tcl_GetObjType("option") which must now handle a NULL return.

+ Where possible, replace [a; update; b] with [a ; after 0 b]. + Where not possible, use [update idletasks] instead of full [update]. + Use [after 0] in favor of [after idle] for delayed work, to reduce likelihood of reentrancy issues in [update idletasks]. check-in: fca757cb user: jenglish tags: trunk

* unix/configure: autoconf-2.59

If a checkbutton offvalue is the same as the tristate value we should use the off state in preference. (andrey gusev)

Vista and Windows 7 like to display larger icon sizes than previous versions although we do not include the largest suggested size (256x256) as that prevents building with msvc6. Both icons are rendered from SVG versions of the Tcl feather or the Wish lamp.

This ensures the icon can be drawn properly on various colour depth surfaces - in particular it fixes a problem with remote desktop and looks better in the vista task switching overlay. (cjmcdonald)
