Tk Source Code

Backport of [880f8c8d59] from 9.0 and 9.1. A pane in a hidden notebook tab is unmapped, so its geometry request was taken as the initial request of a pane which is not shown yet, and it overwrote the sash position. The new Ttk_ContentIsMapped() tells whether the pane has been placed, which does not change while the panedwindow itself is unmapped. Test paned-unmapped-1. check-in: 0b59d9cd user: serhiy.storchaka tags: core-8-6-branch

Backport of [87fa518cee] from 9.0 and 9.1: the SIGINT, SIGHUP and SIGTERM handlers are only installed if the application which embeds Tk has not installed its own (e.g. Python raises KeyboardInterrupt from its SIGINT handler). check-in: c505fe41 user: serhiy.storchaka tags: core-8-6-branch

Backport of the fixes from 9.0 and 9.1.

A WM_KEYDOWN message with VK_PACKET, sent for a character entered via an input method or the touch keyboard, was re-posted with the character as the virtual key code, so the KeyPress event had the keysym of a function key. Now no events are generated for the VK_PACKET key itself; the WM_CHAR message produced by TranslateMessage() generates the key events.

GetTranslatedKey() retrieved the WM_CHAR messages with GetMessageA(), so Windows converted the characters to the code page of the keyboard layout, and TkpGetString() decoded them with a code page guessed from the input language. When the two differed, the typed characters were mangled. Now the messages are retrieved as Unicode and the characters are stored as UTF-8 in the key event, and the code page machinery is removed.

Tests event-8.4, event-8.5 and event-8.6, and the missing testsendinput constraint. check-in: 4a7d6f6b user: serhiy.storchaka tags: core-8-6-branch

Port [c289f69486] from core-8-6-branch: frame, toplevel and labelframe crashed when the last option had no value. Add tests. check-in: d938d1b9 user: jan.nijtmans tags: core-9-0-branch

With a Cyrillic or other non-Latin layout, TkpGetKeySym() returned the character of the key as the keysym for Ctrl+key and Alt+key. It is not a valid keysym, so bindings like <Control-c> and <Alt-x> never matched. Now the Latin letter or digit of the virtual key code is used, as other Windows applications do. Typed characters (%A) are not affected. check-in: 3eafc907 user: serhiy.storchaka tags: win-nonlatin-shortcuts

"Show desktop" minimizes windows without WM_SYSCOMMAND, and SC_RESTORE was ignored for windows outside the grab tree, so the main window could not be restored from the taskbar, and neither could the modal dialog owned by it. closed check-in: 2838273d user: serhiy.storchaka tags: win-grab-restore

On Windows long is 32-bit, so the unsigned 32-bit GetTickCount()-li.dwTime delta in Tk_GetUserInactiveTime() was returned as a negative number for inactivity of 2**31 ms or more. Clamp to 0x7fffffff.
