Tk Source Code

With a decimal comma "0.5" was read as 0, so the up button gave 0.1 instead of 0.6 and -from/-to clamped valid values. Use Tcl_GetDouble() instead, as for the -from, -to and -increment options. Same for the value reported to AT-SPI. check-in: a13d8dba user: serhiy.storchaka tags: spinbox-locale-parse, core-spinbox-locale-parse

Also send the EWMH _NET_RESTACK_WINDOW request, which KWin and Mutter honor for a window which is not active, while they ignore the plain XReconfigureWMWindow request. It restacks without activating the window. leaf check-in: 75327235 user: serhiy.storchaka tags: x11-raise-ewmh, core-x11-raise-ewmh

The window manager never gives the focus to an override-redirect window, and Tk refused to set the X focus to it even with "focus -force" (an old olvwm workaround for menus), so "focus" reported the window while key events went elsewhere. "focus -force" now works for such windows on X11. check-in: 98ea86d9 user: serhiy.storchaka tags: x11-override-redirect-focus

With input methods disabled, TkpGetKeySym() ignored Num Lock and reported KP_Left for keypad 4. Select the keypad keysym with Num Lock as XLookupString() does. check-in: 27ce67ba user: serhiy.storchaka tags: x11-keypad-numlock, core-x11-keypad-numlock

The font set for the preedit area of an over-the-spot input method is now chosen by the pixel size of the widget's line height, reported by Tk_SetCaretPos(), and cached per display. Also do not create the default font set again when the input method is reopened. leaf check-in: c125ceaa user: serhiy.storchaka tags: x11-xim-preedit-font, core-x11-xim-preedit-font

The X server sends a KeyRelease/KeyPress pair for each auto-repeat unless the client enables detectable auto-repeat. Now a held key generates repeated KeyPress events and a single KeyRelease, as on Windows and macOS. leaf check-in: 6d0c31fd user: serhiy.storchaka tags: x11-detectable-autorepeat, core-x11-detectable-autorepeat

Some window managers (Mutter) keep a minimized window mapped and only set _NET_WM_STATE_HIDDEN. Now "wm state" reports "iconic" for such a window, and "wm deiconify" sends a _NET_ACTIVE_WINDOW request to unminimize it. leaf check-in: 144bb549 user: serhiy.storchaka tags: x11-wm-hidden-state, core-x11-wm-hidden-state

TkpWmSetState() did not clear the withdrawn flag when iconifying a window which has not been mapped yet. leaf check-in: 43c68112 user: serhiy.storchaka tags: x11-wm-state-iconic, core-x11-wm-state-iconic

libnotify registers GObject types, which cannot be unregistered, so it cannot be loaded again after unloading. Keep it loaded for the lifetime of the process. check-in: dc39bb00 user: serhiy.storchaka tags: sysnotify-no-unload, core-sysnotify-no-unload

Use the XRandR extension, if available, to be notified of changes of the screen size and to update the size recorded by Xlib. The size in millimeters is scaled with it, so that [tk scaling] does not change. leaf check-in: ae3b099b user: serhiy.storchaka tags: core-x11-randr-screen-size, x11-randr-screen-size

With a core-font (non-Xft) build, IdentifySymbolEncodings() crashed on a font whose XLFD family is a wildcard such as "????", which TkFontParseXLFD() leaves NULL. leaf check-in: 70fa3ec2 user: serhiy.storchaka tags: bug-2236352, core-bug-2236352

TkpGetKeySym() used the keymap of the first XKB group only, so with input methods off %K was the Latin letter of the key whatever the current layout. Now the group of the event is used.

With a non-Latin layout, bindings like <Alt-q> never matched. Now, if Control or Alt is down, the keysym of the key in a Latin layout is used, as other X11 toolkits do. Typed characters (%A) are not affected. check-in: b052917b user: serhiy.storchaka tags: x11-nonlatin-shortcuts

An image of N x M pixels with density d is laid out and drawn as N/d x M/d screen pixels: on Aqua its pixels then map one to one onto the Retina backing store instead of being stretched, X11 and Windows resample it in software. Nothing changes at density 1. check-in: 06f7f96c user: nab tags: nab-photo-density
