when using iwidgets::panedwindow couldn't rid of margins between panes , sashes (shown in blue arrows in small picture). there way rid of them, pane next sash, in ttk::panedwindow?

looking through documentation link to, i'd estimate problem mix of default -margin on panes create (8 pixels, according documentation) , -sashwidth , -thickness overall widget options (which default 10 , 3 pixels, respectively).

you can either set -margin @ creation time or update paneconfigure method (which missing documentation, shown in example in documentation), , -sashwidth , -thickness options set either @ widget creation time or via configure method (as per standard pattern of tk widgets).

setting options mentioned above 0 unlikely produce usable widget, pane margins can reduced 0 without ill effect (they describe space between interior widget , edges of pane).

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
