  • make sure the last line of text layouts include leading

  • documentation notes:

    • static binaries do not link system libraries, meaning apps still depend on shared GTK+, etc.
    • ui*Buttons are NOT compatible with uiButton functions
  • more robust layout handling

    • uiFormTie() for ensuring multiple uiForms have the same label area widths
    • uiSizeGroup for size groups (GtkSizeGroup on GTK+, auto layout constraints on OS X; consider adding after 10.8 is gone)
  • windows: should the initial hwndInsertAfter be HWND_BOTTOM for what we want?

  • windows: document the rules for controls and containers

  • windows: document the minimum size change propagation system

  • provisions for controls that cannot be grown? especiailly for windows

  • LC_VERSION_MIN_MACOSX has the 10.11 SDK; see if we can knock it down to 10.8 too; OS version is fine

    • apply the OS version stuff to the test program and examples too
    • what about micro versions (10.8.x)? force 10.8.0?
  • go through ALL the objective-c objects we create and make sure we are using the proper ownership (alloc/init and new are owned by us, all class method constructors are autoreleased - thanks mikeash)

  • on OS X, edit shortcuts like command-C working require that the menu entries be defined, or so it seems, even for NSAlert

    • other platforms?
  • make sure all OS X event handlers that use target-action set the action to NULL when the target is unset

  • provide a way to get the currently selected uiTab page? set?

  • make it so that the windows cntrols only register a resize if their new minimum size is larger than their current size to easen the effect of flicker

    • it won't remove that outright, but it'll help
  • add an option to the test program to run page7b as an independent test in its own window

    • same for page7c
  • http://blogs.msdn.com/b/oldnewthing/archive/2004/01/12/57833.aspx provide a DEF file on Windows

  • all ports: update state when adding a control to a parent

  • should uiWindowsSizing be computed against the window handle, not the parent?

  • DPI awareness on windows

  • http://stackoverflow.com/questions/4543087/applicationwillterminate-and-the-dock-but-wanting-to-cancel-this-action

ultimately:

  • MAYBE readd lifetime handling/destruction blocking

  • related? [12:25] And the blue outline on those buttons [ALL clicked buttons on Windows 7] won't go away

    • I get this too
      • not anymore
  • SWP_NOCOPYBITS to avoid button redraw issues on Windows when not in tab, but only when making resize faster

  • secondary side alignment control in uiBox

  • Windows: don't abort if a cleanup function fails?

  • 32-bit Mac OS X support (requires lots of code changes)

    • change the build system to be more receptive to arch changes

notes to self

  • explicitly document label position at top-left corner

  • explicitly document that if number of radio buttons >= 1 there will always be a selection

  • mark that uiControlShow() on a uiWindow() will bring to front and give keyboard focus because of OS X

    • make sure ShowWindow() is sufficient for zorder on Windows
  • document that you CAN use InsertAt functions to insert at the first invalid index, even if the array is empty

  • note that uiTabInsertAt() does NOT change the current tab page (it may change its index if inserting before the current page)

  • note that the default action for uiWindowOnClosing() is to return 0 (keep the window open)

  • note that uiInitOptions should be initialized to zero

  • explicitly document that uiCheckboxSetChecked() and uiEntrySetText() do not fire uiCheckboxOnToggled() and uiEntryOnChanged(), respectively

  • note that if a menu is requested on systems with menubars on windows but no menus are defined, the result is a blank menubar, with whatever that means left up to the OS to decide

  • note that handling of multiple consecutive separators in menus, leading separators in menus, and trailing separators in menus are all OS-defined

  • note that uiDrawMatrixInvert() does not change the matrix if it fails

  • note that the use of strings that are not strictly valid UTF-8 results in undefined behavior

  • test RTL

    • automate RTL
  • now that stock items are deprecated, I have to maintain translations of the Cancel, Open, and Save buttons on GTK+ myself (thanks baedert in irc.gimp.net/#gtk+)

    • either that or keep using stock items
  • http://blogs.msdn.com/b/oldnewthing/archive/2014/02/26/10503148.aspx

  • build optimizations

  • use http://www.appveyor.com/ to do Windows build CI since people want CI

  • consider just having the windows backend in C++

    • consider having it all in C++

don't forget LONGTERMs as well

notes

  • http://blogs.msdn.com/b/oldnewthing/archive/2004/03/29/101121.aspx on accelerators

  • group and tab should act as if they have no child if the child is hidden on windows

  • a way to do recursive main loops

    • how do we handle 0 returns from non-recursive uiMainStep() calls that aren't the main loop? (event handlers, for instance)
  • should repeated calls to uiMainStep() after uiQuit() return 0 reliably? this will be needed for non-recursive loops

[01:41:47] Hi. does pango support "fgalpha". I see that foreground="112233xx" works ( alpha=xx ), but fgalpha is a no-op [01:52:29] pango_attr_foreground_alpha_new (32767) seems to be called in either case, but only the "foreground" attr works [01:56:09] lolek (lolek@ip-91-244-230-76.simant.pl) joined the channel [01:57:48] ok. seems like "foreground" is mandatory attr, 1. "foreground-without-alpha" + "alpha" works 2. "foreground-with-alpha" works. 3. "alpha" alone doesn [01:57:52] 't work [01:58:29] Is there a way to just specify alpha on the current foreground color ? [02:00:23] lolek (lolek@ip-91-244-230-76.simant.pl) left the channel [02:07:41] mjog (mjog@uniwide-pat-pool-129-94-8-98.gw.unsw.edu.au) left IRC (Quit: mjog) [02:08:10] seb128 (seb128@53542B83.cm-6-5a.dynamic.ziggo.nl) joined the channel [02:12:37] huh [02:12:41] what version of pango? [02:13:05] the latest . [02:15:00] 1.40.3 [02:20:46] I'll ahve to keep this in mind then, thanks [02:20:59] if only there was a cairo-specific attribute for alpha...

FONT LOADING

[00:10:08] andlabs: is there API yet to load from memory? last i checked i only found from file (which we use in builder). https://git.gnome.org/browse/gnome-builder/tree/libide/editor/ide-editor-map-bin.c#n115 [00:13:12] mrmcq2u_ (mrmcq2u@109.79.53.90) joined the channel [00:14:59] mrmcq2u (mrmcq2u@109.79.73.102) left IRC (Ping timeout: 181 seconds) [00:15:19] hergertme: no, which is why I was asking =P [00:15:30] I would have dug down if I could ensure at least something about the backends a GTK+ 3 program uses [00:15:39] on all platforms except windows and os x [00:16:11] to the best of my (partially outdated, given pace of foss) knowledge there isn't an api to load from memory [00:16:28] you can possibly make a tmpdir and put a temp file in there [00:16:52] and load that as your font dir in your FcConfig, so any PangoFontDescription would point to that one font, no matter what [00:17:18] (using the API layed out in that link) [00:18:18] dsr1014__ (dsr1014@c-73-72-102-18.hsd1.il.comcast.net) joined the channel [00:35:18] simukis_ (simukis@78-60-58-6.static.zebra.lt) left IRC (Quit: simukis_) [00:35:48] dreamon_ (dreamon@ppp-188-174-49-41.dynamic.mnet-online.de) joined the channel [00:40:09] samtoday_ (samtoday@114-198-116-132.dyn.iinet.net.au) joined the channel [00:40:32] mjog (mjog@120.18.225.46) joined the channel [00:40:38] hergertme: not necessarily fontconfig [00:40:45] it can be with ft2 or xft I guess [00:40:55] especially since I want the API NOT to make the font part of the font panel [00:42:07] what sort of deprecated code are you trying to support? [00:42:35] both of those are deprecated in pango fwiw [00:43:06] on Linux im pretty sure we use FC everywhere these days [00:44:46] (and gtk_widget_set_font_map() is how you get your custom font into a widget without affecting the global font lists, as layed out in that link) [00:49:14] vasaikar (vasaikar@125.16.97.121) joined the channel [00:50:14] karlt (karl@2400:e780:801:224:f121:e611:d139:e70e) left IRC (Client exited) [00:50:49] karlt (karl@2400:e780:801:224:f121:e611:d139:e70e) joined the channel [00:51:43] PioneerAxon (PioneerAxo@122.171.61.146) left IRC (Ping timeout: 180 seconds) [00:57:47] PioneerAxon (PioneerAxo@106.201.37.181) joined the channel [01:03:01] karlt (karl@2400:e780:801:224:f121:e611:d139:e70e) left IRC (Ping timeout: 181 seconds) [01:05:49] muhannad (muhannad@95.218.26.152) left IRC (Quit: muhannad) [01:07:51] hergertme: hm [01:07:54] all right, thanks [01:08:05] hergertme: fwiw right now my requirement is 3.10 [01:10:47] ah, well you'll probably be missing the neccesary font API on gtk_widget [01:11:04] but pango should be fine even back as far as https://developer.gnome.org/pango/1.28/PangoFcFontMap.html [01:11:56] good [01:12:04] because this is for custom drawing into a DrawingArea [01:14:12] presumably just create your PangoContext as normal, but call pango_context_set_font_map() with the map you've setup. now, the load a font from a file i dont think was added to FontConfig until later though (not sure what release) [01:15:53] FcConfigAppFontAddFile() <-- that API [01:16:30] great, and they don't say what version the API was added in teh docs function: ide_editor_map_bin_add()
