Version: 1.3.2
Attaching a test program, when.cxx, to test the when() behavior
of tabs vs. radio buttons vs. hold + multi browser.
Also, used this program to generate this table of when() behavior
which will be useful for perhaps fixing not only Fl_Tabs, but bugs
in existing widgets:
http://seriss.com/people/erco/fltk/when-behavior-03-26-2013.html
This test should probably be integrated into the unittests
to check the when() behavior of all widgets. (Instead of using
the tty, the unittest could probably pop open an Fl_Text_Display
widget on first callback, and scroll realtime callback msgs in that)

Re: [fltk.development] RFC: Adding when() support in Fl_Tabs
So here's a big table comparing the when() behavior of radio and browser, comparing mouse clicks and keyboard nav clicks: http://seriss.com/people/erco/fltk/when-behavior-03-26-2013.html Fixed that table up a bit to make it easier to read. Hit Reload to see the changes. During testing I noticed some inconsistencies with changed()'s value, so started adding that to the table too. ___ fltk-dev mailing list fltk-dev@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev
Re: [fltk.development] [RFE] STR #2941: RFE: fl_text_extents(): support multiple lines
DO NOT REPLY TO THIS MESSAGE. INSTEAD, POST ANY RESPONSES TO THE LINK BELOW. [STR New] Link: http://www.fltk.org/str.php?L2941 Version: 1.3-feature This may be possible, but I didn't do it (thinking about it was making my head hurt...) I guess the idea is to use the typographical height of the folded string, which will take into account the vertical leading between rows of text and so forth; but tailor that to take account of the inked height of the first and last rows... Or something... In any case, I think we'd maybe want to make that a distinct function from fl_text_extents() if we did that ? I also wonder about (somehow) handling fltk @ symbol expansion and so forth in the improved mechanism. If we go that way...

DO NOT REPLY TO THIS MESSAGE. INSTEAD, POST ANY RESPONSES TO THE LINK BELOW. [STR New] Link: http://www.fltk.org/str.php?L2941 Version: 1.3-feature Based on fl_measure(), I'd say symbol support isn't hard. The symbols simply scale to the current string height, whatever it is. So if it's a single line, it's exactly fl_height(). If it's multiple lines, it scales to the fl_height() x #lines. The new code I intend to replace fl_measure()'s with will probably be good reference for that. Perhaps I should make it a function that returns the (potentially two) symbol sizes. The symbol size calculations in fl_measure() appear to assume symbols are square, which makes computation easy. Apparently symbol scaling (e.g. @+9- and @-9-) doesn't affect fl_measure() calculations, so I guess it just over-draws or under-draws when the user supplies that in a string.

[STR New] Link: http://www.fltk.org/str.php?L2941 Version: 1.3-feature symbols simply scale to the current string height, whatever it is. I should add fltk's @ symbols are not really like characters, they're more like graphics that fill the left and right margins. See this screenshot, esp. see the last example for the behavior of @ symbols in a multiline string: http://www.fltk.org/strfiles/2940/symbol-examples.png I never knew it worked that way; want to add that to the docs, which is what STR# 2940 covers.

Sure you can distribute it. It is there in the main page, what version to download. I don't know anything about 2.x, but indeed it looks like the tar balls are no longer in the download section.. don't know why. You should be able to still access 2.x from SVN; see the instructions under Subversion Access on the downloads page, eg: svn co http://svn.easysw.com/public/fltk/fltk/trunk fltk-2.0 I just checked it out; the last commit was on Mar 2012. Seems to build OK for me, on centos 5.6 at least. You mentioned the trunk doesn't build.. try a fresh checkout. If that doesn't work, what platform and what errors? Not sure I or anyone can advise, all I know is all active alpha dev on 2.x has been redirected to 3.x ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
