2011-05-10Hopefully this fixes the bug Albrecht found in using fl_measure on surrogate ↵Ian MacArthur
pairs whilst we were looking at STR #2622. In summary, if you measured the string *before* the selected font had been used to actually fl_draw() anything, the measurement returned was invalid, as the new font was not "locked in" to the gc. This change makes sure the selected font is set in the gc before making the measurement. In tests, this appears to work correctly now... More opinions welcomed! git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8644 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2011-05-10Pushing this as a possible fix for STR #2622.Ian MacArthur

2011-05-01Fixed drawing artifacts when scrolling round boxes (FL_ROUND_UP_BOX andAlbrecht Schlosser
FL_ROUND_DOWN_BOX) on Linux (STR #2615). This was done by (a) setting the line width in the box drawing function (was undefined, maybe 0) (b) taking care of zero and negative line width in X11 clipping functions. Both solutions would have solved the particular problem individually. Additionally made local helper function fl_arc_i() in src/fl_round_box.cxx static to avoid name clashes. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8630 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2011-04-18OK - this time I actually think I have got it.Ian MacArthur
The win32 text-extents stuff now seems to be handling surrogate pairs correctly, at least in my testing harness, and with a variety of supplementary plane fonts. I really will leave this alone now - unless anyone finds bugs of course! I have tested for regressions and it seems to be fine AFAICT. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8605 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2011-04-17This WIN32 patch introduces a credible (though far from ideal)Ian MacArthur
workaround for text_extents being measured on glyphs from supplementary Unicode planes. It has no effect on glyphs from the Basic plane, so should not be visible at all to most code. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8600 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2011-04-17A quick hack to prevent the OSX tooltip-crash onIan MacArthur
badly formed UTF8 strings. This probably is not the best solution, but it does work. Note that the problem actually seems to be in setting the window title, and indeed if you try to label ANY window with a badly formed UTF8 string (not just a tooltip) you get the same exception thrown. NOTE: I'm not even sure why we try to set the window title in tooltips, as it is never used and the tooltip label itlsef still works fine. Anyway, we can do something better, but this will work for now. Aside: If you close an app on OSX whilst a tooltip is visible, the app will not exit, as there is still a window open (the tooltip) but no way to cancel the tooltip. Don't know if this is OSX specific or not though but it is certainly a bug. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8598 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2011-04-17I've extended Manolo's excellent tweaks that handle surrogate pairs.Ian MacArthur
I found some kind of weird interaction with some symbol fonts that covered the supplementary planes that meant we could not measure the width correctly (although we did measure the text extents correctly.) This mod mirrors what we do for non-surrogate-pair glyphs more closely and appears to do the Righ Thing now, at least for the test fonts that I have, and which were exhibiting the aberrant behaviour before. I don't think I have broken anything else in the meantime! git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8597 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2011-04-13More attempts to clean up WIN32 handling of UTF16 surrogate pairs.Ian MacArthur
In particular, I have added a new function to src/fl_utf.c called fl_ucs_to_Utf16() which converts a single 32-bit Unicode value into one (or more) UTF16 cells. This is needed in the win32 char-by-char text width() logic, and I suspect may also be useful in the OSX code in some places. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8585 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2011-04-12Under win32, text_extents() is not handling surrogate pairs either, at least ↵Ian MacArthur
on XP. The problem seems to be in GetGlyphIndicesW() which is returning invalid indices for the surrogate pairs. This causes subsequent measurements of the glyphs to fail, of course. This patch does not fix the problem, it only makes sure it fails cleanly, causing a fallback to the default fl_measure like behaviour. This is not nice, nor what I want, but at least it is consistent for now... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8582 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2011-04-12Following STR #2583, the behaviour of fl_draw_image() with d = 4 on Mac OS ↵Manolo Gouy
is here made consistent with other platforms, that is, the 4th byte of each pixel is ignored instead of treated as transparency data. In the future, the fl_draw_image() signature may be extended with another argument that would describe if and how transparency information is available. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8581 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2011-04-12Modify win32 text width(ucs) function to handle surrogate pairs.Ian MacArthur
This now correctly measures glyphs whose codepoint requires a surrogate pair to represent it in UTF16. NOTE 1: This code makes any UCS point > 0xFFFF a "special case" and measures it explicitly, rather than using the lookup table. This "explicit measure" may be slow, but actually seems OK in my tests, so far. The lookup table still covers the basic multilingual plane and is used for any glyph <= 0xFFFF as before, so the behaviour for most existing bodies of text is unchanged. This code also retains the historical behaviour under Win32 whereby strings are measured char-by-char rather than as a whole string - again this is intended to retain compatability with existing implementations. It is proposed that we should move towards measuring entire strings in the future as this is conceivably more efficient and certainly more consistent - rendering is now largely done "string as a whole" so we ought to measure in that way too; though to date the differences seem tiny, as evdienced by the text rendering page of the unittest example. NOTE 2: This does not fix the *rendering* of surrogate pairs under XP, which still seems to be broken. I suspect that TextOutW() may genuinely broken under XP, as it works fine on Vista, and it is not just my code that seems broken, other non-fltk programs exhibit the same aberrant behaviour. Measuring of surrogate pairs appears to work correctly though... Maybe we are using TextOutW() wrongly? git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8580 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2011-04-11modify the win32 text ::draw() function to do "string at once" rather than ↵Ian MacArthur
"char by char" rendering, as advised by Bill and Manolo. This seems to be good so far, though does not resolve the XP surrogate pairs issues. If this fix is bad, we need to revert to r8577, which is good... And I still haven't fixed the handling of width in win32 code, so it is still inconsistent with draw for high Ubicode points. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@8579 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
