[Libreoffice] [PUSHED] GTK+ integration

[Michael Meeks]

Hi there,

	Firstly - nice work - this looks promising, and sorry for the delay,
things have been busy today with the 3.3.0 release.

	Soo ... :-) I had a few comments / queries.

	Interesting; it might be nice to capture the type that is, we already
have a:

        ((nType == CTRL_MENUBAR) &&
                (   (nPart==PART_ENTIRE_CONTROL) )              )   ||

	in IsNativeControlSupported, can we just add another nPart to it, as in
the other options ?

	Right; so - this was a fix for a crasher [ incidentally we should
prolly dig out similar obsolete fixes in this code ]. Since it affects
only the 5 year old Fedora Core 4 (that we know) with crux theme - I
added a check like this:

@@ -2731,9 +2731,10 @@ BOOL GtkSalGraphics::NWPaintGTKPopupMenu(
             const OUString& )
 {
     // #i50745# gtk does not draw disabled menu entries (and crux theme
-    // even crashes), draw them using vcl functionality.
-    if( nPart == PART_MENU_ITEM && ! (nState & CTRL_STATE_ENABLED) )
-        return FALSE;
+    // even crashes) in very old (Fedora Core 4 vintage) gtk's
+    if (gtk_major_version <= 2 && gtk_minor_version <= 8 &&
+        nPart == PART_MENU_ITEM && ! (nState & CTRL_STATE_ENABLED) )
+        return TRUE;
 
	Hopefully it does what we want and mitigates the risk :-)

	That is fine.

	Hmm, that makes some sense - but it still concerns me ;-) I hope you
know what you're doing.

	I've pushed it - thanks so much ! if you're in that neck of the woods -
do you test with larger theme font sizes ? :-) (cf. my attached
toolbar ).

	Also - I assume your changes are under the LGPLv3+/MPL combination we
recommend - can you confirm that ! oh, and if you could close the bug
that'd be great too :-)

	Looking forward to seeing what you get up to next,

	Many thanks !

		Michael.
