(B> Hello,
(B>
(B> I've been playing with the textblock in relation to EWL a bit lately and have
(Brun into an issue. In the textblock, until you evas_object_resize, the width is
(Balways 0 (I consistently seem to get height 3 back for some reason).
(B
(Bthats due to it accounting for space for a double-underline if it were to appear
(Bon the last line - it doesn't remove the extra if there is no underline on the
(Blast line of the textblock :) that 3 would be a bug. what you want is the call
(Bthat gets the native size (how big it would be without any wrapping/avoiding of
(Bobstacles etc.) but that call isnt done yet (not the FIXME's in the code) :)
(B
(Banyway - the reason for this is you are getting the formatted size. that is the
(Bsize post-formatting which relies on the object width to know when to line wrap
(Band thus cannot compute a size until it at least has a width :) if the width is
(B0 at the start.. it cant exactly fit much text into a 0 width object...
(Bcurrently thats another fixme.. what if a word or char doesnt even fit in the
(Bobject width. currently it blindly skips on when that happens...
(B
(B> Now, the problem with EWL is that it wants to get the size of the formatted
(Bregion and then resize/set its preferred size to that size. Now, Nathan has a
(Bworkaround:
(B>
(B> <RbdPngn> ok, so here's teh work around to discover preferred size
(B> <RbdPngn> fill in your text to the textblock
(B> <RbdPngn> resize the object to a starting size, probably start small
(B> <RbdPngn> resize and query the y position of the end of the text
(B> <RbdPngn> repeat until y doesn't change
(B
(Bthats evil! :) how about waiting till the native size format is set. :)
(B
(B> But, I don't think this will work for scrollpane.
(B
(Bif its text WITHIN the scrollpane then you only really care about its height, so
(Bmake the width the scrollpane internal width and u can query the formatted
(Bheight to then resize to that height and set scrollbar sizes accordingly.
(B
(B> Is there a way we could say, what is the formatted size of this
(Bevas_object_textblock using the longest line as the evas object width?
(B
(Byes.. the native size get call - which is... not done yet :)
