Hi, It's always a good idea, initialize vars like horiz_alignment and horiz_alignment, with default value. Because, function like iFlatTabsGetAlignment can fail in set value and these vars can be trash when function returns.
That's the reason what compiler emits this warning. Best.

Assunto: Re: [Iup-users] Silence gcc warning: ‘vert_alignment’ may be used uninitialized in this function Those variables are initialized 20 lines bellow in: iFlatTabsGetAlignment(alignment, &horiz_alignment, &vert_alignment); And they are not used before that. But iFlatTabsGetAlignment should initialize even in "alignment" is NULL. That was missing. Actually I did a full check on ALIGMENT attributes on all controls that use horizontalxvertical alignment options and found some minor errors too. Fixed and committed to SVN.
