c++builder - Why can't I access the width of a THeaderSection -


i'm trying use width of headersection in theadercontrol in c++ builder xe. theadercontrol called "header" tstringgrid i'm trying align widths called "grid". in onresize event handler header, i've got following code :

void __fastcall tmainform::headerresize(tobject *sender) {     (int col=0; col<header->sections->count; col++)     {         grid->colwidths[col]=header->sections[0].width;     } }

which thought ok, won't compile.

can't seem find out how access widths of header.

also, when stuff in here compile (e.g. grid->colwidths[col]=100), headerresize event handler doesn't called (i.e. if put breakpoint in loop, run program , resize header, doesn't breakpoint).

you not accessing individual headers sections correctly. need instead:

void __fastcall tmainform::headerresize(tobject *sender) {     (int col=0; col<header->sections->count; col++)     {         grid->colwidths[col] = header->sections->items[col]->width;     } }

notice sections[col] replaced sections->items[col], , .width replaced ->width.

as onresize event not being triggered, onresize triggered when entire theadercontrol resized. when resizing individual sections, onsectionresize event triggered instead. event tells section resized, eg:

void __fastcall tmainform::headersectionresize(tcustomheadercontrol *headercontrol, theadersection *section) {     grid->colwidths[section->index] = section->width; }

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
