help to understand XPath -

-

i have such xpath expression :

link[@rel='alternate' , @type='text/html' or not(@rel)]/@href | link/text()

?

acctually don't understand symbol |

the pipe ( | ) in xpath combines expressions. return href attribute link elements (that match predicate) , text content of links

so given fragment like

  <link>test</link>   <link href="http://www.google.com">google</link>   <link rel="zzzz" href="http://www.stackoverflow.com">stack overflow</link>

you'd get:

test http://www.google.com google stack overflow

gdi+ - WxWidgets draw a bitmap with opacity -

-
how can draw wximage, or wxbitmap dc opacity? looks not possible standard dc or wxgraphicscontext. beginlayer/endlayer not yet implemented in wxgraphicscontext have been 1 solution. gdi+ doesn't seem support layers, non-trivial add this. the solution seems to programmatically alter alpha channel pixel-by-pixel? void yourcustomwindow::onpaint( wxpaintevent& event ) { wxpaintdc dc(this); wximage image( width, height ); image.initalpha(); unsigned char* imgdata = img.getdata(); unsigned char* imgalpha = img.getalpha(); // manipulate raw memory buffers populate // them whatever image like. // putting zeros everywhere create // transparent image. // done, not quite... // wxdc can draw wxbitmaps, not wximage, // 1 last step required // wxbitmap bmp( image ); dc.drawbitmap( bmp, 0, 0 ); }
