opengl - Using multiple textures for shader programming in Haskell -

-

i'm using textureobjects when reading in texture. read in 2 textures, , want dynamically switch between them, when try do:

tunit =(\(textureobject x) -> x) texobj

and 

activetexture $= (textureunit tunit) setuniform p "texunit" (textureunit tunit)

it doesn't work, if replace tunit 0, works it'll draw last texture load.

i'm using glutil's readtexture function load in texture.

any thoughts?

the textureunit local shader id , textureobject global texture id. wasn't binding textureobject again before setting active texture, using latest 1 bound.

qt - Change color of QGraphicsView rubber band -

i know it's possible change color of rubber band rectangle way: qrubberband rubberband = new qrubberband(qrubberband::rectangle, this); qpalette pal; pal.setbrush(qpalette::highlight, qbrush(qt::white)); rubberband->setpalette(pal); but here way achieve rubber band, rendered qgraphicsview when rubberbanddrag mode active? or in "global scope"? i'm sorry wrote question, i've looked solution long time, , nothing. few minutes after asking, found solution setting stylesheet. i'm sharing it. just go designer of qt creator, click on canvas (qgraphicsview). in "qwidget" part find "stylesheet", edit it, , put like: selection-background-color: rgba(255, 255, 255, 128); that's :-). thanks.
