javascript - Resize canvas based on number of canvas wrt to parent div -


i have viewport of dimension. currently, showing single image drawn on html5 canvas. need show multiple canvas range 1-6. requirement resize canvases based on number of canvas fits parent div.

for example : single canvas should take 100% of parent div, 2 canvas 50-50%. 6 canvas 2 rows 3 canvas each.

also, user can toggle show/hide of canvas have rearrange.

how can go doing this? using angularjs ,javascript , html5 css3.

check out css flexbox can auto-size , auto-arrange multiple canvases inside container div.

flexbox easy use after small learning curve.

declare div flexbox container:

#thediv{ display: flex; }

and tell flexbox how want canvas-items displayed:

#thediv{ flex-flow: row wrap; }

you haven't detailed how want canvases grow / shrink when container div resized or when user hides / shows canvases, flexbox has grow / shrink settings can apply canvas-items , specific canvas(s).

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
