FAQ react-virtualized questions -


i attempting make grid polished. instead of asking these questions separately, thought gather them altogether in 1 place.

for react-virtualized grid, how i:

  • render decimals precision 2 , trailing zeroes 48.5 shows 48.50.
  • put lines in between rows , lines in between columns.
  • add column names header @ top of grid.
  • change font of text in cell
  • change alignment per cell

cellrenderer looks this:

cellrenderer ({ columnindex, key, rowindex, style }) {     const { quotelist } = this.state;     const rowclass = this.getrowclassname(rowindex)      // first try @ making use of .css customize look. doesn't seen anything.     const classnames = cn(rowclass, styles.cell, {       [styles.centeredcell]: columnindex > 1     })      return (         <div //classname={classnames}           key={key}           style={style}          >           {quotelist[rowindex][columnindex]}         </div>     )     }

i instantiating grid this:

render() { return (         <div style={{ textalign: "center" }}>         <grid             ref={(ref) => this.thegrid = ref}             cellrenderer={this.cellrenderer}             columncount={7}             columnwidth={75}             height={quotelist.length * 20}             rowcount={quotelist.length}             rowheight={20}             width={800}         />           </div>       ); }

i see in 1 of examples .css file looks this, not sure how apply them [note try inside cellrenderer].

.gridrow {   margin-top: 15px;   display: flex;   flex-direction: row; } .gridcolumn {   display: flex;   flex-direction: column;   flex: 1 1 auto; } .leftsidegridcontainer {   flex: 0 0 50px; }  .bodygrid {   width: 100%;   border: 1px solid #e0e0e0; }  .evenrow, .oddrow {   border-bottom: 1px solid #e0e0e0; } .oddrow {   background-color: #fafafa; }  .cell, .headercell {   width: 100%;   height: 100%;   display: flex;   flex-direction: column;   justify-content: center;   padding: 0 .5em; } .cell {   border-right: 1px solid #e0e0e0;   border-bottom: 1px solid #e0e0e0; } .headercell {   font-weight: bold;   border-right: 1px solid #ccc;   background-color: #e0e0e0; } .centeredcell {   align-items: center;   text-align: center; } .topleftcell {   border-right: 1px solid #e0e0e0;   border-bottom: 1px solid #e0e0e0;   background-color: #fff; }  .lettercell {   font-size: 1.5em;   color: #fff;   text-align: center; }  .nocells {   position: absolute;   top: 0;   bottom: 0;   left: 0;   right: 0;   display: flex;   align-items: center;   justify-content: center;   font-size: 1em;   color: #bdbdbd; }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
