I am making a new form using JavaFX. I need a Pop up text field within the form to add new category -


adding new category within same window

i making new form using javafx add new item inventory, if need add new category item form, must able within frame popping new text field shown in red box. there way same in javafx?

two different approaches. use textfield , seteditable(false). make textfield's seteditable(true) after double-click on textfeild. first half of code shows approach. option use label. when label double-clicked, hide label , show textfield or textarea. type data 1 of these nodes , when enter pressed, remove textfield or textarea , show text in label. second half of code show approach.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
