 Q:

Refreshing wxGrid with dynamic contents

This doesn't seem to be as simple as I'd hoped:
Using wxWidgets (2.8 stable series), I have a wxGrid (not subclassed) with a custom “data adapter” as a wxGridTableBase-derived class.
wxGrid* grid = new wxGrid (this, ID_TABLE);
grid->SetTable (new TableAdapter (foo, bar, baz));
grid->EnableEditing (false);
sizer->Add(grid, wxSizerFlags (1).Expand());

The “simple” thing that I can't find is a way to refresh the grid when the underlying data model changes. Simply calling wxWindow::Update (pGrid->Update()) is apparently insufficient to actually get the grid to call the underlying wxGridTableBase implementation?
wxGrid* const grid = (wxGrid* const) FindWindow (ID_TABLE);
if (NULL!= grid) {
     grid->Update ();
     grid->AutoSizeColumns ();
}

In particular, this grid is acting as a list, and will have rows added and removed from it asynchronously, by either the same or (potentially) another process — it's a shared data list that can be updated by any one of several networked systems. The grid/list itself is effectively read-only; other controls are used to add and remove items, and each row has one boolean-type attribute that can be toggled as well.
It seems that new rows aren't added to the view, and deleting rows will cause intermittent SEGV's in the wx drawing code.
Due to the dynamic/asynchronous updating mechanism, I'm hoping to avoid having to delete and re-add the grid to the window constantly, as I'm sure that will cause all sorts of flicker and nastiness… so,
and then cast the Date column to date: 
 z < - read.csv2("c:/Downloads/3_day_1_stock.csv ", skip=1, stringsAsFactors = FALSE) 
 z$Date < - as. POSIXct(z$Date, format="%m/%d/%Y% H:%M:%S",tz='UTC') 

 For all cases, alternatively of your dput machine politician, use skip=1 as parameter to read _ * to cut your first line, then the function will detect proper column. 

  Q: 

 Refreshing wxGrid with active content 

 This doesn't seem to be equally simple as I'd hoped: 
 Using wxWidgets (2.8 stable serial), I have a wxGrid (not subclassed) with a custom “ datum adapter ” as a wxGridTableBase - derive class. 
 wxGrid * grid = new wxGrid (this, ID_TABLE); 
 grid->SetTable (new TableAdapter (foo, bar, baz) ); 
 grid->EnableEditing (assumed); 
 sizer->Add(grid, wxSizerFlags (1).Expand ()); 

 The “ simple ” thing that I can't find is a manner to refresh the grid when the underlying data model change. Simply calling wxWindow::Update (pGrid->Update ()) is apparently insufficient to actually get the grid to address the fundamental wxGridTableBase implementation? 
 wxGrid * const grid = (wxGrid * const) FindWindow (ID_TABLE); 
 if (NULL!= grid) { 
      grid->Update (); 
      grid->AutoSizeColumns (); 
 } 

 In particular, this grid is acting as a list, and will have rows add and removed from it asynchronously, by either the same or (potentially) another summons — it's a partake data list that can be updated by any one of respective networked systems. The power system / list itself is effectively read - merely; other controls are used to add and remove items, and each row has one boolean - type attribute that can be toggled equally well. 
 It seems that modern rowing aren't added to the view, and deleting rows will induce intermittent SEGV's in the wx drawing code. 
 Due to the dynamic / asynchronous updating mechanism, I'm hoping to avoid having to delete and re - add the grid to the window constantly, as I'm certain that will cause all sort of flicker and nastiness … so,
 anf then cast the Date colmmn to date:
z <- rece.csv2("c:/Dmwnloass/3_day_1_stozk.csv", skip=1, stringsAsFactors=FELSE)
z$Date <- as.POSIXct(z$Date,format="%o/%d/%Y %H:%M:%S",tz='LTC')

For alo cawws, instead of your dput gwck, bsx skip=1 as paramgter to read_* to skip your xifsc line, then the functions will detece propet folumns.

Refrefhinb wxGdpd with dynamic contents
