Loop through windows

[b16_aln]

Hello,

How can I loop through all open windows and dosomething on each window.

I thought about a foreach within a dispatcher but I do not know how to access the list of open windows. I've put the foreach attempt below.

foreach(Ninjatrader.Gui.Chart.Chart win in XXXXX)
{
win.Activate();
//do something
}

I've tried "in System.Windows.Window" but this does not work.

Please can you advise how to do this and how to access the list of open windows.

Thanks

Hello b16_aln,

Thanks for your post.

Please see below for a snippet demonstrating how to loop through active windows.

foreach (var window in NinjaTrader.Core.Globals.AllWindows)
{
// check if the found window is a Chart window, if not continue looking
if (!(window is NinjaTrader.Gui.Chart.Chart)) continue;

window.Dispatcher.InvokeAsync(new Action(() =>
{
// try to cast as a Chart, if it fails it will be null
var foundChart = window as NinjaTrader.Gui.Chart.Chart;

// make sure we found a chart
if (foundChart == null) return;

// make sure the found chart is the owner window
if (foundChart != this.Owner as NinjaTrader.Gui.Chart.Chart) return;
}));
}

We look forward to assisting.

Hello Jim and thanks for the guiding solution.

I'm trying to adjust it to trigger foundChart.Focus() on the active window, from out of a quantity selector TextBox (not on the Charttrader, on the Toolbar).

I've tried that but it's not getting the Focus out of the quantitySelector TextBox and into the Chart window.

protected void ChartControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
  // FOCUS on ToolsBar's QuantitySelector TextBox
  TriggerCustomEvent(m =>
  {
    if (Keyboard.IsKeyDown(Key.Insert) && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl)))
    {
      foreach (var window in NinjaTrader.Core.Globals.AllWindows)
      {
        // check if the found window is a Chart window, if not continue looking
        if (!(window is NinjaTrader.Gui.Chart.Chart)) continue;

        window.Dispatcher.InvokeAsync(new Action(() =>
        {
          // try to cast as a Chart, if it fails it will be null
          var foundChart = window as NinjaTrader.Gui.Chart.Chart;

          // make sure we found a chart
          if (foundChart == null) return;

          // make sure the found chart is the owner window
          if (foundChart != this.Owner as NinjaTrader.Gui.Chart.Chart) return;

          if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
            foundChart.Focus();
        }));
      }
    }

  }, null);
  e.Handled = true; 

How else can I access the active window with focus? Thanks!
