RE: Drawing Object can't be locked programatically

PanagiotisCharalampous said: 

Hi there, 

Unfortunately we were not able to reproduce this problem. Can you please record a video demonstrating this happening?

Best regards,

Panagiotis

Here is the video I took, it's not professional looking, please volume up your speaker as my mic works poorly.

Basically, the code should (un)lock the object when it is selected. It works fine on the rectangle and others, but not on Drawing objects.  

The drawing objects just disappeared, and not possible to be found or seen on the chart anymore.  However, it is still listed in the Object Manager window.

Hopefully, this explains. 

Thanks for any advice or possible fixes.

RE: Where is my code problem on cTrader Customise Window Close and ReOpen

PanagiotisCharalampous said: 

Hi there,

If you close the window, then it does not exist anymore, you would need to reinitialize it. Once a window is closed, the same object instance can't be used to reopen the window.

Best regards,

Panagiotis

Thanks Panagiotis,
ChatGPT helped me optimised the code as below, and it works well now:
 

using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, ScalePrecision = 1, AccessRights = AccessRights.None)]
    public class TestWindow2 : Indicator
    {
        private Window wn_CWvFlt;
        private Canvas cv_canvas;
        private Button bt_Cncl;

        protected override void Initialize()
        {
            CreateWindow();
            Chart.KeyDown += Chart_KeyDown;
        }

        public override void Calculate(int index) { }

        private void CreateWindow()
        {
            wn_CWvFlt = new Window { Title = "Currency Wave...", Topmost = true };
            cv_canvas = new Canvas { Height = 600, Width = 800, Margin = "0 0 0 0", BackgroundColor = Color.FromHex("22000000"), HorizontalAlignment = HorizontalAlignment.Center, VerticalAlignment = VerticalAlignment.Center };
            bt_Cncl = new Button { Text = "Hide", Top = 500, Left = 200 };

            cv_canvas.AddChild(bt_Cncl);
            wn_CWvFlt.Child = cv_canvas;
            bt_Cncl.Click += bt_Cncl_Click;
        }

        private void Chart_KeyDown(ChartKeyboardEventArgs obj)
        {
            if (obj.AltKey)
            {
                if (obj.Key.Equals(Key.M))
                {
                    if (wn_CWvFlt == null || !wn_CWvFlt.IsVisible)
                    {
                        CreateWindow();
                        wn_CWvFlt.Show();
                    }
                }
                else if (obj.Key.Equals(Key.N))
                {
                    wn_CWvFlt?.Hide();
                }
                else if (obj.Key.Equals(Key.B))
                {
                    wn_CWvFlt?.Close();
                    wn_CWvFlt = null;
                }
            }
        }

        private void bt_Cncl_Click(ButtonClickEventArgs obj) { wn_CWvFlt?.Hide(); }
    }
}

RE: Full screen mode leaves a white line at the edge of extended monitor

Try clicking β€˜fullscreen’ F11 from a size restored window,  if I click F11 ahead of the maximised window, the whiteline will be there. Good luck!

I am having the same problem. Using ctrader fullscreen (f11) will show a large white/grey bar on the other screens:

This indicator can let you Alt+X to (un)lock objects like: ArrowLine, TrendLine, Rectangle, Icon, Text.

Hope it could be helpful.

Here is a method provided by a fellow (@TheLegitT) in the cTrader official group, though I didn't test, I believe it will work as suppose to be:

 private TimeSpan GetCurrentTimeSpan()
 {
     var TimeFrameName = Chart.TimeFrame.ToString();

     if (!int.TryParse(Regex.Replace(TimeFrameName, "[^0-9]", ""), out int prefix)) prefix = 1;

     if (TimeFrameName.Contains("Minute"))
         return TimeSpan.FromMinutes(prefix);
     else if (TimeFrameName.Contains("Hour"))
         return TimeSpan.FromHours(prefix);
     else if (TimeFrameName.Contains("Day") || TimeFrameName.Contains("Daily"))
         return TimeSpan.FromDays(prefix);
     else if (TimeFrameName == "Weekly")
         return TimeSpan.FromDays(7);
     else if (TimeFrameName == "Monthly")
         return TimeSpan.FromDays(31);
     else
         return TimeSpan.Zero;
 }

Usage:
 var CurrentTimeSpan = GetCurrentTimeSpan();

 if (CurrentTimeSpan == TimeSpan.Zero) // No supported TimeFrame available on Chart
 {

 }

 // TimeSpan is acquired properly

Sorted by creating a bool scanningComplete where at the beginning of the code and to enter the code is true, at the end of the code is false.

While, it brings another interesting issue, below screen chops are debugging in VS:
At the end of Initialize() the Bars Count is more than 7K of Bars number, but in the Calculate(), when it scans each history bar, the Bars.Count() is far less than 7K. This makes the bool ScanningComplete check many times (2K+) until it reaches 7K+ the same number as in Initialize()...

Sorted, just make a new private integer to record the Bars.Count-2, and then use it in the bool ScanningComplete check (of HistoryBar scanning).  

It runs only once and perfectly fits my request now...   
Job done!

OK, I find an alternative way:

Ctrl + D to open the object manager, key in the keyword of the object's name, then Ctrl + A to select the relevant objects only.

P.S. However, the keywords 'USD' and 'JPY' don't work in the search bar, if the chart is in 'USDJPY'.  All other currencies' names work well. It's bizarre...

Dear trader,

Our team has investigated this issue further and it seems that the feature is working as designed. The events are triggered only for interactive objects. If you want to the event to be triggered for an object added by the cBot, you need to set the IsInteractive property to true.
