A custom window created by an indicator.

[YuriyGulyayev]

I am prototyping the above subject.
Please find the word "PROBLEM" in the attached file.
Thanks.

[NinjaTrader_JessicaP]

Thank you for your report YuriyGulyayev. I believe this is a special case with the way modal dialogs are being handled by NinjaTrader, which are currently being reviewed. In order to track this report correctly, I have submitted a feature request to the product management team for the following feature :

This user wouldd like the Indicator Selector window to be made non-modal, to allow users to access other windows while this is open.

I will follow up with more information as soon as it's available. If the feature requests already exists, a vote will be added to it.

Please let us know if there are any other ways we can help.

Thank you for your response, Jessica.
I did not actually mean to make such a request.
What I am observing is that the new non-modal NTWindow essentially becomes the most modal one and the user must close it to make it possible to close the modal dialog.
However this behavior is not happening when instead of NTWindow I use the base WPF Window class.

[NinjaTrader_JessicaP]

Thank you for this additional information. I tested your tool on my end. I was able to determine that as long as this is a Chart window, it will obey a set of rules common to other Chart windows (if you attempt to make other NTWindows than a chart window you will see that these are unaffected) that completely user defined WPF windows will not have to follow. As such, there is no way around the behavior you are reporting without making the NS Instrument Selector non-modal.

This said, if simply documenting this fact, or any other solution, would work, please let us know. Our notes here in this thread will be made automatically available to the teams responsible for implementing features such as this.

[YuriyGulyayev]

Let me add more clarity...
If you open a few chart, press Ctrl+I to open the "Indicators" dialog, double-click my indicator, and click "Apply", a new NTWindow will show up. If you then try to close the "Indicators" dialog my clicking the [X] in its upper-right corner it will not work. You will have to close the NTWindow first.
Now, if in my code you comment out "new NTWindow" and uncomment "new Window" and repeat the same steps you will be able to close the modal dialog without first closing the newly created WPF window. So something in NTWindow implementation causes this behavior.
The window I am to develop is not going to be a chart window and simply documenting this behavior will not be very helpful. Perhaps I can work-around this by creating the new window only when the chart window gets activated, but I am trying to avoid that.

[NinjaTrader_JessicaP]

Thank you for clarifying the steps we should take to see the same thing on our end that you saw on yours. The steps you described are the steps I took earlier. The only way to resolve this query, because the NTWindow is being created inside of an indicator (and will thus be treated as a chart window) will be to change the modal behavior of the indicator selector screen. If changing the behavior of this screen so that your window can be closed without first closing the indicator selection screen is the desired behavior no further action will need to be taken on your account. With respect to the distinction between bugs and features, all modifications to NinjaTrader are prioritized based on user demand and customer impact whether they are classified as a bug or a feature. Please let us know if there are any other ways we can help.

"your window can be closed without first closing the indicator selection screen"

That is already the case, even though my window is modeless. However the opposite is not currently possible in case my indicator creates an NTWindow, but possible when it does an instance of the Window class.

Actually... I have found the problem...
You guys have hidden the non-virtual Window.Show method. I've been calling the hidden one because the CustomWindow_ field is of type Window. I changed its call to ( (NTWindow) CustomWindow_ ).Show() and it now appears to work, meaning I can close the modal dialog first. But you guys probably still need to avoid hiding the non-virtual method.

[NinjaTrader_JessicaP]

I appreciate your patience. This behavior (non-virtual Window.Show being hidden and preventing the NinjaTrader modal dialogue window for Indicator selection from closing) was confirmed on our end. We will be investigating this further. Please keep an eye on the NinjaTrader 8 Release Notes page for updates and bugfixes.

Thanks.
The following comment in your sample could be related to this:

//TODO: not sure why the .Show() isn't showing the closed window, so i'm recreating it

[NinjaTrader_JessicaP]

You are correct. This sample my colleague put together was included in this ticket for our notes, so that other technicians would have some easy to read contextual information when reviewing this ticket and be brought up to speed quickly.

[NinjaTrader_JessicaP]

I have some feedback regarding this behavior. To track user demand for this change, the following feature request has been made :

This customer would like the default result of an NTWindow’s .Show() method to be placing the window below modal windows and on top of all other NinjaTrader windows

It has been given the tracking ID SFT-2290 .

In addition, the help guide has been modified as follows :

When displaying windows with the .Show() method, the default behavior is to place the window on top of all open windows, including modal windows. To disable this please call .Show() via

( (NTWindow) MyCustomWindow_ ).Show()

Please let us know if there are any other ways we can help.

Hi, could you update the example from this post https://ninjatrader.com/support/foru...423#post787423 ?

Maybe something changed in NT8 and this code will not work in 8.0.21.0?

I import this example but see the only green button and when I click it - it happens nothing I want to create the window with settings for my indicator. But unfortunately, I couldn't run this example yet.

[NinjaTrader_ChelseaB]

Hello handlar,

I have a different example.
https://ninjatrader.com/support/foru...686#post492686

Tested and confirmed to work with 8.0.21.1.

Thank you so much, ChelseaB! I'll try to move it to my indicator

Hello
In this post

https://ninjatrader.com/support/forum/showthread.php?p=492686#post492686

we open a window with a code

if (setIndicatorValueFromAddonWindowExampleToolsWindo w == null || setIndicatorValueFromAddonWindowExampleToolsWindow .IsVisible == false)
{
setIndicatorValueFromAddonWindowExampleToolsWindow = new AddOns.SetIndicatorValueFromAddonWindowExampleTool sWindow()
{
// set an internal property of the addon to this indicator to send information back
TargetIndicator = this
};
}
// open the window
setIndicatorValueFromAddonWindowExampleToolsWindow .Show();
// bring to the top
setIndicatorValueFromAddonWindowExampleToolsWindow .Activate();

I can close it with a code placed for example in State == State.Terminated

Thanks
Massimo
