subscribing to KeyDown and PreviewKeyDown for the ChartTrader

[llanqui]

I can subscribe to these for the Chart main window

ChartControl.PreviewKeyDown += PreviewKeyDown_Event;
ChartControl.KeyDown += KeyDown_Event;

but I don't get the events when the cursor is over the ChartTrader on the right side...

how do I also subscribe to the KeyDown events when the focus is on the ChartTrader?

thx

Hello llanqui,

Thanks for your post.

We have received your question and are investigating the matter at this time.

Once we are finished investigating the matter we will update this forum thread with our findings.

Thanks for your patience.

Hello llanqui,

Thanks for your patience.

To accomplish this you would need to find Chart Trader by its automation ID.

You could consider finding the Chart Trader area grid and assigning it to a System.Windows.Controls.Grid variable called something like 'chartTraderGrid'. Then you could check if chartTraderGrid is not null and subscribe to the events, such as chartTraderGrid.KeyDown.

See the following forum post for instructions on finding an automation ID,

Note that a Dispatcher will have to be used otherwise an error will occur due to the multi-threaded nature of NinjaTrader.

Attached is a simple script that demonstrates this concept.

If the script is added to a chart, Chart Trader is enabled, a button in Chart Trader is clicked such as the Close button or Account drop-down menu, and we press the left Ctrl button on the keyboard then we see "Down" print to the NinjaScript Output window.

Ok, I have it working...now.....

can you tell me the name of the object that contains ChartWindowChartTraderControl?

I want to control its Width so it doesn't change when I move the chart...

Hello llanqui,

Thanks for your notes.

There are no supported means for controlling the width of the Chart Trader window so it does not change when the chart is resized as stated on the forum thread linked below.

should be very easy to implement

Hello llanqui,

Thanks for your notes.

I have submitted your feature request to the Development team so that they may take into consideration adding it in a future NinjaTrader release.

This request is being tracked under the number SFT-6217.

As with all feature requests, interest is tracked before implementation is considered, so we cannot offer an ETA or promise of fulfillment. If implemented, it will be noted on the Release Notes page of the Help Guide.
