Switch Tabs Programmatically

[aslane]

Is there any way to get a list of the tabs within a Chart and/or switch tabs programmatically?

OnWindowCreated is only called once for a chart window, and I was having difficulty finding/iterating thru the tabs.

Also, would be nice to have a hot key to switch to next tab within a chart window.

Hello aslane,

Finding the TabControl of the chart is not documented in the help guide, however, it is possible to find as a child of the window.

Below is a link to the help guide for the TabControl for Addons which is the same type of object.

I am not aware of a way to programmatically change the selected tab on a chart. Would you like to submit a feature request for this?

[aslane]

The hot key should be a feature request for sure, so you can cycle thru the tabs of a window.

Hello aslane,

You may be able to set the TabControl.SelectedIndex.

Below is a publicly available link to a 3rd party site on TabControl.

Thanks, that is the direction I was headed next. First I had to get all of the tabs (originally, I was confused because OnWindowCreated is only called once per window, not once per tab). After iterating thru the tree, I have a better understanding of the structure.

Hi guys,

Just curious if anyone has some more info to post on this subject.

Aslane, do you have any sample code that you'd be able to share. I'm looking to switch to a tab based on symbol and timeframe, so for example if a tab has an alert come up by an indicator, bring up that tab automatically.

Thanks

Once you have a Chart, you can grab the tab controller and do as you want.

Chart chartWindow = window as Gui.Chart.Chart;
if (chartWindow != null)
{
        foreach (TabItem ti in chartWindow.MainTabControl.Items)
        {
            ChartTab ct = ti.Content as Gui.Chart.ChartTab;
            
            if (ct != null)
            ...
        }
}

Once you have the right tab, just set the selected index - see tab controller doc mentioned before for more.

Perfect, thank you!

aslane, how do you get the chart window? is there a way without using an AddOn?

I have 2 windows... with chart tabs.. but I don't know how to differentiate between them programatically? one is linked by instrument to the market anaylzer.. the other I manually switch the tabs because those charts have strategies running on them. However, I'd like to code something so that when the linked chart changes its instrument then I can focus in the unlinked chart window to the tab that has the same instrument (if one exists)

do you think this is possible to do?

?

If you have a chartControl (or panel) you can find the visual parent of specific type (Chart which is the chart window). You can start with

and then do something like:

Chart chartWindow = FindParent<Chart>(chartControl);
