accountselector cleanup

[soulfx]

Hello, i am using an AccountSelector within an AddonBase and looking at the cleanup in handling the

accountSelector.SelectionChanged & account.Selected.AccountItemUpdate

components.

For the AccountSelector in the help it mentions the cleanup() which disposes of the AccountSelector and to call NTTabPage.base.Cleanup()

how does one do this within a class derived from AddonBase as i am not using and do not need a tab in my addon for this instance?

Also within my OnWindowCreated( Window window) within Addon base - this is where i install my addon to an existing Window .. in this case checking for window as Chart.

Now all this is working fine and i see OnWindowCreated() is called whenever a new NTWindow is created.

Is there a method within the Addon framework which will be called whenever a new tab is created within an NTwindow ? can i get a notfication for this? ie onWindowTab() .. distinct from the addon tabs?

thanks

Hello soulfx,

Below I am providing a link to an example script that demonstrates detecting when a tab is opened (added to the tab collection), closed (removed from the tab collection), selected (loaded), or unselected (unloaded).

I would recommend removing handlers from events when the TabCollection change event triggers as the tab is removed.

If the addon does not have tabs, I would recommend removing the handlers in a handler added to the unloaded event of the NTWindow.

Hi,

at NTWindow derived classes is also a eventhandler called "Closed" available. I have put all my cleanups to this handler.
Probably the Unloaded and the Closed handlers are fired at the same time when window is closing.

Thanks Chelsea, i did see this when searching forum. Given it is the chart tab collection changes i need not the addon - this gave me the insight to what i need and is working based on changes to the chart tab control.

Thanks GoSPvC - it is the AddonBase that i am using and so i have been doing the cleanup of resources and handlers in the onWindowDestroyed() which seems to be working fine ; i just wondered if there was a better/ alternate place to cleanup given this is derived from AddonBase and thus a chart window instance and not an Addon NTWindow.
