SetHidden and event handlers

[LoPony]

Hello!

I’m a little bit confused.
If I hide a TopLevelControl with control:SetHidden( true ), my OnUpdate-Handler stops working.

Example:

control:SetHandler( 'OnUpdate', function() OnUpdate() end )

It starts again after using control:SetHidden( false )

Does all events defined by control:SetHandler or control:RegisterForEvent stop working if the control is hidden?
Haven’t tested all the possible events and also not tested events defined by the EVENT_MANAGER.

Is this working as intended?
Is there any possibility to run OnUpdate even if the control isn’t visible (but should still update some data)?

greetings

Event handlers registered with control:RegisterForEvent will trigger regardless the control hidden status, but handler registered with control:SetHandler will not. Take "OnMoseEnter" for example - since the control is hidden how can it receive this event?

You can use EVENT_MANAGER:RegisterForUpdate(some_name, time, your_function). This function is not documented on the wiki page. It will call your_function at "time" intervals. time is in miliseconds and can be 0 to kill your framerate . Then you can call EVENT_MANAGER:UnregisterForUpdate(some_name) to unregister your handler function.

If RegisterForUpdate works, I wont need any OnUpdate handler at all.
I'll give it a try asap, thanks Harven
