Timer stop when window loses focus

General
1

I’ve just discovered that a timer on a window will stop when that window loses focus.
I don’t see any properties that will keep the timer running under all circumstances.
Oddly, my main window has a timer, and it keeps running when I select the problem window. But the problem window timer stops when I select the main window.
Maybe a property of the window needs to be set?

Can anyone provide more insight into the behaviour?
TIA

On a window, the timer has a scope limited to that window.

  • Drag a timer in the navigator, but not on a window
  • Add to App a property T as timer (or any other name)
  • In the App open, place

T = new CustomTimer T.Period = 1000 //Whatever you want t.Mode = Timer.Mode.Multiple // Whatever you want

Now the timer will run all the time. You can modify it and stop it from anywhere as App.T.

Alternatively, you can make T a global Module property, but the principle remains the same.

Thanks Michel. That is essential knowledge for any animate application with multiple windows!

I presume I need to also use AddHandler to specify the Action handler for the timer

Not necessarily. You can attach the Action event to the CustomTimer you have dragged into the navigator.

Just set its properties so it performs its action multiple times and whatever the period you want/need depending on usage
Nothing else required

What is the frame type of the window? That could have a bearing on the issue.
