Dialog - check rather than ok executes if statement

[stupomer]

Hi,
I am trying to make a dialog like a fixed Toolbar i.e.

fixed in place - user can't move it around

stays on top of app at all times, always visible

doesn't register as an additional window/app in the app strip at the bottom of screen (i.e. open dialog)

Is this possible without having a separate ont statement triggered by the appearance of the dialog window

Thanks so much,

Stuart
