I would like to validate a textinput field and have the red
boxed error message stay resident on the screen next to the field
until the data is fixed. Currently, once you move the mouse out of
the field the message goes away. I want it to stay on the screen.
I dont know for sure but here is an idea.
When you set the errorString, set the tooltip hide delay to
Infinity using ToolTipManager.hideDelay = Infinity. This will show
the tooltip forever. Upon error fixing set errorString to empty and
redefine the hideDelay to whatever your default is (eg 1000 for 1
This will of course mess up your normal control tooltips. But
if you are not using tooltips for any other purpose except error
indication, this might work.
