Cancelling Blanker causes triggering underlying button

[Deane Johnson]

When I use the "blank and blanker" choice, I get a triggering of any button underneath where I tap the screen.

In the tech paper, it indicates it should eat the first tap so it doesn't do that. Am I reading that wrong?

It should be eating any initial tap. A click should require that the actual viewer window see the initial press and the subsequent release, which shouldn't be possible if the blanker window is up since it should react to the initial press.

I'll take a look at it.

[Dean Roddey]

You are really doing blank and blanker mode, right? I.e. not just powering the monitor off? There would be a difference. If you are just powering the monitor off, there is no blanker window to eat the first click.

[Deane Johnson]

Yes, I'm using blank and blanker mode. I just went back and double checked it and tested it again.

[Dean Roddey]

Presumably this issue was fixed since then, and it's true that a lot of work went into the blanker stuff for 4.6. It doesn't happen to me on the latest code, and a lot of folks were banging on the blanker at the end to let me know if my changes were working.

[Dean Roddey]

Since you upgraded does this still happen?

[Deane Johnson]

Yes, it is unchanged. If I tap the screen to remove the blanker, the underneath widget is triggered.

I really like the feature. It's fast and does the job. Once the double action is fixed it will be a winner.

[Dean Roddey]

I'm not understanding how that can happen, at least in the latest code. I just tested it yesterday and it doesn't invoke anything under the blanker. How are you invoking it?

[Deane Johnson]

Yes, I am using "blank and blanker". To make certain, I went back and reinstalled it on the button I use to activate blank and blanker. I see the list of options has gotten longer in 4.6.9.

What I have is a small button on the screen whose action is set to "blank and blanker". Tapping it turns the screen black. I then give the screen the lightest tap I can right above a widget that opens my DVD drawer. The drawer opens every time. The button's "pressed" image also flashes as it normally would.

[Dean Roddey]

I can't understand how you could even see the button do the press effect, even if it got invoked. Is the screen coming back on and then you see the button press and un-press? That would almost have to require two click events.

What kind of machine is this on? Is it a tablet using a touch screen or a desktop with a mouse? Let's make sure that the blanker window is really coming up, and it's not just turning off the power. The only way this should be able to happen is if the blanker window really isn't showing up and all that's happening is that the screen power is turned off, so the click actually is going straight to the underlying viewer window.

Select the clock blanker mode. That should bring up the blanker window with a time display on it. It should cover the whole screen. See if that also allows you to click through. If not, then clearly in the blank and blanker scenario the blanker window isn't being displayed or it's being prematurely dismissed.

If you don't see the clock blanker that would also indicate that the blanker window isn't being displayed.
