Is it possible to fade out the whole screen and after a certain time to fade it in again?

Thx in adv.

Here is one example I found quickly...

Thank you, classone.

I am not interested in any solutions that need custom Plug-ins of any kind.

Sticky tape and string solution:

Grab the screen
Open a full size window with no borders
Draw the grabbed screen on the window with no transparency
Use a timer to redraw the picture at more and more transparency until all you can see if the base window.
(The base window could be white or black)

Sure, Display Services ....

Thank you mauitom and kermit.

I followed the instructions of kermit. The result looks good so far.

Just a tipp, you don't need to grab the screen. Just play with window's transparency.

But finally I decided to use mauitom's recommendation. Using quartz is a system wide solution and offers you some other options.


Thank you all again.

mauitom, I played a little with DisplayServices project which you recommended.

The screen is faded and I keep the screen black in a while loop for 30sec using the following code.

CaptureDisplayAndShowTextExample is modified so that the value of mytime is displayed at the screen.
The problem is that these value is overwritten at the same place on the screen and the background is not be refreshed.

Is there a refresh function or a draw a black rectangle function to use it before the next value of mytime comes?

It you make a call to set the text to "", this will act to clear the existing text, then make your next call to set the text to the new value. Sometimes you need to skip a few iterations inside the loop so you can read the text. I'll leave that as an exercise for you to figure out. The MOD function is one approach for this, or a simple counter is another as a flag.

I did try it before. Unfortunately it does not work. Once you draw a text, it remains on the screen. So a call with text="" does not change anything. It overwrites the screen just with "" (nothing). All numbers are on top of each other.

I think, there must be a background-refresh-function or if not, a rectangle in black may overwrite the last value. Unfortunately I can not find any function like that in the project.
