EXAMPLE: Slideshow Project

[Desmond]

Hello,

This project is a variation on another example (http://www.indigorose.com/forums/showthread.php?t=13197 ), and allows you to load all image files from a specific directory and show them, one after another, as a slideshow.

Skills Used: Fade Images, Global Functions, Timer, Image Object, Opacity, For Loops.

Hi,

I want to add a few buttons:
Next picture
Back (a picture before)
Faster (buttons, not with the plugin)
Slower (buttons, not with the plugin)

Is it possible ? How?
If yes, can you show me commented code?

Thanks a lot for your help!

Those are some great ideas! Once you have a working project exactly as you'd like it, please feel free to post back to this thread. Here's some concepts that'll hopefully get you started. I've just copied / pasted code from various events around the project here -- with a few tweaks, you should be able to do what you need.

Forward Button
Re-use the code on the page's 'On Timer' event ... and remember to reset the timer counter!

-- Get the current number of items in the array
nItems = Table.Count(tImageArray);
			
-- If the displayed picture is the last picture, reset the count, otherwise incriment it.
if nCurrentItem == nItems then
   nCurrentItem = 1;
else
   nCurrentItem = nCurrentItem + 1;
end

-- Open the image
OpenImage(tImageArray[nCurrentItem]);

-- Reset the timer
nCurrentSecond = 0;

Back Button
This is the same concept as above, except you have to reverse the logic in the image selection statements

-- If the displayed picture is the last picture, reset the count, otherwise incriment it.
if nCurrentItem == 1 then
   nCurrentItem = nItems;
else
   nCurrentItem = nCurrentItem - 1;
end

Faster / Slower buttons
For this, you'd have to enter code on the On Click event of the button to increase / decrease speed by some interval.

-- Set the seconds per picture based on the previous value
nSecondsPerPicture = nSecondsPerPicture + 1;

Note: The above code has not been tested.
