I want to distribute a .cdf to my students wherein they manipulate 5 locators on a graph to define various shapes. The .cdf opens with the locators in a "nice" position, but of course it is very hard to return the locators, by hand, to these positions once they have been moved. Is there a way to utilize a "Reset" button that returns all settings to the original state? The only method I can see right now is to reopen the file in the CDFPlayer.

Your average Manipulate has the "Inital settings" button (which is just another bookmark):

Another straightforward way would be a simple button to set certain values:

Manipulate[x, {{x, 5}, 0, 10}, Button["Reset", x = 5]]

Mathematica graphics

which (as pointed out in the comments) allows for unlimited styling, for good or bad: 

Manipulate[x, {{x, 5}, 0, 10}, 
 Button[Graphics[{EdgeForm[Directive[Thick, Black]], Red, Disk[], 
    Yellow, Style[Text["Don´t\n PANIC!", {0, 0}], Bold, 40]}], 
  x = 5, Background -> None]]

  • $\begingroup$ I use the reset button method. More clear and you have more control on what to do there. Also for demo published at WRI web site, those options given in the menu above are not there. Only autorun is there. $\endgroup$ – Nasser Aug 29 '13 at 13:07
  • $\begingroup$ I, too, like the Reset button better, as it is much more clear to the user. The built in ResetButton option also works, but isn't as clear as a big button that says "Reset." $\endgroup$ – GregH Aug 29 '13 at 13:11
  • $\begingroup$ @Nasser o.k. - I only tried with the CDF preview, which shows all elements. And yes, the Button method is rather more transparent, even if the bookmarks are very useful in some cases. $\endgroup$ – Yves Klett Aug 29 '13 at 13:12
  • $\begingroup$ @GregH and of course, you can Style your Button however you wish... $\endgroup$ – Yves Klett Aug 29 '13 at 13:13

Just another way, using built-in functionality ResetButton:

Manipulate[x, {{x, 5}, 0, 10}, AppearanceElements -> "ResetButton"]
