I have a DynamicModule with several graphic elements. I would like to create a button which would change a parameter and re-run the entire module.
Say that we have
h := Plot[Sin[k*x], {x, 0, 10}]
with an initial value of k = 1.
I want to create Button["Increase k", k = k + 1; h] that would run the plot (without using Print[h] as h is really a large DynamicModule).
This is just an addendum to jVincent's answer.
I do this sort of thing all the time when a full-bore Manipulate would be overkill. I recommend adding a Reset button and a dynamic label to make the dynamic behavior more Manipulate-like.
h := Plot[Sin[k x], {x, 0, N[4 Pi]},
PlotLabel -> Sin[k x],
ImageSize -> Medium];
btns = Row[{Button["k++", k++], Button["Reset", k = 1]}, Spacer[10]];
k = 1; Column[{Dynamic@h, btns}]
If I understand you correctly, you can simply display h in a Dynamic and then create your button to increase k, so first define your module:
k = 1;
h := Plot[Sin[k*x], {x, 0, 10}]
Then display the plot and button:
Button["Increase k", k = k + 1]
Dynamic[h]
Manipulateis used. As sample add one more parameter(g) to itManipulate[Plot[Sin[k*x + g], {x, 0, 10}], {k, 1, 10}, {g, 1, 10}]controls for k ,g are created automatically. $\endgroup$ – Rorschach Jul 14 '13 at 12:17Dynamic. AddDynamiconly tokwherever it is (pay attention to Heads) or in case ofManipulateinclude only thatButtonand maybe appendTrackedSymbols:>{ k, ...}. $\endgroup$ – Kuba♦ Jul 14 '13 at 14:08
