| − | === Flexible Bounds ===
| |
| − | A normal slider can just be defined for a constant interval, i.e. the interval can't be influenced by worksheet variables. But sometimes it's necessary to create a slider for the user with flexible bounds, let's say from ''a'' to ''b''. That's not possible directly, but one can achieve a similar effect:
| |
| − | # Create a slider ''t'' in the interval [0, 1]
| |
| − | # Use interpolation to calculate the "real value" ''c'' (in the interval [''a'', ''b'']): <pre>c = a + (b - a) * t</pre>
| |
| − | # Hide the label of the slider
| |
| − | # Place a text object with the content <code>"c = " + c</code> at the old label's position
| |
| − | Such a slider works almost exactly like the normal one (exception: the label isn't moving, that needs some additional work), so your users probably won't notice.
