What if you want to limit the number of characters users can type in a text
field? This tip uses validation to alert your users if they type too much text
and show you how to include only a limited number of text field characters in
Reports sent by your users normally contain all fields of your app or only the
fields of the current panel. This tip demonstrates how you can select
precisely what fields to include, which cuts down on the size of the reports.
Can a formula be used to send reports to many e-mail recipients and can a
button both open a report and send it? Matt posed this question and received a
reply from our co-founder David, who shared some of our future plans for
enabling buttons to execute formulas.
Add steppers to number fields to make it easy to change their values using
plus and minus buttons. Sliders take up more space, but make it even easier to
experiment. There are also new formula functions, improved support for
embedding apps in web sites and a rewritten tour template.
If only some users need to use a large number of fields, start off by showing
only a few and give users the ability to add or remove fields using plus and
minus buttons. We demonstrate this technique using a sample app that
calculates a grade point average (GPA).
Sliders enable users to rapidly change the value of a number field within a
defined range. On mobile devices with cumbersome on-screen keypads, we expect
sliders to become the preferred way of experimenting with numeric inputs.
Steppers enable users to quickly increase or decrease numbers using dedicated
buttons, displayed next to the value. A variety of properties are available
for customizing steppers, including minimum and maximum values.
The new formula functions TONUMBER, TOLOGICAL and TOTEXT make it easy to
convert values to numbers, logical values and text strings, respectively.
Converting numbers stored as text to true numbers was previously impossible if
the number had a fractional part.
The tour template shows off many of Calcapp's features and has been completely
rewritten. The new tour demonstrates steppers, sliders, number formatting,
date calculations, cross-references and more. There's even a color selector
for the background color.
